He's fine with the freezing weather, the pungent aromas and the occasional nip from an angry crab, but his latest problem is the big one—the worms just aren't there like they used to be. "A bad day is zero worms," said Harrington, a second-generation worm raker. "A bad day is when you try out five, six different spots and don't even make enough money to replenish the gas that you put in your tank." Harrington's struggle, and that of his fellow wormers, has reverberations around the world. A mysterious drop in the harvest of two of the most popular worms for sport fishermen is proving expensive for anglers, perilous for bait shop owners and a threat to a way of life in Maine. Maine harvesters are by far the U.S.'s largest suppliers of sandworms and bloodworms, twisty, fat critters that can grow longer than a foot and have teeth that inflict a painful bite. Wormers dig the wriggling creatures out of coastal muck so they can be sold to fishermen worldwide. The worms are especially popular with American striped bass fishermen and in Europe. An October study in the journal Fish and Fisheries said bloodworms are the most valuable marine worm species on the retail bait market, and sandworms aren't far behind. The worms, which burrow into the mud and eat things like algae and microorganisms, are coveted as bait because they are natural food to some fish. But the worm falloff has disrupted the supply chain. Maine's catch of bloodworms has dropped from more than 600,000 pounds in 2004 to less than half that last year. Sandworms dipped by two thirds, to less than 130,000 pounds. Scientists are struggling to figure out where the worms have gone. Among the factors that could play a role in the decline are rising temperatures in the Gulf of Maine, changes in currents that distribute worm larvae and increased harvesting pressure, said William Ambrose, a Bates College professor and marine researcher. It's also possible a growing number of invasive green crabs are preying on the worms, said Brian Beal, a marine ecology professor at the University of Maine at Machias. But Beal and Ambrose say more research is needed to understand what's going on. Efforts by the government to intervene have been met with resistance. A committee of the Maine Legislature this year considered a bill that would've shut down worm digging for four months a year to help preserve the industry, but it didn't pass. The proposal generated skepticism from as far away as the suburbs of Sacramento, California, where Big Red Worm Co. sells worms airmailed from Maine in boxes alongside seaweed and cooling packs. Shortening the season would be untenable, said operations manager Glenn Chadaris. "That would pretty much kill every bait shop," Chadaris said. Fishermen, too, have been feeling the sting. The price for bloodworms at the dock has more than doubled since 2001, to nearly $16 per pound, and that cost is eventually borne by consumers. Sandworms are less expensive but have similarly jumped in value. Patrick Paquette, a past president of the Massachusetts Striped Bass Association, said the retail price for a dozen marine worms has about doubled from five years ago. They typically sell for about $7 to $12 for a dozen. As a wild food source for bottom-dwelling fish, worms are especially effective for catching winter flounder in Boston Harbor's popular recreational fishery, Paquette said. But, he added, "It's extremely more expensive." Maine considers marine worms a fishery, and it's one of the most valuable in a state known for crowd pleasers like lobsters and clams. The worm harvest was worth about $5.6 million last year. Worming, which requires a $50 license, has long been an employment source in rural areas without much industry. Some fulltime diggers can make more than $50,000 in a good year, Harrington said. Others dig worms when they aren't raking clams, trapping lobsters or fishing for eels. Some suspect the lower harvest might mean fewer people are worming, but state data show the number of diggers has held steady, with 880 in 2007 and 857 last year. It's also possible the remaining diggers are doing the back-breaking work less often as they age or have a harder time finding worms. Harrington, who's been raking for 38 of his 46 years, describes his back as "a train wreck" but says he plans to stick with it. "The idea of walking in through a gate and having it close behind me doesn't appeal to me," he said. "I like to be out in nature, out in the mud."

