Arachidonic acid enrichment of rotifers and effects of dietary arachidonic acid on broodstock performance of rabbitfish Siganus guttatus
(Japan International Research Center for Agricultural Sciences, 2006)
Rotifers (Brachionus sp.) were cultured with various combinations of baker’s yeast, Nannochloropsis sp., Culture selco, and DHAPS with or without supplementation of arachidonic acid (triacylglycerol form). Rotifers were ...

Detection of betanodaviruses from different organs of broodstocks and wild juveniles of orange-spotted grouper, Epinephelus coioides
(Japan International Research Center for Agricultural Sciences, 2006)
Aquaculture of grouper including orange-spotted grouper suffers losses from viral nervous necrosis (VNN). This disease usually occurs in larval stage resulting in a high rate of mortality. It is conceivable that vertical ...

Arachidonic acid distribution in mangrove organisms in the Philippines, Malaysia and Japan
(Japan International Research Center for Agricultural Sciences, 2006)
There has been little information on the importance of arachidonic acid (20:4n-6, ArA) in fish and other aquatic animals, although the importance of eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, ...
Incorporation of fatty acids from dietary neutral lipid in eye, brain and muscle of postlarval turbot fed diets with different types of phosphatidylcholine
(Springer, 1998)
Previous results demonstrated the stimulating effect of soybean phosphatidylcholine (PC) on the utilization of dietary neutral lipid in larval and postlarval fish. The present study further investigated the effect of the ...
Comparison of reproductive aspects of the tropical eel Anguilla bicolor (McClelland 1884) in freshwater and estuarine habitats
(Marine Science Department, Diponegoro University, 2023-09-07)
The tropical anguillid eel, Anguilla bicolor McClelland, experiences significant growth up to the adult size in both freshwater and estuarine ecosystems, encountering salinity gradients that may impact their reproduction. ...
Temporal variation in the incidence of seaweed health problems affecting farmed Kappaphycus striatus in relation to environmental conditions in shallow waters
(Springer, 2024-04-18)
A fixed off-bottom Kappaphycus striatus var. sacol farm was monitored for 12 months (June 2019 to May 2020) and the monthly incidence of disease and pests was recorded. Meteorological information in situ, from the nearest ...
The complete mitochondrial genome of freshwater gammarid Gammarus nipponensis (Crustacea: Amphipoda: Gammaridae)
(Taylor and Francis, 2024-04-02)
This study presents the complete mitochondrial genome sequence of Gammarus nipponensis, a freshwater crustacean found in the western regions of Honshu, Shikoku and Kyushu in Japan. The entire genome is 16,429 bp in length, ...
Do adaptation and coping mechanisms to extreme climate events differ by gender? The case of flood-affected households in Dumangas, Iloilo, Philippines
(Asian Fisheries Society, 2014)
This study was conducted to identify and analyse gender-differentiated adaptation measures and coping mechanisms formulated and implemented by households during Typhoon Frank (international name Fengshen), in barangays ...
Sustaining aquaculture by developing human capacity and enhancing opportunities for women
(FAO; NACA, 2012)
People are at the heart of sustaining aquaculture. Development of human capacity and gender, therefore, is an important human dimension. Human capacity development (HCD) was a major thrust of the 2000 Bangkok Declaration ...
Navigating risks and uncertainties: Risk perceptions and risk management strategies in the Philippine seaweed industry
(Elsevier, 2021-04)
The Philippine seaweed industry is affected by multiple but interrelated risks. Farmers mainly encountered environment-related risks (e.g. disease, pest infestations) which, if unmanaged, could result to production failure. ...
