Growth rate, yield and economics of Gracilariopsis bailinae (Gracilariales, Rhodophyta) using fixed bottom long-line method
(Science and Technology Information Institute, 1997)Vegetative thalli of Gracilariopsis bailinae weighing 10 g each were tied to a 5-m monofilament line with plastic strips and laid horizontally on the substrate and were observed to grow at 30 d interval for 9 months. The ... -
Morphological abnormalities in hatchery-bred milkfish (Chanos chanos Forsskal) fry and juveniles
(Elsevier, 1997)Morphological abnormality has been observed in hatchery-bred milkfish juveniles. To characterize and quantify the occurrence of these anomalies, hatchery-bred milkfish juveniles from commercial nursery ponds were sampled, ... -
Influence of pyrite oxidation and soil acidification on some essential nutrient elements.
(Aquacultural Engineering Society (AES), 1997)Influence of soil acidification on some essential nutrient elements was observed experimentally during periodic leaching at 10-day intervals of pyritic soil materials. Pyritic soil in glass columns saturated with distilled ... -
Effect of some vertebrate and invertebrate hormones on the population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis Müller
(Springer Verlag, 1997)Eight vertebrate and invertebrate hormones were screened for their effect on population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis. Growth hormone (GH) or human chorionic ... -
Effects of different illumination levels on zooplankton abundance, feeding periodicity, growth and survival of the Asian sea bass, Lates calcarifer (Bloch), fry in illuminated floating nursery cages
(Elsevier, 1997)The effects of different illumination levels on Zooplankton abundance and feeding periodicity, growth and survival of hatchery-produced Asian sea bass, Lates calcarifer, fry in illuminated floating net cages were determined ... -
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
