This study describes the length–weight relationships (LWR) for 18 species of coral reef fish from the northern Line Islands, a geographically remote area of the central Pacific (3.48°N 158.80°W). Specimens were collected across multiple field campaigns (on average: 3–5 days per island, two islands per year) from 2006 to 2011 using three-prong spears, spearguns, handlines, fishing poles, and fish anesthetic with hand nets (1 mm mesh), and measurements of total length (TL: 0.1 cm precision) and total weight (W: 0.01 g precision) were taken. The LWR were calculated using the linear regression of the log-transformed length and weight data. New LWR are reported for 13 common species from the central tropical Pacific, as well as LWR across new maximum total lengths for five species, thus expanding the observed size range for these scaling relationships.

中太平洋 18 种珊瑚礁鱼类的长重关系

本研究描述了来自中太平洋（3.48°N 158.80°W）地理偏远地区北部莱恩群岛的 18 种珊瑚礁鱼的长重关系（LWR）。从 2006 年到 2011 年，使用三叉矛、鱼枪、手绳、鱼竿和带手网（1 毫米网眼）的鱼麻醉剂，在多次野外活动（平均：每个岛屿 3-5 天，每年两个岛屿）中收集了样本），以及总长度（TL：0.1 厘米精度）和总重量（W: 0.01 g 精度）。使用对数转换的长度和重量数据的线性回归计算 LWR。报告了来自中部热带太平洋的 13 个常见物种的新 LWR，以及 5 个物种的新最大总长度的 LWR，从而扩大了这些比例关系的观察到的大小范围。
