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 ...
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 ...
Experiments on virulence dose and portals of entry for Aeromonas hydrophila in walking catfish
(American Fisheries Society, 1996)
Aeromonas hydrophila, isolated from chevron snakehead Ophicephalus (=Channa) striatus affected with epizootic ulcerative syndrome (EUS), was injected intramuscularly into healthy walking catfish Clarias batrachus at varying ...
Arginine and threonine requirements of milkfish (Chanos chanos Forsskal) juveniles
(Elsevier, 1991)
Growth studies were conducted with milkfish (Chanos chanos Forsskal) juveniles to determine the quantitative requirements for arginine and threonine. The amino-acid test diets (40% crude protein) contained casein and gelatin ...
Mercury and selenium interaction: A review
(Elsevier, 1991)
This paper reviews studies on mercury and selenium interaction. It includes the effects of selenium on mercury toxicity on the organism, organ/tissue, and subcellular levels. The paper also touches on possible mechanisms ...
Accumulation and excretion of metal granules in the prawn, Penaeus monodon, exposed to water-borne copper, lead, iron and calcium
(Elsevier, 1994)
Juveniles of the giant tiger prawn, Penaeus monodon, were exposed for 10 days to 1 mg/l copper, lead, iron or calcium in order to investigate the formation and accumulation of metal granules in major soft tissues as well ...
Lipid and fatty acid composition of milkfish (Chanos chanos Forsskal) grown in freshwater and seawater
(Elsevier, 1992)
The lipid and fatty acid compositions of the various organs of milkfish fed with an invariant diet and reared in seawater (SW) and freshwater (FW) were determined using column chromatography and gas chromatography. ...
Optimum dietary protein level for growth of bighead carp (Aristichthys nobilis) fry in a static water system
(Elsevier, 1991)
Isocalric diets (290 kcal digestible energy/100 g) with protein levels ranging from 20 to 50% in increments of 5% were fed to bighead carp fry (3.8±0.2 mg mean body weight and 9.8±0.1 mm total length) for 7 weeks. Growth ...
Size- and weight-dependent cannibalism in hatchery-bred sea bass (Lates calcarifer Bloch)
(Blackwell Publishing, 1991)
The relationship of predator size to maximum prey size, and predator weight to weight of prey consumed among cannibalistic sea bass (Lates calcarifer Bloch) in a hatchery were assessed. Maximum prey size was computed from ...
Low-cost feed for Penaeus monodon reared in tanks and under semi-intensive and intensive conditions in brackishwater ponds
(Elsevier, 1997)
Experimental diets for juvenile Penaeus monodon were formulated incorporating inexpensive indigenous raw materials. Local fish meal and cowpea meal were tested as replacements for imported protein sources and the diets did ...
