Handling and rearing of hatchery-produced shrimp postlarvae from small-scale hatchery
(South China Sea Fisheries Development and Coordinating Programme, 1982)This paper discusses the handling and rearing of hatchery-produced Penaeus post larvae. The survival and growth of hatchery produced fry and wild caught fry are discussed. -
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 ... -
Hatchery, nursery and grow-out management of the Asian catfish Clarias macrocephalus
(University of the Philippines Aquaculture Society, Inc., 2001)The Asian catfish, Clarias macrocephalus is a native but fast disappearing species in the Philippines. It is locally named as hito to Tagalogs, paltat to Ilocanos, pantat to Cebuanos and Ilongos, and Ito to Pampangueños. ... -
Hematological and histopathological changes in Oreochromis mossambicus after exposure to the molluscicides Aquatic and Brestan
(Department of Fisheries; International Center for Living Aquatic Resources Management, 1988)Duplicate static 96-hour bioassays were conducted to determine the median lethal concentration for Oreochromis mossambicus (LC50) of two organostannous molluscicides, commonly used in fishponds: Aquatin and ... -
The hematological changes in snakehead (Ophicephalus striatus) affected by epizootic ulcerative syndrome
(Asian Fisheries Society, 1994)Selected hematological parameters were studied in snakehead from Laguna de Bay (Philippines) affected with different stages of epizootic ulcerative syndrome (EUS). For comparison, normal (from a non-endemic area) and ... -
Heterogeneity in Philippine milkfish populations
(Asian Fisheries Society, 1990)Twelve milkfish (Chanos chanos ) populations from 6 coastal areas in the Philippines, collected at the fry stage and reared until fingerling size, were analysed for electrophoretic variation at 28 presumptive loci. Seven ... -
Hi-density tank culture of Nile tilapia (Oreochromis niloticus) using lake water with effluent management
(Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA), 2005)Nine concrete tanks (2 x 2 x 1 m) were stocked with tilapia fingerlings (abw = 3.3±0.9 g) and three stocking rates (50 fish/m2, 100/m2, and 150/m2) were tried. The rearing period lasted for ... -
Histopathology of chlorella-feeding in larval milkfish, Chanos chanos
(1986)Unicellular algae, particularly Chlorella, are widely used as starter feeds for marine finfish larvae. However, milk fish larvae when reared on Chlorella sp., suffered morality up to 100% within the first days of feeding ... -
Hormonal changes accompanying sexual maturation in milkfish Chanos chanos Forsskal
(Nagoya University Corporation, 1987)In spite of the economic importance of milkfish to the Southeast Asia, relatively little information is available on its reproductive biology and physiology. Milkfish has a prolonged juvenile phase undergoes first sexual ... -
Hormonal, environmental, and dietary manipulation of milkfish broodstock to enhance egg production
(International Foundation for Science, 1993)The insufficient supply of milkfis fry severely limits the expanion of milkfish aquaculture. While natural spamning and hatchery production of milkfish fry have been attained recently, there is sitll a need to incease egg ... -
Hormone-induced spawning of cultured tropical finfishes
(IFREMER, 1990)Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often administered ... -
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 ... -

Improved hatchery rearing techniques for the Asian catfish, Clarias macrocephalus (Gunther)
(European Aquaculture Society, 1995)The Asian catfish, Clarias macrocephalus, is a popular freshwater foodfish in the Philippines. However, grow-out farming of this species is hampered by the lack of juveniles for stocking. A series of experiments on zooplankton ... -
Improving artisanal fisheries through community-based prawn stock enhancement in a mangrove estuary
(Japan International Research Center for Agricultural Sciences, 2022)Tropical seafood, especially prawns, have always been in high demand with high market prices. Because of this, wild prawn resources are often overfished as indicated by the increasing number of fishers, but with overall ... -
Incidence and causes of mass fish kill in a shallow tropical eutrophic lake (Laguna de Bay, Philippines)
(Shiga Prefectural Government, 2001)Mass fish kills in Laguna de Bay, the largest lake in the Philippines, has been reported as early as in the 1930’s. With the introduction of and development of aquaculture in this lake, considerable attention and concern ... -

Increasing the availability of West African Grey Literature to improve marine fisheries management
(TextRelease, 2021-02)The Fishery Committee for the Eastern Central Atlantic (CECAF) seeks to promote the sustainable utilization of the living marine resources across the Eastern Central Atlantic between Cape Spartel and the Congo river through ... -
Induced maturation in ablated Penaeus notialis and Penaeus schmitti
(Asian Fisheries Society, 1986)Wild Penaeus notialis and P. schmitti were induced to mature by unilateral eyestalk ablation of females in 0.5, 1.6 and 2.0-m super(3) tanks stocked at 9-12 shrimps/m super(3). A total of 71 spawns was obtained from 80 P. ... -
Induced spawning and larval rearing of grouper (Epinephelus salmoides Maxwell)
(Asian Fisheries Society, 1986)Broodfish of grouper (Epinephelus salmoides ) were induced to spawn by hormonal induction. The hormones used for this experiment were HCG + pituitary gland (PG) and LRH-a. The results showed that at dosages of 500 IU HCG ... -
