摘要

对加那利群岛（大西洋中东部）附近 15 种中深海虾类的长度-重量关系（LWRs）进行了估算。使用商业半中上层拖网对三次研究活动中采集的个体进行了总长度、头胸甲长度和总重量的测量。在所采集的物种中，最多的科为 Sergestidae 和 Oplophoridae，分别有 8 种和 3 种。总体而言，60%的物种呈等距生长，33.3%呈负异型生长，6.7%呈正异型生长。这15个低纬度生长曲线是对西北非地区中上层虾类物种的首次贡献，有助于了解这些甲壳类动物的相对生长情况。

Length-weight relationships of 15 mesopelagic shrimp species caught during exploratory surveys off the Canary Islands (central eastern Atlantic)

Length-weight relationships (LWRs) were estimated for 15 mesopelagic shrimp species off the Canary Islands (central eastern Atlantic). Total length, cephalothorax length and total weight were taken for individuals collected during three research campaigns using a commercial semi-pelagic trawl net. The most represented families among the collected species were Sergestidae and Oplophoridae, with eight and three species, respectively. Overall, 60% of the species showed isometric growth, 33.3% negative allometry and 6.7% positive allometry. These 15 LWRs are the first contribution on mesopelagic shrimp species from the northwest Africa region, contributing to knowledge on the relative growth of these crustaceans.
