Larval rearing of the grouper Epinephelus suillus under laboratory conditions
(Elsevier, 1997)A protocol for rearing orange-spotted rockcod, Epinephelus suillus in the hatchery is described. The feeding regime consisted of Chlorella, Brachionus, Artemia and minced fish. With this regime, survival rates at Day 24 ... -
Preliminary investigation of feeding performance of larvae of early red-spotted grouper, Epinephelus coioides, reared with mixed zooplankton
(Springer Verlag, 1997)Larvae of red-spotted grouper, Epinephelus coioides, were reared in outdoor tanks with nauplii of copepods (mainly Pseudodiaptomus annandalei and Acartia tsuensis) and/or rotifers, Brachionus rotundiformis. Grouper larvae ... -
Detection of Vibrio penaeicida in kuruma prawn after transport
(Japanese Society of Fish Pathology, 1997)In Japan, vibriosis caused by Vibrio penaeicida usually occurs in cultured kuruma prawn (Penaeus japonicus) during summer and fall. The causative bacterium can easily be detected from overtly diseased prawns, but from ... -
The growth, survival and production of shrimp (Penaeus monodon) cultured with green mussel (Perna viridis) in semi-intensive ponds
(University of Philippines in the Visayas, 1997)The culture of tiger shrimps (Penaeus monodon) with and without green mussels (Perna viridis) was compared in terms of animal growth, survival, production, and pond water quality. Tiger shrimps (2.6 g) were stocked at ... -
Growth of juvenile Asian seabass, Lates calcarifer, fed varying carbohydrate and lipid levels
(Elsevier, 1997)Growth performance of juvenile seabass (initial mean body weight, 0.90 ± 0.04 g) fed varying carbohydrate and lipid levels were determined using practical diets in a 2 × 3 factorial experiment. Two carbohydrate levels (15 ... -
Changes in shrimp feed quality and effects on growth and survival of Penaeus monodon juveniles
(Elsevier, 1997)Five practical shrimp diets were formulated to contain 1, 10, 20, 50, and 100 g tetraethoxypropane (TEP) kg−1 diet. A diet with no added TEP served as the control. Diets were fed to Penaeus monodon (average ... -
The milkfish fry shortage in the Philippines and supply from fisheries and hatcheries
(University of Philippines in the Visayas, 1997)This paper reviews the history and status of the milkfish fry fishery and hatchery and examines the issue of fry shortage in some detail. The fry fishery in the Philippines is a well developed industry that uses efficient ... -
Isolation of Vibrio spp. from Penaeus monodon (Fabricius) with red disease syndrome
(Elsevier, 1997)From January 1990 to June 1993, 59% of the total juvenile to adult shrimp Penaeus monodon submitted for diagnosis at the Fish Health Section of the Aquaculture Department, Southeast Asian Fisheries Development Center, ... -
Preliminary studies on the rearing of the red-spotted grouper, Epinephelus coioides larvae using copepod nauplii as initial food
(University of the Philippines in the Visayas, 1996)One day old red-spotted grouper (Epinephelus coioides) larvae from SEAFDEC, Iloilo, were packed at 3.300 ind/L and transported to Dagupan, Pangasinan for larval rearing. Transport time was about 10 hours. More than 90% of ... -
Stable carbon and nitrogen isotope ratios of penaeid juveniles and primary producers in a riverine mangrove in Guimaras, Philippines
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 1996)Stable carbon and nitrogen isotope ratios were analyzed for primary producers and juveniles of four penaeid species (Metapenaeus ensis, Penaeus indicus, P. merquiensi and P. monodon) in a riverine mangrove in Guimaras, ... -
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. II. Seasonal variations in the agar quality of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)Three species of agarophytes (Gracilaria changii, G. manilaensis and Gracilariopsis bailinae) collected along the mud flats of Iloilo were investigated to determine the monthly variation in agar yield (%), gel strength (g ... -
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. I. Seasonal variations in the biomass of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)Monthly biomass (g dwt m-2) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii ... -
Growth, survival and feed conversion of juvenile shrimp (Penaeus monodon) fed a betaine/amino acid additive
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)Diets low in animal but high in plant protein were enhanced with a chemoattractant FinnStim (FS), a betaine/amino additive. These were fed to juvenile shrimp, Penaeus monodon, in three tank experiments. All diets were ... -
Use of seaweed meals from Kappaphycus alvarezii and Gracilaria heteroclada as binders in diets for juvenile shrimp Penaeus monodon
(Elsevier, 1996)Two seaweed meals were tested as binders in shrimp diets. In the first study, Kappaphycus alvarezii or Gracilaria heteroclada in dry ground form were added to an isonitrogenous diet at 3, 5, 7 or 10%. The basal diet had ... -
Seasonal availability of calanoid copepods (genus Acartia) in eastern Thailand using a light trap, as food organisms for marine fish larval rearing
(Asian Fisheries Society, 1996)Zooplankton collected by the torch lighting method were investigated in a tropical coastal seawater pond in eastern Thailand. Copepods of the genus Acartia, such as A. sinjiensis, A. erythaea and A. pacifica, were predominant ... -
Valine requirement of postlarval tiger shrimp, Penaeus monodon Fabricius
(Wiley-Blackwell, 1996)The valine requirement of juvenile tiger shrimp, Penaeus monodon Fabricius, was determined. Shrimp postlarvae, PL20, with a mean weight of 14 mg, were randomly distributed in 36 oval 40-L capacity fibreglass tanks at 10 ... -
Methionine requirement of juvenile tiger shrimp Penaeus monodon Fabricius
(Elsevier, 1996)An 8-week feeding trial was conducted to determine the dietary requirement of postlarval Penaeus monodon for the sulfur-containing amino acid methionine. Shrimp postlarvae (mean weight 21 ± 0.3 mg) were reared in 40-1 ... -
