Some Genetic Characteristics Of Three Walleye Stocks In Iowa And The Impact Of Fry Stockings In The Cedar River, Vaughn L. Paragamian
Journal of the Iowa Academy of Science: JIAS
Fry stockings of walleye Stizostedion v. vitreum into the Cedar River, Iowa began in the early 1950's, and two studies of the success of these plants gave conflicting results. The objectives of my study were to identify some genetic characteristics in three stocks of walleye and to utilize these characteristics to assess the genetic impact of fry stockings in the Cedar River. Electrophoretic analysis of malate dehydrogenase (MDH) and isocitrate dehydrogenase (IDH) was completed for walleye stocks from the Mississippi and Cedar Rivers, and Big Spirit Lake, Iowa. Phenotypic frequencies of Mdh - B2 and Mdh - B3 …
