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 ... -
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 ... -
Development of hatchery techniques for the mud crab Scylla serrata (Forskål): Comparison of feeding schemes
Quinitio, Emilia T.
; ; (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 ... -
Larval survival and megalopa production of Scylla sp. at different salinities
; Quinitio, Emilia T. (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 ... -
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 ... -
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
; Quinitio, Emilia T. (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, ... -
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 ... -
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 ... -
Comparative strategies in community-based mangrove rehabilitation programs in the Philippines
Primavera, Jurgenne; (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 ... -
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 ... -
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, ... -
Viability of milkfish eggs and larvae after simulated and actual transport
(American Fisheries Society, Physiology Section, 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 ... -
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 ... -
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 ... -
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 ... -
