Method for controlling temporary breeding and packing prepared for aquatic product transportation

Abstract

The invention discloses a method for controlling temporary breeding and packing prepared for aquatic product transportation. According to the method, when fishes are put into a temporary breeding tank, the water temperature of the temporary breeding tank is controlled to be between 8 and 25 DEG C, and the temporary breeding time of the fishes in the temporary breeding tank is 20 to 30 hours; during temporary breeding, after the fishes are put into the temporary breeding tank for 4 hours, the water temperature is reduced for 0.15 to 0.3 DEG C each hour, and when the water temperature is reduced for 2 to 2.5 DEG C, the water temperature is kept unchanged; in the temporary breeding tank, the water is replaced continuously in a circular mode, the salinity of the water in the temporary breeding tank is 0.1 to 0.5 percent, the PH value of the water quality is 5 to 8, the ammonia nitrogen content in the water is less than 0.6 milligram / liter, and the nitrite content in the water is less than 0.2 milligram / liter; and during packing, the water temperature in a packing box is controlled to be between 4 and 19.5 DEG C, the salinity of the water in the packing box is 0.1 to 0.5 percent, the PH value of the water quality is 5 to 8, the ammonia nitrogen content in the water is less than 0.6 milligram / liter, the nitrite content in the water is less than 0.2 milligram / liter, and the dissolved oxygen in the water is more than 3 milligram / liter. Compared with the prior art, by the method, the transportation survival rate can be improved, and the viability of aquatic products is improved, so that the freshness and deliciousness of meat is kept.

Description

technical field [0001] The invention relates to the field of fresh-keeping and transportation of fresh aquatic products, specifically a method for temporary breeding and packing control prepared for the transportation of aquatic products. Background technique [0002] Fresh aquatic products are complete in color, aroma and taste, and have high nutritional value. However, after the fish is dead, the fish body is corrupted, the taste and nutritional value are reduced, and the safety is reduced. During transportation, many fish die due to lack of oxygen or adaptation to the environment. The freshness, preservation and long-distance transportation of aquatic products have always been a difficult problem, which is one of the main factors restricting the development of the aquatic industry. With China's entry into the WTO, this problem has become increasingly important. [0003] Since the reform and opening up, my country's aquatic industry has developed rapidly. In 1980, the to...
