Although conservation efforts have reduced threats, the endangered smalltooth sawfish, Pristis pectinata, is still at risk from anthropogenic effects such as entanglement in recreational and commercial fishing gear. From 2017 to 2021, data from field research and the public in Florida documented 176 individuals that were entangled, injured, or killed by debris or human interactions. While entanglements in fishing gear (e.g., trawls, fishing tackle) remain the most frequent threat, interactions with household items have increased. Since 2017, 30 sawfish were reported with encircling debris (e.g., monofilament loops, rubber bands, ball bungee cords) around anterior parts of their bodies. Ball bungee cords have emerged as a problem, likely related to the popularity of their use in securing boat lift canopy covers. Collectively, encircling items have interfered with eye, spiracle, gill, and mouth function. Continued outreach is a priority to address these pollutants, their sources (e.g., manufacturers), and their effects on recovery.
尽管保护工作已经减少了威胁，但濒危的小齿锯鳐（Pristis pectinata）仍然面临着人为影响的威胁，例如在娱乐和商业捕鱼设备中缠绕。从 2017 年到 2021 年，佛罗里达州的实地研究和公众数据记录了 176 条因碎片或人类互动而缠绕、受伤或死亡的个体。虽然渔具缠绕（例如拖网、渔具）仍然是最常见的威胁，但与家居用品的互动有所增加。自 2017 年以来，报告了 30 条锯鳐身体前部被缠绕的碎片（例如单丝环、橡皮筋、球型蹦极绳）。球型蹦极绳已成为一个问题，可能与它们在固定船用提升遮阳篷方面的广泛使用有关。总的来说，这些缠绕物干扰了眼睛、呼吸孔、鳃和嘴的功能。持续开展外展活动是解决这些污染物、其来源（例如制造商）以及它们对恢复的影响的优先事项。
