Most of the inhabitants of the Karbi-Anglong district of Assam, survive on their traditional knowledge base. Livelihood of the people is bound by traditions and the community in general is relatively untouched by modern scientific knowledge on fisheries and allied sector. Documentation and compilation of indigenous technical knowledge (ITK) is of great importance. In the study, a total of 100 fishermen from four blocks were interviewed using pre-tested interview schedule. Accordingly, the study has documented some unique indigenous knowledge related to fish harvesting. ITK regarding fish harvesting, fishing with attractant, piscicidal plants, community fishing, wounding gear and bana fishing were documented. Under fishing with attractant, matia chali, kalpotua chali, pot fishing and crab fishing were documented. Under plant piscicides, smartweeds, karoi tree and moin, were documented. Under community fishing, scare fishing and dalbandhi maach mara were documented.

The satellite-based vessel monitoring system in the Norwegian Economic Zone provides detailed information about individual trips by vessels. Vessel sizes are available through official registries, and the storage capacity for fish is estimated using the established conversion factors as a function of the vessels gross registered tonnage. Scientists have had access to the database of both transport and fishing vessels, with records for individual trips, in addition to information about the total round weight (whole fish) of cod and haddock for trips inspected by the coastguard. The analysis assumes that trips with complete documentation of the fish on board are a random sample, so allowing estimation of the mean amount of both cod and haddock per trip, and annual totals give the number of trips per vessel annually. ICES has accepted this methodology for estimating illegal, unregulated, and unreported (IUU) catches, which has resulted in 15 000 - 166 000 t (3-35%) being added to the officially reported landings of Northeast Arctic cod during the years 2002 - 2008. IUU landings have decreased in recent years, but are so important for assessment and management that estimates continue to be made annually. © 2011 International Council for the Exploration of the Sea.

Fisheries have been important for livelihood in Norwegian coastal communities for centuries. The development of new fishing technology and increasing fishing capacity posed challenges for the sustainability of the fisheries. The Norwegian spring spawning herring was depleted in the1960s - with dire consequences. This event, and the subsequent efforts to rebuild the stock, was paramount to the gradual development of a coherent Norwegian policy to prevent overfishing and secure long-term sustainability. Nevertheless, overfishing continued during the ensuing transitional decades when a range of new management tools were developed and made effective. Internationally, the extension of the economic zones to 200 nautical miles, and agreement on sharing and management of joint stocks were important elements. At the national level, the development of measures to curb overcapacity, improvement of exploitation patterns through technical regulations, ban on discard and the evolution of procedures for rational decision-making for setting total allowable catches (TACs) on the basis of harvest control rules, were all decisive elements. Another crucial factor was the creation of a whole new profession of fishery inspection. We describe a system of close collaboration between specialists - scientists, fishery managers, and stakeholders - each with a distinct role in building a solid framework to prevent overfishing and secure long-term sustainability. © 2013 © 2013 International Council for the Exploration of the Sea.

