Induction of ovulation in F1 Malaysian mahseer, Tor tambroides (Bleeker, 1854) by using synthetic and non-synthetic hormones

Tor tambroides is an important and highly valued freshwater fish. In Malaysia, wild populations of this species has undergone declines in range and abundance due to degradation of their natural habitat. Due to economic important and concerns about their conservation, a culture artificial propagation...
