Production characteristics of rainbow trout, Oncorhynchus mykiss, and brook trout, Salvelinus fontinalis, under seasonal pond conditions.

摘要

The production characteristics of juvenile rainbow trout, Oncorhynchus mykiss, and brook trout, Salvelinus fontinalis, were compared under winter pond conditions. Juvenile rainbow trout (55.1?.5 g) and brook trout (28.9?.4 g) were stocked at a density of 8750 fish/ha into six 0.04-ha ponds. After 163 days, survival, growth, and feed conversion were similar. The results suggest that brook trout may attain growth rates similar to rainbow trout under winter pond conditions in temperate regions of North America.
