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 ...
Analysing the diel feeding patterns and daily ration of Nile tilapia, Oreochromis niloticus (L.), in Laguna de Bay, Philippines
(Wiley-Blackwell, 1999)
Cage cultured Nile tilapia, Oreochromis niloticus, were sampled at a commercial set-up on two occasions in 1995 in Laguna de Bay, Philippines, each time over a 24 h cycle. The stomach content weights were averaged for each ...
Establishment of cell lines from catfish (Clarias batrachus) and snakeheads (Ophicephalus striatus)
(Asian Fisheries Society, 1999)
Primary cell cultures from catfish (Clarias batrachus) and snakeheads (Ophicephalus striatus) were prepared from whole fry and fingerling organ tissues of the brain, fins, gonad, heart, kidney, liver, skin and spleen. Four ...
Density dependent growth of the tropical abalone Haliotis asinina in cage culture
(Elsevier, 1999)
The effects of different stocking densities on the growth, feed conversion ratio and survival of two size groups of the tropical abalone Haliotis asinina were determined. Three culture trials were conducted in net cages ...
Feed ration for different sizes of wild and hatchery-bred milkfish (Chanos chanos Forsskal)
(Wiley-Blackwell, 1999)
Intensified production of fish involves stocking at high densities and the use of artificial feeds. These practices result in eutrophication and environmental degradation mainly because of feed wastage and fish excreta. ...
Butylated hydroxytoluene: its effect on the quality of shrimp diet stored at various temperatures and on growth and survival of Penaeus monodon juveniles
(Elsevier, 1999)
Shrimp diets with and without the antioxidant, butylated hydroxytoluene (BHT) were stored at 10°, 20°, 28°–30°, and 40°C for 10 weeks. To monitor lipolysis and lipid oxidation, free fatty acid (FFA) content, peroxide values ...
Quantitative dietary requirements of postlarval tiger shrimp, Penaeus monodon, for histidine, isoleucine, leucine, phenylalanine and tryptophan
(Elsevier, 1999)
The quantitative requirements of postlarvae Penaeus monodon for essential amino acids were determined through a series of feeding experiments. Test diets contained casein–gelatin as natural proteins supplemented with ...
Protected areas for biodiversity conservation and environment education in the Philippines
(Science and Technology Information Institute, 1999)
The Philippines holds the distinction of having enormous biodiversity with the highest density of endemic species but has the problem of very fast decline in old-growth forests and the highest number of endangered mammal ...
