Fry-to-fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(University of the Philippines at Los Baños, 1982)
Two experiments were conducted to demonstrate the efficiency of phytoplankton as natural feed in fry-to-fingerling production of Tilapia nilotica . In the first experiment, growth and survival rates of fry given a sustained ...
Feed preference of milkfish (Chanos chanos Forsskal) fry given different algal species as natural feed
(Elsevier, 1986)
Acclimated milkfish fry (mean wet weight, 6.0 mg) were fed with unialgal cultures of five species of freshwater algae: Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata and Chlorella ...
Tilapia (T. nilotica) and Azolla (A. pinnata) cage farming in Laguna Lake
(Fisheries Research Society of the Philippines, 1986)
Four batches of Azolla were grown in cages in Laguna lake between 1981 to 1983. Percent increase in weight per day ranged from 35% (Feb. 24 - March 2, 1981) to 5% (May 8 - May 12, 1983.) Best growth was attained during the ...
Size- and weight-dependent cannibalism in hatchery-bred sea bass (Lates calcarifer Bloch)
(Blackwell Publishing, 1991)
The relationship of predator size to maximum prey size, and predator weight to weight of prey consumed among cannibalistic sea bass (Lates calcarifer Bloch) in a hatchery were assessed. Maximum prey size was computed from ...
Induction of sex change in female Epinephelus coioides by social control
(Society of Israeli Aquaculture and Marine Biotechnology, 1997)
Mature female groupers (Epinephelus coioides) of different sizes were stocked in three floating net cages (2 fishes each) and in tanks (2-4 fishes) to induce sex change in the bigger female grouper after isolation from the ...
Multiple gonadal maturation and re-maturation after hormone-induced spawning in bighead carp Aristichthys nobilis Rich.
(San Carlos Publications, University of San Carlos, 1991)
Gonadal maturation and rematuration after hormone-induced spawning in cage-reared female bighead carp Aristichthys nobilis were observed. Percent maturation ranged from 54 to 100% for females and 0 to 40% for males. ...
Hatchery rearing of sea bass Lates calcarifer Bloch
(Science and Technology Information Institute, 1991)
A hatchery rearing scheme for sea bass (Lates calcarifer Bloch) is described. Survival rate from hatching (d0) to harvest (d30) was 34%. Feeding sea bass fry with Chlorella-fed or Selco-enriched instar II Artemia from d19 ...
