Catfish farmers manage several bacterial diseases on their farm operations. Among them, enteric septicemia of catfish (ESC) is the most widespread and economically significant disease. Farmers have limited ESC management choices, primarily through feed restriction or treatment with medicated feed (Aquaflor [florfenicol] or Romet [ormetoprim sulfadimethoxine]). However, the management of ESC on catfish farms has economic implications given the production losses associated with the feed restriction approach and the expense of medicated feeds. This relative economic study evaluated the economics of ESC management on commercial catfish operations using medicated feeds as opposed to the feed restriction approach. The relative economic benefit of disease management varied depending on the nature of the catfish production phase, degree of disease progression, and intensity of culture practices. This study provides economic justification for the use of medicated feeds as opposed to restricted feeding in the fingerling production phase, with net benefits ranging from US$1,600/acre to $1,800/acre. However, its use in food fish production should involve consideration of various factors, such as the market price of the fish and the foregone revenue along with production aspects, such as the size of the fish and the intensity of culture practices. The study underscores the economic importance of medicated feeds in the judicious management of bacterial diseases in catfish farming.

Cat鱼养殖的药物饲料干预：经济角度

farmers鱼养殖者在其养殖场经营着几种细菌性疾病。其中，of鱼的肠道败血症是最普遍和经济上重要的疾病。农民的ESC管理选择有限，主要是通过限制饲料或用含药饲料（Aquaflor [florfenicol]或Romet [ormetoprim sulfadimethoxine]）进行处理。然而，鉴于restriction鱼饲料限制方法的生产损失和加药饲料的费用，cat鱼养殖场的ESC管理具有经济意义。这项相对经济的研究评估了使用含药饲料而不是限制饲料的方法，对商业cat鱼进行ESC管理的经济性。疾病管理的相对经济利益因the鱼生产阶段的性质而异，疾病进展程度和养殖习惯强度。这项研究为使用药饲料提供了经济上的合理性，与鱼种生产阶段的限制饲料相反，其净收益从1600美元/英亩到1800美元/英亩不等。但是，将其用于食用鱼生产时应考虑各种因素，例如鱼的市场价格和已放弃的收入，以及生产方面的因素，例如鱼的大小和养殖方式的强度。该研究强调了含药饲料在明智地管理cat鱼养殖细菌性疾病方面的经济重要性。净收益从1600美元/英亩到1800美元/英亩不等。但是，将其用于食用鱼生产时应考虑各种因素，例如鱼的市场价格和已放弃的收入，以及生产方面的因素，例如鱼的大小和养殖方式的强度。该研究强调了含药饲料在明智地管理cat鱼养殖细菌性疾病方面的经济重要性。净收益从1600美元/英亩到1800美元/英亩不等。但是，将其用于食用鱼生产时应考虑各种因素，例如鱼的市场价格和已放弃的收入，以及生产方面的因素，例如鱼的大小和养殖方式的强度。该研究强调了含药饲料在明智地管理cat鱼养殖细菌性疾病方面的经济重要性。
