Ecology 6th Edition by Charles Krebs

تمرين 5

Fish communities consist of many different species, only a few of which are typically the focus of commercial or recreational fishing. One way to manage such fisheries is to use standard criteria for maximum sustained yield on the single species of interest, and to ignore the other species in the community. Discuss how this simplified approach might have disastrous consequences for the other species in the ecosystem. Walters et al. (2005) discuss this issue.
