      Baluyut, Elvira A. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      This study was made as an attempt to investigate some of the ecological aspects of the freshwater snail Idiopoma angularis Muller in a modern framework of energy flow and mathematical models. It offers the first investigation ...

    • The biology and control of Caligus sp., an ectoparasite of the adult milkfish Chanos chanos Forskal 

      Laviña, Einstein M. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      One unidentified species of copepod belonging to the genus Caligus of the family Caligidae was found to infest the adult milkfish broodstock. To control the parasites infesting the adult milkfish, tests were made using the ...

    • Biology and farming of the green mussel Mytilus smaragdinus 

      Yap, Wilfredo G.; Orano, Celia; Tabbu, Marlo (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Biological investigations were carried out in Sapian Bay, Capiz from November 1975 to December 1976 with samplings conducted fortnightly. Histological studies on the gonad reveal a high percentage of ripe and spent females ...

    • Catch composition of penaeid prawns caught with fish corrals at Batan Bay, Philippines 

      Motoh, Hiroshi; Solis, Noel; Caligdong, Edna (Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)

    • Changes in length and weight of milkfish fry preserved in formalin 

      Kumagai, Shigeru; Castillo, Nelson (Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
      Fry shrank immediately after they were preserved in formalin, but from the second week onwards shrinkage was almost nil. Fry in freshwater formalin solutions shrunk less than those in seawater formalin solutions. It is ...

    • A comparative study of various extenders of milkfish, Chanos chanos (Forsskal) sperm preservation 

      Hara, Shiro; Canto Jr., Jose T.; Almendras, Jesus M. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
      Four chemical extenders in 7 different concentrations (potassium chloride, sodium chloride, glucose, sodium citrate, Ringer s solution, cow serum and milkfish (Chanos chanos) serum) were compared in the preservation of ...

    • A comparison between the catching efficiency of two milkfish fry collecting gears and their respective modifications 

      Quinitio, Gerald F.; Kawamura, G. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
      An experiment was conducted along the shore of Culasi, Antique in Panay to compare the milkfry (Chanos chanos) catching efficiency of the ordinary fry seine against its innovation and the ordinary sweeper against its 2 ...
