Abstract

Giant snakehead yang juga dikenal dengan sebutan Toman merupakan ikan dengan cita rasa dan bernilai ekonomis. Penelitian ini bertujuan untuk mengetahui keragaman genetik populasi C. micropeltes di Taman Nasional Sebangau (TNS), Kalimantan Tengah menggunakan analisis molekuler dengan pendanda genetic Random Amplified Polymorphic DNA (RAPD). Primer yang digunakan pada penelitian ini yaitu OPE-07, OPD-03 dan OPG-10. Hasil menunjukkan bahwa persentase polimorfisme di perairan TNS tergolong rendah (43,1818%) dan heterozigositas juga tidak jauh berbeda yaitu 0,2323 dan 0,2067. Berdasarkan pada uji berpasangan Fst, populasi C. micropeltes di perairan TNS tidak berbeda nyata (P>0,05). Sehingga dapat disimpulkan bahwa C. micropeltes di perairan SNP populasi sungai Sebangau maupun Katingan tidak terdapat perbedaan keragaman genetik. Secara genetik, C. micropeltes di perairan SNP memiliki keanekaragaman relatif rendah dan kemampuan adaptasi rendah.

Abstract

Squid belongs to the phylum Mollusca, specifically the Cephalopoda group (soft-bodied animals) which is one of Indonesia's fisheries resources. One of the regions abundant in squid fisheries resources is the waters of Majene, West Sulawesi Province. This research aims to determine the distribution of the captured squid's size structure and growth patterns in the waters of Majene. Squid sampling was conducted in July–August 2023. The sampling procedure involved randomly selecting squid catches from fishermen in the waters of Majene with a sampling frequency of once a month, resulting in a total of 102 specimens of Loligo sp. squid, consisting of 82 males and 20 females. Overall, the range of mantle length obtained for Loligo sp. squid was 90–180 mm, with a weight range of 26.08–306.19 g. The majority of male squid caught during the study had a mantle length in the range of 127–138 mm, while female squid had a mantle length range of 115–126 mm. Based on statistical analysis, the growth pattern of combined and male Loligo sp. squid in the waters of Majene exhibited negative allometric growth, meaning that weight increase was more dominant than length increase. In contrast, female squid exhibited positive allometric growth, indicating that weight increase was more dominant than length increase.
