摘要
在肯达里(FMA 714)水域中占主导地位的小型远洋资源是鲭鱼(Decapterus macarellus)和印度鲭鱼(Rastrelliger kanagurta)。在这些水域捕鱼使用迷你围网,两种鱼类的产量已达到总允许捕获量的38.2%。由于集约使用,管理需要保护资源。本研究的目的是通过首次捕获长度(Lc)和首次成熟长度(Lm)的比较和产卵季节的预测来确定合适的大小。数据收集工作每月由研究人员进行,并由统计员协助。结果表明,该鱼的鱼鳞大小在17.5 ~ 30.5 cm FL之间(n = 3207尾)。印度鲭鱼的大小在18.5 - 26.5厘米英尺之间(n = 2556)。两种鱼的初次捕获长度均大于初次成熟时的大小(Lm> Lc),鲭鱼的适宜大小为23 cm FL,印度鲭鱼为22 cm FL。对5 - 8月产卵期的预测可作为产卵期封区的依据。关键词:鲭鱼网,印度鲭鱼,迷你围网,合适尺寸,FMA 714

The small pelagic resources in the waters of Kendari (FMA 714) that are dominant are mackerel scad (Decapterus macarellus) and Indian mackerel (Rastrelliger kanagurta). Fishing in these waters uses a mini purse seine, with the production of 2 species of fish has reached 38.2% of the total allowed catch FMA 714. Because of intensive use, management needed to preserve resources. The purpose of this study is to determine the decent size based on a comparison of length of the first capture (Lc) and the length of first mature (Lm), and prediction of spawning season. Data collection was conducted by researchers and assisted by enumerators monthly. The results showed that the size of the mackerel scad in between 17.5 - 30.5 cm FL (n = 3207 tails). The size of the Indian mackerel found between 18.5 - 26.5 cm FL (n = 2556). The length at first captured of both species was larger than the size at first matured (Lm> Lc) so that the decent size is 23 cm FL for mackerel scad and 22 cm FL for Indian mackerel. The prediction of the spawning season in May-August can be the basis for closing the area during the spawning season.
