ABSTRACT
Kendal is one area which is on the north coast of Java Sea. The biggest fish auction place in Kendal Regency is Tawang Fish Auction (TPI Tawang). One of kind of demersal fish that caught in TPI Tawang is Croackers Fish. Biological aspect is needed to manage the resources of Croackers Fish. The porpose of this study is to found out the biological aspects of Croackers Fish Landed in Tawang Fish Auction Market. The research did in Juny 2016. The method used in this research is survey method. The sampling was taken by using Purposive sampling. From the research on 390 fish. the length size of Croackers Fish range from 10,5 cm – 20,9 cm.
