%X 为了解渤海湾口虾蛄开发状态，基于2018~2021年渤海湾底拖网调查数据，利用电子体长频率分析法、基于体长转换的渔获曲线、经验公式等研究口虾蛄生长、死亡和渔业开发利用状况，结果显示，渤海湾口虾蛄渐进体长和平均生长速率分别为19.68 cm和0.38/年，总死亡系数、自然死亡系数和捕捞死亡系数分别为2.13/年、0.7/年和1.35/年，当前开发率为0.63，研究表明，渤海湾口虾蛄已超出最适开发水平(0.5)，建议降低捕捞压力，并将开捕体长增大至11.75 cm，以保障资源的可持续利用。
In order to understand the development status of Oratosquilla oratoria in Bohai Bay, based on the bottom trawl survey data of the Bohai Bay from 2018 to 2021, the growth, death, and fishery development and utilization status of mantis shrimp were studied using electronic body length frequency analysis, catch curve based on body length conversion, Pauly empirical formula, etc. The results showed that the asymptotic length and K of Von Bertalanffy Growth Function for Oratosquilla oratoria in the Bohai Bay were 19.68 cm and 0.38/year, respectively. The total mortality coefficient, natural mortality coefficient, and fishing mortality coefficient were 2.13/year, 0.7/year, and 1.35/year, respectively. The current development rate was 0.63. The study showed that Oratosquilla oratoria in Bohai Bay had exceeded the optimal development level (0.5). It is recommended to reduce fishing pressure and increase the length of the fishing. Up to 11.75 cm of body length to ensure the sustainable use of resources.
