Diel activity patterns in Metapenaeus and Penaeus juveniles
(Springer Verlag, 1995)
Small (5–10.9 mm carapace length), medium (11–15.9 mm), and large (16–20.9 mm) juveniles of Metapenaeus anchistus, Metapenaeus sp., Penaeus monodon and P. merguiensis were stocked individually in glass tanks provided with ...
Spawning and larval development of a tropical abalone Haliotis asinina (Linne)
(Science and Technology Information Institute, 1995)
Dessication, thermal shock, ultraviolet-irradiated seawater, and hydrogen peroxide, singly or in combination, failed to induce the tropical abalone, Haliotis asinina to spawn viable number of eggs or sperm. However, natural ...
Economic analysis of prawn (Penaeus monodon) culture in the Philippines, I. Hatchery operations
(Asian Fisheries Society, 1995)
High prices of prawn (Penaeus monodon) fry, profitability of hatchery operations, and a low cost hatchery design introduced by the Southeast Asian Fisheries Development Center attracted millions of dollars of investments ...
The effect of tank color and rotifer density on rotifer ingestion, growth and survival of milkfish (Chanos chanos) larvae
(San Carlos Publications, University of San Carlos, 1995)
The effect of tank color on rotifer ingestion, early growth and survival of milkfish larvae was assessed. The larvae were stocked at 30/L in 200-L fiberglass tanks coated black or unpainted (tan). Larvae were fed rotifers ...
Mangroves and brackishwater pond culture in the Philippines
(Springer Verlag, 1995)
Around 50% of mangrove loss in the Philippines can be traced to brackishwater pond construction. The decrease in mangroves from 450 000 ha in 1920 to 132 500 ha in 1990 has been accompanied by expansion of culture ponds ...
Cortisol stimulates the size and number of mitochondrion-rich cells in the yolk-sac membrane of embryos and larvae of tilapia (Oreochromis mossambicus) in vitro and in vivo
(John Wiley and Sons, 1995)
The effect of cortisol and thyroid hormones on the activity of mitochondrion-rich (MR) cells in the yolk-sac membrane of tilapia (Oreochromis mossambicus) embryos and larvae was investigated. MR cells were identified by ...
Effect of dietary protein to energy ratios on growth, survival, and body composition of juvenile Asian seabass, Lates calcarifer
(Elsevier, 1995)
The optimum protein-to-energy (P/E) ratio for juvenile sea bass (body weight, 1.34 ± 0.01 g) was determined using practical diets in a 3 × 3 factorial experiment. Three protein levels (35, 42.5 or 50%) and three lipid ...
Foregut evacuation, return of appetite and gastric fluid secretion in the tropical freshwater crayfish, Cherax quadricarinatus
(Elsevier, 1995)
The effects of animal size and feeding frequency on the foregut evacuation rates by Cherax quadricarinatus, that fed voluntarily on pellet food (meal size eaten, 1.3–1.4% body weight), were determined using a modified ...
Milt-egg ratio in artificial fertilization of the Asian freshwater catfish, Clarias macrocephalus, injected salmon gonadotropin-releasing hormone analogue and domperidone
(Cambridge University Press, 1995)
The author deals with the catfish Clarias macrocephalus which are artificially fertilized by inducing females to spawn using various hormones. This paper investigates the effect of Ovaprim on milt production and fertilizing ...
Effect of a diet lacking in vitamin and mineral supplements on growth and survival of Penaeus monodon juveniles in a modified extensive culture system
(Elsevier, 1995)
Penaeus monodon postlarvae (mean weight 6 mg) were reared in 330 m<sup>2</sup> earthen ponds for 120 days at a stocking density of 7.5 m<sup>−2</sup>, following a modified extensive culture system where natural food organisms ...
