      Notable features of fatty acid composition in mangrove fish species 

      Ogata, Hiroshi Y.; Emata, Arnil C.; Garibay, Esteban S. (Japan International Center for Agricultural Sciences, 2003)
      Fatty acid composition was determined in several mangrove and commercial species, mangrove red snapper, rabbitfish, milkfish and striped jack that were sampled in the Central Philippines, with special reference to arachidonic acid (AA) and eicosapentaenoic acid (EPA). As overall traits, the mangrove species had intermediate or high AA and docosahexaenoic acid (DHA) levels and low EPA levels compared to species in the high and temperate northern hemisphere, consequently having high AA/EPA ratios. The present results suggest that AA may be nutritionally much more important in tropical/mangrove species than in cold/cool water species. The information of the present study can be used as a guideline for development of appropriate artificial diets for broodstock and/or larvae in mangrove areas.

      Reproductive performance of the mangrove red snapper, Lutjanus argentimaculatus, fed broodstock diet 

      Emata, Arnil C.; Borlongan, Ilda G.; Garibay, Esteban S.; Ogata, Hiroshi Y. (Japan International Center for Agricultural Sciences, 2003)
      For the mangrove red snapper, there is no information available on effects of broodstock nutrition regarding reproductive performance. This paper, therefore, is an initial study to develop a broodstock diet for the mangrove red snapper in order to ensure consistent production of highest-quality eggs and larvae to support the mass production of fry in the hatchery.
