An economic analysis of the modular pond system of milkfish production in the Philippines
(Elsevier, 1989)
In 1980, the annual yield of milkfish ponds in the Philippines was 800 kg/ha while the potential yield is estimated to be 2000 kg/ha. The modular pond system analyzed in this study can largely close the gap between actual ...
Effects of feeding frequency and amount of feeding on the growth of the grouper, Epinephelus malabaricus
(Science and Technology Information Institute, 1989)
The effects of feeding frequency and amount of food on the growth of juvenile groupers (Epinephelus malabaricus) were investigated for 12 weeks of rearing in net-cages set in an earthen pond. The juveniles (110-130 g in ...
Spawning response of mature female sea bass, Lates calcarifer (Bloch), to a single injection of luteinizing hormone-releasing hormone analogue: effect of dose and initial oocyte size
(Blackwell Publishing, 1989)
The effect of various doses of luteinizing hormone-releasing hormone analogue (LHRHa) ranging from 1 to 100 μg/kg body weight on the spawning response of mature female sea bass, Lates calcarifer (Bloch) was tested. A single ...
Effect of fatty acid composition of broodstock diet on tissue fatty acid patterns and egg fertilization and hatching in pond-reared Penaeus monodon
(Asian Fisheries Society, 1989)
The effect of dietary fatty acid composition on tissue fatty acid patterns and Penaeus monodon was evaluated with the use of 3 practical diets. Diets were formulated to contain the same basal components but with various ...
Ovarian maturation stages of the wild giant tiger prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
A qualitative and quantitative study of the ovarian maturation stages of wild-caught Penaeus monodon was conducted to refine the existing method of staging. For industrial purpose, measuring the ovarian width at the first ...
The effect of stress on spawning of brood fish and survival of larvae of the rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1989)
The effects of stress due to handling, and repeated sham and human chorionic gonadotropin (HCG) injections on spawning and survival of the rabbitfish, Siganus guttatus were studied. Results showed that stress significantly ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Use of kappa-carrageenan microbound diet (C-MBD) as feed for Penaeus monodon larvae
(Springer Verlag, 1989)
The performance of an artificial practical diet, kappa-carrageenan microbound diet (C-MBD) was assessed on Penaeus monodon larvae at the SEAFDEC Broodstock and Maturation Experimental Laboratory in March 1986. Shrimps were ...
Comparison of various water replenishment and fertilization schemes in brackishwater milkfish ponds
(Blackwell Publishing, 1989)
The study was undertaken to determine the optimum combination of the frequency of water replenishment and fertilization that can yield the highest growth, survival, and gross production of milkfish. Results indicated that ...
Tolerance level and histopathological response of milkfish (Chanos chanos) fingerlings to formalin
(Elsevier, 1989)
Static 96-h bioassays were conducted on milkfish (Chanos chanos ) fingerlings with formalin at concentrations ranging from 50 to 500 ppm. The 24-, 48-, 72-, and 96-h median lethal concentration values (LC50) were 322, 260, ...
