The capture of ornamental fish is one of the main economic activities of riverine families in the Amazon. However, studies regarding the local ecological knowledge of workers in this activity are still incipient. In view of this, we have studied and explored the local ecological knowledge of artisanal fishers who specialize in the capture of fish for the aquarium trade in the middle part of the Negro River basin and investigated issues related to the ecological aspects of the fish species that are targeted by this trade in the region.
Therefore, we conducted semi-structured interviews and applied questionnaires to artisanal fishers of ornamental fish (N = 89), from the municipality of Barcelos, from January to April 2016.
In total, 41 popular names were cited, which correspond to four ethnocategories and 10 families. The main species were Paracheirodon axelrodi (12.5%), Hemigrammus bleheri (8.3%), Ancistrus dolichopterus (6.4%), Symphysodon discus (5.3%), and Potamotrygon motoro (3.8%). According to the fishers, the species of fish known in the region as "piabas" have a preference for living in clusters (28.9%) and carry out migratory movements (26.1%). The diet of local fish species reported by fisheries is diverse, though mainly based on periphyton (42.2%), and the reproductive cycle directly influenced by the period of flooding of rivers in the region (37.6%) CONCLUSION: Our study revealed that the fishers possess information on the ecological aspects of local ornamental fish species, many of which are consistent with scientific literature. The information presented may assist in the decision-making process for the management of local fishery resources and contribute to the resumption of growth and sustainability in the capture of ornamental fish.
捕捞观赏鱼是亚马孙河流域家庭的主要经济活动之一。然而，对于从事该活动的工人的本地生态知识的研究仍处于初始阶段。有鉴于此，我们研究和探讨了专门从事黑河流域中游地区观赏鱼捕捞的渔民的本地生态知识，并调查了该贸易中目标鱼类的生态方面的问题。
因此，我们于 2016 年 1 月至 4 月，对来自巴塞罗斯市的 89 名观赏鱼捕捞渔民进行了半结构化访谈和问卷调查。
总共引用了 41 个通俗名称，对应于四个民族类别和 10 个科。主要的物种有 Paracheirodon axelrodi（12.5%）、Hemigrammus bleheri（8.3%）、Ancistrus dolichopterus（6.4%）、Symphysodon discus（5.3%）和 Potamotrygon motoro（3.8%）。根据渔民的说法，该地区被称为“piabas”的鱼类更喜欢集群生活（28.9%）并进行洄游（26.1%）。渔业中报告的本地鱼类的饮食多种多样，主要以周丛生物（42.2%）为食，生殖周期直接受该地区河流洪水期的影响（37.6%）。
我们的研究表明，渔民掌握了有关当地观赏鱼类生态方面的信息，其中许多信息与科学文献一致。所提供的信息可能有助于地方渔业资源管理决策，并有助于观赏鱼捕捞的恢复增长和可持续性。
