Gill lesions in Nile tilapia Oreochromis fingerling associated with acute malathion poisoning.
(Science and Technology Information Institute, 1994)
The hispathological changes in gills of Nile tilapia, Oreochromis niloticus, fingerlings exposed to 5.3 mg/l (96-h LC50) malathion are described. These changes include hypertrophy of epithelial cells after 3 h, epithelial ...
Reproductive performance of four red tilapia strains in different seed production systems
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)
The reproductive efficiency of one Thai red tilapia strain (NIFI) and three genetically diverse Philippine red tilapia strains (BFS, FAC, and PF) were compared. Breeders from each strain were stocked separately in land-based ...
