Abstract

Salah satu komoditas penting perikanan tangkap di Sulawesi Tenggara, khususnya perikanan skala kecil adalah rajungan dengan menggunakan alat tangkap bubu. Usaha penangkapan dikatakan berhasil apabila mendapatkan keuntungan yang maksimal bagi pelaku usahanya. Penggunaan jenis umpan yang berbeda pada alat tangkap bubu menghasilkan hasil tangkapan yang berbeda. Tujuan penelitian ini adalah untuk menganalisa aspek finansial yang mencakup biaya, pendapatan, keuntungan, dan tingkat kelayakan finansial usaha penangkapan rajungan menggunakan umpan berbeda, yaitu ikan peperek dan ikan teri. Metode yang digunakan dalam penelitian ini adalah metode survei yaitu dengan cara peninjauan, pengamatan serta pengambilan data informasi secara langsung di lapangan. Hasil penelitian menunjukkan bahwa biaya tidak tetap yang dikeluarkan setiap tahunnya memiliki jumlah yang lebih besar dibandingkan dengan biaya tetap. Penerimaan terbesar usaha penangkapan rajungan adalah dengan menggunakan umpan ikan peperek dengan keuntungan yang didapat sudah dapat menutupi biaya-biaya yang dikeluarkan. Usaha penangkapan rajungan menggunakan ikan peperek dikatakan layak dan menguntungkan yang terlihat dari nilai NPV, IRR, dan B/C Ratio dengan pengembalian modal masuk kedalam kategori pengembalian modal sedang. Sedangkan dengan menggunakan umpan ikan teri mengalami kerugian, dimana penerimaan yang didapat tidak dapat menutupi biaya-biaya yang dikeluarkan.

Abstract

Meretrix meretrix is a degraded resource in Kendari Bay waters, but its reproductive pattern is not fully known.. This study aims to determine the level of gonad maturity, gonadal maturity index, fecundity and the size of the first gonad maturity of M. meretrix at the Kambu River estuary, Kendari Bay, Southeast Sulawesi. This research was carried out at the Kambu River estuary for 6 months from August 2021-January 2022. These clams were taken randomly representing all size classes as many as 300 birds during the study. M. meretrix were observed for gonad color and gonad development microscopically, then the length and weight of the gonads were measured using a caliper and analytical balance with an accuracy of 0.5 mm and 0.0001g, respectively. The results showed that the development of male and female gonads was relatively simultaneous, which was dominated by mature gonads (III-IV) in each month of observation. TKG I-V was found in every month of observation. The gonad maturity index of males and females were 4.92-6.00 and 5.53-6.32, respectively. The fecundity of M. meretrix ranged from 4882-85677 grains. The first mature size of the gonads of male and female M. meretrix is 20 mm.

Abstract

Inland waters within Fisheries Management Area of the Republic of Indonesia for Inland Waters (WPPNRI PD) play a crucial role in supporting biodiversity and sustainable fisheries resources. Halmahera Island, which is part of WPPNRI PD 413, is known for its high freshwater biodiversity, including the river prawn Macrobrachium lar. This study examined the abundance and habitat characteristics of M. lar in inland waters of Halmahera Island. Field surveys were conducted at three river systems representing western, central, and southern Halmahera. The highest relative abundance observed in southern Halmahera. The results indicate that variations in relative abundance are closely associated with habitat heterogeneity. Southern Halmahera was characterized by higher elevation, mixed sandy–rocky substrates, stable dissolved oxygen, suitable water temperature, and relatively dense tree canopy closure. These conditions likely provide favorable microhabitats, thermal stability, and reduced light intensity for M. lar. Overall, the findings demonstrate that the distribution and abundance of M. lar are strongly influenced by the integrated effects of physical, chemical, and structural habitat features. Maintaining the integrity of river habitats, particularly tree canopy cover along river corridors, is essential for sustaining freshwater prawn populations and supporting sustainable inland fisheries management within WPPNRI PD 413, Halmahera Island.
