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...
متن کاملFeed-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...
متن کاملTgm1-like transglutaminases in tilapia (Oreochromis mossambicus)
Among the adaptations of aquatic species during evolution of terrestrial tetrapods was the development of an epidermis preventing desiccation. In present day mammals, keratinocytes of the epidermis, using a membrane-bound transglutaminase (Tgm1), accomplish this function by synthesizing a scaffold of cross-linked protein to which a lipid envelope is attached. This study characterizes the abilit...
متن کاملTol2-mediated transgenesis in tilapia (Oreochromis niloticus).
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
متن کاملVisual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.).
Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive beh...