Temperate phages are common, and prophages are abundant residents of sequenced bacterial genomes. Mycobacteriophages are viruses that infect mycobacterial hosts including Mycobacterium tuberculosis and Mycobacterium smegmatis, encompass substantial genetic diversity and are commonly temperate. Characterization of ten Cluster N temperate mycobacteriophages revealed at least five distinct prophage-expressed viral defence systems that interfere with the infection of lytic and temperate phages that are either closely related (homotypic defence) or unrelated (heterotypic defence) to the prophage. Target specificity is unpredictable, ranging from a single target phage to one-third of those tested. The defence systems include a single-subunit restriction system, a heterotypic exclusion system and a predicted (p)ppGpp synthetase, which blocks lytic phage growth, promotes bacterial survival and enables efficient lysogeny. The predicted (p)ppGpp synthetase coded by the Phrann prophage defends against phage Tweety infection, but Tweety codes for a tetrapeptide repeat protein, gp54, which acts as a highly effective counter-defence system. Prophage-mediated viral defence offers an efficient mechanism for bacterial success in host-virus dynamics, and counter-defence promotes phage co-evolution.

Blue mussels, Mytilus edulis, live on northern Atlantic shores in the area between high and low tides. "Mussels are one of the most significant filter-feeders in the marine environment," said Brian Beal, a marine ecologist at the University of Maine at Machias. "They are responsible not only for efficiently producing high-quality protein but for cleaning the waters around them through their feeding activities." Because many creatures--especially humans--enjoy eating blue mussels, farmers grow mussels using aquaculture, or aquatic farming. Beal, along with a team of NSF-funded researchers at the University of Maine at Machias and the Downeast Institute, is investigating the growing conditions and practices that will reliably yield healthy and plentiful blue mussels. The researchers also are investigating exactly when to transition the young mussels into ocean pens, and where in the pens they grow best. Find out more in this discovery. Credit: Brian Beal, University of Maine at Machias, Division of Environmental and Biological Sciences These tiny creatures are Arctic surfclams. They're getting packed up for a trip to the shore. With some help, they're about to take up residence in an intertidal mudflat on the Maine coast, or 'Downeast' as they say around here, referring to ships sailing centuries ago from Boston east to Maine and downwind. The area's rich maritime history is not lost on Brian Beal, a marine ecologist with the University of Maine at Machias who has lived here all of his life and grew up working on the water. With support from the National Science Foundation (NSF), Beal and a team based at the university's Marine Science Field Station at the Downeast Institute are putting their aquaculture innovation skills to work. The team's goals are to diversify the U.S. market for shellfish and increase the number of jobs in that market. The researchers are focused on two types of shellfish with the potential to bring more jobs and dollars to the area: blue mussels and Arctic surfclams. In the case of the latter, Arctic surfclams are not only a valuable species, but, Beal says, no one has ever tackled culturing them before. Arctic surfclams are a deepwater species that range from Rhode Island north to Newfoundland. Low densities have so far prevented the species from becoming a highly valued fishery in the U.S., but in Canada, there's a $50 million fishery off the southeast coast of Halifax, Nova Scotia, and off the Grand Banks, south of Newfoundland. The other species, blue mussels, aren't new to Maine. They've been a part of the seafood industry here for years. Beal would like to expand the market for blue mussels by making cultivation more of a turnkey operation by providing mussel growers with a choice between collecting wild seed (that depends each year on the vagaries of nature) and a more consistent hatchery-reared seedling. This is a Partnerships for Innovation: Building Innovation Capacity (PFI: BIC) project, which is focused on examining opportunities to create new marine aquaculture jobs in coastal Maine through shellfish research. The broader impacts of this research are related to increasing U.S. competitiveness in the seafood industry. "This NSF PFI project embodies a quintessential combination of science, engineering, technology, education, outreach and the pursuit of innovation," says Sara Nerlove, program director for the PFI: BIC program. "And because Brian Beal was born and raised in the area, we have a special research situation, one in which he's been able to capitalize on his thorough knowledge of the people and the local economy."

