Regulated Sex Control in Commercially Important Fishes - A Physiological Perspective

Introduction Developments in the management of fish reproduction have had major impacts on the growth of aquaculture. The capability to spawn fishes under controlled conditions ensures an adequate supply of young for growout, whether for food or stocking (Zohar, 1989; Yaron and Zohar, 1993). Artificial propagation techniques have facilitated worldwide introduction of important species by removi...

Toxic metals in the muscle and liver of five main commercially-important fishes from the Persian Gulf, Southern Iran

The purpose of this study was to determine and compare the concentrations of six toxic metals (Cd, Pb, Fe, Cu, Zn, Mn) in the muscle and hepatic tissues of five commercially important fish species including narrow-barred Spanish mackerel, Scomberomorus commerson, Black pomfret, Parastromateus niger, Silver pomfret, Pampus argenteus, blackspot snapper, Lutjanus fulviflammus and Tigertooth croake...

Heavy Metals Accumulation in Five Commercially Important Fishes of Parangipettai, Southeast Coast of India

Investigations on the accumulation of heavy metals five of the most commercially important fishes in the Parangipettai coastal waters were selected and analyzed for the Zn, Pb, Cr, Co and Cd concentrations in the muscles. The results revealed that the Cr and Zn concentrations were the highest; followed by Pb<Cd<Co being the lowest in the five species of fish tissue. The muscle concentrations of...

Total petroleum hydrocarbon in the tissues of some commercially important fishes of the Bay of Bengal.

The present study reports the level of total petroleum hydrocarbon (TPH) in 27 commercially important fish, crustaceans and cephalopods from Orissa coast, Bay of Bengal to provide the baseline data for oil contamination in marine biota. The results showed significant differences in the TPH concentration in different species. Of all fish, Carangoides malabaricus showed the maximum TPH level (av....
