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
Garcia, Luis Maria 
(Blackwell Publishing, 1989)
(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 ...

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 ...

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 ...

Effect of storage temperature on the quality of diets for the prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
The effect of storage temperature was evaluated on the basis of growth response of prawns fed for 10 weeks with diets stored at 0°C, 10°C, 28°C-31°C (ambient temperatures) and 40°C for a period of 10 weeks. Prawns were ...

Preliminary results of feeding aquatic macrophytes to Penaeus monodon juveniles
Primavera, Jurgenne ; (Elsevier, 1989)
; (Elsevier, 1989)
Penaeus monodon juveniles (PL<sub>50</sub>) were fed live and decaying aquatic macrophytes and a commercial grow-out pellet (40% crude protein) in 80-l glass tanks over a 30-day period. Growth and survival were significantly ...
