Abstract

Shrimp as one of potential commodity which has a high protein and savory flavor of meat is highly favored by the people in the country and abroad. The catch activity of the Metapenaeopsis mogiensis shrimp by the fisherman in Pusong Lama, Lhoksemawe has long been a livelihood. However, if the shrimp catching activity was carried out continuously without any restrictions, it can threaten the sustainability of the shrimp. The purpose of this study was to determine the lenght-weight relationship of shrimp caught in the waters of Aceh Utara, Indonesia. This research was expected to provide additional information on the existence of Metapenaeus mogiensis shrimp and future sustainable resource management for farmers. The research method used was a simple random withdrawal method by taking shrimp samples randomly from a basket of fishermen's catch in one sail. A total of 10% shrimp samples of the total catch of fishermen was taken, then length was measured and weighed. Sampling was carried out in July2019 at TPI Pusong lama, Lhoksemawe. The length of carapace of male shrimp ranges from 14.8 mm to 22.2 mm and females 13.9 mm to 22.1 mm.The weight of male shrimp ranges from 2.17 grams to 6.73 grams and the weight of female shrimp ranges from 2.01 grams to 5.83 grams. Growth patterns found in both males and femalesshowed allometric negatives and the ratio of sex was 1.5: 1 (male:female).
