Settlement, growth and survival of donkey's ear abalone Haliotis asinina (Linne) in response to diatom diets and attachment substrate
(Science and Technology Information Institute, 2010)
The effect of feeding four diatom diets (Amphora sp., Navicula ramosissima, Amphora sp. + N. ramosissima, and mixed diatoms) and two attachment substrates (PP+CCA: polyvinyl plates with crustose coralline algae; PP-CCA: ...
Effects of dietary l-tryptophan on the agonistic behavior, growth and survival of juvenile mud crab Scylla serrata
(Elsevier, 2010)
The reduction of the survival of mud crab during culture has been largely attributed to aggressive encounters and cannibalism. In some crustaceans, suppressed aggression is linked to increased concentration of circulating ...
Prevalence of viral nervous necrosis (VNN) virus in wild-caught and trash fish in the Philippines
(European Association of Fish Pathologists, 2011)
Viral nervous necrosis (VNN) caused by piscine nodavirus is a devastating disease affecting mainly marine finfish. In the Philippines, VNN was first reported in hatchery-reared grouper (Epinephelus coioides) broodstock in ...
Netcage rearing of the Asian seabass Lates calcarifer (Bloch) in brackishwater pond: The technical and economic efficiency of using high protein diets in fingerling production
(College of Agriculture, University of the Philippines Los Baños, 2012)
Intensification in the grow-out culture of high-value fish requires a large quantity of quality fingerlings. Fingerling production is a component of fish farming that comprises nursery and grow-out culture, and may be a ...
Dietary onion and ginger enhance growth, hemato-immunological responses, and disease resistance in brown-marbled grouper, Epinephelus fuscoguttatus
(Bioflux, 2012)
A 12-week (September to December 2009) feeding trial was conducted to evaluate theimmunostimulatory effects of different substances administered orally through the diet in the brown-marbled grouper, Epinephelus fuscoguttatus. ...
Survival and growth of mud crab, Scylla serrata, juveniles subjected to removal or trimming of chelipeds
(Elsevier, 2011)
The effects of removing or trimming the chelipeds at various molt stages on regeneration, molt interval (MI) and specific growth rate (SGR) were determined in mud crab Scylla serrata. These strategies in combination with ...
Skip feeding as an alternative strategy in the production of Nile tilapia Oreochromis niloticus (Linn.) in cages in selected lakes in the Philippines
(College of Agriculture, University of the Philippines Los Baños,, 2012-12)
Many inland water bodies in the Philippines are currently used for fish cage culture. Inappropriate practices including feed management in aquaculture results not only in the degradation of water quality but also in economic ...
Resistance of rainbow trout Oncorhynchus mykiss to infectious hematopoietic necrosis virus (IHNV) experimental infection following ingestion of natural and synthetic carotenoids
(Elsevier, 2012)
Further to previous studies showing modulation of innate immune responses by dietary carotenoids, an experiment was conducted to examine the resistance to a viral pathogen in rainbow trout after oral ingestion of synthetic ...
Effect of different mangrove-to-pond area ratios on influent water quality and WSSV occurrence in Penaeus monodon semi-intensive farms using the greenwater culture technique
(Elsevier, 2012)
White spot syndrome virus (WSSV) has been affecting the shrimp industry worldwide for two decades now. It continues to bring economic losses to affected farms. Despite the many studies on its epidemiology, there is no ...
Size measurement and nutritional condition evaluation methods in sandfish (Holothuria scabra Jaeger)
(Wiley, 2012)
The aims of this study were to establish an accurate size measurement method and a nutritional condition evaluation method of Holothuria scabra (Jaeger). Although 0.5% KCl and 0.05% MgSO<sub>4</sub> did not induce anaesthesia, ...
