Sensitivity of grouper Epinephelus coioides eggs to handling stress at different stages of embryonic development
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)The sensitivity of grouper Epinephelus coioides eggs to handling stress at different stages of embryonic development was investigated. Naturally-spawned grouper eggs in floating net cages were collected and handled at the ... -
Butylated hydroxytoluene: its effect on the quality of shrimp diet stored at various temperatures and on growth and survival of Penaeus monodon juveniles
(Elsevier, 1999)Shrimp diets with and without the antioxidant, butylated hydroxytoluene (BHT) were stored at 10°, 20°, 28°–30°, and 40°C for 10 weeks. To monitor lipolysis and lipid oxidation, free fatty acid (FFA) content, peroxide values ... -
Ecological considerations in milkfish farming in marine pens and cages in the Philippines
(University of the Philippines in the Visayas, 1998)Milkfish farming in the Philippines has a long history and great importance, being widely regarded as the way to domestic food security. But the industry has faced new challenges in the past decade, with the advent of many ... -
Milkfish (Chanos chanos) production and water quality in brackishwater ponds at different feeding levels and frequencies
(Wiley-Blackwell, 1998)This study evaluated the effects of different feeding levels and frequencies on milkfish (Chanos chanos) growth, feed efficiency, and water quality in brackish water ponds. Milkfish juveniles (average weight, 1 g) were ... -
Women and the question of sustainable development in a Philippine fishing village
(Taylor & Francis, 1998)This paper presents a case study of time use and contribution to the household income of men, women, and children in 12 households in a fishing village in Panay Island, central Philippines. The study highlights the ... -
Morphometric relationship of length and weight of giant tiger prawn Penaeus monodon according to life stage, sex and source
(Elsevier, 1998)Regression analysis was performed on length–weight and length–length measurements of Penaeus monodon (n=3270 individuals) including carapace length, body length, total length and body (wet) weight of different life stages ... -
Mangroves as nurseries: Shrimp populations in mangrove and non-mangrove habitats
(Elsevier, 1998)A total of 4845 penaeids belonging to nine species—Metapenaeus anchistus, M. ensis, M. moyebi, M. philippinensis, Penaeus merguiensis, P. monodon, P. semisulcatus, P. latisulcatus and Metapenaeopsis palmensis—were collected ... -
Nature's subsidies to shrimp and salmon farming
(American Association for the Advancement of Science, 1998)Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ... -
Requirements of juvenile marine shrimp, Penaeus monodon (Fabricius) for lysine and arginine
(Elsevier, 1998)Feeding experiments were conducted using amino acid test diets to determine the dietary requirements of juvenile Penaeus monodon for lysine and arginine. Two sets of the test diets were prepared. The natural protein was ... -
Experimental induction of lesions in snakeheads (Ophicephalus striatus) and catfish (Clarias batrachus) with Aeromonas hydrophila, Aquaspirillum sp., Pseudomonas sp. and Streptococcus sp.
(Wiley-Blackwell, 1998)Isolates of Aquaspirilluni sp., Pseudomonas sp., and Streptococcus sp. recovered from epizootic ulcerative syndrome (EUS)-affected snakeheads (Ophicephalus striatus) in Thailand as well as an isolate of Aeromonas hydrophila ... -
Bacterial flora in the hepatopancreas of pond-reared Penaeus monodon juveniles with luminous vibriosis
(Elsevier, 1998)Quantification and characterization of bacterial flora in the hepatopancreas (hp) of pond-reared Penaeus monodon juveniles affected with luminous bacteria were conducted in 1994 and 1995. Shrimp samples were taken from 23 ... -
Bacterial diseases in shrimp (Penaeus monodon) culture in the Philippines
(Japanese Society of Fish Pathology, 1998)The hatchery system for Penaeus monodon evolved from the Japanese community culture system to the modified Galveston method and this shift in culture technique triggered the outbreak of diseases due to opportunistic bacteria. ... -
Mortalities of pond-cultured juvenile shrimp, Penaeus monodon, associated with dominance of luminescent vibrios in the rearing environment
(Elsevier, 1998)Severe mortalities due to luminescent vibrios occurred in pond-cultured Penaeus monodon juveniles particularly in the first 45 days of culture. Luminescent vibriosis epizootics led to reduced shrimp production due to ... -
Assessment of the seaweed-seagrass resource of Mararison Island, Culasi, Antique, Philippines
(Japanese Society of Phycology, 1998)A bimonthly sampling of the seaweed-seagrass resource of Mararison Island, Culasi Antique, was undertaken over 1 year to assess the species composition, similarity of taxa, and biomass (dry weight [d.w.] g m−2) ... -
Sensitivity of fertilized milkfish (Chanos chanos Forsskal) eggs to mechanical shock and simulated transport
(Elsevier, 1998)Naturally-spawned milkfish eggs are routinely subjected to physical manipulation during collection and transport. To avoid unnecessary mortalities, sensitivity of milkfish eggs to mechanical shock was determined at different ... -
Enrichment of live food with essential fatty acids and vitamin C: effects on milkfish (Chanos chanos) larval performance
(Elsevier, 1998)The effects of essential fatty acids (EFA) and vitamin C-enriched live food on growth, survival, resistance to salinity stress and incidence of deformity in milkfish larvae reared in tanks were investigated. Larvae were ... -
Contribution of natural food and supplemental feed to the gut content of Penaeus monodon Fabricius in a semi-intensive pond system in the Philippines
(Elsevier, 1998)Juvenile Penaeus monodon were stocked in grow-out ponds and fed a compound diet at high rates for 19 weeks under semi-intensive conditions. At three stages of the rearing period (weeks 6, 11 and 16), the gut content of the ... -
Evaluation of leguminous seed meals and leaf meals as plant protein sources in diets for juvenile Penaeus indicus
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)The potential of locally available legumes (white cowpea, Vigna unguiculata, and green mung-bean, Vigna radiata) and leaf meals (papaya, Carica papaya, and cassava, Manihut esculenta) in combination with defatted soybean ... -
