Interaction between test and reference populations when tilapia strains are compared by the “internal control” technique
(Elsevier, 1990)
Several strains of Oreochromis niloticus, O. mossambicus and their hybrids occur in the Philippines, and others are likely to be introduced or developed locally in the near future. Our objective was to study biological ...
Vertical rope cultivation of Gracilaria (Rhodophyta) using vegetative fragments
(Walter de Gruyter, 1990)
Preliminary field culture of Gracilaria using vegetative fragments inserted between braids of ropes suspended vertically inside a floating cage was undertaken to assess the daily growth rate and monthly yield as influenced ...
The macronutrient composition of natural food organisms mass cultured as larval feed for fish and prawns
(Society of Israeli Aquaculture and Marine Biotechnology, 1990)
The macronutrient composition of natural food organisms that are mass cultured as feed for the larval stages of fish and prawns in the SEAFDEC Aquaculture Department was determined by chemical analysis. The food organisms ...
Evaluation of the salinity tolerance of Oreochromis mossambicus, O. niloticus and their F1 hybrids
(Elsevier, 1990)
The salinity tolerance of freshwater-spawned and reared Oreochromis mossambicus, O. niloticus and their F<sub>1</sub> hybrids of various ages was studied. Several tests were conducted using three indices as practical ...
