摘要:
In 1994 and 1995, 180 lake trout (Salvelinus namaycush) eggs were collected from two spawning sites in southeastern Lake Erie. This provides the first evidence of spawning by lake trout in the lake since stocking began in 1975. Egg abundances (11 and 63 eggs/m(2)) were similar to the mean reported for natural spawning areas in Lake Ontario (52 eggs/m(2)). No spawning was evident at one site sampled in northeastern Lake Erie in 1995.
