Effect of streamer tags on survival and growth of juvenile tiger prawns, Penaeus monodon, under laboratory conditions
(CSIRO Publishing, 1992)
The effects of streamer tags and initial prawn size on survival and growth in 2-month- and 7-month-old pond-reared juveniles of Penaeus monodon Fabricius (11-30 mm carapace length, CL) were assessed under laboratory ...
Effect of dehulling on the nutritive value of some leguminous seeds as protein sources for tiger prawn, Penaeus monodon, juveniles
(Elsevier, 1991)
Feeding experiments were conducted to evaluate the effect of dehulling on the nutritive value of cowpea and rice bean as protein sources for P. monodon juveniles. Diets were prepared by adding legumes to replace 15.6% of ...
Responses of a non-migratory stock of brown trout, Salmo trutta, to ovine growth hormone treatment and seawater exposure
(Elsevier, 1993)
The ability of ovine growth hormone (oGH) to enhance the hypo-osmoregulatory performance of a non-migratory stock of the brown trout (Salmo trutta) was investigated. Three groups of juvenile fish were intraperitoneally ...
Survival and metamorphosis of Penaeus monodon larvae at different salinity levels
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The survival rates of Penaeus monodon nauplii, protozoea and mysis abruptly exposed to salinity of 12, 16, 20, 24, 28, 36, 40 and 50 ppt were determined and compared. Larvae kept at 32 ppt, the spawning or initial rearing ...
Use of gonad color in sexing broodstock of Placuna placenta (Linnaeus, 1758)
(California Malacozoological Society, Inc., 1992)
The window pane oyster, Placuna placenta (Linnaeus, 1758), is a highly valuable bivalve species inhabiting the muddy bottom of coastal bays from the Arabian Sea on the west through the Indian Ocean and Malayan Seas to the ...
Testicular histology and serum steroid hormone profiles in hatchery-bred catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)
Testicular development, gonadosomatic index (GSI), and related steroid hormones (testosterone or T, 11-ketotestosterone or 11-KT, 17α, 20β-dihydroxy-4-pregnen-3-one or DHP) in serum were monitored during an annual reproductive ...
Formation of acid sulfate soil and its implications to brackishwater ponds
(Elsevier, 1995)
Acid sulfate soil formation was observed experimentally during leaching of pyritic soil material. Pyritic soil was saturated with distilled water in glass columns and treated under waterlogged and drained conditions. ...
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 ...
Sargassum Studies in Currimao, Ilocos Norte, Northern Philippines II. Seasonal Variations in Alginate Yield and Viscosity of Sargassum carpophyllum J. Agardh, Sargassum ilicifolium (Turner) C. Agardh and Sargassum siliquosum J. Agardh (Phaeophyta, Sargassaceae)
(Walter de Gruyter, 1999)
The yield (%) and viscosity (cps) of alginate from Sargassum carpophyllum, S. ilicifolium and S. siliquosum collected along the inter- and subtidal zones of Currimao, Ilocos Norte were determined monthly for a period of ...
