Anesthesia of brown grouper by combination of electricity and carbon dioxide

Abstract

The invention discloses a transportation method for keeping alive brown grouper anesthetized by combined electricity and carbon dioxide, and belongs to the field of aquatic product transportation. The method includes: after the brown grouper is stopped feeding and temporarily raised in seawater with a dissolved oxygen concentration of 8.0-12.0mg / L at 22.0-28.0°C, it is anesthetized by a combination of electricity and carbon dioxide and then placed in a seawater containing spray water. Distributed thermal insulation container, under the condition of continuous or intermittent atomized spraying, thermal insulation transportation. The present invention combines electric anesthesia and carbon dioxide anesthesia to quickly anesthetize the brown grouper, and at the same time ensures the survival of the brown grouper in an environment with sufficient oxygen and little water by atomizing and spraying seawater. Under conditions of stable anesthesia to keep alive, the survival rate is high and safe and effective, which can meet the needs of e-commerce platforms for fresh transportation.

Description

technical field [0001] The invention belongs to the field of aquatic product transportation, and in particular relates to a transportation method for keeping alive brown grouper anesthetized in combination with electricity and carbon dioxide. Background technique [0002] Brown-spotted grouper, also known as tiger grouper, is a species of seawater fish with high economic value. It is mainly distributed in tropical and subtropical seas. The suitable temperature range is 15.0-34.0°C, the most suitable water temperature is 22.0-28.0°C, and the suitable salinity range It is wider and can survive in sea areas with a salinity above 10‰. Brown-spotted grouper is a carnivorous fierce fish that preys on benthic crustaceans, various small fishes and cephalopods in a surprise manner. It is rich in nutrients and has high nutritional and economic value. [0003] With the improvement of urban consumption level and the rapid development of e-commerce, the demand for fresh and live brown g...

Problems solved by technology

The disadvantage of drug anesthesia is that drug residues are likely to exist, which does not meet the needs of green food consumption; low-temperature seawater preservation needs to carry a large amount of seawater, which has the disadvantages of long cooling time, high energy consumption, and high cost; although carbon dioxide anesthesia preservation can quickly anesthetize Brown-spotted grouper, but due to individual differences in the anesthesia state of brown-spotted grouper, it is easy to wake up from anesthesia, especially in the process of anhydrous transportation, and its survival rate is greatly reduced
