ABSTRAK

Penelitian ini bertujuan untuk mengkaji keanekaragaman dan fekunditas ikan rawa di Desa Pimping, Kecamatan Lampihong, Kabupaten Balangan, Provinsi Kalimantan Selatan. Kawasan rawa ini merupakan ekosistem perairan yang memiliki nilai ekologis dan ekonomis penting bagi masyarakat sekitar. Pengambilan data dilakukan pada tiga stasiun berdasarkan karakteristik lokasi. Hasil penelitian menunjukkan terdapat 7 spesies ikan dari 5 famili yang tertangkap, di antaranya Anabas testudineus (papuyu), Trichopodus trichopterus (sepat rawa), Trichopodus pectoralis (sepat siam), Helostoma temminckii (biawan), dan Channa striata (haruan). Fekunditas tertinggi ditemukan pada ikan biawan dengan rerata 29.842 butir telur di Stasiun 1, sedangkan nilai fekunditas terendah ditemukan pada sepat siam. Tingkat kematangan gonad (TKG) ikan menunjukkan variasi dari TKG I hingga TKG V. Hubungan panjang dan berat ikan menunjukkan hasil alometrik. Kualitas air di ketiga stasiun menunjukkan suhu berkisar 28,2–30,8 °C, pH 5,46–7,13, dan DO (Dissolved Oxygen) antara 1,3–2 mg/L. Penelitian ini memberikan informasi penting sebagai dasar pengelolaan dan pelestarian perikanan rawa secara berkelanjutan di wilayah Desa Pimping.

ABSTRACT

This study aims to assess the diversity and fecundity of swamp fish in Pimping Village, Lampihong District, Balangan Regency, South Kalimantan Province. This swamp area is an aquatic ecosystem that has important ecological and economic values for the surrounding community. Data were collected at three stations based on location characteristics. The results showed that 7 fish species from 5 families were caught, including Anabas testudineus (papuyu), Trichopodus trichopterus (swamp sepat), Trichopodus pectoralis (Siamese sepat), Helostoma temminckii (biawan), and Channa striata (haruan). The highest fecundity was found in biawan fish with an average of 29,842 eggs at Station 1, while the lowest fecundity value was found in Siamese sepat. The level of gonad maturity (TKG) of fish showed variation from TKG I to TKG V. Fish length and weight relationship showed allometric results. Water quality at the three stations showed temperatures ranging from 28.2-30.8°C, pH 5.46-7.13, and DO (Dissolved Oxygen) between 1.3-2 mg/L. This study provides important information as a basis for sustainable management and conservation of swamp fisheries in the Pimping Village area.
