The University of the Philippines Visayas, also known as UPV and UP Visayas, is a public research university in the Philippines, and one of the units of the University of the Philippines System. It is one of the most prominent educational institutions in the Visayas, especially when it comes to management, accountancy, marketing, economics, chemistry, applied mathematics and physics, marine science education and research, fisheries, and aquaculture. It offers regional studies programs on the preservation and enrichment of the Visayan cultural heritage as well as a full complement of other subjects and majors.U.P. Visayas has three campuses--Miagao, Iloilo City, and Tacloban—with Miagao being the main campus with its central administration offices. The University of the Philippines Cebu College was part of UP Visayas but it separated in September 2010,.Most of UPV's students are drawn from the Visayas and the Visayan linguistic groups. Many of the leaders of the Visayas have graduated from U.P.V. or its predecessor institutions.As of 2007, the Philippines' Commission on Higher Education awarded four National Centers of Excellence/Development to UPV including Fisheries , Marine Science , and Biology .

The Guimaras oil spill of 2006 was the worst environmental accident of the Philippine and coincidentally happened during a period of rapid progress in nationwide communication technology. This study took advantage of the massive media coverage of the incident to answer questions about the priority needs of the affected population, the prominent disaster response, and the rationale for the response. Techniques were combined to implement a descriptive analysis of the available information-interview of key respondents and news survey, substantiated by a document analysis of hardcopy and online materials, and content mapping in the integration and analysis.The priority needs of the oils spill victims were few and basic-a plain consequence of economic and physical dislocations. Yet, these needs were inadequately met because the many forms of disaster response "diluted" the relief operation and further spawned unwarranted issues that aggravated the situation. Habitat assessment and rehabilitation, especially of mangroves, emerged as the prominent response. Aggressively pushed by experts and advocates, it competed with and overshadowed the priority action on the distressed population.The environmental response is linked to a lingering foreign crusade. The environmentalism is unregulated and turning adverse, but it continually succeeds because, apart from its domineering advocacy, as foreign imposition, the society is naturally resilient to it, Philippine laws support it and, particularly, even intellectuals espouse it. Moreover, there exists a large pool of potential environment advocates in the country with hardly 1% of which being development-oriented.Other failures of the disaster response are discussed. The aftermath rippled with issues on litigations, irregularities and continuing research. © 2014 Elsevier Ltd. Source


A feeding trial was conducted for 12 weeks to evaluate the potential use of legume-based diets supplemented with dietary microbial phytase on the growth performance and feed efficiency of juvenile sea bass, Lates calcarifer. Fifteen sea bass juveniles (mean initial weight of 0.96 g and mean initial total length (TL) of 4.2 cm) were stocked at three replicates into each of the twelve 100 L conical fibreglass tanks containing 90 L sea water in a closed recirculating system with filtered and aerated sea water. Four isonitrogenous, isolipidic and isocaloric experimental diets were formulated. The control diet (C0) contained fish meal, soybean meal, shrimp meal and squid meal as major protein sources. Legume seed meals of pigeon pea (Cajanus cajan), yellow mungbeans (Phaseolus aureus), and green mungbeans (Vigna radiata) were incorporated in the practical diets D1, D2 and D3 respectively at 18-20% replacing an equivalent amount of 6-7g fish meal protein and supplemented with microbial phytase at the level of 300U kg-1 diet. Growth rate, feed conversion ratio (FCR), protein efficiency ratio (PER) and apparent net protein utilization (ANPU) of sea bass were significantly (P < 0.05) higher in control diet than those given different legume based diets supplemented with phytase. Histological examination of the liver tissues for the different dietary treatments did not manifest any abnormalities. Phytase supplementation also improved bone ash, phosphorus (P) concentration as well as P content in the carcass for fish in legume fed groups. Results from the present study showed that incorporation of dietary microbial phytase in legume based diets slightly improve the growth performance and P availability in sea bass juveniles. Source

