While bycatch, the unintentional catch of untargeted species, is one of the main threats to large marine species such as cetaceans, reef sharks and turtles, also known as megafauna, fishers can also be negatively impacted by bycatch. Understanding local fisheries profiles, fishers’ demography and their opinion is thus a necessary part of the strategy to mitigate marine megafauna bycatch in artisanal fisheries. Interviews with fishers were conducted in order to assess the magnitude of marine megafauna bycatch, the dependency of fishers on the fishery and the potential for implementation of bycatch mitigation measures in the artisanal fisheries in Gorontalo, northern Sulawesi (Indonesia). Quantitative and qualitative methods were used to analyse the data. Regression trees showed that cetacean and turtle bycatch were mainly influenced by the fishing location, while bycatch of reef sharks, whale sharks (Rhincodon typus) and mobulids was mainly influenced by the gear type. Cetaceans mostly escaped after being caught or were released. Reef sharks, which were often sold for their meat, were caught in the highest numbers followed by sea turtles. Interviewed fishers had large households, typically averaging more than five people, and mostly were dependent on the fishery, often with few other sources of income. Fishers were generally in favour of reducing bycatch as bycatch often posed a financial threat, due to lost catch and damaged gear. When implementing bycatch reduction measures, it is important to involve fishers in design and implementation of mitigation measures. As awareness on bycatch management and mitigation is growing in Indonesia, measures including recordings (official and self-reporting), capacity building on bycatch specimen handling and release and bycatch mitigation techniques (e.g. gear modifications) are some of the most important bycatch reduction strategies for the country.

苏拉威西省北部(印度尼西亚)哥伦打洛的手工渔业中的海洋大型动物兼捕:一项基于渔民访谈的评估

兼捕是无目标物种的无意捕获,是对大型海洋物种(例如鲸类,礁鲨和海龟,也被称为大型动物)的主要威胁之一,渔民也可能受到兼捕的负面影响。因此,了解当地渔业概况,渔民人口统计学及其意见是减轻手工渔业中海洋大型动物副渔获物战略的必要组成部分。与渔民进行了访谈,以评估海洋巨型动物副渔获物的数量,渔民对渔业的依赖性以及在苏拉威西省北部(印度尼西亚)哥伦塔洛的个体渔业中实施减少副渔获物的措施的潜力。使用定量和定性方法分析数据。Rhincodon typus)和小齿轮主要受齿轮类型的影响。鲸类动物大多数在被捕或被释放后逃脱。经常以肉类出售的礁鲨数量最多,其次是海龟。接受采访的渔民户数众多,通常平均超过五人,并且大多依赖渔业,其他收入来源也很少。渔民普遍赞成减少副渔获物,因为由于渔获物丢失和渔具损坏,副渔获物经常造成经济上的威胁。在实施减少兼捕的措施时,重要的是让渔民参与缓解措施的设计和实施。随着印度尼西亚对兼捕物管理和缓解的认识不断提高,包括录音(官方和自我报告)在内的措施,