Historically, stock enhancement programs for American lobster, Homarus americanus, have a common theme: production and release of large numbers of stage IV or stage V individuals. However, these animals are difficult to mark, highly mobile when released on the bottom, and susceptible to a wide array of predators, and their claws have yet to develop bilateral asymmetry. Many of these attributes make it difficult to test the efficacy of hatch-and-release efforts. It is possible to hold postlarval lobsters individually in the laboratory or hatchery and provide food regularly for several months to release older, larger individuals (as with enhancement efforts in Europe with Homarus gammarus). However, the costs to do so compared with the value of commercial-size animals makes this practice cost prohibitive. Attempts to reduce costs of rearing early postlarvae to larger sizes in ocean-based nursery cages in eastern Maine for periods of longer than 1 y have resulted in variable survival (in general, <50%) and slow growth (doubling in carapace length (CL) from 4.28.9 mm). A series of field trials (2004 to 2010) examined methods to improve survival rates and enhance growth with the goal of producing animals large enough to apply a physical tag that can be seen easily by fishers and scientists interested in testing directly the efficacy of enhancement efforts. The effect of flow rates into and out of various types of containers (350 mL and 440 mL) holding individual, cultured stage IV lobsters was examined experimentally during a 309-day period from August 2004 to July 2005 in off-bottom, ocean-based nursery cages deployed in shallow (12 m) water near Great Wass Island, Beals, ME. Mean survival rate varied directly with flow as animals in containers with the greatest exchange of seawater demonstrated survival rates of ca. 90% compared with ca. 30% in containers allowing lower flow rates. Sediment deposition in the low-flow rate containers tended to be high, and was associated with significantly lower mean lobster survival. In a separate field trial in shallow water from August 2009 to October 2010 (419 days), lobster growth in submerged wooden trays was assessed using 5 different container sizes that ranged from 0.020.26 m 2 (ca. 1.521 L). Growth was best described by a sigmoidal function, with a strong linear component over container sizes between 0.02 m 2 and 0.13 m 2 (ca. 1.510 L), and no significant difference observed in mean CL of lobsters in the largest 2 container sizes. Final mean CL and mass (23.9 ± 1.4 mm and 10.7 ± 2.1 g, respectively, ±95% CI) of animals in the 2 largest containers was 57.4% and 349% greater, respectively, than animals in the smallest containers. Rearing cultured individuals of H. americanus to large sizes in ocean-based nursery cages may provide managers of stock enhancement programs with a more viable assessment tool than those used traditionally.

Invasive species pose a threat to biodiversity in numerous marine ecosystems, and may have severe economic effects on commercially important species. The European green crab, Carcinus maenas, is one of the most common invaders of marine ecosystems globally. Since its invasion into eastern Maine, USA, during the early 1950's, populations of the soft-shell clam, Mya arenaria, have declined greatly. This has triggered the establishment of shellfish hatcheries and the development of aquaculture techniques to enhance the wild fishery. This study investigated interactions between C. maenas and cultured juveniles of M. arenaria both in the field and laboratory. In the field (Holmes Bay, Cutler, Maine), clam (initial mean shell length [SL] ±. 95% CI: 15.8. ±. 0.5. mm; n=. 30) survival was: 1) 7. × higher in predator deterrent treatments compared to open controls; 2) not improved by using rigid vs. flexible netting; and, 3) not improved by raising and supporting deterrent netting 5. cm above the sediment surface. Wild clam recruitment was 4x greater in protected vs. open experimental units. In laboratory trials using similar sized juvenile clams, green crabs consumed clams protected by predator deterrent netting, and in one case did so without leaving visible signs of chipping, crushing, or disarticulating the valves. Physical evidence, other than crushing, may be used to differentiate between clam death due to predation vs. suffocation, disease, or other sources of mortality. © 2014 Elsevier B.V.

Along the coast of Maine, recruitment of most invasive marine ascidians follows a generalized regional pattern, with higher recruitment rates at western sites. Using artificial collectors we found that Botryllus schlosseri, Botrylloides violaceus, Ciona intestinalis, Ascidiella aspersa and Styela clava were more abundant in the western (southwestern) sites than in the eastern (northeastern) sites. This general pattern also applies to a number of other recruiting species including native mussels, Mytilus spp., and the invasive crab, Carcinus maenas. While recruitment of many marine organisms can appear stochastic in space, there can be some consistent regional patterns. Higher recruitment in the western sites of Maine may be the result of greater oceanographic dispersal due to the westward flow of the Maine coastal current, higher seawater temperatures in the west, and more anthropogenic introductions having occurred in the western harbors. © 2011 REABIC.


