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 ... -
Induced spawning and larval rearing of grouper (Epinephelus salmoides Maxwell)
(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 ... -
Induction of sex inversion in juvenile grouper, Epinephelus malabaricus, (Bloch and Schneider) by bi-weekly injections of 17 alpha-methyltestosterone
(Society for the Study of Endocrinology, Metabolism and Reproduction, University of Hong Kong, 1989)Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the ... -
The influence of broodstock nutrition on the reproductive performance and egg and larval biochemical composition of the mangrove red snapper, Lutjanus argentimaculatus, for its sustainable aquaculture production
(Japan International Research Center for Agricultural Sciences, 2002) -
Influence of fishing gears on excessive use of fishing grounds in Batan Estuary, Aklan, central Philippines
(Asian Rural Sociology Association, 2010)The excessive fishing activities have led to the depletion of many coastal fisheries resources in most of the countries in Southeast Asia. It is therefore necessary to find out the causal factors of excessive fishing in ... -
Innofloc: Innovative biofloc technology for the nursery production of shrimp, Litopenaeus vannamei in tanks
(University of the Philippines Visayas, 2022)Nursery systems are valuable production tools in shrimp aquaculture and are effective biosecurity facilities for the high-density culture of shrimp postlarvae (PL), resulting in healthy and uniform-sized juveniles. The ... -
Institutional capacity development for sustainable aquaculture and fisheries: Strategic partnership with local institutions
(Terrapub, 2008)Many people living in the rural areas in the Philippines, as in other developing countries in Southeast Asia, depend on aquatic resources for their food and livelihood. For the past two decades, the Aquaculture Department ... -
Integrated farming of broiler chickens with fish and shrimp in brackishwater ponds
(Asian Fisheries Society, 1986)An experiment on the integrated farming of broiler chickens with milkfish (Chanos chanos), tilapia (Oreochromis niloticus) and shrimp (Penaeus indicus) in brackishwater ponds was conducted in 1,000-m2 ponds of ... -
An integrated semi-intensive shrimp and livestock system in the Philippines.
(Asian Fisheries Society, 1986)The development of shrimp (Penaeus monodon) production system integrated with livestock was undertaken at the Sycip Plantation Inc., Negros Orienta, Philippines, as a result of crop diversificstion efforts in the province. ... -
Intensification techniques in the extensive culture of Penaeus monodon
(Asian Fisheries Society, 1986)Traditional shrimp (Penaeus monodon) farming is characterized by low yields, 100-300 kg/ha/yr. To provide farmers with appropriate technology that can immediately improve pond yield with minimal investment, experiments ... -
Interaction of the midgut gland and the ovary in vitellogenesis and consequences for the breeding success: a comparison of unablated and ablated spawners of Penaeus monodon
(European Aquaculture Society, 1989)The midgut glands and ovaries of unablated and ablated females of Penaeus monodon were examined before and after spawning by light and electron microscopy to elucidate the role of the midgut gland during vitellogenesis. ... -
