Improved survival and growth of silver therapon Leiopotherapon plumbeus early juveniles through co‐feeding with Artemia and commercial feeds
(Wiley, 2021-12)
This study examined the effects of co-feeding Artemia and commercial feeds on survival, growth and fatty acid composition of silver therapon Leiopotherapon plumbeus early juveniles. Triplicate groups of 36 days post hatch ...
Distribution of the tropical seaweed crops Eucheuma spp. and Kappaphycus spp. inside and outside of their native range
(Taylor and Francis, 2021)
Seaweed aquaculture is a fast-growing industry worldwide and has the potential to change the seascape of coastal regions, including the movement of species outside their native range. Two of the crops with the highest ...
Utilization of sodium bicarbonate as anesthetic during routine husbandry activities in ornamental fish
(IOP Publishing, 2021-11)
The tropical ornamental fish industry requires the stock to be reared in captivity before being sold; thus, exposing them to various handling- and transport-related stressors. A number of commercially available anesthetics ...
Seasonal population dynamics of Lepeophtheirus spinifer and Neobenedenia sp. coinfecting snubnose pompano (Trachinotus blochii) breeders in marine cages in the Philippines
(Elsevier, 2022)
Studies on the biology and ecology of sea lice are lacking in tropical regions such as in Southeast Asia where finfish cage farming has grown dramatically in the past decades. This study investigated the seasonal population ...
Microbiological quality and heavy metal concentrations in slipper oyster (Crassostrea iredalei) cultured in major growing areas in Capiz Province, Western Visayas, Philippines: Compliance with international shellfish safety and sanitation standards
(International Association for Food Protection, 2022)
The increasing demand for slipper oyster (Crassostrea iredalei) has propelled farmers to expand oyster cultivation areas in the Philippines, chiefly for local consumption and feasibly for export overseas. As filter feeders, oysters can accumulate pathogens from the surrounding waters, and these pathogens can cause foodborne diseases in consumers. Therefore, oyster farming areas must be monitored for microbiological quality and heavy metal concentrations. In the present study, the microbiological quality of oysters and their growing waters in the major oyster farming areas of the Cogon and Palina Rivers and Cabugao Bay (in Roxas City and the Municipality of Ivisan, respectively, Capiz Province, Western Visayas, Philippines) were examined monthly during the wet (May to October) and dry (November to April) seasons over 12 months. Regardless of the sampling period, high levels of fecal coliforms in the water and Escherichia coli in oysters were found, clearly illustrating that these oyster growing areas would meet only the class B standard under the European Union classification system and would be considered “prohibited” for growing oysters under the U.S. classification system. Although Salmonella was occasionally detected in oysters, Vibrio cholerae was not detected and Vibrio parahaemolyticus was within acceptable limits. The heavy metal concentrations in oyster meat were also determined during the wet (July) and dry (March) seasons. Zinc and copper were the most abundant metals detected, and concentrations of lead, cadmium, mercury, and chromium were below the regulatory limits set by the European Union and the U.S. Food and Drug Administration. These oyster culture areas should be rehabilitated immediately to improve the microbiological quality of the oysters. Oysters harvested from these sites must be depurated or relayed to ensure quality and safety....
Rearing silver therapon Leiopotherapon plumbeus (Teleostei: Terapontidae) larvae using euryhaline rotifers as starter food
(College of Agriculture and Food Science, University of the Philippines Los Baños, 2021-12)
The silver therapon Leiopotherapon plumbeus is an important but dwindling freshwater food commodity in Philippine freshwater habitats. The influence of feeding regimes on growth performance and survival of first-feeding ...
Phytochemical composition antioxidant and antibacterial activity of the Philippine marine green alga (Ulva pertusa)
(Springer, 2022-03)
The phytochemical constituents, total phenolic and flavonoid contents, antioxidant and antimicrobial activities of the ethanolic extract of the marine green alga Ulva pertusa collected from floating fish net cages off the ...
Effects of exogenous hormones and broodstock age on the spawning response of captive silver therapon Leiopotherapon plumbeus
(Wiley, 2022)
Evaluation of appropriate hormone and ideal broodstock age for optimal breeding efficiency may ensure the production of good quality eggs and larvae in the hatchery. In this study, the spawning response of captive silver ...
The influence of monosex rearing on gonad maturation and reproductive behavior of Indian white prawn, Penaeus indicus broodstock
(Elsevier, 2022-02)
Monosex culture was proven to be an effective rearing method for grow-out, but in a closed-cycle hatchery, males and females are usually reared communally in tanks until maturation. This study determined the effect of ...
Development of a giant grouper Luteinizing Hormone (LH) Enzyme-Linked Immunosorbent Assay (ELISA) and its use towards understanding sexual development in grouper
(Elsevier, 2020-07-13)
A recombinant giant grouper Luteinizing Hormone (LH) consisting of tethered beta and alpha subunits was produced in a yeast expression system. The giant grouper LH β-subunit was also produced and administered to rabbits ...
