Spatial and temporal variation of sea surface temperature and chlorophyll-a on the mackerel fish (Scomberomorus commerson) distribution using aqua modis satellite in naukerjerai district, merauke regency

Abstract

Remote sensing is a technique that can be applied for observing oceanographic paramaters such as content of sea surface temperature and chlorophyll-a. The study aims to analyze the parameters of Sea Surface Temperature and Chlorophyll-a by using Aqua Modis Satellite to see the spatial and temporal distribution of the two paramaters on the distribution of CPUE of Mackerel (Scomberomorus commerson).Conducted for 2 months from May-June 2019 this study was held in the waters area of Naukenjerai District, Merauke Regency. The results showed the concentration of sea surface temperature in May was warmer in the range of 26.56 – 28.42 °C compared to June, where the temperature was cooler in the range of 25.43 – 26.94 °C. Meanwhile the concentration of chlorophyll-a in May was seen to be low around 0.3-1.73 mg/m3 which compared to June the concentration was relatively high around 1.45-2.36 mg/m3. The highest distribution of CPUE of Mackerel was found in June, which was 89 kg and the lowest CPUE Mackerel in May was around 22 kg. Therefore in June there is a great potential for capturing Mackerel.
