Entanglement in marine debris is a contributing factor in Steller sea lion (SSL; Eumetopias jubatus) injury and mortality. We quantified SSL entanglement by debris type, sex and age class, entanglement incidence, and estimated population level effects. Surveys of SSL haul-outs were conducted from 2000-2007 in Southeast Alaska and northern British Columbia. We recorded 386 individuals of all age classes as being either entangled in marine debris or having ingested fishing gear. Packing bands were the most common neck entangling material (54%), followed by rubber bands (30%), net (7%), rope (7%), and monofilament line (2%). Ingested fishing gear included salmon fishery flashers (lures: 80%), longline gear (12%), hook and line (4%), spinners/spoons (2%), and bait hooks (2%). Entanglement incidence was 0.26% (SD=0.0064, n=69 sites). "Lose the Loop!" Simple procedures such as cutting entangling loops of synthetic material and eliminating the use of packing bands can prevent entanglements.
海洋垃圾缠绕是导致海狮（Eumetopias jubatus）受伤和死亡的一个因素。我们通过垃圾类型、性别和年龄组、缠绕发生率来量化海狮的缠绕情况，并估计种群水平的影响。我们于 2000 年至 2007 年在阿拉斯加东南部和不列颠哥伦比亚省北部进行了海狮栖息地的调查。我们记录了 386 只各种年龄的海狮，它们要么被海洋垃圾缠绕，要么吞食了渔具。捆扎带是最常见的颈部缠绕物（54%），其次是橡皮筋（30%）、渔网（7%）、绳索（7%）和单丝鱼线（2%）。吞食的渔具包括鲑鱼渔业的闪光器（鱼饵：80%）、延绳钓渔具（12%）、鱼钩和钓线（4%）、旋转亮片/勺子（2%）和诱饵鱼钩（2%）。缠绕发生率为 0.26%（SD=0.0064，n=69 个地点）。“摆脱缠绕！”简单的程序，如切断合成材料的缠绕环并消除捆扎带的使用，可以防止缠绕。
