Abstract

This study aims to examine the effect of sea surface temperature on the skipjack tuna catch (Katsuwonus pelamis) in the waters of the Bali Strait. The waters of the Bali strait are selected by the authors because the waters of the Bali strait have the potential of catching tuna fish is high. The research is measured by using regression polynomial method of order 2. With the results of this study found from the sea surface temperature data in the results of the average - the average year 2011 - 2015 where the highest value is in March at 30.240C and the lowest in September of 25.870C. For skipjack catch data in 2011 - 2015 where the lowest weight in June was 4. 590 kg, while the highest weight in July was 61,367 kg, and beside that the result of regression 2nd polynomial regression was obtained with R = - 0.60 which has a strong meaning is inversely proportional or in other words sea surface temperature does not affect the catching of skipjack tuna in the waters of bali strait because in addition to sea surface temperature factors other indicators such as chlorophyll, depth, and oceanographic factors also affect the catch skipjack tuna in the waters of the bali strait.
海水温度对巴厘岛海峡中鲣鱼的渔获有影响
本研究旨在探讨海水表面温度对巴厘岛海峡海域鲣鱼捕捞量的影响。作者之所以选择巴厘岛海峡水域,是因为巴厘岛海峡水域捕捞金枪鱼的潜力很大。研究结果采用2阶回归多项式方法进行测量。根据本研究的结果,从海表温度数据中发现了2011 - 2015年的平均值,其中3月份的最高值为30.240℃,9月份的最低值为25.870℃。对于2011 - 2015年的鲣鱼捕捞数据,6月份的最低体重为4。此外,回归第二次多项式回归的结果R = - 0.60,具有较强的反比意义,即海面温度不影响巴厘岛海峡水域鲣鱼的捕捞,因为除了海面温度因素外,叶绿素、深度、海洋学因素也会影响巴厘岛海峡水域的鲣鱼捕捞。
