摘要

角鲨(Penaeus kerathurus)是马尔马拉海小型渔户使用三层刺网捕捞的目标鱼种之一。一般情况下,三层刺网使用 40 毫米的网目尺寸。在本研究中,比较了其他网目尺寸(36 毫米、44 毫米)与 40 毫米传统网目尺寸对选择性和可捕获性的影响。共捕获了 27 个物种,包括 3777 个个体,重 123615 克。角鲈占总个体数的 72.4%,占总重量的 58.3%。商业渔民的 40 毫米网目单位渔获量(CPUE)平均值(±Ss)为 7.73±4.99 克/m.作业-1,而本研究的单位渔获量(CPUE)平均值(±Ss)为 9.92±4.47 克/m.作业-1。36 毫米和 44 毫米备选网目尺寸的 CPUE 值分别为 4.83±2.67 和 7.77±4.92 克/米-作业-1。网目尺寸为 40 毫米的个体 CPUE 值最高。角鲨的平均甲壳长度、总长度和总重量随网目尺寸的增加而显著增加。在马尔马拉海,角鲨的模式长度大于其初次性成熟时的躯干长度。因此,传统网目尺寸和替代网目尺寸均可用于捕捞角鲨。因此,首次描述了马尔马拉海的 P. kerathurus 渔业。替代网目尺寸对渔获量和副渔获物组成、选择性没有显著影响,但降低了捕捞效率。可以对三角网进行新的和额外的修改、创新或改变,以促进可持续的角鲨捕捞。

Effects of traditional and alternative mesh sizes in trammel nets on selectivity and catchability of Penaeus kerathurus (Forskål, 1775) in the Marmara Sea
Penaeus kerathurus is one target species caught with trammel nets by small-scale fishers in the Marmara Sea. Generally, 40 mm mesh size is used in trammel nets. In the present study, alternative mesh sizes (36 mm, 44 mm) were compared with the 40 mm traditional mesh size for their effects on selectivity and catchability. A total of 27 species comprising 3777 individuals and weighing 123615 g were caught. Penaeus kerathurus constituted 72.4 % of the total number of individuals and 58.3 % of the total weight. The mean (±Ss) catch-per-unit-of-effort (CPUE) for the 40 mm mesh size for commercial fishers was determined to be 7.73±4.99 g/m.operation−1, and 9.92±4.47 g/m.operation−1 for the present study. The CPUE values for the 36 mm and 44 mm alternative mesh sizes were determined as 4.83±2.67 and 7.77±4.92 g/m.operation−1, respectively. The highest CPUE value for individuals was detected with the 40 mm mesh size. The mean carapace length, total length and total weight of P. kerathurus significantly increased with mesh size. The model lengths of P. kerathurus were found to be larger than the carapace length at first sexual maturity in the Marmara Sea. So, traditional and alternative mesh sizes can be used to catch P. kerathurus. As a result, P. kerathurus fisheries in the Marmara Sea were described for the first time. Alternative mesh sizes did not significantly affect catch and bycatch composition, selectivity, but they decreased catching efficiency. New and additional modifications, innovations or changes can be made to trammel nets to promote sustainable P. kerathurus fisheries.
