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 ... -
Grouper culture in brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1998)Groupers (Epinephelus) are cultured in the Philippines using tiny fry and juveniles caught from the wild. A SEAFDEC/AQD technology verification study on grouper pond grow-out culture resulted in high productivity and ... -
