To effectively manage a body of water for a specific species or type of species, fisheries biologists employ multiple survey and study methods to observe the dynamics of that population or species. They use multiple netting techniques during different seasons and target certain species with each study attempt. However, one of the preferred methods of collecting information about a specific fishery is to ask the people with the most recreation time invested using that fishery, the anglers. In my post Spring Fishing Census, I explained about creel surveys, what they are and why we do them.
