; Quinitio, Emilia T.
; (Wiley, 2019)
The effects of temperature and autotomy of chelipeds on survival, growth and moulting of mangrove crab (Scylla serrata) juveniles were investigated under laboratory conditions for 60 days. Hatchery‐produced crabs with ... -
Nitrogen stable isotopes reveal age-dependent dietary shift in the Japanese scallop Mizuhopecten yessoensis
Aya, Frolan; (Taylor & Francis, 2017)
Ontogenetic niche shifts in diet are a consequence of changes in body size or resource partitioning between age classes. To better resolve the feeding patterns of the Japanese scallop Mizuhopecten yessoensis, we examined ... -

Evaluation of the bioremediation potential of mud polychaete Marphysa sp. in aquaculture pond sediments
Mandario, Mary Anne; ; (Springer, 2019-10)
Organic enrichment from aquaculture could alter the chemical composition of the fishpond bottom by increasing the levels of organic matter (OM), sulfur (S), iron (Fe), and lower pH of the sediment. Polychaetes can contribute ... -
Solar irradiation as an alternative bleaching process for agar extracted from Gracilariopsis heteroclada in Iloilo, Philippines
(De Gruyter, 2019-07-30)The current industrial practice of using chemical bleach to achieve the pure white colour of agar is deleterious to both human and environmental health. This study evaluates the potential of solar irradiation as an alternative ... -
Induction of gonadal development in protogynous grouper with orally delivered FSH DNA
Palma, Peter; ; ; ; ; ; ; (Springer, 2019-08-01)
The availability of sexually mature fish often dictates the success of its captive breeding. In this study, we induced reproductive development in juvenile protogynous tiger grouper through oral administration of a plasmid ... -
Preliminary findings on supplementation of snapper fry, Lutjanus sp. with DHA-rich thraustochytrid strain, Schizochytrium sp. LEY7 showed increased growth, survival and robustness
Ludevese-Pascual, Gladys (Southern Leyte State University, 2018)
In this study, a preliminary experiment was conducted to investigate the beneficial effects of an indigenous DHA-rich thraustochytrid strain, Schizochytrium sp. LEY7 as supplement for snapper fry Lutjanus sp. using a ... -
Fish performance, nutrient digestibilities, and hepatic and intestinal morphologies in grouper Epinephelus fuscoguttatus fed fermented copra meal
Mamauag, Roger Edward; ; (Elsevier, 2019-07)
Protein enhanced copra meal (PECM®) is an alternative, cheap, and sustainable source of plant protein for the aquafeed industry, albeit its use on carnivorous fish species has been very limited. A 70-day feeding trial using ... -
Reproductive development of the threatened giant grouper Epinephelus lanceolatus
Palma, Peter; ; ; ; ; ; ; ; ; ; ; (Elsevier, 2019-05-02)
The giant grouper is presumed to follow the reproductive pattern of most Epinephelus species, characterized by protogynous hermaphroditism wherein male maturation is attained through sex reversal of a functional female. ... -

Artificial substratum consisting of poly-β-hydroxybutyrate-based biodegradable plastic improved the survival and overall performance of postlarval tiger shrimp Penaeus monodon
Ludevese-Pascual, Gladys; Laranja, Joseph Leopoldo ; Amar, Edgar ; ; (Wiley, 2019)
The use of artificial substratum consisting of poly‐β‐hydroxybutyrate (PHB)‐based biodegradable plastic for penaeid shrimp culture was investigated in the present study. The survival of postlarval tiger shrimp Penaeus ... -
Colonization of coral rubble by motile cryptic animals: Differences between contiguous versus raised substrates from the bottom
(Elsevier, 2016)Recent studies have demonstrated that interstices of coral rubble harbor rich and diverse assemblages of motile cryptic animals. Habitats of coral rubble are prone to frequent physical disturbances, so colonization is an ... -
Full-genome sequencing and confirmation of the causative agent of erythrocytic inclusion body syndrome in coho salmon identifies a new type of piscine orthoreovirus
