New research helps fast-track yellow perch production

摘要

I dentifying the need for farming yellow perch and describing the potential value of yellow perch culture was easy; however, accomplishing the desired goal in a financially sustainable manner has proved elusive.An early discovery that female yellow perch grow faster and bigger has been the starting point for a considerable amount of research. However, knowing about this growth difference and using it to advantage for commercial aquaculture has not been accomplished. If the fish are two years old before their sex can be determined, it's really not very important.Recently, Dr. Brian Shepherd and his research colleagues at the USDA Agricultural Research Service (ARS) Dairy Forage and Aquaculture Research Unit in Milwaukee, Wisconsin, and collaborators at the University of Wisconsin-Milwaukee School of Freshwater Sciences, developed a protocol to make more efficient use of this difference in growth rates.
