Effect of stocking density and nutrients on the growth and agar gel of Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1995)
The effect of additional nutrients and varying stocking densities (500, 1000, and 2000 g m<sup>-2</sup>) on the growth and physical properties of Gracilariopsis bailinae was determined. Growth was significantly higher (L ...
Survival of Penaeus monodon postlarvae and juveniles at different salinity and temperature levels.
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)
Penaeus monodon postlarvae (PL1, PL5, PL10, and PL15) and juveniles (0.2 and 2 g mean weights) were acclimated gradually within 6 h to test temperatures of 22°, 28°, and 33°C. After 24 h, the postlarvae were abruptly ...

(Fisheries Research Society of the Philippines, 1990)
The binding effect of polymethylolcarbamide (PMC) at the levels 0.5% and 1.0% of a practical diet was compared to that of the other binders such as kappa-carrageenan, sodium alginate, carboxymethylcellulose, cornstarch and ...
Evaluation of different supplemental feeds for milkfish (Chanos chanos) reared in brackishwater ponds
(Elsevier, 1991)
The effects of supplemental feeding on milkfish growth, production, survival, water quality, and economic benefits in brackishwater ponds were evaluated by comparing a rice bran diet, containing 11.3% protein, and two ...
