Enrichment potential of HUFA-rich thraustochytrid Schizochytrium mangrovei for the rotifer Brachionus plicatilis
(Elsevier, 2009)
An enrichment experiment was performed to evaluate the changes in lipid and essential fatty acid contents of the rotifer Brachionus plicatilis fed with freeze-dried cells of tropical thraustochytrid Schizochytrium mangrovei ...
Developing a self-sufficient Philippine milkfish industry through value chain analysis
(Elsevier, 2021-02-15)
The Philippine milkfish industry has been dependent on the importation of juveniles for grow-out ever since the decline of wild fry catch and with inadequate supply from local hatcheries. However, self-sufficiency is ...

A survey was conducted to obtain information on the fish culture practices of the fish farmers in Laguna de Bay, Philippines. Fish farms vary greatly in size. Nile tilapia and bighead carp are the two fish species cultured ...
Ice-Ice disease: An environmentally and microbiologically driven syndrome in tropical seaweed aquaculture
(Wiley, 2022-01)
Seaweeds account for nearly 30% of global aquaculture production by volume, and their cultivation provides important opportunities for employment and wealth generation, particularly in rural coastal communities. Eucheumatoids ...
Towards increased production of milkfish fry in the Philippines: SEAFDEC/AQD technology through the lens
(Secretariat, Southeast Asian Fisheries Development Center, 2021)
Although the Philippines has a long coastline and is surrounded by rich waters, its capture fisheries subsector is just second to aquaculture which is the main driver for growth in the fish production industry of the ...

In vitro and in vivo evaluation of the efficacies of commercial probiotics and disinfectant against acute hepatopancreatic necrosis disease and luminescent vibriosis in Litopenaeus vannamei
(Elsevier, 2024-05)
The bioactivities of two commercially available probiotics and one chemical disinfectant were tested against strains of Vibrio parahaemolyticus (VP<sub>AHPND</sub>) and V. harveyi. This study aimed to determine shrimp pathogenic Vibrios' in vitro and in vivo sensitivities to commercial probiotics and a chemical disinfectant. The probiotics and disinfectant were tested first in vitro, followed by the in vivo trials. Results showed that upon administration of probiotics either through diet or adding into the tank water, the survivability of shrimp was increased during challenge with VP<sub>AHPND</sub> and V. harveyi. Also, the disinfectant was tested against the same pathogens and showed positive bactericidal effects at 2500 ppm and 5000 ppm. The present findings suggest that adding probiotics to the rearing water or the shrimp feeds effectively prevents infection by lowering the load of pathogenic bacteria. In comparison, the effectiveness of the disinfectant (PUR) depends on its appropriate concentration and timing of application. It is not only limited to rearing water but is also applicable for decontaminating pond liners, tanks, and other paraphernalia....