The commercial fishery for American lobster Homarus americanus Milne Edwards in Maine has experienced the highest landings during the past 2 decades than at any time since the 1950s. However, there is no scientific consensus on why landings have increased nearly 250% from 1990 to 2010, and no one can predict how long landings can be expected to remain at current levels. This uncertainty has sparked a renewed interest in lobster stock enhancement using cultured individuals. Historically, lobster stock enhancement in North America has focused primarily on releasing early benthic phase (stage IV) animals. It is not cost-effective to feed and maintain animals in the laboratory or hatchery until they are larger (ca. stage XXI), as is typical of enhancement efforts with cultured individuals of Homarus gammarus (L.) in Europe, even though survival to commercial size presumably would be greater. One difficulty with releasing early benthic phase animals is that they have the capacity to swim away from the release site, making tests to determine the efficacy of such programs logistically difficult and expensive. A low-cost, low-maintenance, ocean-based nursery grow-out system for stage IV H. americanus was tested in waters off eastern Maine using technology first developed and implemented successfully for cultured individuals of H. gammarus in Ireland. A single individual was added to a plastic soda bottle (ca. 350 mL) or Petri dish (440 mL) containing a series of small holes to allow continuous flow of seawater into and out of the units. Bottles (n = 630) and dishes (n = 420) were added to rigid nursery cages constructed of traditional vinyl-coated lobster trap wire and deployed in July 2002 ca. 2 m off the bottom in depths of 10 m, 15 m, and 25 m in and around Chandler Bay near Jonesport. After nearly 70 days, survival in the bottles varied from 20% at the deepwater site to 90% at the shallow-water site; however, after an additional 244288 days, most bottles had filled with muddy sediments, and mortality rate was nearly 100%. Conversely, survival rates after 448 days in the dishes varied, on average, from 21.547.2% per cage originally deployed at the deepest and shallowest site, respectively. Growth rates in the dishes generally doubled during the 14-mo field trial from a carapace length of 4.2 mm to that of 8.9 mm. Results suggest that ocean nurseries can be used to rear cultured lobsters to larger sizes prior to release for stock enhancement purposes; however, these animals are too small to apply visible tags (i.e., streamer or T-bar tags) that fishers could discern easily.

The MIST project aims to increase the success of STEM majors at the University of Maine at Machias (UMM), a small, rural, public liberal arts college with a curriculum built around issues of environmental and community sustainability. Like colleges in many rural and economically challenged regions, where educational attainment rates are significantly and chronically lower, UMM excels at providing critical education and workforce development, but science majors have lower retention and graduation rates than their peers. Persistence from the first to the second year of college has been identified as a key bottleneck limiting student success. The MIST project will transform the first-year experience for freshman science majors using practices shown to improve retention, focusing specifically on the needs of students who have risk factors associated with high drop-out rates, such as poverty, being the first in their family to attend college, or belonging to an underserved minority group. The project will build on the success of preliminary work by (1) instituting a 10-day summer program and other supports to help at-risk students transition to college, (2) restructuring tutoring services to supplement the instruction that students receive in classes, (3) incorporating more inquiry-based and problem-solving learning experiences, and (4) developing better approaches to career awareness and preparation. Increasing the number of STEM graduates will help to meet workforce demands while ensuring that students have access to rewarding and well-paid jobs locally.

The investigators will adapt key best practices to improve first-to-second-year retention rates. In particular, they will undertake the following four initiatives:

(1) Implementing a 10-day bridge program and residence hall learning communities to support transition to college and overcome barriers to attendance and success for at-risk students and underserved students (e.g., first-in-family college attendees, rural poor, and minority students). Questions to be used to measure success include: How effective are the various elements of the bridge program in (a) increasing STEM excitement and determination, (b) decreasing the need for developmental math courses, (c) creating effective study skills, and (d) increasing awareness of compelling STEM educational pathways and careers?

