Influence of probiotic immobilized on enterosorbent on growth intensity and physiological parameters of red tilapia (Oreochromis mossambicus × Oreochromis niloticus)

INFLUENCE OF WATERBORNE CADMIUM ON THE GROWTH AND IMMUNE-PHYSIOLOGICAL PARAMETERS OF NILE TILAPIA (Oreochromis niloticus)

Nile tilapia, Oreochromis niloticus (65.2±2.2 g) were randomly distributed into 12 glass aquaria to represent 4 treatments (3 replicates per treatment). Fish were exposed to cadmium chloride at concentrations of 0.0 (control), 0.05 (T1), 0.10 (T2) and 0.15 mg L -1 (T3) for 4 weeks. After the first, third and fourth week, fish were immediately anesthetized and blood was collected. Fish weight wa...

Effects of triploidy induction on growth and masculinization of red tilapia [Oreochromis mossambicus (Peters, 1852)×Oreochromis niloticus (Linnaeus, 1758)]

Feed-based vaccination regime against streptococcosis in red tilapia, Oreochromis niloticus x Oreochromis mossambicus

BACKGROUND Streptococcosis is an important disease of tilapia throughout the world. In Malaysia, streptococcosis outbreak was commonly reported during the 3-month period of high water temperature between April and July. This study describes the duration of protection following single and double booster dose regimes against streptococcosis in tilapia using a feed-based vaccine containing formali...

Euryhaline tilapia Oreochromis mossambicus

regulated by, and suited to, the environment in which they reproduce. In many teleosts, which spawn in either freshwater or seawater, sperm motility is initiated by osmotic shock when sperm are ejaculated. These osmolality dependent regulatory systems are quite different in freshwater cyprinid teleosts, such as carp, gold fish and zebrafish, and marine teleosts, such as the pufferfish and floun...

Acclimation responses of gill ionocytes of red tilapia (Oreochromis mossambicus × O. niloticus) to water salinity and alkalinity

To understand the acclimation strategies of red tilapia to different environments, this study aimed to evaluate different responses of red tilapia (O. mossambicus × O. niloticus) to salinity (10-30‰), alkalinity (1-3 gL-1 NaHCO3) and salinity and alkalinity (10/1-30/3 ‰/gL-1NaHCO3) environments. Localization, type, size, and numeration of gill ionocytes were investigated on the sa...
