The exploitation pattern of the invertebrate resource (Oratosquilla oratoria) was investigated in the coastal waters of the Shandong Peninsula, along with the seasonal variation in body length structure, spatial distribution in abundance, and interannual stock status. Results showed that the model with only catch data suggested both stocks in the north and south were suffering from extreme fishing pressure without explicit recovery (North: B/B = 0.468 and F/F = 1.88 in CMSY. South: B/B = 0.349 and F/F = 2.59 in CMSY). However, the other two assessment models indicated that the northern stock began to gradually recover as the fishing pressure dropped to an appropriate level after the original overfished status (North: B/B = 0.738 and F/F = 0.882 in AMSY, B/B = 0.831 and F/F = 0.774 in BSM. South: B/B = 0.164 and F/F = 1.44 in AMSY, B/B = 0.384 and F/F = 1.76 in BSM). Overall, the stock status in the north was better than that in the south. This study suggested that spatial exploitation pattern and quarterly differences should be considered in fishery management process.
对山东半岛沿海无脊椎动物资源（Oratosquilla oratoria）的开发模式进行了研究，包括体长结构的季节性变化、丰度的空间分布和多年种群状况。结果表明，仅根据捕捞数据建立的模型表明，南北两个种群都面临着极端捕捞压力，没有明显的恢复迹象（北：CMSY 中的 B/B=0.468 和 F/F=1.88。南：CMSY 中的 B/B=0.349 和 F/F=2.59）。然而，另外两个评估模型表明，北方种群在捕捞压力下降到适当水平后开始逐渐恢复，因为之前已经过度捕捞（北：CMSY 中的 AMSY 中的 B/B=0.738 和 F/F=0.882，BSY 中的 B/B=0.831 和 F/F=0.774。南：CMSY 中的 AMSY 中的 B/B=0.164 和 F/F=1.44，BSY 中的 B/B=0.384 和 F/F=1.76）。总体而言，北方种群的状况要好于南方种群。本研究建议在渔业管理过程中应考虑空间开发模式和季度差异。
