Grazing periodicity, grazing rate, feeding preference, and gut examination of early juveniles of abalone Haliotis asinina–fed five benthic diatom species
(Springer, 2022-06-03)
This study evaluated the suitability of five diatom species (Amphora sp., Cocconeis sp., Navicula ramosissima, Nitzschia sp., and Tryblionella sp.) as food to abalone Haliotis asinina early juveniles (5-mm shell length). ...
Intracellular production of recombinant GnRH1 in yeast, Pichia pastoris, and its potential as oral treatment to advance gonadal development in juvenile orange-spotted grouper, Epinephelus coioides
(Elsevier, 2022-05)
Late maturation and large size at maturity are significant challenges when administering hormonal treatments in captive broodstock. Here, we report the potential of yeast, Pichia pastoris, as a vehicle to orally deliver a ...
Settlement of oyster Magallana bilineata (Röding, 1798) spat in the natural environment: Seasonality and substrate texture preference
(Malacological Society of Australasia; Society for the Study of Molluscan Diversity; Taylor and Francis, 2022-05-12)
This study determined the seasonality of Magallana bilineata spat settlement in a natural oyster bed and established surface texture preference of competent larvae by comparing the numbers of spat settling on the smooth ...
Seasonal growth, organ indices and food consumption of the Japanese scallop Patinopecten yessoensis (Jay, 1857) in relation to food availability in Tokoro seabed, Okhotsk Sea, North Japan
(The Plankton Society of Japan (The Japanese Association of Benthology), 2022-05-30)

Bacterial microbiota of hatchery-reared freshwater prawn Macrobrachium rosenbergii (De Man, 1879) and their pathogenicity
(University of the Philippines Visayas, 2022)
Quantitative and qualitative analyses of bacterial microbiota associated with hatchery of Macrobrachium rosenbergii (de Man, 1879) were conducted over three larval cycles, along with important water quality parameters. ...
Characterization of wild eucheumatoids from Visayas, Philippines as inferred from the mitochondrial cox2-3 spacer sequence
(University of the Philippines Visayas, 2022)
Eucheumatoids are the major seaweed species cultivated in most coastal areas in the Philippines, being a major source of income for many families. Seaweed farmers face issues such as lack of good quality cultivars and the ...
Improving artisanal fisheries through community-based prawn stock enhancement in a mangrove estuary
(Japan International Research Center for Agricultural Sciences, 2022)
Tropical seafood, especially prawns, have always been in high demand with high market prices. Because of this, wild prawn resources are often overfished as indicated by the increasing number of fishers, but with overall ...
Innofloc: Innovative biofloc technology for the nursery production of shrimp, Litopenaeus vannamei in tanks
(University of the Philippines Visayas, 2022)
Nursery systems are valuable production tools in shrimp aquaculture and are effective biosecurity facilities for the high-density culture of shrimp postlarvae (PL), resulting in healthy and uniform-sized juveniles. The ...
Evaluation of maturation promoting factor in polychaete (Marphysa sp.) on Indian white prawn, Penaeus indicus female broodstock
(Wiley, 2022-07-15)
Polychaete is considered the best maturation diet for penaeids; however, fluctuating supply and quality warrant detailed studies to understand the specific maturation-promoting factors present in polychaete. Indian white ...
