Natural Production Mechanisms of Marine Fisheries

Natural production mechanisms of marine fisheries

Natural production mechanisms are defined as those physical variables that have a direct relation to the abundance of biotic resources and control their magnitude, variability and persistence. In the coastal zone an ecological understanding of its systems requires an integrated analysis of the physical environmental and biological processes. For instance, fishery biology is applied ecology and thus of transcendent importance for the rational prospecting, evaluation, exploitation, and administration of demersal resources, is the integral ecological knowledge of biotic resources and its link to the physical environment.

World-wide, the state of tropical coastal demersal fisheries lacks the generalized information that would permit a deeper understanding of the problems of ecological interpretation and evaluation with good methodological bases. ...
