Abstract
Shrimp as one of potential commodity which hasahigh protein and savory flavor of meat is highly favored by the people in the country and abroad. The catch activity of theMetapenaeopsis mogiensisshrimp 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 ofMetapenaeus mogiensisshrimp 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).
Highlights
Indonesia has many edible fish and crustaceans [1, 2,16] and Aceh is one province located at the western tip of Indonesia
The numbers of Metapenaeopsis mogiensis caught during the study were 100, 60 male shrimp and 40 female shrimp
The results showed the correlation coefficient (r) of male and female Metapenaeuopsis mogiensis shrimp 0.95 and 0.94 which showed that the relationship between weight gain of shrimp with length increase indicated a strong relationship (Figure 1)
Summary
Indonesia has many edible fish and crustaceans [1, 2,16] and Aceh is one province located at the western tip of Indonesia. Along the East Coast of Aceh Province has a variety of diversity in the marine crustaceans sector. Metapenaeopsis mogiensis shrimp is one of the shrimp that has important economic value in the waters of North Aceh, Lhokseumawe. Excessive use of fishery resources can threaten the sustainability of these Metapenaeopsis mogiensis shrimp resources. Shrimp are known as important commodities from the fisheries sector, because they have high nutritional value [1,3]. Shrimp fishing as a target encourages increased sustainable fishing efforts. This is caused by increased market demand for shrimp. This research is expected to provide additional information about the existence of Metapenaeopsis mogiensis shrimp and sustainable management of crustacean fisheries resources for farmers
