ABSTRACT
Wulan River and Estuarine in Demak have a diversity of species, such as shrimp. Wulan river exploited by fishermen to catch fish, shrimp, shellfish and others. To find out the condition of the juvenile shrimp’s population in the Wulan river and estuary, has been studied by using a trap. The study aims to find out the type of juvenile shrimps that were trapped, the growth pattern, and the effect of the location.Juvenile shrimps sampling was performed in two stations, one on the river and one other on the estuary which consist of three points in period I until period IV. Catches resulted in the trap was stored in sample bottles and was soaked in 5% formalin. It was obtained that the juvenile shrimps type collected was from MetapenaeusdanPenaeus genus. Total numbers of juvenile shrimps obtained in the river was less than in the estuary.The numbers of Metapenaeus genus trapped was more than Penaeus genus. The overall numbers of juvenile shrimps caught was 103 juveniles. The growth pattern ofjuvenile shrimps was negatively allometric.
