摘要

长重关系（LWR）对于区域间的比较生命史研究、保护策略和生态系统建模至关重要。它们提供了关于生态系统中人口增长、健康和福祉的重要信息。本文报道了2004年至2019年间在马德拉群岛350米至2500米深处捕获的八只软骨鱼的长度和重量关系以及描述性统计数据。共对767个标本进行了研究，观察到参数b（相对生长速率）在鳞片中央藻雄性的2.558和王子Etmopterus princeps雌性的3.494之间波动。这项研究首次包括马德拉水域这8种软骨鱼类的LWR。

Length-weight relationships for eight Chondrichthyes from the north-eastern Atlantic Ocean

Length-weight relationships (LWRs) are pivotal for comparative life-history studies, conservation strategies and ecosystem modelling among regions. They provide essential information on the growth, fitness and wellbeing of a population in an ecosystem. Length and weight relationships and descriptive statistics for eight Chondrichthyes, caught off the Madeira archipelago between 2004 and 2019 from depths ranging from 350 to 2500 m, are herein reported. A total of 767 specimens was studied and it was observed that the parameter b (relative growth rate) oscillated between 2.558 for males of Centrophorus squamosus and 3.494 for females of Etmopterus princeps. This study is the first to include the LWRs for these 8 Chondrichthyes species in Madeira waters.
