A critical review of shrimp pond culture in the Philippines
(Taylor & Francis, 1993)
The paper reviews and evaluates shrimp pond culture in the Philippines and its ecological and socioeconomic effects. The intertwined histories of the country's mangrove forests and culture ponds are treated in depth; ...
Successive spawning of grouper, Epinephelus suillus (Valenciennes), in a tank and a floating net cage
(Elsevier, 1993)
Wild Epinephelus suillus (Valenciennes) were collected in 1989 to early 1990. To monitor natural spawning in captivity, 6 mature females (3.5–5.0 kg) and 4 mature males (7–12 kg) were transferred to a 4.6×4.6×2 m concrete ...
Requirements of juvenile milkfish (Chanos chanos Forsskal) for essential amino acids
(American Society for Nutrition, 1993)
The dietary requirements of juvenile milkfish (Chanos chanos Forsskal) for essential amino acids were determined in a series of experiments. The fish (< or = 8.0 g) were reared in fiber glass tanks provided with flow-through ...
Broodstock management and egg production of milkfish, Chanos chanos Forsskal
(Blackwell Publishing, 1993)
The milkfish, Chanos chanos Forsskal, industry in the Philippines suffers from a limited supply of wild fry. The demand for milkfish fry has spurred research in artificial propagation to supplement the natural seed supply. ...
Growth response of three Oreochromis niloticus strains to feed restriction
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
Growth of fry from three test strains of Nile tilapia (CLSU, ISRAEL and NIFI) fed restrictively and nonrestrictively were compared. Four-week old fry were matched for size with similarly aged red tilapia fry which served ...
Economics of microalgae (Chaetoceros calcitrans) production using the multi-step method in the Philippines
(Elsevier, 1993)
The use of live microalgae for food during the early stages of the life cycle of shrimp larvae is considered essential. The microalga Chaetoceros calcitrans was mass produced at the Aquaculture Department of the Southeast ...
Growth of Gracilaria sp. (Gracilariales, Rhodophyta) in brackishwater ponds at different stocking densities.
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The specific growth rate (% per day) and net production rate (g per m<sup>2</sup> per day) of Gracilaria sp. cultivated in net cages in a brackishwater pond were determined at different stocking densities (200, 250, 300 ...
Food choice by free-living stages of the tropical freshwater crayfish, Cherax quadricarinatus (Parastacidae: Decapoda)
(Elsevier, 1993)
Food choice by Cherax quadricarinatus was measured from video recordings of the time spent feeding on decayed plant material and zooplankton. Crayfish within the size range 20–75 mm spent a significantly longer time feeding ...
Thyroxine injection of female rabbitfish (Siganus guttatus) broodstock: changes in thyroid hormone levels in plasma, eggs, and yolk-sac larvae, and its effect on larval growth and survival
(Elsevier, 1993)
The thyroid hormone levels in female rabbitfish, Siganus guttatus, plasma, eggs, and yolk-sac larvae were measured before and after thyroxine (T<sub>4</sub>) injection in female spawners at doses of 1, 10, and 100 μg ...
Sustained production of milt in rabbitfish, Siganus guttatus Bloch, by weekly injection of luteinizing hormone-releasing hormone analogue (LHRHa)
(Elsevier, 1993)
Mature male rabbitfish (Siganus guttatus Bloch) received weekly injections of 200 μg of luteinizing hormone-releasing hormone analogue (D-Ala<sup>6</sup>, Pro<sup>9</sup>-LHRH-ethylamide) per kg body weight for 5 consecutive ...
