Hubungan panjang berat dan faktor kondisi ikan sepat (Trichogaster pectoralis) di Perairan Rawa Desa Lakea Dua Kabupaten Buol Sulawesi Tengah

Abstract

This study aims to determine the relationship between length and weight and condition factors of Trichopodus trichopterus in the waters of Rawa, Lakea Dua Village, Buol Regency, Central Sulawesi. The research was carried out for 2 months and took place in the swamps of Lakea Dua Village, Buol Regency, Central Sulawesi. The fish collected were measured based on the total length using a ruler in cm (1 mm accuracy), while the fish weight was measured using a digital scale with units of grams (0.01 gram accuracy). The test parameters observed included analysis of length and weight, relative weight, fulcon condition factor, and relative condition factor. The results showed that there were 53 Trichopodus trichopterus collected in the swamps of Lakea Dua Village, Buol Regency. The length ranges from 10-18 cm with an average length of 14.43±2.39 cm. Fish weight ranged from 14.50-155.30 g with an average weight of 51.33±25.83 g. The growth pattern is negative allometric. The relative weight shows a value of 102.63±21.40, meaning that the source of feed is abundant in the Trichopodus pectoralis environment and the condition is healthy. The Fulcon condition factor value is 1.61±0.55 and the relative condition factor is 1.04±0.33, meaning that the condition factor value is below 3. This shows the cheek-shaped fish. Keywords: condition factor; length weight; Trichogaster pectoralis

THE LENGTH-WEIGHT RELATIONSHIP OF Butis sp. IN THE TAMBUN RIVER, TOLITOLI DISTRICT, CENTRAL SULAWESI

“…Sampel ikan uji diperoleh dari hasil tangkapan menggunakan jaring mesh 1 mm yang berukuran 100 cm x 50 cm. Ikan yang tertangkap diukur berdasarkan panjang total menggunakan penggaris satuan cm (ketelitian 1 mm), sedangkan berat ikan diukur menggunakan timbangan digital dengan satuan gram (ketelitian 0,01 gram) (Laheng et al, 2022).…”

“…di Sungai Tambun diamati untuk mengetahui kelayakan lingkungan hidupnya dalam mendukung kelangsungan hidup Butis sp.. Parameter yang diamati yaitu kedalaman air, warna air, substrat dan kualitas air (suhu dan pH air). Pengamatan kondisi habitat diamati dengan cara in situ (Laheng et al, 2022). Perbedaan panjang ikan dan bobot ikan butis disebabkan jenis spesies ikan dan lokasi perairan yang berbeda.…”
