    • Tolerance of Penaeus monodon larvae to cupric sulfate added in bath 

      Canto Jr., Jose T. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Copper is used to deter the growth of bacterial, fungal and protozoan disease organism in fishes. Zoeae (Z1), myses (M1) and postlarvae (P1) were exposed to copper sulfate at concentrations ...

    • Effect of furanace on the development of larval stages of Penaeus monodon Fabricius 

      Gacutan, Rogelio Q.; Llobrera, Alcestis T. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Zoea 2 (Z2), Mysis 1 (M1) and Postlarva 1 (P1) of P. monodon artificially spawned in closed-system concrete hatchery tanks were bioassayed for their tolerance to the antibiotic furanace. ...

    • A suctorean parasite of Penaeus monodon larvae 

      Gacutan, Rogelio Q.; Llobrera, Alcestis T.; Santiago, Corazon B.; Gutierrez, P. J.; Lio, Gilda (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      A new disease caused by a suctorean has been observed in tank-spawned and reared P. monodon larvae. Identification of the etiologic agent pointed to Ephelota gemmipara R. Hertwig, a species commonly found to inhabit hydroid ...

    • Identification and culture of common diatoms as possible feed for Penaeus monodon 

      Pimoljinda, Thanom (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Diatoms were collected from Buyuan Bay, and from the hatchery tanks at Tigbauan, to determine the commonly occurring species, the feasibility of culturing these species, and the potential of these selected species as food ...

    • A simple method of tagging prawns 

      Rodriguez, Luis M. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      The recognition of individual animals is crucial to many aspects of research. Prawns (Penaeus monodon) present unique difficulties in this respect since they molt regularly. Thus, almost all tagging and marking methods ...