AKVA group completed third quarter with good overall performance. Revenue in the third quarter of 2016 ended on 354 MNOK (355 MNOK) with an EBITDA of 38 MNOK (41 MNOK). Third quarter EBITDA margin was 10.8% (11.4%). The P&L growth in the quarter was softened by slow operations in Americas and by restructuring of AKVA group Denmark A/S. The growth strategy in AKVA group continues with the acquisition of Sperre AS, a leading ROV and subsea provider to the aquaculture industry, as well as investments in increased capacity in Helgeland Plast AS and increased presence in the Mediterranean. AKVA group is ending the quarter with the highest order backlog ever of 886 MNOK. "AKVA group continues to deliver stable high margins despite the challenges we face in Americas and in AKVA group Denmark A/S this quarter. The recent year's transformation of AKVA group to become a better performing and more diversified Group is reflected in the Q3 results. Our growth strategy continues with the recent acquisition of Sperre AS, investments in Helgeland Plast AS as well as extension of our activities in the Mediterranean. Operationally and financially AKVA group is well positioned for further growth. This is also underlined with the highest order backlog ever at the end of a quarter", says CEO of AKVA group ASA Trond Williksen. Cage Based Technology (CBT) Nordic CBT had a good performance in Q3. A wide range of products continues to contribute to the financial performance. Helgeland Plast AS continues with good performance this year and the Farming Services area with AKVA Marine Services AS is also performing well. We have experienced reduced activity in Americas this quarter compared to same quarter last year resulting in a reduction in EBITDA year on year of 8.7 MNOK in Q3. There has been low activity in Chile in Q3 due to reduced service and technology sales in a challenging market caused by uncertainty of future direction and regulatory regime, now finally about to be resolved. We have over the last years reduced our financial exposure in Chile significantly. The Chilean operation is now leaner and well prepared for an upturn in the market when this happens. Canada had another unusually slow quarter. Australia continues to be a small, but profitable operation. UK had a decent quarter and continues to have a high level of OPEX based revenue. Turkey continues with another very good quarter. We are experiencing increased activity in the Sea Bass and Sea Bream industry in the Mediterranean. Export to emerging markets have a relative low, but profitable operation in Q3. Emerging markets are dominated by a few but large contracts and this will continue to give variations in the P&L quarter by quarter. Software (SW) Software has ended another good quarter. Both AKVA group Software AS and Wise lausnir ehf experienced improved performance year on year in Q3. The software segment also have improved performance year on year YTD, both on topline and in margins. Software continues to invest in new product modules, which is expected to strengthen the financial performance of the software segment further. Land Based Technology (LBT) There have been good financial performance in Aquatec Solutions A/S and Plastsveis AS in Q3 and the high market activity continues. However, Q3 was a weak quarter for AKVA group Denmark A/S. New management has initiated needed efforts to make the unit more efficient. This restructuring have resulted in a negative EBITDA of MNOK 4.9 in Q3. The work to improve and make this a more streamlined entity continues into Q4. The land based segment ended the quarter with a high order backlog which represents 47% of the total order backlog in the Group at the end of Q3 2016. The land based segment increased its revenues year on year with 85% and contributed 22% of total revenues in Q3 2016, hence land based is becoming a significant part of AKVA group. Order Backlog We have experienced continued good market activity throughout the third quarter of 2016. The order inflow in Q3 2016 was 417 MNOK (505 MNOK). Underlying operational order inflow (adjusted for the one time intake of the order backlog of Aquatec Solutions in Q3 2015) increased from 318 MNOK to 417 MNOK in the quarter. The order backlog at the end of Q3 2016 was 886 MNOK (643 MNOK). This is the highest order backlog ever for AKVA group. Balance sheet The balance remains strong. Working capital as a percentage of 12 months rolling revenue is 8.8% (9.1%). We are able to maintain a very low working capital despite record high activity. Cash and unused credit facilities amounted to 165 MNOK at the end of Q3 (226 MNOK).Total assets and total equity amounted to 1,179 MNOK (1,163 MNOK) and 438 MNOK (443 MNOK) respectively, resulting in an equity ratio of 37% (38%) at the end of Q3. Acquisition of Sperre AS - the leading ROV provider Sperre AS will be the "center of excellence" in AKVA group in terms of ROV technologies as well as relevant subsea technologies. The intention and ambition is to develop an undisputed industrial leadership in the ROV and subsea technology area within aquaculture. AKVA group ASA acquires 66% of the shares in Sperre AS. The closing of the transaction will take place on November 4th, 2016. The enterprise value for all the shares in Sperre AS is NOK 126.9 million. In addition, AKVA will pay an adjustment amount based on the net debt and working capital position at closing. AKVA group ASA have an option to buy the remaining 34% of the shares after three years, where the pricing is based on financial performance in the three year period. The acquisition will be paid in cash and will be financed with a loan from Danske Bank. Changes in operational structure From August 2016 and onwards land based technologies was carved out as a new Group entity. The entity is headed by Morten Nielsen who became a new member of the Group management team, responsible for all land based operations in AKVA. In addition, Morten Nielsen also holds the roles as General Manager in both Aquatec Solutions and AKVA group Denmark. Sperre AS will be included as a new unit in the Nordic cage based segment of AKVA group. Expansion into the Mediterranean - new office in Spain We now see positive signs in the Sea Bass and Sea Bream market in the Mediterranean. AKVA group is therefore about to establish a new office on the east coast of Spain. We will have service resources on the ground to support our customer base. This office will strengthen our presence and position in the Mediterranean region. Deliveries into Iran AKVA group has worked actively in Iran for the last 2-3 years and we have now delivered the second cage farm in this market to Bushehr Aramseyd Co. Reysali Delvari Dam. We are doing sales of both cage based and land based technology into Iran. These are equally big markets, i.e for cage based and land based technology. The Iranian Government strategy is to grow cage farming by 200.000 tons in 5 years (Barramundi, Sea Bream, Rainbow Trout, Sturgeon, etc). The Government is already issuing licenses, providing financing and setting deadlines for starting-up production. Atlantis Subsea Farming AS In partnership with the companies Sinkaberg-Hansen AS and Egersund Net AS, AKVA group ASA established the company Atlantis Subsea Farming AS on February 1st, 2016 with the purpose of developing submersible fish-farming facilities for salmon on an industrial scale. Atlantis Subsea Farming AS has applied for six development licenses to enable large-scale development and testing of the new technology and operational concept. Atlantis Subsea Farming AS is in dialogue with the Directorate of Fisheries and we are waiting for a final resolution on the issue of development licenses. Outlook We have a good mid-term outlook due to high market activity and the large order backlog. The good demand in the Nordic cage based segment continues. The land based activity in AKVA group is growing. This trend is expected to continue and the land based segment is becoming a larger part of AKVA group. UK and Europe is expected to perform well going forward with a growing order backlog. Canada experienced less project sales so far compared to last year and we have moderate expectations in this market going forward. We still have low expectations in Chile, but there are now clear signs of improvement in this market. Our exposure in Chile is reduced compared to prior years. Our Turkey and Australian operations are expected to continue to perform well in the next quarters with a good order backlog. Exports to emerging markets have a more optimistic view compared to last year. However, the activity is still expected to fluctuate due to the nature of the business. AKVA group continue to actively seek strategic M&A opportunities within relevant segments. We continue our effort to build service and after sales as a key business element in all our markets and segments. About AKVA group AKVA group is a technology and service partner to the aquaculture industry worldwide. The company has 768 employees, offices in 8 countries and a total turnover of NOK 1.4 billion in 2015. We are a public listed company operating in one of the world's fastest growing industries and supply everything from single components to complete installations, both for cage farming and land based aquaculture.

