. Bulletin. Natural history; Natural history. March, 1965 Starrett & Fritz: Fishes of Lake Chautauqua 45 now seining at Lake Chautauqua (1950-1959), only one large year-class of bigmouth buffalo appeared in the hauls, that being in 1953 (Table 30). In the fall of 1955, the largest members of the 1953 year-class appeared in the commercial seine collections as 3-year- old fish (Fig. 18). The 1953 year-class is designated on the bar graphs in black. Fig. 18 shows that this year-class dominated the catch from 1955 through 1958. Earlier the buffalo fishery was dominated by the 1948 year-class.

Earlier the buffalo fishery was dominated by the 1948 year-class. In the fall of 1951, this large year-class (stipple on graph) appeared in the commercial seine hauls as 4-year-old fish (Fig. 18). It remained readily dis- tinguishable from other broods in the commercial seine hauls through 1956. The annual additions of bigmouth buffalo to the adult population were in- sufficient to maintain a large-size popu- lation in the face of heavy fish removal. There appeared to be only a limited amount of recruitment from the Illinois River. 1951 (380 FISH). 1952(181 FISH) 15,0-1 16,0 24D 160 1953 (229 FISH) T I 1 1 1 1 1 1 1 1 1 1 1 1 1 r- 15,0 16,0 190 210 230 270 290 1954 (181 FISH) 170 270 32,0 1956 (399 FISH) 170 18X) 24,0 270 320 1957 (485 FISH) n 1 1 1 1 1 1 1 1 1 1 1 t ^I "^ 1"" I ' 160 170 ISO 270 29,0 32 0 -I r 1 1 1 1 1 1 1 1- 150 160 170 250 270 310 320 TOTAL LENGTH IN INCHES Fig.