A 12-week feeding trial was conducted to investigate the effect of green pea P. sativum as alternative protein source for fish meal on the growth performance, feed utilization and phosphorus excretion for Asian sea bass, Lates calcarifer. Four isonitrogenous (40% crude protein) and isolipidic (10% lipid) diets were prepared with the increasing substitution levels of green pea (GP) for fish meal (FM) at 0% (P0), 10% (P10), 20% (P20) and 30% (P30) with corresponding dietary protein levels at 0, 2.6, 5.2 and 7.8% respectively in a 40% protein diet. The weight gain (WG) of fish (19.69 g) fed P0 diet (control without GP meal) was comparable to fish fed P10 diet (17.75 g) but significantly (p < 0.05) higher than those fish fed P20 (14.62 g) and P30 (13.17g) diets respectively. Fish fed P30 diet had the lowest value for WG which might be attributed to the poor palatability of the diet as sea bass obviously ignore the pellets offered during the feeding. Partial replacement (about 10%) of fish meal in P10 diet produced fish with feed conversión (FCR) and protein efficiency (PER) comparable to the control fish but significantly higher (p < 0.05) than that of fish fed P20 and P30 diets. Fish fed control diet had the highest survival (93.33%) and feed intake (41.40 g/fish). These results were comparable with sea bass fed P10 diets (93.33%; 38.34 g/fish). The decrease in the percentage protein in the carcass was associated with the increasing dietary levels of GP in the diets. No significant differences (p > 0.05) were found in the percentage of lipid among the different treatments. The peak time for phosphorus excretion was observed after the first feeding at the end of 8 hrs. Fish fed P0 diet had the highest phosphorus excretion which was attributed to its high level of FM component whereas fish fed P30 diet had the lowest. It appears that green pea can replace fish meal at the level of 10% in diets for sea bass without adverse effects on growth, feed utilization or body composition and this may also contribute to environmental protection as well as reduce feed cost to sustain aquaculture.

The ontogenetic pattern of an endopeptidase (chymotrypsin) and two exopeptidases (carboxypeptidases A and B) in larvae of the mud crab, Scylla serrata, are described. Specific activity of chymotrypsin was detected in all larvae stages. The activity was about 25% of the maximum at stage Z1, doubled at Z2 and Z3, declined to 40% at Z4 and Z5, abruptly increased to maximum activity during the megalopa stage, and fell to about 33% at the first crab stage, CI. Carboxypeptidase A activity was low at Z1, gradually increased from 4% to 13%, 19%, and 27% of the maximum at Z5, markedly increased to 68% at the megalopa stage, and finally peaked at CI. Carboxypeptidase B activity started at 9%, declined to 4%, abruptly increased to almost 50% at Z3, remained high at Z4, Z5, and the megalopa stage (50%, 61%, and 50% of the maximum), and finally peaked at CI. The overall changes could be related to changes in diet and feeding habits, or to behavioral, mechanical, and physiological changes, or their combination during development of S. serrata larvae.

Common carp were fed diets containing various levels of Quillaja saponins (QS) (0, 150, 300 and 450 mg kg-1 dry diet) in a completely computerized respirometric system for 4 weeks. Fish fed diets containing QS exhibited significantly higher ABW and specific growth rate than did those fed the control diet; those fed diets containing QS 150 grew fastest but were not significantly different from those fed diets with QS 300 and QS 00450. All the utilization efficiency indices, namely food conversion efficiency (FCE), protein productive value and PG were increased by QS supplementation. There were no significant differences in the average routine metabolic rate between treatments, indicating that dietary QS at the levels tested were not toxic to the carp. Increases in amylase and trypsin specific activities were observed at QS 300 and QS 450. Enzymes of carbohydrate metabolism such as G6PDH, 6-phosphogluconate dehydrogenase and pyruvate kinase were not significantly affected by dietary QS. Activities of the aerobic enzyme Cox and to a limited extent that of the anaerobic enzyme lactate dehydrogenase were significantly increased by dietary QS but the net effect was a shift towards aerobic metabolism, indicating absence of stress and favouring the anabolic processes. Thus, Quillaja saponin was beneficial as a feed supplement in the common carp. © 2012 John Wiley & Sons Ltd. Source
