活鱼运输包括鱼苗、鱼种、亲鱼和成鱼的运输。搞好活鱼的安全运输工作,关系到养鱼专业户的经济效益,可以沟通“产、供、销”的渠道,对于促进水产事业的发展和改善人民生活有明显的作用。 (一) 活鱼安全运输需要注意的几个问题: (1) 活鱼在运输途中所消耗的溶氧,要疫法及时给以补充。 (2) 各种鱼类运输,水温要保持在一定范围之内。换水加水的温差不宜过大,一般不超过4℃。夏秋季运输需要隔热降温。 (3) 水质要求清洁无毒,含氧量高。运输途中发现水质变坏或鱼浮头时,就应加换新水。鱼类排泄物
Live fish transport includes fry, fingerlings, broodstock and adult fish. Improving the safe transportation of live fish is of great importance to promoting the development of aquatic products and improving the people’s livelihood because it relates to the economic benefits of specialized fish-farming households and enables them to communicate “production, supply and marketing.” (A) several issues need to pay attention to the safe transport of live fish: (1) dissolved oxygen consumed by live fish in transit, to the epidemic in time to be added. (2) all kinds of fish transport, water temperature to be maintained within a certain range. Water temperature difference should not be too large, generally not more than 4 ℃. Summer and autumn transport need to heat and cool. (3) water quality requirements clean non-toxic, high oxygen content. When found in the water quality deterioration or fish floating head, it should be replaced by new water. Fish excrement
