The potential for the development of Snakehead farming (Channa striata Bloch, 1793) is still very large, not only by using simple technology (conventional) but also using the biofloc method. This study aims to determine the effect of water quality parameters on the growth of snakehead fry that is reared using biofloc and conventional methods. This research was conducted by comparing snakehead fry rearing using the biofloc method and conventional method with details of treatment 1 (P1) using the biofloc method with as many as 6 replicates and treatment 2 (P2) using the conventional method as many as 6 replicates. DO variable does not affect length gain in biofloc and conventional treatments (p>0.05). The pH variable did not affect weight gain in biofloc and conventional treatments (p>0.05). The variables of pH, DO, Temperature, and ammonia together affect the length gain in bioflok and conventional treatments (p0.05). Based on the mean comparison test (independent t-test), the mean water quality in terms of pH and DO in the biofloc and conventional treatments were different, with the mean pH in the conventional treatment higher than in the biofloc treatment, while the mean DO in the biofloc treatment was higher than the conventional treatment. Based on the mean comparison test (independent t-test), the mean temperature, ammonia, length, and weight growth of snakehead fry in biofloc and conventional treatments are the same. |
