LHRHa and pimozide-induced spawning of Asian catfish Clarias macrocephalus (Gunther) at different times during an annual reproductive cycle
(Elsevier, 1997)
Captive Clarias macrocephalus were induced to spawn during the off-season (February), before (May), during (August) and end (November) of the natural breeding period to test their seasonal responsiveness to hormone treatment, ...
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 ...
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 ...
Ovarian development and serum steroid hormone profiles in hatchery-bred female catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)
Ovarian development e.g. gonadosomatic index, oocyte diameter, fecundity, histology, and related steroid hormones e.g. testosterone (T), estradiol-17 β (E<sub>2</sub>), 17α, 20 β-dihydroxy-4-pregnen-3-one (DHP), were ...
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, ...
Food selection of early grouper, Epinephelus coioides, larvae reared by the semi-intensive method
(Japan Aquaculture Society, 1997)
The grouper, Epinephelus coioides, larvae were reared in outdoor tanks with nauplii of copepods and/or rotifers, Brachionus rotundiformis as food. Nauplii propagated in tanks consisted mainly of Pseudodiaptomus annandalei ...
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 ...
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 ...
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 ...
