Excessive exploitation of fish resources with the use of fishing gear that is not selective and not eco-friendly will have an impact on the sustainability of capture fisheries, and cause damage to fish resources and marine ecosystems. The mini purse seine is a fishing gear that is most widely used by fishermen in the sea of the north coast of Java. Research was undertaken the Nusantara Fisheries Port (PPN), Pekalongan. The purpose of this research is to analyze the level of eco friendliness of mini purse seine fishing based on the main catch, which is (Decapterus spp.). The research method used a survey method at PPN Pekalongan and follows the operation of 3 units of mini purse seine working the fishing ground on the North Coast of Central Java, in January-February 2018. Data taken included total catches, catch composition, diversity index and the size of the fork length. Data analysis used the proportion of the main catch and by-catch, as well as the proportion of fish worth catching and not catching. The results showed that the mini purse seine fishing gear caught 6 species with a total catch of 35,633 with a weight of 4,600 kg. The main catch is 51%, compared to 49% by-catch. The length of the main catch fish worth catching is 46% of all fish measured. Diversity index value is 1.42 (high diversity), based on a research mini purse seine operated in the the Java Sea. The results of our work indicate that mini purse seine fishing is not eco friendly - as seen from the criteria of catch composition.
