A small brood of bass was spawned, and the young grew well; by the end of the summer they were feeding on small warmouths. This combination and sequence of setting up the population allowed the warmouths to become well established, may have limited of sport fishes—was investigated in three populations containing warmouths and largemouths. Three adult warmouths and 30 finger- ling largemouths per acre were released in June, 1952, in Parkhill Pond, a 3-acre pond which contained a large established population of the bullhead minnow, Pime- phales vigilax (Baird & Girard). When the study was terminated at the end of about a year, which included parts of.

Warmouths (Established Population); Largemouth Bass (Adults).—In June, 1951, Kearney Pond ( acres), fig. 25, containing a small population of war- mouths, principally yearlings, was stocked with 5 adult largemouths per acre. In the following October, 20 more adult bass per acre were added, along with 40 finger- ling and adult warmouths per acre. The warmouths produced a moderate-sized brood in 1951. In 1952, the largemouths produced a large brood, the warmouths a relatively small one. This relative spawn- ing success of the two species was main- tained in each of the 3 following years, or until the study was terminated.
