Population Production and Regulation in the Sea A Fisheries Perspective [Hardcover]

This 1995 text explains how fish populations regulate themselves in relation to climatic change.How do fish populations regulate themselves? David Cushing explains how the effects of climatic changes in the sea have profound implications for the fate of fish larvae. This affects the recruitment of new adults into the population. If recruitment is poor, then fish stocks may fail. Dr Cushing explains that it is only by understanding such processes that we can hope to recognise the implications of global climate change for marine populations. This book will be essential reading for marine ecologists and fisheries biologists alike.How do fish populations regulate themselves?

This book will be essential reading for marine ecologists and fisheries biologists alike.The self-regulation of fish populations and why some fish stocks flourish and then die away are questions that have fascinated fisheries scientists for decades. In this account, David Cushing shows how the fate of fish larvae, which live close to the centers of production in the sea, has a crucial effect on population regulation. He shows how the timing and development of tidal fronts in particular regions have profound implications for fish and plankton production, which in turn affects whether or not enough of the fish larvae live to adulthood. One of the most interesting points made by the author is how vulnerable fish populations are to climate change, and it is only by understanding these processes that we can hope to recognize the implications of global climate change on marine populations.
