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 ... -
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 ... -
Carrageenan properties and proximate composition of three morphotypes of Kappaphycus alvarezii Doty (Gigartinales, Rhodophyta) grown at two depths
(Walter de Gruyter, 1995)Three morphotypes (brown, green and red) of Kappaphycus alvarezii grown at two depths were evaluated for carrageenan properties and proximate composition. The green morphotype was significantly different from the brown and ... -
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. ... -
Exploitation of the window-pane shell Placuna placenta in the Philippines
(Elsevier, 1995)The window-pane shell Placuna placenta or 'kapis' has great economic importance in the Philippines. The translucent shell is used in the manufacture of lampshades and other shellcraft items exported to Europe, USA and ... -
Rapid rural appraisal and participatory research in the Philippines
(Oxford University Press, 1995)Rapid Rural Appraisal (RRA) was conducted in the fishing village of Lakaran, in the municipality of Dumangas, Iloilo province to identify the resources, livelihood, problems, opportunities, and socioeconomic condition of ... -
Growth and survival of juvenile tiger shrimp fed diet where fish meal is partially replaced with papaya (Carica papaya L.) or camote (Ipomea batatas Lam.) leaf meal
(Society of Israeli Aquaculture and Marine Biotechnology, 1995)Fish meal is the major protein source in shrimp and fish diets but its continuous use would make it scarce and expensive. There are, however, potential substitutes like soybean or leaf meals. Papaya or camote leaf meals ... -
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 ... -
Resistance to a heavy metal mixture in Oreochromis niloticus progenies from parents chronically exposed to the same metals
(Elsevier, 1995)Adult Oreochromis niloticus were mass spawned in concrete tanks. The one-month old progenies (F1) were exposed for two months to a mixture of 0.01 mg L−1 Hg, 0.1 mg L−1 Cd and 1.0 mg ... -
Effect of stocking density and nutrients on the growth and agar gel of Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1995)The effect of additional nutrients and varying stocking densities (500, 1000, and 2000 g m-2) on the growth and physical properties of Gracilariopsis bailinae was determined. Growth was significantly higher (L ... -
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 ... -
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 ... -
Use of the golden apple snail, cassava, and maize as feeds for the tiger shrimp, Penaeus monodon, in ponds
(Elsevier, 1995)Penaeus monodon stocked in ponds at 8000/ha were fed four types of farm-made feeds starting on day 16 of a 4-month culture period. The feeds were golden apple snail alone or in combination with cooked cassava or maize, or ... -
Growth responses of Spirulina platensis to some physico-chemical factors and the kinetics of phosphorus utilization
(Japanese Society of Fisheries Science, 1995)The growth responses of Spirulina platensis NIES-46, a brackishwater strain originally isolated from Lake Texcoco Mexico, to some physico-chemical factors and nutrients were investigated. The optimum conditions for growth ... -
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 ... -
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 sea turtles captured by coastal fisheries in the northeastern Sulu Sea, Philippines: Documentation, care, and release
(Herpetological Conservation and Biology, 2011)This paper presents the first substantive data on sea turtles in the northeastern Sulu Sea. Working with fishers and government, the Southeast Asian Fisheries Development Center (SEAFDEC FishWorld) documented 109 juvenile ... -
Controlled release of testosterone and estradiol-17 β from biodegradable cylinders
(Controlled Release Society, 1994)A controlled release device for the hormones, testosterone and estradiol-17 β, was developed by coating a melt extruded hormone/poly (ϵ-caprolactone) cylinder with pure polylactide. Since testosterone and estradiol-17β ... -
