      Llobrera, Alcestis T.; Gacutan, Rogelio Q. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Bacteria in the seawater used in P. monodon hatchery operations were isolated on Bachmann's agar. The total plate counts in 25 isolations ranged from 1.0 - 5.0 x 102 to 5.1 -10.0 x 105 cells per ml. ...
    • Changes induced in the gills of milkfish (Chanos chanos Forsskål) fingerlings after acute exposure to nifurpirinol (Furanace; P-7138) 

      Tamse, Catherine T.; Gacutan, Rogelio Q.; Tamse, Armando F. (Springer Verlag, 1995)
      The need for a chemotherapeutant used specifically for fish disease became increasingly apparent with intensive fish culture practices, and with the possibility of bacterial resistance against drugs used for human and ...
    • Diseases of penaeid shrimps in the Philippines 

      Baticados, Maria Cecilia L.; Cruz-Lacierda, Erlinda R.; de la Cruz, Margarita; Duremdez-Fernandez, Roselyn C.; Gacutan, Rogelio Q.; Lavilla-Pitogo, Celia R.; Lio-po, Gilda D. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1990)

    • Diseases of prawns (pests & diseases of sugpo) 

      Gacutan, Rogelio Q. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
    • 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. ...
    • Effects of furanace on Brachionus 

      Baticados, Ma. Cecilia; Gacutan, Rogelio Q.; Gutierrez, P. J. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Tiger prawn P.monodon) larvae utilize Brachionus a rotifer, as food in the Zoea 3 and mysis stages when they change from an herbivorous to an omnivorous diet. The present work aims to show the effects of furanace on the ...
    • Effects of furanace on the development of larval stages of Penaeus monodon Fabricius 

      Gacutan, Rogelio Q.; Llobrera, Alcestis T.; Baticados, Ma. Cecilia L. (Sea Grant College Program, Texas A&M University, 1979)
      Successful molts and morphological defects in P. monodon zoeae (Z1, Z2, Z3) resulting from a 24-h exposure to 1.0 and 2.0 mg/L furanace in baths of 1.0 and 2.0 mg/L were quantified. Molting ...

      Baticados, Ma. Cecilia L.; Po, Gilda L.; Lavilla, Celia R.; Gacutan, Rogelio Q. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
      Fungal infection of P. monodon larvae is a problem in hatchery operations. The fungus, which attacks the nauplius to postlarval stages and causes up to 100% mortality, has been tentatively identified as belonging to the ...
    • Larval mycosis in Penaeus monodon 

      Baticados, Maria Cecilia L.; Po, G. L.; Lavilla, C. R.; Gacutan, Rogelio Q. (University of the Philippines, Los Baños, 1979)
      A phycomycetous fungus, presumably a Lagenidium, was observed to infect Penaeus monodon larvae. Monitoring of the hatchery in 1976 and 1977 showed that it occurred in 35 out of 51 and 22 out of 37 runs, respectively. So ...
