爆炸捕鱼是非法的,生态破坏性捕鱼方法,对许多大规模鱼类来说是致命的。渔民更喜欢使用炸药进行爆炸捕鱼,尤其是土耳其的小规模渔业,因为它需要最小的努力,但仍然导致更高的渔获量。在目前的研究中,20个受控实时爆破结果的演示涉及物种组成,鱼的大小,渔获率,渔获组成,商业/丢弃率,CPUE对鱼类外部和内部异常症状的估计和临床观察。由于其有害影响,爆破试验是在有限数量的特殊许可下进行的。使用PRIMERv6对收集的数据进行了测试,并分析了多样性指数。对于收集的物种之间的相似性,使用聚类分析来检查结果的稳定性。多维缩放(MDS)也用于评估捕捞中的鱼类物种。总共收集了1014个个体(63.8千克),并检查了属于七个科的18种鱼类。根据实验室检查,研究发现,在研究过程中,爆破在采样的鱼类中引起了不同的外部和内部异常症状。
Blast fishing is an illegal, ecologically destructive fishing method, fatal for many fish species at large scales. Blast fishing using dynamite is preferred by the fishers, especially small scale fisheries in Turkey, as it requires minimal effort but still results in higher catches. In the current study, demonstration of 20 controlled real-time blasting results involves species composition, size of fish, catch rates, catch composition, commercial/discard ratios, CPUE estimates and clinical observations of external and internal abnormality symptoms of fish species. Blasting trials were carried out with special permission in limited numbers because of its harmful effect. The collected data was tested using PRIMER v6 and diversity indices were also analysed. For the similarity between collected species cluster analysis was used to examine the stability of the results. Multidimensional scaling (MDS) was also applied for the assessment of fish species in the catch. A total of 1014 individuals (63.8 kg) were collected and 18 fish species belonging to seven families were examined. According to laboratory examinations, it was found that blasting caused different external and internal abnormality symptoms in the sampled fish species during the study.
