Ecology is the study of the interrelation ships between organisms and their environment.
The study of ecology benefits anglers in several important ways. Anglers can increase their fishing enjoyment and success by understanding the ecological relationships between the organisms in lakes, ponds, rivers, streams, and the ocean. An awareness of ecological principles helps anglers understand things they've seen outdoors. Anglers who understand ecological concepts will better understand the reasoning behind modern fisheries management decisions. This section provides an introduction to the ecological concepts of habitat, niche, food chains, populations, and carrying capacity.
