Development of a Commercially Viable Yellow Perch ('Perca flavescens') Culture System.

摘要

A study was designed to determine if yellow perch fingerlings collected from a wild population would accept a practical diet. After 34 days, 100% of the fish examined had feed in their digestive tracts. Growth rates of stunted and non-stunted yellow perch fingerlings fed practical diets were determined. Trap nets with 1.5 and 2.0 inch mesh and seines were found to be suitable methods to harvest yellow perch from wild populations. There were no apparent problems with fish transported in cool water (11 C) and at densities not to exceed 1.5 pounds of fish per gallon of water. Based on growth projections, stunted 10 to 13 cm yellow perch could be grown to harvestable size (19.5 cm) within 33 weeks; non-stunted 8 to 10 cm yellow perch fingerlings would require approximately 41 weeks.
