Analysis of the mitochondrial DNA control region resolved two stocks of whitemouth croaker Micropogonias furnieri in Uruguayan waters, one in the Río de la Plata and the other on the Uruguayan shelf. The whitemouth croaker is the most important coastal fishery resource along the coast and has the greatest commercial importance in the Río de la Plata and its oceanic front. The number of pair-wise differences (pi) and haplotype diversity (h) showed significant differences between the two regions. Frequencies of mtDNA haplotypes did not differ between Río de la Plata from Bahia Blanca M. furnieri. Samples from the oceanic front showed greater genetic variability and a larger effective number of females that were an order of magnitude larger than that in Río de la Plata. Mismatch distributions showed evidence of a recent population expansion in the oceanic region, beginning c. 40,000 b.p. The presence of two stocks of the M. furnieri in the study area should be considered in the management of this species' fishery.
对线粒体 DNA 控制区的分析确定了乌拉圭水域两种白口鱼 Micropogonias furnieri 的种群，一种在拉普拉塔河，另一种在乌拉圭大陆架上。白口鱼是沿海地区最重要的渔业资源，在拉普拉塔河及其海洋前缘具有最大的商业重要性。两个区域之间的碱基对差异数 (pi) 和单倍型多样性 (h) 存在显著差异。拉普拉塔河和 Bahia Blanca 的 M. furnieri 的 mtDNA 单倍型频率没有差异。来自海洋前缘的样本显示出更大的遗传变异性和更大的有效雌性数量，是拉普拉塔河的数量级。歧点分布表明，海洋区域的种群在大约 40000 年前发生了最近的扩张。在研究区域中存在两种 M. furnieri 种群，这应该在该物种渔业管理中加以考虑。
