We sought to determine if abundance of larval yellow perch Perca flavescens could predict abundance of age‐0 juvenile perch in late summer. Yellow perch larvae and juveniles were sampled from six eastern South Dakota glacial lakes in 1997. The number of age‐0 yellow perch caught per seine haul in late summer was positively related to larval abundance in late May and early June ( N = 6, r = 0.90, P = 0.01). When data collected from two eastern South Dakota lakes in 1995 and 1996 were added to this assessment, we also found a significant positive relation ( N = 10, r = 0.88, P = 0.0009). Thus, biologists in eastern South Dakota can use larval yellow perch abundance as an early indicator to determine which water bodies are likely to have a weak naturally produced year‐class and then can evaluate the success of fingerling perch stocking strategies.
