River regulation and recruitment in a protracted-spawning riverine fish.
We present and test an extension of the "match/mismatch" hypothesis that attempts to explain the persistence, under conditions of flow alteration, of small, short-lived, native, riverine, fish species. The premise is that flow alteration typically changes environmental conditions, such as temperature and prey abundance, which may affect survival during the larval period of fishes. This "window-...

15 صفحه اولEffects of different feed items on the growth and survival of endangered riverine catfish
The study was conducted to determine a suitable feed for the desirable growth of riverine catfish Rita rita (Hamilton) from January 2006 to December 2006. The experiment had three treatments with three replicates. Nine chambers of the raceway each of size 1.83 × 1.12 sq meter were used. Local prawn, chicken viscera and commercially available formulated feed (CP) were supplied in treatment T1, T...
