Yellow Perch

One reason in particular hindering expansion of yellow perch culture has been relatively slow growth and poor seed quality of currently cultured populations of this species. Continuous research is needed to genetically improve broodstocks to substantially increase growth rate and seed quality through selective breeding. Another roadblock hindering expansion has been low survival and availability of fry and fingerlings. The survival rate of pond nursed fry is dependent on weather, and late winter storms can kill all the fry in ponds overnight. Developing the indoor culture of yellow perch has significant advantages over pond culture. Limiting this possibility has been the poor indoor survival of newly hatched fry to the stage where they are completely feed-trained. Developing strategies to increase indoor survival of larvae and fry using live feed is critical to the yellow perch industry development. Artificial feed costs have increased substantially in recent years and inhibits profit potential and thus expansion of yellow perch culture.  Effective lower cost feeds need to be developed that positively impact a producer’s bottom line by maximizing growth and reducing feed conversion ratios.
