Lake Sangchris. Fish which are spawned early have an advantage over smaller fish in intraspecific competition. Sule (1981) demonstrated how this advantage was exploited in Lake Sangchris. He found that when young-of-the-year Iargemouth bass from heated areas reached 90 mm in length, they were able to consume fish, and their average length increased more than did that of smaller, predominately insectivorous bass from unheated areas. The thermal effluent in Lake Sangchris also benefits Iargemouth bass reproduction by stabilizing water temperature variations which might occur as a result of local climatic.
