      Developmental and ecological stages in the life history of milkfish Chanos chanos (F.) 

      P Buri, VC Bañada & AT Triño - Fisheries Research Journal of the Philippines, 1981 - Fisheries Research Society of the Philippines
      Seven stages in the life history of milkfish Chanos chanos are suggested: embryonic, yolksac larval, larval, postlarval, juvenile, sub-adult and adult stages. These were based on morphological differences and on their particular ecological requirements. The latter include: behavioral pattern, food and feeding habits, and habitat requirements. Throughout the life cycle of milkfish the stronger driving force with determines particular behavioral strategies can be attributed to the evolutionary response of the organism of food distribution (availability) followed by predation pressure.

      Early postmysis stages of the giant tiger prawn, Penaeus monodon Fabricius 

      H Motoh & P Buri - Researches on Crustacea, 1980 - Carcinological Society of Japan
      The morphological development of the early postmysis stages of the giant tiger prawn, Penaeus monodon are described and illustrated using laboratory-reared specimens and wild ones.

      The first 3 or 4 substages are termed "megalopa" owing to the incomplete branchial formula of the mouth parts, their pelagic or planktonic behavior and their somewhat narrower body. At the 4th or 5th substage, the branchial formula is completed, their behavior is more or less epibenthic, the chromatophores are densely distributed from the tip of the antennular flagella through the ventral side of the abdomen to the tip of the telson. At the beginning of the 7th substage, the chromatophores are distributed over almost the whole body. Thus from the 4th or 5th substage onwards they may be termed juveniles.

      The main characteristics development are as follows : 1) The cempletion of the rostral spine formula appears in the 7th or 8th substage showing 7 dorsal and 3 ventral spines. 2) The endopod of the 1st maxilliped develops again at the 7th substage, although it degenerates with every molt prior to the 7th. 3) From the 1st substage, the distal 3 segments of the endopod of the 2nd maxilliped are bent sharply inwards.

      Identification of the postlarval Penaeus (Crustacea, Decapoda, Penaeidae) appearing along shore waters 

      H Motoh & P Buri - SEAFDEC Aquaculture Department Quarterly Research Report, 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Diagnostic characters for the identification of postlarval Penaeus appearing along the coastal waters of the Philippines are reviewed and categorized, based on materials from the wild and laboratory. Presently there are 7 adult known species belonging to the genus Penaeus around Panay Island and its adjacent waters, namely: P. monodon, P. semisulcatus, P. merguiensis, P. indicus, P. japonicus , P. canaliculatus, and P. latisulcatus.

      Studies on the penaeoid prawns of the Philippines 

      H Motoh & P Buri - Researches on Crustacea, 1984 - Carcinological Society of Japan
      Thirty-five species of penaeoid prawns, representing 9 genera in 3 families, have been found over a period of 5 years from 1976 to 1980 in the Philippine waters. Of these, 15 species have been recorded for the first time from the country.

      Keys for the identification of genera and species, and descriptions as well as illustrations of 35 species except for the illustration of Metapenaeus moyebi are provided.

      Twelve species out of the 35 species are commercially important. They are Metapenaeus anchistus, M. dalli as well as M. moyebi, M. ensis, Penaeus indicus, P. japonicus, P. latisulcatus, P. merguiensis, P. monodon, P. semisulcatus, Solenocera alticarinata, and S. melantho, of which P. monodon is the greatest because of its large size, abundant occurence of the fry and easier cultivation in the pond, and furthermore, other five Penaeus species are of great potential for an aquaculture in brackishwater fishponds.
