其他摘要:ABSTRACT Grouper Epinephelus sp. farming activities in Lampung Bay is limited to an area of 77 hectares, while areas that are potential to be used for grouper farming are still very wide. Therefore, this study aimed to assess the suitability of Lampung Bay waters for grouper farming activities. The study was conducted in 20 stations with ecological preference considerations. The parameters observed were physicochemical (water depth, temperature, water transparency, the load of suspended solids, pH, dissolved oxygen, salinity, nitrate, and phosphate) and biological parameters (phytoplankton abundance and chlorophyll-a concentration). After the data were completely obtained, the data were processed into suitability matrix resulting in scores that will be grouped into four classes, namely S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N (not suitable). The geostatistical model was used to perform the earth’s surface mapping based on biotic and abiotic parameters that were analyzed. Based on the results of the analysis in this study, the conditions of Lampung Bay waters were suitable for grouper farming activities. Marine area that could be used for grouper farming was 33,847.12 hectares (S1: 15,712.6 ha, S2: 13,294.7 ha and S3: 4,209.82 ha) in the area around Puhawang Island, Kelagian Island, Maitem Island, Tegal Island to Hurun Bay.
