Karyotype of the American green sturgeon. Transactions of the American Fisheries Society
Van Eenennaam AL. Murray JD. Medrano JF.
We report the first karyological analysis of the rare American green sturgeon Acipenser medirostris. We found a mean chromosome number of 249 ± 8 (range, 234–263) with both between- and within-animal variation in chromosome number. Approximately one half of the karyotype comprises very small microchromosomes and the majority of the macrochromosomes are metacentric and submetacentric.
