Ichthyofauna diversity of Lake Asejire: Ecological implications
The natural diversity of most aquatic systems has witnessed various changes in stock diversity and abundance resulting from structural changes in habitat, food composition and uncontrolled exploitation. These have altered the ecology of the fish resources with the disappearance of some species and dominance of others. This study seeks to identify the ecological implication of the stock diversity and abundance in Lake...
Population dynamics of the edible clam Meretrix casta (Chemnitz) (International Union for Conservation of Nature status: Vulnerable) from two estuaries of North Kerala, south west coast of India
The population parameters of the edible clam Meretrix casta (Chemnitz) from two estuaries along the coast of north Kerala, Southern India were estimated. M. castahas been cited as vulnerable as per al. (2006a). Growth of M. casta from the east coast has been reported by Abraham (1963), Durve (1970: 73) and Sreenivasan (1983). Jayawickrema and Wijeyratne (2009) have described the population...
Mixed culture (shrimps, oysters and macroalgae) to improve the productivity, and reduce the environmental impact to coastal ecosystem caused by shrimp hatcheries in Mexico
In Mexico, shrimp hatcheries have been developed as intensive monocultures, resulting in hatcheries management troubles, economic losses and environmental impact. Therefore, the aim of this work was compare to a traditional culture vs. a mixed culture. Shrimp juveniles were distributed in aquariums and ponds at the same density (51 shrimps/m2) but ponds, also had oysters and macroalgae. Shrimps in aquaria and ponds were...