This study investigated the presence of total mercury (Hg) and organic mercury levels in the muscle of 19 common fresh water fish species captured from river Ganges, West Bengal, India. The total mercury level found in our study may not cause any toxic effect, but the methyl mercury (MeHg) level in some freshwater fish species was surprisingly very high and toxically unacceptable. The results of mercury analysis in various specimens indicated that some fish muscles tended to accumulate high levels of Hg, and approximately 50-84% of Hg was organic mercury. A strong positive correlation between mercury levels in muscle with food habit and fish length (age) was found. Wallago attu possessed the highest amount of organic mercury in their muscle tissues, and it was 0.93±0.61 μg Hg/g of wet weight. Whereas in small-sized fishes Eutropiichthys murius, Puntius sarana, Cirrhinus mrigala, Mystus vittatus or Mystus gulio, and Tilapia mossambicus, it was below the detection limit. Contamination in Catla catla (0.32±0.11), Anguilla bengalensis bengalensis (0.26±0.07 μg Hg/g), Chitala chitala (0.25±0.18), Rita rita (0.34±0.14), and Ompokpabda (0.26±0.04) was also above the 0.25 μg Hg/g of wet weight, the limit set by the PFA for the maximum level for consumption of fish exposed to MeHg. Though in Labeo rohita (0.12±0.03), Mastacembelus armatus (0.17±0.02), Pangasius pangasius (0.12±0.16), Bag-arius bagarius (0.12±0.01), and Clupisoma garua (0.1±0.01), concentration was below the recommended level, in Lates calcarifer (0.23±0.0) and Mystus aor (0.23 ±0.1), it was threatening. Interestingly, a low concentration of Hg was found in post-monsoon samples. © Springer Science+Business Media B.V. 2011.

