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 ... -
Marine-fish mangrove aquaculture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2000)Aquaculture has often been blamed by environmental lobby groups as one of the main causes of mangrove destruction. In the Philippines, large areas of mangroves were converted through the years into fish and shrimp ponds. There ... -
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, ... -
Tropical shrimp farming and its sustainability
(Academic Press, 1998)In December 1996, the Supreme Court of India ordered the closure of all semi-intensive and intensive shrimp farms within 500 m of the high tide line, banned shrimp farms from all public lands, and required farms that closed ... -
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 ... -
Historical and current trends in milkfish farming in the Philippines
(Academic Press, 1998)This chapter focuses on the historical and current practices of milkfish farming in the Philippines. The Philippines ranks among the top 12 largest fish producers in the world and the milkfish, Chanos chanos, is the official ... -
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 ... -
Egg quality of grouper Epinephelus coioides fed different fatty acid sources
(American Fisheries Society, Physiology Section, 1996)Quality of eggs spawned by Epinephelus coioides fed fish by catch (control). Cod liver oil-enriched fish by catch (TFC), and commercial HUFA A-enriched fish by catch (TFS) was monitored. Monthly egg production, spawning ... -
Viability of milkfish eggs and larvae after simulated and actual transport
(Physiology Section, American Fisheries Society, 1996)The viability of milkfish eggs and larvae after simulated and actual transport was investigated. Naturally-spawned milkfish eggs were collected and subjected to simulated or actual transport at early cleavage stage (stage ... -
The status of seed production of grouper and other coral reef fishes in the Philippines
(Institute for Development Studies, 1999)Initial work on seed production of grouper in the Philippines was first reported in 1986. Most of the work has been undertaken by the SEAFDEC Aquaculture Department (SEAFDEC/AQD), which concentrated on Epinephelus coioides. ... -
Management of fish health in broodstock and larvae of milkfish, sea bass and grouper
(The Oceanic Institute, 1996)Historically, reports on the occurrence of disease problems in milkfish, seabass and grouper were mainly on the isolation and identification of etiological agents. Studies on the tolereance of fish to chemotherapeutants ... -
Shrimp health research in the Asia-Pacific: present status and future directives
(Food and Agriculture Organization of the United Nations, 1996)Shrimp harvests from intensive aquaculture have recently declined in areas which have been productive for many years. Because the most convenient, although not necessarily factual, explanation for these crop failures has ... -
Gracilaria studies at SEAFDEC/AQD
(Network of Aquaculture Centres in Asia-Pacific, 1996)Research in seaweed from 1988–1994 focused on the agar producing Gracilaria. Studies in the following areas were also conducted: inventory of the seaweed resources; production ecology; farming systems; and agar characterisation. ... -
