Economic feasibility of polyculture of tiger shrimp (Penaeus monodon) with Nile tilapia (Oreochromis niloticus) in brackishwater ponds
(Asian Fisheries Society, 1991)
The polyculture of tiger shrimp (Penaeus monodon) with milkfish (Chanos chanos) has been practiced in the Philippines, bit little is known about the possible polyculture of the shrimp with the tilapias in spite of increasing ...
Growth, survival and feed conversion of Nile tilapia fingerlings fed diets containing Bayo-n-ox, a commercial growth promoter
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
A feeding experiment was conducted to determine the effect of a commercial growth promoter, Bayo-n-ox, on Nile tilapia fingerlings (mean initial weight 3.6 g). After 6 weeks, the weight gain of fish given 25 mg Bayo-n-ox/kg ...
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 ...
Growth and reproductive performance of bighead carp (Aristichthys nobilis) reared with or without feeding in floating cages
(Elsevier, 1991)
Bighead carp (10.5 months old) stocked in cages in Laguna de Bay were assigned the following feeding treatments: 1. 40% protein diet, 2. 20% protein diet, and 3. no artificial diet (control), to determine the effects of ...
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 ...
Spermiation response of mature rabbitfish, Siganus guttatus Bloch, to luteinizing hormone-releasing hormone analogue (LHRHa) injection
(Elsevier, 1991)
A method to quantify the spermiation response of mature rabbitfish to hormonal therapy is described. Spermatocrit or packed sperm volume was measured after milt loaded in non-heparinized microhematocrit capillary tubes was ...
Effects of fiber in supplemental feeds on milkfish (Chanos chanos Forsskal) production in brackishwater ponds
(Asian Fisheries Society, 1991)
The study explores the nutritive value of fiber in supplemental feeds for milkfish. The feeding rates were adjusted so that all treatments involved equal protein-N load (6 g·kg<sup>-1</sup> fish/day), and varying ...
Evaluation of different supplemental feeds for milkfish (Chanos chanos) reared in brackishwater ponds
(Elsevier, 1991)
The effects of supplemental feeding on milkfish growth, production, survival, water quality, and economic benefits in brackishwater ponds were evaluated by comparing a rice bran diet, containing 11.3% protein, and two ...
Selective diversification of aquaculture stocks: A proposal for economically sustainable genetic conservation
(NRC Research Press, 1991)
The genetic diversity of aquaculture stocks can be maintained, and their genetic impact on wild stocks minimized, by breeding programmes that deliberately generate genetic diversity. Current animal breeding practices are ...
