Iran contributes to the stock enhancement of several economically valuable fish species, including the Caspian salmon, S. trutta caspius, by producing and releasing millions of fingerlings into the sea. This work was conducted to determine the production costs of the Caspian salmon fingerlings in the years 2002 and 2003. For this purpose, a questionnaire was prepared and filled in by an expert ...

Marine ranching has been proposed as a promising solution to manage the depleted coastal fishery ecosystem in recent decades across China. integrates practices of artificial habitat-based with aquaculture-based enhancement. Assessing ecological carrying capacity target species for enhancement is precondition determining optimal numbers release, particularly those whose habitat restrictions have...

This paper presents a survey on soil Pb contamination around Paris (France) using the French soil monitoring network. The first aim of this study is to estimate the total amount of anthropogenic Pb inputs in soils and to distinguish Pb due to diffuse pollution from geochemical background Pb. Secondly, this study tries to find the main controlling factors of the spatial distribution of anthropog...

Management of the eel fisheries of the River Shannon, Ireland’s largest river system, has involved van ous stock enhancement measures since 1959. Declining natural recruitmenr levels have limited the effecriveness of stocking programmes for nearly two decades. Observations on declining yellow eel stocks in several major lakes have been supported by the results of studies undertaken annually on ...

Fisheries enhancements are management approaches involving the use of aquaculture and habitat technologies (in broadest sense) to enhance or restore fisheries. The most commonly used include hatchery rearing release aquatic animals provision artificial structures such as reefs. Both associated with distinct fields knowledge communities practice. Recent calls expand broaden role in marine conser...

With increased market integration, the current world financial markets have become more closely correlated and interdependent over time.
