Growth and production of deformed and nondeformed hatchery-bred milkfish (Chanos chanos) in brackishwater ponds
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)
This study evaluated the growth and survival of morphologically deformed and nondeformed hatchery-bred milkfish in brackishwater ponds. It compared the size-frequency distribution of the nondeformed fish with the deformed ...
Growth, maturity and induced spawning of mangrove red snapper, Lutjanus argentimaculatus, broodstock reared in concrete tanks
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)
Mangrove red snapper, Lutjanus argentimaculatus, fry (n=30) were collected in 1993 and reared in concrete tanks. They were fed trash fish every other day initially at 10% to 5%, until they reached three years. They reached ...
Isolation and cDNA cloning of somatolactin in rabbitfish (Siganus guttatus).
(Academic Press, 1999)
We report the isolation and cDNA cloning of somatolactin (SL) from rabbitfish, Siganus guttatus. Rabbitfish SL was isolated from an alkaline extract of the pituitary glands by gel filtration chromatography on Sephadex G-100 ...
Diet development and evaluation for juvenile abalone, Haliotis asinina: protein/energy levels
(Elsevier, 1999)
Juveniles of abalone, Haliotis asinina with mean initial weight and shell length of 0.6±0.03 g and 15±0.07 mm were fed practical diets for 90 days. The practical diets contained graded levels of protein from fish meal, ...
Sargassum studies in Currimao, Ilocos Norte, Northern Philippines I. Seasonal variations in the biomass of Sargassum carpophyllum J. Agardh, Sargassum ilicifolium (Turner) C. Agardh and Sargassum siliquosum J. Agardh (Phaeophyta, Sargassaceae)
(Walter de Gruyter, 1999)
Three species of Sargassum (S. carpophyllum, S. ilicifolium and S. siliquosum were collected each month for a period of one year from the inter- and subtidal zones of Pangil, Currimao, Ilocos Norte, The Philippines. Average ...
Essentiality of phosphorus, magnesium, iron, zinc, and manganese in milkfish diet
(Japanese Society of Fisheries Science, 1999)
Six semi-purified casein based diets were formulated to contain either a complete mineral mixture (control) or mineral premixes from which a specific test mineral was deleted to obtain phosphorus(P)-free, magnesium(Mg)-free, ...
A combined upflow and fluidized sand filter for recirculating systems
(Society of Aquaculture Engineers of the Philippines, Inc., 1999)
The process required and options for water treatment in recirculating systems have been clearly identified. The four most critical processes are: (1) solids removal, to take out fecal waste, uneaten feed, excess bacterial ...
Effect of growth hormone and γ-aminobutyric acid on Brachionus plicatilis (Rotifera) reproduction at low food or high ammonia levels
(Elsevier, 1999)
Growth hormone (GH, 0.0025 and 0.025 I.U. ml<sup>−1</sup>) and γ-aminobutyric acid (GABA, 50 μg ml<sup>−1</sup>) enhance rotifer population growth in batch cultures. In order to further understand the mechanism of their ...
Commercial evaluation of monosex pond culture of the mud crab Scylla species at three stocking densities in the Philippines.
(Elsevier, 1999)
The effects of three levels of stocking density (0.5, 1.5 or 3.0 m<sup>−2</sup>) and monosex culture (male or female) on the growth, apparent feed conversion ratio (FCR), survival, and production of mixed species of mud ...
Interaction between dietary levels of calcium and phosphorus on growth of juvenile shrimp, Penaeus monodon
(Elsevier, 1999)
Information on the dietary phosphorus (P) requirement is essential in the formulation of a cost-effective and low-pollutant feed. Ten isonitrogenous (40% CP) casein–gelatin-based diets containing five graded levels of P ...