Seasonal abundance, composition and grazing rates of microzooplankton (20–200 µm) in the Zuari estuary were investigated to evaluate their importance in food web dynamics of a tropical monsoonal estuary. Average abundances of microzooplankton (organisms × 104 l−1) during the three seasons were 0.44 (southwest monsoon), 1.13 (post-monsoon) and 0.96 (pre-monsoon). Protozoan (ciliates, heterotrophic dinoflagellates and sarcodines) accounted for most (96 %) of the microzooplankton community, with micrometazoan (nauplii and copepodid stages of copepods, fish eggs, etc.). being far less abundant. Among protozoans, ciliates (loricates and aloricates) were most numerous (69 % of the total microzooplankton). Statistically significant (p < 0.001) co-variations of microzooplankton with other biological parameters such as chlorophyll a and bacterial biomass were observed. Salinity influenced microzooplankton distribution, with an optimum range of 15–20. Microzooplankton formed a large organic carbon pool, accounting for 24–40 % of the total carbon in the living matter. Seasonally averaged microzooplankton biomasses were 22.3, 36.1 and 24.6 mmol C m−3, respectively, during the southwest monsoon, post-monsoon and pre-monsoon periods, and were largely supported by non-living particulate carbon (detritus) particularly during the non-monsoon seasons. Experimental studies revealed significant microzooplankton grazing on phytoplankton standing stock, mainly (>60 %) by the pico and nano fraction (<20 µm) for most of the year. Phytoplankton growth rates (day−1) ranged between 0.69 and 1.24. Microzooplankton grazing was estimated to consume 30–82 % of the phytoplankton standing stock, and 58–97 % of the daily primary production. Results of the present study highlight the role of the microzooplankton as an important consumer of phytoplankton production. © 2015, The Oceanographic Society of Japan and Springer Japan.

The Pabdah catfish, Ompok pabda, was successfully spawned with the synthetic hormone Ovatide at two different doses (0.4 and 0.6 ml/kg of body weight of female). The latency period was 9-10 h at 0.6 ml compared to 10-12 h at 0.4 ml kg -1 of body weight. All the females spawned successfully. Average rate of fertilization (75.5 %) and hatching (60.5%) was higher with a dose of 0.6 ml kg -1, while lower fertilization (65.1%) and hatching rate (45%) were observed at 0.3 ml kg -1 of body weight. Fecundity ranged from 80-130 eggs gm -1 body weight of female. Eggs hatched between 12-14 h after spawning at a water temperature 28°-32°C. The mean egg diameter was 0.95 ± 0.15 mm. © 2012 Copyright National Bureau of Fish Genetic Resources, Lucknow.

This study is an attempt to study the fishery resources and fisheries in Basra province in Iraq, during 1990 to 2011. The declared catches by fishermen and fish market were used in this study. The total commercial catch peaked in 2009 at 4.390.775 and 152.445 ton for Marine and Freshwater fishes respectively. Species composition of catches was studied during the above period. About twenty nine marine and thirteen freshwater fish species were recorded. The total catch of the marine fishes was dominated by Tenualosa illisha. It accounted for about 45 % of the total catch during whole period. The freshwater fishes was mainly represented by (Silurus triostegus) which accounted for 32% of the total during whole period. Gill net's fishing method was employed mainly for catching pelagic fish, trawling is single largest technology being practiced in the region for harvesting the demersal fishes. Overfishing was perceived as a serious problem and needs to, be taken into account in considering risks to the stock of the fishes. The weather patterns, market prices and environmental conditions (natural or human-made) have a significant effect on fish stock. Moreover, increases in water salinity and pollution level has also a significant impact on fish stockand therefore, the enforcement of the new standards for Environment Pollution Control in the province is required.

Bergen, Norway, Nov. 28, 2016 (GLOBE NEWSWIRE) -- On 10 February 2016 Marine Harvest applied for 14 development licenses in relation to the concept "the Egg". The Egg represents a new enclosed technology within salmon farming and has many advantages to conventional farmed salmon production in regards to minimize environmental impact and increase value creation. The Norwegian Directorate of Fisheries has now informed Marine Harvest that the Egg concept qualifies in general for the development licenses scheme and that they may award four development licenses for this project. Marine Harvest is very pleased with the positive feedback from the Directorate of Fisheries and we are encouraged to see that the authority shares our view that the Egg concept represents a new technology which may contribute to move the salmon industry forward. We will continue to work with the authorities, and hope they will reach a final conclusion imminently in order for the project to commence. To date Marine Harvest has applied for 34 development licenses for four concepts.
