Ompok karunkodu, a new catfish (Teleostei: Siluridae) from southern India.
Ompok karunkodu, a new species of silurid catfish is described from the Amaravathi River, a right-hand tributary of the Kaveri [=Cauvery] River in Tamil Nadu, southern India. Ompok karunkodu can be distinguished from all congeners in the Indian subcontinent in having a markedly convex predorsal profile (vs. with a slight or distinct concavity in the supraethmoidal or supraoccipital region), and...

متن کاملGonadal maturity assessment of buttercatfish (Ompok bimaculatus) from Indian major rivers and tributaries during spawning season
The present work focused to explore reproductive biology of fish from different Indian major rivers and its tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Correlation between fish reproductive parameter of different Indian major rivers and its tributaries showed a significant relationship. Among studied parame...
متن کاملCanadian fishery closures provide a large-scale test of the impact of gillnet bycatch on seabird populations.
In 1992, the eastern Canadian gillnet fisheries for northern cod and Atlantic salmon were largely closed. These large-scale fishery closures resulted in the removal of tens of thousands of gillnets known to inflict high levels of seabird mortality. We used this unprecedented opportunity to test the effects of gillnet removal on seabird populations. Consistent with predictions, we show that the ...
