Resumen
Descripción
It has been known for centuries that marine organisms aggregate around floating objects and many of today’s theories that try to explain the ecological context of such behavioral evolutionary conditions, are still inconclusive. One aspect that is certain is that this particular animal behavior led fishers to intentionally utilize artificial resource aggregating objects to increase fishing efficiency. An immediate added result has been the increase of exploitation rates as fishing effort units as sociated with such devices capture a larger fraction of the stocks per unit of fishing time. Fish Aggregating Devices (FADs) may take many different designs and ways of operating (e.g. drifting and moored or anchored FADs) mostly as a function of population dynamics and ecosystem characteristics of the resources sought by fishers. The discourse as to whether FADs increase population production or simply increase population densities that enhance fishery production are still in debate.
