The length–weight relationships (LWRs) were estimated for 12 fish species. The species were collected monthly from the commercial catch of small‐scale fisheries using gillnets (mesh size 7.6–15.2 cm, length 200–1,000 m, 6–48 hr of operation during the day) and longlines (surface and bottom, 300 hooks, sardine bait, operation during the day) in the period October 2017 to July 2018 along the Pacific coast of Guatemala. Most values for the parameter (b) of the length‐weight equations were within the commonly expected range (2.50–3.50) except for two species: Bagre pinnimaculatus (2.22) and Menticirrhus panamensis (3.56). All values for the coefficient of determination (r²) were above .95 and thus the estimates can be considered reliable. Besides novel LWRs we provide for some species estimates which include a new TLmax not yet involved of any LWR studies.

危地马拉太平洋沿岸的12种海洋鱼类与小型渔业的长度-重量关系

估计了12种鱼类的长度-重量关系（LWR）。该物种每月使用刺网（网眼尺寸7.6–15.2厘米，长度200–1,000 m，白天工作6–48个小时）和延绳钓（表面和底部，300个钩，沙丁鱼饵，白天运行）在危地马拉太平洋沿岸的2017年10月至2018年7月期间。对于参数（最值b的长度权重方程）为除了两个物种常用预期范围（2.50-3.50）内：巴格雷pinnimaculatus（2.22）和Menticirrhus panamensis（3.56）。所有确定系数的值（r ²）高于.95，因此估算值可以认为是可靠的。除了新颖的LWR，我们还提供了一些物种估计，其中包括尚未参与任何LWR研究的新TLmax。
