Recent trends in inland fisheries management have attempted to address the problems created by societal development to improve the aquatic environment for biodiversity and allow for sustainable exploitation of the resources (Arlinghaus
et al.2002). The principal mechanisms of fisheries management concentrate on four categories of action, each with distinct objectives.These are: fish stock enhancement (stockingandintroductions); rehabilitation and habitat manipulation for fisheries purposes, includingbiomanipulation;fisheries regulations; and conservation and protection
of fish and fisheries.
