Length-weight relationships of 4 coral-reef fish species regularly encountered in artisanal coastal fisheries across 5 atolls of the Gilbert Islands, Kiribati, were obtained. The data were collected through creel surveys undertaken randomly over a period of 20–100 days each year between 2013 and 2020. The main fishing methods used were gillnetting (minimum legal mesh size of 63.5 mm), handlining and spearfishing. Fish were weighed using a digital scale calibrated to ±1–5 g and measured on a flat one-meter ruler delineated in 5 mm increments. Parameters a and b extracted from the general form of the equation describing the relationship between length and weight (W = aL^b), associated 95% Confidence Intervals (CI) and correlation coefficients (r²) are presented here.

吉尔伯特群岛沿海手工渔业中遇到的 4 种珊瑚礁鱼类的长度-重量关系

获得了基里巴斯吉尔伯特群岛 5 个环礁的手工沿海渔业中经常遇到的 4 种珊瑚礁鱼类的长度-重量关系。数据是通过 2013 年至 2020 年期间每年 20-100 天随机进行的筒子架调查收集的。使用的主要捕鱼方法是刺网（最小合法网目尺寸为 63.5 毫米）、手钓和鱼叉捕鱼。使用校准为 ±1-5 克的数字秤对鱼进行称重，并在以 5 毫米增量划定的一米平尺上测量。从描述长度和重量之间关系的方程的一般形式中提取的参数a和b ( W  =  a L ^b)，此处显示了相关的 95% 置信区间 (CI) 和相关系数 ( r ² )。
