Ecological ice-temperature water-free alive-keeping method for lateolabrax maculatus

Abstract

The invention discloses an ecological ice-temperature water-free alive-keeping method for lateolabrax maculatus. The ecological ice-temperature water-free alive-keeping method is characterized in thatthe respiratory metabolism rate of the lateolabrax maculatus can be properly reduced through short-term fasting temporary culture, then the water temperature is reduced to the dormant temperature ofthe lateolabrax maculatus at proper temperature fall rate, the lateolabrax maculatus is adapted to a dormant water environment for a period of time, finally oxygen, carbon dioxide and nitrogen are filled for packaging, and the lateolabrax maculatus is kept alive without water at low temperature; and the lateolabrax maculatus can survive 8 hours in a water-free state, the lateolabrax maculatus is placed in a water environment with the temperature of 4 DEG C after being kept alive without water, and the survival rate of the lateolabrax maculatus can reach 100% within 1 day after the environmenttemperature returns to normal at the temperature rise rate of 5 DEG C / h. According to the ecological ice-temperature water-free alive-keeping method for the lateolabrax maculatus, wet sawdust packaging is replaced with alive keeping liquid packaging, so that the size of a container is reduced, the transportation weight is reduced, abd the transportation cost is effectively reduced; and the methodis particularly suitable for express delivery and air transportation, and the water-free alive transportation effect of marine fishes is improved, so that higher economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of keeping alive aquatic products, in particular to a method for keeping seawater fish alive without water, especially a method for keeping alive sea bass without water. Background technique [0002] Lateolabrax maculatus belongs to Pisces, Perciformes, Serranidae, Oligorinae, and Lateolabrax. Long, the scales are very rough, the lower jaw is longer than the upper jaw, and the fish mouth is sharper. Perch is a euryhaline fish that likes to inhabit brackish water in estuaries, but can also live in fresh water. It is produced in the fresh water bodies along the coast of my country and the sea, and there are more in the East China Sea and the Bohai Sea. The main producing areas are Qingdao, Shidao, Qinhuangdao and Zhoushan Islands. The fishing season is spring and autumn, and October to November is the peak fishing season. Sea bass has delicious meat and higher nutritional value than freshwater sea bass. It is one of...

Problems solved by technology

[0003] Due to the large geographical span of production and sales, the imprecise preservation technology and the imperfect configuration of transportation equipment, etc., the transportation cost of seawater fish is high, and the loss rate of long-distance transportation is high (over 10%), which greatly restricts the development of the seawater fish sales market.
