水產研究(1993年創刊)-光合菌及枯草桿菌對點帶石斑吋苗蓄養之應用
主題: 光合菌及枯草桿菌對點帶石斑吋苗蓄養之應用
摘要(中):
石斑魚養殖過程中,因魚隻代謝產物及殘餌使水體逐漸累積大量氨態氮、亞硝酸及有機物而影響蓄養環境之水質,導致魚隻產生疾病,因此水質環境的改善及減少病原菌感染機會是提高養成的重要關鍵。本研究主要探討光合菌 (Rhodovulum sulfidophilum) 及枯草桿菌 (Bacillus subtilis) 對數種病原菌之抑制能力,以及分別添加於點帶石斑 (Epinephelus coioides) 養殖環境中,對池水水質改善及石斑魚吋苗成長之影響。In vitro試驗結果顯示,光合菌及枯草桿菌濃度為 104 CFU/ml 時,對病原菌 Vibrio alginolyticus、V. anguillarum、V. parahaemolyticus 有抑制能力。定期添加104 CFU/ml光合菌及枯草桿菌於石斑魚養殖池水中,試驗組氨態氮及亞硝酸濃度皆較對照組低,且較為穩定。本試驗所獲得之結果可應用於點帶石斑吋苗蓄養,可以達到抑制病原菌,減少疾病發生,同時還能降低水中氨態氮及亞硝酸濃度,穩定水質,以提供良好的養殖環境,達到提高點帶石斑育成率及收益之目的。

摘要abstract(英): Due to the discharge of metabolic waste in feces and the accumulation of uneaten feed, cultural ponds are easily polluted by massive ammonia nitrogen, nitrite, and organic matter. It deteriorates the cultivation environment and usually causes prevalence of diseases in fish. Therefore, the improvement of the cultivation environment and the reduction of infection opportunity for pathogens are the key factors for enhancing survival rate. The aim of this research is to investigate the effects of the probiotic, photosynthetic bacteria Rhodovulum sulfidophilum and Bacillus subtilis on the inhibition of several Vibrio pathogens in orange-spotted grouper, Epinephelus coioides aquaculture. In vitro, the R. sulfidophilum and B. subtilis at the concentration of 104 CFU/ml effectively inhibited the multiplication of Vibrio alginolyticus, V. anguillarum, and V. parahaemolyticus in plates. The addition of R. sulfidophilum and B. subtili into water can mitigate the amounts of ammonia nitrogen and nitrite in the ponds and thus stabilize water quality. The research showed that adding R. sulfidophilum and B. subtilis to the grouper culture pound can stabilize water and inhibit pathogens; create a good nursery environment for grouper culture ; reduce the prevalence of disease; and elevate the breeding gains.
