Abstract

The length–weight relationship (LWR) in fish is an important tool because it allows understanding aspects such as growth assessment, body condition, and biomass estimation. The aim of this study was to determine the LWR of food fish species from the Amazonian plain of the Putumayo River caught by artisanal fisheries to be sold in the town of Puerto Leguízamo between 2018 and 2023. More than 19,000 individuals of 31 species were registered. Each fish was taxonomically identified at the species level, recording its standard length (cm) and weight (g). Searches in FishBase revealed that six species lack referenced data, twenty five are not reported for the Putumayo Basin, and five are in the vulnerable category, according to the International Union for Conservation of Nature (IUCN). The relationship data calculated in this study are the first publications for these species in this region of the Amazon Basin. Knowledge of these biometric data and their relationships is relevant for managing and conserving fish and fisheries.

哥伦比亚普图马约河上游食用鱼类的长度-重量关系

鱼类的长重关系（LWR）是一个重要的工具，因为它可以理解诸如生长评估，身体状况和生物量估算等方面。本研究的目的是确定2018年至2023年期间在Puerto Leguízamo镇出售的手工渔业在普图马约河亚马逊平原捕获的食用鱼物种的LWR。共有31个物种，19,000多只。在物种水平上对每条鱼进行分类鉴定，记录其标准长度（cm）和重量(g)。根据国际自然保护联盟（IUCN）的数据，在FishBase上的搜索显示，有6个物种缺乏参考数据，25个物种没有报告，5个物种属于易危类别。本研究计算的关系数据是亚马逊流域该地区首次发表的这些物种的关系数据。了解这些生物特征数据及其相互关系对鱼类和渔业的管理和保护至关重要。
