Abstract. Indarjo A, Salim G, Nugraeni CD, Zein M, Ransangan J, Prakoso LY, Suhirwan, Anggoro S. 2021. Length-weight relationship, sex ratio, mortality and growth condition of natural stock of Macrobrachium rosenbergii from the estuarine systems of North Kalimantan, Indonesia. Biodiversitas 22: 846-857. Giant prawns (Macrobrachium rosenbergii) in North Kalimantan Province, Indonesia are commonly found inhabiting estuarine areas in Salimbatu Village (Bulungan District), Tepian Village (Nunukan District) and Buong Baru and Sesayap Villages (Tana Tidung District). The present study was conducted to analyze the relationship between length and weight, sex ratio, mortality, and growth condition index of the naturally occurring giant prawns in three districts namely Bulungan, Nunukan, and Tana Tidung in the North Kalimantan Province, Indonesia. The samplings were carried out for a period of seven months beginning April to November 2020. The results revealed that the giant prawns in Buong Baru Village, Sesayap Village, and Salimbatu Village were characterized to have negative allometric growth patterns. Interestingly, the male giant prawns in Tepian Village were observed to exhibit positive allometric growth pattern. The ratio sex analysis of the giant prawns in the four villages indicated that female prawns were more than male. In terms of size distribution, Salimbatu Village exhibited 60.1% of prawns measured at 14.02-17.74cm (size range of 10.3-47.5 cm). In Tepian Village, 32.9% of the prawns were observed to measure between 11.20-12.80 cm (size range of 8.0-24.0 cm). In Buong Baru Village, it was observed 18.5% of the prawns measured 22.0-25.5 cm and 29.0-32.5 cm (size range of 15.0-50.0 cm), respectively. Finally, 28.3% of the prawns in Sesayap Village was observed to measure at 12.19-14.02 cm from the overall size distribution between 6.7-25.0 cm. Relative condition factor of giant prawns found in the waters of Salimbatu Village, Tepian Village, and Buong Baru Village waters and Sesayap Village waters was characterized by thin body shape. The maximum length of male prawns was higher than female prawns in Salimbatu Village, Desa Tepian and Sesayap Village, except in Buong Baru Village where female was longer than male. The exploitation rate and fishing mortalities of prawns were higher in Buong Baru Village, Tana Tidung District. Giant prawn fishery contributes to the socio-economic development of the people in North Kalimantan. Hence, sustainable fishery management of this species, particularly in Buong Baru Village is urgently needed so that it can continue to provide livelihoods to the fishermen in the area.

Abstract. Asriyana A, Irawati N, Halili H. 2020. Length-weight relationships and ponderal index of three reef fish (Teleostei: Labridae) off the Tanjung Tiram coast, Southeast Sulawesi, Indonesia. Biodiversitas 21: 1279-1286. Parameters of length-weight relationship and ponderal index were estimated for first time for three reef fish (Labridae), Cheilinus trilobatus, Cheilinus chlorourus, and Choerodon anchorago, off the Tanjung Tiram coast, Indonesia. A total of 292 specimens (C. trilobatus 146 specimens; C. chlorourus 100 specimens; C. anchorago 46 specimens) were collected monthly in experimental gillnets in coral reefs and seagrass beds from January to June 2018. The length-weight relationship and ponderal index were calculated for each species. C. trilobatus showed total length and weight of 9.0-17.2 cm and 12.33-78.79 g, respectively, while C. chlorourus was 8.5-17.5 cm and 10.41-100.21 g, and C. anchorago 9.0-27.0 cm and 18.51-414.00 g. C. trilobatus showed negative allometric growth, while C. chlorourus and C. anchorago had isometric growth. The length-weight relationship of C. trilobatus followed the linear equation of W=0.10TL2.35, while C. chlorourus and C. anchorago fit to W=0.03TL2.83; W=0.03TL2.91 respectively. The highest ponderal index occurred in May for C. trilobatus and in June for C. chlorourus and C. anchorago indicating a peak of the spawning season. The study results could be used as baseline information for future fisheries management of the area.

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).
