摘要石斑鱼(Epinephelus Morio)是美国和墨西哥商业渔业的重要组成部分。利用标准化抽样设计，在佛罗里达州西部大陆架和墨西哥坎佩切海岸进行了独立于渔业的长线调查(2001-2002年)。很难发现数量和大小的真正差异，但通过使用标准的收集和老化方法，偏差水平被保持在最低水平。与西佛罗里达陆架相比，坎佩切浅滩的相对丰度更高(分别为1.74和0.63红石斑鱼/100钩小时)。来自坎佩切海岸的鱼在长度和重量上也明显较小。红石斑鱼的长度、重量和相对丰度的差异可能是由于历史上的捕捞压力和管理法规，或者是由于每个区域对红斑石斑鱼的有效载重量。这些差异对过度捕捞的种群如何恢复和维持具有重大影响。
Abstract Epinephelus morio (Red Grouper) is an important component of commercial fisheries for the United States and Mexico. Fishery-independent long-line surveys that utilized standardized sampling designs were conducted along the west Florida shelf, Florida and Campeche Bank, Mexico (2001–2002). Detecting true differences in abundance and sizes are difficult, but by using standard collection and aging methodologies, the level of bias was kept at a minimum. Relative abundance was higher in the Campeche Bank compared to the west Florida shelf (1.74 and 0.63 Red Grouper/100 hook hr, respectively). Fish from the Campeche Bank were also significantly smaller at length and weight. Differences in length, weight, and relative abundance of Red Grouper may be because of historical fishing pressure and management regulations, or the available carrying capacity of each area for Red Grouper. These differences have a substantial impact on how an overfished population can recover and be sustained.
