The relationship between shrimps production and mangrove ecosystem in Indramayu Regency

Abstract

Shrimp is one of the agricultural commodities which has high economic value with global and increasing market value abroad. Thus, Shrimp production continues to increase. Shrimp production in Indramayu Regency in 2017 was 191,919.41 tons. This makes Indramayu Regency the largest producer of shrimp in West Java (BPS, 2017). Meanwhile, Mangrove is an area that has a high contribution. Mangrove ecosystems have an association with pond productivity. This study aims to analyze the productivity value of shrimp in Indramayu Regency and its effect on the mangrove ecosystem in Indramayu Regency in that particular area. The method that is used to change identify mangrove forests is Landsat 8 image then continued with composite band 564 and NDVI (Normalized Difference Vegetationation Index) with a distance of 1 Km, 2 Km, and 3 Km from the mangroves. Furthermore, the result of the interviews is used to find out the value of shrimp productivity. Analysis of data is calculated through regression methods to see the–relation proximity between shrimp productivity and mangroves. The regression result between the distance of mangroves and productivity yields with the value of R Square equals 71.7%. This result indicates a positive link between shrimp productivity and mangrove ecosystem.
