Abstract

Skipjack tuna (Katsuwonus pelamis) is a large pelagic fish that seeks prey using the sense of sight, so the color of the hook used must be able to attract the attention of skipjack to eat the hook. The purpose of this research is to determine the effect of hook color on pole and line catches. The colors of the hook used are red, green and silver. The analysis used to see differences in skipjack catches based on hook color used two analyzes, namely comparative descriptive and statistical. Comparative descriptive analysis was carried out on the composition of pole and line catches. Statistical test using completely randomized design (CRD). The results showed that the hooks that produced the most skipjack tuna were red with 1785 fish or 57% of the total catch, then green with 830 fish (26%) and silver with 513 (17%) catches. Based on the CRD ANOVA statistical test, the average difference in catches based on hook color was significantly different with a significance value less than 0.05 (0.00<0.05), which means the catches of the 3 hook colors were significantly different. From the catch data, the hook color that gets the most catches is the red hook.

Abstract

Tuna and skipjack are large pelagic fish that have high economic value and have a very wide export market. The need for and the high market demand for tuna and skipjack causes the intensity of catching this fish to increase. To ensure that the potential of these fish resources remains sustainable, it is necessary to properly manage fisheries.The purpose of this study was to examine several aspects of biology, aspects of capture fisheries, aspects of utilization and management of yellow fin tuna and skipjack tuna. Data collection for yellowfin tuna was focused on one location, namely PPS Bungus, while data collection for skipjack tuna was focused on 4 location points, namely PPS Bungus, PPP Carocok Terusan, PPI Kambang and PPI Tiku. Productivity and cultivation levels of yellowfin tuna in West Sumatra have tended to decline in the past 4 years (2017-2020). Skipjack tuna in the West Sumatra region caught by boat charters was indicated to be overfishing, while skipjack tuna caught by troll showed the fish caught had not spawned yet. The productivity of skipjack tuna has fluctuated over the past 5 years (2016-2020).
