This paper describes the fishing profile and the temporal variation in the commercial landings of elasmobranchs in a global hotspot for their conservation and investigates the variables that influenced the landings. Census data on commercial catches were obtained between April 2008 and October 2010 from nine landing sites in Bragança (Pará, northern Brazil). Five vessel types, four fishing gears, and eight fishing techniques engaged with elasmobranch capture were identified. A total of 2,357 landings were recorded, with a total production of 354 t. The highest yields were recorded in 2009, with sharks being harvested mostly by small and medium-sized vessels, and batoids, by small vessels and canoes. Drifting nets and longlines played a prominent role in elasmobranch fisheries. The results show that the landings were influenced by days at sea, which is common in tropical fisheries. The elasmobranch data series is discontinuous as statistics are absent for most fishing sites albeit imperative for proper management, as well as relevant for decision-makers focusing on their conservation.
本文描述了在全球鲨鱼保护热点地区的捕捞概况和商业渔获的时间变化，并研究了影响渔获的变量。2008 年 4 月至 2010 年 10 月，从巴西北部帕拉州布拉干萨的 9 个上岸点获取了关于商业捕捞的普查数据。确定了 5 种船舶类型、4 种渔具和 8 种捕捞技术用于捕捞鲨鱼。共记录了 2357 次上岸，总产量为 354 吨。2009 年的产量最高，鲨鱼主要由中小型船只捕获，而鳐类则由小型船只和独木舟捕获。漂流网和延绳钓在鲨鱼渔业中发挥了重要作用。结果表明，渔获量受出海天数的影响，这在热带渔业中很常见。尽管对于适当的管理和决策者关注其保护至关重要，但由于大多数捕捞地点都没有统计数据，因此鲨鱼数据系列是不连续的。
