      Ecology on the feeding of milkfish fry and juveniles, Chanos chanos (Forsskal) in the Philippines 

      P Buri - Memoirs of the Kagoshima University Research Center for the South Pacific, 1980 - Kagoshima University Research Center for the South Pacific
      An extensive ecological survey was conducted in the Philippines to study the feeding of milkfish, Chanos chanos Forsskal. Types of environments examined included coral reefs, lagoons, mangrove and nipa swamps as well as estuarine systems. It was concluded that organic detritus was the basic nutrient for juvenile milkfish and that depositional environments constitute important nursery and feeding grounds for this spcies. The main pathway of energy flow in these coastal ecosystems through the detritus rather than the grazing pathway. The feeding of milkfish was described in terms of habitat structures, stomach content, feeding chronology and feeding behaviour. The result suggests that a better understanding of the function of the ecosystem will help to improve present aquaculture practices as well as guidelines for resource management.

      Identification of postlarvae of the genus Penaeus appearing in shore waters 

      H Motoh & P Buri - Researches on Crustacea, 1981 - Carcinological Society of Japan
      Diagnostic features for the identification of postlarval Penaeus found in the shore waters of the Philippines are described and categorized based on specimens caught from the wild and those hatched and reared in the laboratory.

      Differentiating features for postlarval Penaeus are given which include the relative length of the antennular flagellum, the shape of the rostrum and number of rostral teeth, the antennal spine, the spinules on the dorsal caina of the sixth abdominal segment, and chromatophore patterns.

      Postlarval Penaeus were classified into two species and two groups as follows: (1) P. monodon, larger in size with dense chromatophores, and the long inner antennular flagellum being more than 2.0 times the outer antennular flagellum; (2) P. semisulcatus, the inner flagellum being 1.6 to 2.0 times the outer antennular flagellum, the the absence of chromatophore on the middle portion of the telson and uropods; (3) P. merguiensis group, less pigmented, the inner flagellum being less than 1.6 times the outer flagellum and (4) P. japonicus group, a short rostum, presence of spinules on the dorsal carina of the sixth abdominal segment, and dense chromatophores. The determinations were confirmed by rearing experiments.

      The skull of milkfish, Chanos chanos Forsskal 

      P Buri - SEAFDEC Aquaculture Department Quarterly Research Report, 1979 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The skull of the milkfish, C. chanos, is described so that it may be used as a tool in identifying the effect of artificial propagation in terms of skeletal malformations.
