The plight of older women in a fishing village: The women fish traders of Bugtong Bato, Aklan, central Philippines
(ICLARM, 2001)The changing nature of the fisheries in Bugtong Bato, a small fishing community in Central Philippines has also changed the role of women, particularly of older women, in the community. Until the 1980s, fishing used mainly ... -
Recent developments in freshwater and marine cage aquaculture in the Philippines
(Asian Fisheries Society; World Aquaculture Society - Southeast Asian Chapter, 2000)Fish production from freshwater cages and pens, and marine cages and pens constitute 19% of the total foodfish produced from aquaculture in the Philippines. In 1998, production from freshwater cages and pens contributed ... -
Restocking of windowpane shell, Placuna placenta in a depleted bed off Tigbauan, Iloilo, the Philippines
(Phuket Marine Biological Center, 2000)The Tigbauan coast, Iloilo, the Philippines, has been depleted of the natural population of the windowpane shell, Placuna placenta Linnaeus, 1758, since the early 1980's. To support the declining P. placenta industry of ... -
Illuminated-cage nursery of the Asian sea bass, Lates calcarifer Bloch, (Centropomidae): effects of initial body size and stocking density
(Asian Fisheries Society; World Aquaculture Society - Southeast Asian Chapter, 2000)This study was conducted to determine the appropriate initial body size and the corresponding stocking density of sea bass, Lates calcarifer, during nursery rearing in illuminated cages. Hatchery-produced sea bass fry of ... -
Spontaneous spawning, fecundity and spawning periodicity in the donkey's ear abalone Haliotis asinina Linnaeus 1758
(Phuket Marine Biological Center; Phuket Marine Biological Center Special Publication 21(1), 2000)Spontaneous group spawning was monitored in wild-caught (WC) and hatchery-bred (HB) abalone broodstock (Haliotis asinina) held in duplicate tanks at 1:3 (male: female) ratio from June 1997 to January 1999. Abalone ... -
Postlarvae density and photoperiod effects on the settlement and metamorphosis of the donkey's ear abalone, Haliotis asinina Linne, 1758
(Phuket Marine Biological Center, 2000)The effects of photoperiod and density of postlarvae on settlement and metamorphosis of the native abalone, Haliotis asinina were determined in two separate experiments. Abalone larvae were hatched from spontaneously ... -
Hatchery management for the window-pane shell, Placuna placenta Linnaeus, 1758
(Phuket Marine Biological Center, 2000)To relieve pressure on wild stock population, a hatchery technique for the window-pane shell, Placuna placenta Linnaeus has to be developed. A study was conducted to determine the suitable algal diet for P. placenta during ... -
Development of hatchery techniques for the mud crab Scylla serrata (Forskål): Comparison of feeding schemes
(Australian Centre for International Agricultural Research, 1999)Scylla serrata larvae were reared in 3 L plastic containers and fed various amounts of artificial diets (AD) with or without natural food (NF: Brachionus rotundiformis and newly-hatched Artemia). The amounts of AD fed alone ... -
Monosex culture of the mud crab Scylla serrata at three stocking densities with Gracilaria as crab shelter
(Australian Centre for International Agricultural Research, 1999)The effects of three levels of stocking density (0.5, 1.5 or 3.0/m2) and monosex culture (male or female) on the growth, survival and production of Scylla serrata were investigated. Juvenile crabs were stocked in 150 m2 ... -
Larval survival and megalopa production of Scylla sp. at different salinities
(Australian Centre for International Agricultural Research, 1999)Salinity tolerance was determined for each zoeal stage of Scylla sp. Larvae from ablated pond-grown females were abruptly transferred to salinities of 12, 16, 20, 24, 28 and 32 ppt. Spawning salinity or previous rearing ... -
Will microbial manipulation sustain the ecological balance in shrimp (Penaeus monodon) hatcheries?
(National Center for Genetic Engineering and Biotechnology, 1998)A shift in preferred methods employed to contain bacterial diseases in the hatchery phase of shrimp culture has resulted largely from the unsuccessful control by and deleterious effects of chemotherapy. Manipulation of ... -
Shrimp diseases in the Philippines: a historical perspective of research, training and development.
(Department of Marine Biology, Ocean University of Qingdao, 1998)Pioneering research on shrimp diseases in the Philippines was spearheaded at the Aquaculture Department of the Southeast Asian Fisheries Development Center at Tigbauan, Iloilo in 1975. Investigations initially covered ... -
Reproductive performance of pond-sourced Scylla serrata fed various broodstock diets
(Australian Centre for International Agricultural Research, 1999)Feeding experiments were conducted to determine the effect of diet on reproduction of pond-sourced unablated and ablated Scylla serrrata broodstock. Broodstock were fed either natural food (T1) consisting of mussel, squid, ... -
Urease activity in soybean meal: effect on its nutritional quality and on growth and survival of Penaeus monodon juveniles.
(International Foundation for Science, 1998)Based on the results of a survey conducted on the urease activity (UA) in commercial shrimp feed containing soybean meal (SBM) (0.00-29. 70 ppm UA), a study was carried out to determine the effects of different heat ... -
Zooplankton distribution during winter using Two-Way Indicator Species Analysis (TWINSPAN) and Canonical Correspondence Analysis (CANOCO).
(1998)Spatial distribution and community structure of zooplankton species and its relationships with the environmental parameters (temperature, salinity, and turbidity and phytoplankton distribution) in some sandbanks of the ... -
Protein and dry matter digestibility of feedstuffs in complete diets for Penaeus monodon
(Asian Fisheries Society, 1997)The digestibilities of animal and plant protein sources were determined for P. monodon (30 ~ 40 g wet weight). Protein sources were incorporated in complete diets containing the indicator, chromic oxide at 1.8%. Casein, ... -
Optimum stocking density and tank size for larval rearing of the grouper, Epinephelus coioides
(Asian Fisheries Society, 1997)The effect of stocking of stocking density and tank size on early growth and survival of grouper, Epinephelus coioides (=suillus) larvae were determined. In one experiment, larvae were stocked in 500L tanks at densities ... -
Comparative strategies in community-based mangrove rehabilitation programs in the Philippines
(United Nations Educational Scientific and Cultural Organisation; Japanese Man and the Biosphere National Committee; Mangrove Ecosystem Research Centre, 1997)Philippine Mangroves have decreased from around 500,000 ha at the turn of the century to 132,000 ha in 1990. Given the varied and important socioeconomic and ecological functions of mangroves including harvest of forestry ... -
A strategy for sustainable mariculture
(Malacca Straits Research and Development Centre (MASDEC), Universiti Putra Malaysia, 2002)From merely growing shellfish and macroalgae along the freinges of the sea, man is naw growing marine fish in cages thus expanding the range of mariculture. While the farming of shellfish may have its own set of problems ... -