(2) Implementing a Supplemental Instruction (SI) program to boost student persistence and success by providing structured group instruction that is highly integrated with classroom and laboratory activities. Questions to be used to measure success include: What effects, if any, does SI/tutoring have on (a) student performance in tutored courses and (b) general MIST program goals (excitement, determination, study skills, awareness of and interest in STEM courses and careers)?

(3) Transforming instruction in all first-year STEM courses to incorporate more inquiry- and problem-based learning, career awareness, and engaging field experiences. Questions to be used to measure success include: What elements of transforming the instruction in key foundational courses (content, instructional technique, tutoring, etc.) are associated with (a) an increase in student achievement, satisfaction, confidence, and engagement and (b) first-to-second year retention?

(4) Developing career awareness and preparation activities and resources for first-year students. Questions to be used to measure success include: To what degree do the MIST career website and alumni-student exchange activities increase awareness in first-year students of STEM career opportunities and educational pathways?

This Partnerships for Innovation: Building Innovation Capacity project from the University of Maine at Machias (the easternmost of the seven campuses in the University of Maine System) examines opportunities to create new marine aquaculture jobs and new wealth in east coastal Maine through shellfish research involving two commercially important species: blue mussels (Mytilus edulis) and Arctic surfclams (Mactromeris polynyma). Currently, mussels are cultured using juveniles sourced from the wild where spatial and temporal variation in both biotic and abiotic conditions does not allow for consistent annual production schedules. Surfclams are not cultured anywhere at present, and, although present in the Gulf of Maine, are harvested commercially only in the Canadian Maritimes where they are dredged hydraulically at depths greater than 20 meters. The surfclams are flash frozen and only their feet are marketed. The proposed activities advance knowledge and understanding within the field of shellfish aquaculture involving the hatchery, nursery, and growout phases of these two commercial bivalve species that have yet to be produced in shellfish hatcheries in the U.S. The research effort will yield information critical to other researchers and commercial businesses about the parameters that affect growth and survival of each species from early to later life-history stages.

The broader impacts of this research are related to increasing U.S. competitiveness in the seafood industry. For example, since 1990, U.S. mussel imports have increased from 2,600 tons to more than 15,000 tons. Over 90% of the imports come from two countries, New Zealand and Canada, because the domestic supply is inadequate to keep up with consumer demand. Other impacts involve mentoring undergraduate students in teaching, training, and learning through hands-on hatchery and field-based activities that will broaden participation of underrepresented groups (academic and geographic). The academic-small business partnership is fundamental to the shellfish research that creates a stronger, more efficient research infrastructure. As configured, this partnerships will lead to commercialization activities that are sustainable and compatible with the cultural heritage and ecological values of downeast Maine. PI Beal (a Fulbright Scholar) and co-PI Shumway (an Aldo Leopold Fellow) have extensive experience bridging the gap between industry and academia and will be active in the project as well as in outreach activities.

Partners at the inception of the project are the lead academic institution, University of Maine at Machias, a public, undergraduate institution of 1,000 students and 100 employees in eastern Maine; and three primary, small technology-based business partners: AC, Inc (Beals, ME), the largest wholesale seafood business in eastern Maine with 23 employees; New DHC Inc. (Machiasport, ME), a salmon aquaculture company in eastern Maine with 55 employees; and, Pemaquid Oyster Company, Inc. (Waldoboro, ME), a shellfish aquaculture company with 6 employees. Other academic and governmental partners include the University of Connecticut, Department of Marine Sciences (Avery Point, CT); Two branches of National Oceanic and Atmoshperic Administration (NOAA): National Marine Fisheries Service (NMFS) in Milford, CT; and National Centers for Coastal Ocean Science (NCCOS) in Charleston, SC.
