Abstract
Larval Walleye and yellow perch populations in Spirit Lake, IA, were sampled using standardized tow net hauls in 9 weekly intervals during May July 1973-75. Annual catch means were 2.6, .9 and 1.7. larval walleye and 11, 23 and 81 larval yellow perch per tow, respectively. The annual maximum larval. Yellow perch density probably varied less than indicated. Seasonal catch of both fish species was unimodal, characterized by systematic declines in larval abundance after the modal density. Both fish species were randomly distributed.
