摘要
菊黄东方鲀在土池养殖环境下生长速度较快,平均日增长体重达0.658g,成活率达86.7%。每日有早晨和傍晚两个摄食高峰,每次的投喂时间在1～2h,早晨的投喂量占日摄食量的三分之一左右。早期日投饵率为2.0%～3.0%,后期为1.5%～2.0%,根据实际情况进行适当修正。正常情况下换水量在20%～40%。坚持"以防为主,防治结合"的原则,主要从水质管理、饵料管理和药物施用三个方面进行控制、预防和治疗菊黄东方鲀病害。
Fugu flavidus has good nutritional value, it is a multi - purpose species of fish, which is wide - used in different fields. The technology of culture in mud ponds will add culture species and increase its profits in the Fugu culture industry. This paper will provide a technical guide for the culture fieId based on daily management, feeding and water quality management, dis- ease preventing and cure. The result showed that Fugu flavidus grew quickly in mud ponds with weight growth rate of 0. 658g/ day, and the survival rate was 86.7%. There were two feeding peaks at dawn and dusk one day, the time of feeding would be for 1 - 2hours, and the amount of feed at dawn accounts for 1/3 of the total daily amount. The daily feeding rate was 2. 0% ~ 3.0% in early -stage, and 1.5% -2.0% in late - stage, which had to be modified in abnormal condition. The amount of water exchange was 20% ~ 40%. According to the principle of ＂prevention was the first combined with treatment＂, the disease will be control, prevented and treated mainly by the management of water quality, feed and drugs using.
