Abstract

Aceh fishermen in Ocean Fishing Port Kutaraja Banda Aceh generally carry out fishing operations around Aceh North waters which have abundant and diverse biological potential. Catches in Aceh North waters are still heavily influenced by several natural factors that often occur in certain seasons, one of which is the factor of Sea Surface Temperature (SST) based on this research about the effect of SST on purse seine catches based in Kutaraja Banda Aceh Ocean Fishery Port. This study aims to determine the catches of purse seine fishermen in Kutaraja Ocean Fishery Port to know the SST distribution, and to determine the effect of SST on purse seine catches based in Kutaraja Banda Aceh Ocean Fishery Port. This research was conducted in November 2019 at Kutaraja Ocean Fishery Port. Data analysis used in this study is purse seine catch data obtained from UPTD from 2015-2019 tabulated in tabular and graphical format, SST distribution obtained from Aqua-MODIS satellites from 2015-2019 using SeaDas software and analysis used to see the effect of SST on catch is using linear regression analysis. The conclusian is based on the results of studies on how ocean SPL affect the fish catches using purse seine with the highest vessel size of 11-20 GT in 2018 with a total of 2,499,634 kg while the lowest catch in 2016 with a total of 1,460,220 kg. SST distribution found in Aceh North waters shows that the highest temperature occurred in 2015 which was 30.24oC while the lowest occurred in 2016 which was 29.04oC. From linear regression analysis results showed that SST in Aceh North waters showed a coefficient of determination (R²) of 0.2279. This value can give a picture that the SST parameters contribute to fish catches of 22.79% and the rest is influenced by other oceanographic factors. While the correlation coefficient (r) of 0.477 means that this condition can indicate sufficient correlation have a positive

Highlights

Aceh Province is located between 01 ̊ 58' 37.2” – 06 ̊ 04' 33.6” North Latitude and 94 ̊ 57' 57.6” – 98 ̊ 17' 13.2” East Longitude with an average altitude of 125 meters above sea level
Acehnese fishermen in Ocean Fishery Port Kutaraja generally carry out fishing operations around the Aceh northern waters
Sea Surface Temperature (SST) content obtained in Aceh northern waters shows that the sea surface temperature in 2016 to 2019 started from the lowest temperature of 29.04 °C occurred in 2016 and reached the highest temperature of 30.24 °C occurred in 2015 with an average value of the average sea surface temperature of 29.86 °C (Figure 3)

Summary

Introduction

Aceh Province is located between 01 ̊ 58' 37.2” – 06 ̊ 04' 33.6” North Latitude and 94 ̊ 57' 57.6” – 98 ̊ 17' 13.2” East Longitude with an average altitude of 125 meters above sea level. Aceh province boundaries from the north and east are bordered by the Malacca Strait. In the south with the province of North Sumatra and in the west with the Indonesian Ocean [1]. Acehnese fishermen in Ocean Fishery Port Kutaraja generally carry out fishing operations around the Aceh northern waters. The Aceh northern waters are used as fishing operations areas (Fishing ground). The water was often used for fishing and was a migration line, promoting the fishing economy of Aceh [2, 3]
