The ecological impact of tilapia cage culture in Sampaloc Lake, Philippines
(Asian Fisheries Society, 1994)
Sampaloc lake showed imminent biological death as a consequence of intensive tilapia farming in floating net cages. The progressive disappearance of dissolved oxygen in the entire water column may be an irreversible trend ...
Toxicity of four botanical insecticides to fingerlings of Nile tilapia and common carp
(Asian Fisheries Society, 1994)
Static bioassay test was done to determine the toxicity of four botanical insecticides (BI) - Blumea balsamifera leaves, Vitex negundo leaces, Azadirachta indica seeds, Tinospora rumphii stems to fingerlings (0.8 - 1.5g) ...
Growth and survival of Oreochromis niloticus, O. mossambicus and their F1 hybrids at various salinities
(Asian Fisheries Society, 1990)
Growth and survival of Oreochromis niloticus, O. mossambicus, and their F<sub>1</sub> hybrids were studied at various salinities (0-32 ppt) in net cages inside 12-tonne concrete tanks after acclimation. Growth, measured ...
Use of internal reference population for growth rate comparison of tilapia strains. I. In a crowded environment
(1990)
This paper reports an experimental design in which reference fish are included in each replicate to provide internal statistical control over environmental variation. Growth of 10 full-sib families from each of 3 strains ...
Evaluation of free essential amino acid in muscle of Nile tilapia (Oreochromis niloticus), as a basis of amino acid requirement for growth.
(Asian Fisheries Society, 1994)
The free essential amino acid levels in muscle of young Nile tilapia (Oreochromis niloticus) after feeding graded amounts of a corresponding test amino acid were measured in 9 separate experiments to determine if free amino ...
Toxicity of rotenone to milkfish, Chanos chanos, and tilapia, Oreochromis mossambicus
(Asian Fisheries Society, Fish Health Section, 1992)
Milkfish (Chanos canos) and tilapia (Oreochromis mossambicus) were exposed to varying concentrations of rotenone (95-98% active ingredient) to determine the median lethal concentration (LC<sup>50</sup>). The 1, 6, 12, 24, ...
A statistical procedure for using "reference fish" to compare the growth of genetic strains in aquaculture
(Asian Fisheries Society, 1990)
No simple, well-accepted procedures exist for comparing the relative performance of genetic strains of fish in aquaculture environments. The major technical problem is providing adequate statistical replication of ponds ...
