Abstrak

Jenis ikan rawa seperti channidae mempunyai peluang besar untuk dikembangkan. Pertimbangan harga ekonomis yang tinggi, ikan gabus (Channa striata)jugasebagai sumber makanan dan mempunyai kandungan nutrisi yang tinggi. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian dosis glukosa terhadap daya tetas telur ikan gabus. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan dengan menggunakan kadar glukosa yaitu A (0,1 ml), B (0,2 ml), C (0,3 ml), D (kontrol). Parameter yang diamati adalah Pertumbuhan Diameter Telur, derajat penetasan, waktu penetasan dan parameter pendukung kualitas air. Hasil penelitian ini didapatkan rerata diameter telur ikan gabus tertinggi pada perlakuan C (1723 µm) kemudian disusul perlakuan B (1524 µm), A (1419 µm) dan terkecil pada perlakuan D (1364 µm). Rerata derajat penetasan telur ikan gabus tertinggi pada perlakuan C (92%) kemudian disusul perlakuan B (85%), A (80%) dan paling rendah pada perlakuan D (67%). Hasil rerata waktu penetasan telur ikan gabus tercepat pada perlakuan C (1.389 menit) disusul perlakuan B (1.439), A (80%) waktu terlama perlakuan D (1.625 menit). Hasil uji ANOVA pada penelitian ini seluruhnya berpengaruh nyata dilanjutkan uji lanjutan BNJ dan Duncan, hasil yang di peroleh berpengaruh nyata pada daya tetas telur ikan gabus.

Kata Kunci: ikan gabus, glukosa, daya tetas.

Abstract

Swamp fish species such as channidae have a great opportunity to be developed. Considering the high economic price, cork fish (Channa striata) is also a food source and has a high nutritional content. The purpose of this study was to determine the effect of glucose dosing on the hatchability of cork fish eggs. This study used a completely randomized design (CRD) with 4 treatments and 3 replicates using glucose levels namely A (0.1 ml), B (0.2 ml), C (0.3 ml), D (control). The parameters observed were Egg Diameter Growth, hatching degree, hatching time and supporting parameters of water quality. The results of this study obtained the highest mean diameter of cork fish eggs in treatment C (1723 µm) followed by treatment B (1524 µm), A (1419 µm) and the smallest in treatment D (1364 µm). The average degree of hatching of cork fish eggs was highest in treatment C (92%) followed by treatment B (85%), A (80%) and the lowest in treatment D (67%). The average hatching time of the fastest cork fish eggs in treatment C (1,389 minutes) followed by treatment B (1,439), A (80%) and the longest time in treatment D (1,625 minutes). The results of the ANOVA test in this study all had a significant effect followed by the BNJ and Duncan follow-up tests, the results obtained had a significant effect on the hatchability of cork fish eggs.
