Growth response and carcass composition of red tilapia fry fed diets with varying protein levels and protein to energy ratios
(Asian Fisheries Society, 1991)
An 8-week feeding experiment was conducted with red tilapia (Oreochromis ) fry of 0.160 plus or minus 0.035 g initial weight. Twelve diets of 4 protein levels (25, 30, 35 and 40%) and 3 protein to energy (P/E) ratios (111, ...
An artificial diet for larval rabbitfish Siganus guttatus Bloch.
(Asian Fisheries Society. AFS Spec. Publ. 5, 1991)
A 21-day feeding trial was conducted to determine growth, survival and metamorphosis of larval rabbitfish (Siganus guttatus ) fed artificial diets containing approximately 40, 45, 50 and 55% crude protein. Artemia nauplii ...
Biological evaluation of frozen zooplankton as food for milkfish (Chanos chanos) fry
(Verlag Paul Parey, 1991)
Milkfish fry with an average standard length and weight of 13.88 mm and 3.95 mg, respectively, were reared for 30 days using live and frozen Moina macrocopa and Brachionus plicatilis at feeding densities of 10–20 individuals ...
Lipid and fatty acid composition of brackishwater- and freshwater-reared milkfish (Chanos chanos Forskal)
(Elsevier, 1991)
Lipid and fatty acid composition of the various sections of brackishwater- and freshwater-reared milkfish were determined by chromatographic methods. Lipids consisted mainly of the neutral type, which in turn was composed ...
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 ...
Acute toxicity of mercury to Oreochromis niloticus fingerlings
(SEAMEO BIOTROP, 1991)
Fingerlings of Oreochromis niloticus were exposed to the following mercury (as HgCl<sub>2</sub>) concentrations: 0.005, 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 mg l<sup>-1</sup> Hg of water. Hyperactivity and erratic swimming ...
Effects of physico-chemical factors and nutrients on the growth of Spirulina platensis isolated from Lake Kojima, Japan
(The Japanese Society of Fisheries Science, 1991)
The effects of physico-chemical factors and nutrients on the growth responses of Spirulina platensis isolated from Lake Kojima (K-2 strain) were determined. The optimum conditions for growth were the following: ligh intensity ...
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 ...
Economic analysis of an integrated milkfish broodstock and hatchery operation as a public enterprise
(Elsevier, 1991)
The National Bangus (Milkfish) Breeding Program of the Philippines, which was launched by the Philippine government in 1981, had succeeded in spawning milkfish in captivity and in rearing the eggs to fry that were stockable ...
Occurrence and pathology of Penaeus monodon baculovirus infection in hatcheries and ponds in the Philippines
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
Samples from Penaeus monodon hatcheries (2-3 day old larvae or Zoea 1 to 34 day old post larvae or PL<sub>34</sub>) and ponds (15 to 159 days old in the pond) were histologically examined for the presence of eosinophilic ...
