Problems solved by technology

Although these two methods provide a good method for the transportation of live fish and have achieved good results, the operation is more complicated and costly and labor-intensive. The biggest similarity is that both require water as a carrier, and a large amount of water is transported. The process will bring a lot of inconvenience. During the transportation process, due to the high density of fish in the water, the violent movement of the fish in the water environment will also cause the fish to be injured.

example 1

[0022] Example 1: Select a number of healthy and lively crucian carp from the Chaimi River Basin in Huai'an City, with a body length of 11-13 cm. First of all, the healthy and active crucian carp caught is placed in clean water for more than 24 hours to keep the water circulation and cleanliness; then, the live fish is transferred to the diluent of white wine for 20 minutes to induce dormancy. The volume multiple of the liquor dilution is 25; finally, the live fish that have entered a dormant state are taken out of the liquor dilution, and placed in an anhydrous humid environment or in a special container for long-distance transport, and the anhydrous environment temperature is 6°C. The average survival time of this batch of fish was 21 hours.

[0023] Example 2: Select a number of healthy and lively crucian carp from the Chaimi River Basin in Huai'an City, with a body length of 11-13 cm. First of all, the healthy and active crucian carp caught is placed in clear water for more than 24 hours to keep the water circulation and cleanliness; then, the live fish is transferred to the diluent of white wine for 30 minutes to induce dormancy. The volume multiple of liquor dilution is 15; finally, the live fish that have entered a dormant state are taken out of the liquor dilution, and placed in an anhydrous humid environment or in a special container for long-distance transport, and the anhydrous environment temperature is 1 °C. The average survival time of this batch of fish was 18 hours.

example 3

[0024] Example 3: Select a number of healthy and lively crucian carp from the Chaimi River Basin in Huai'an City, with a body length of 11-13 cm. First, catch healthy and active crucian carp and put them in clean water for more than 24 hours to keep the water circulation and cleanliness; then, transfer the live fish to the diluent of white wine for 40 minutes to induce dormancy. The volume multiple of the liquor dilution is 100; finally, the live fish that have entered a dormant state are taken out of the liquor dilution, and placed in an anhydrous humid environment or in a special container for long-distance transport, and the anhydrous environment temperature is 12°C. The average survival time of this batch of fish was 15 hours.

Abstract

The invention discloses a method feeding fishes without water, which is mainly composed of following procedures: firstly, placing a healthy and active crucian fished or brought from market into clean water over 24h for temporary feeding and maintaining the circulation and cleanness of the water; then transmitting the living fish into alcohol diluent for 10min to 40min for abduction and dormancy; wherein, the alcohol diluent refers to the diluent that injecting alcohol into water and the volume achieves 5 to 1000; finally, fetching out the living fish in dormancy status from the alcohol diluent and then placing into a moist environment without water or special container for long distance transportation; wherein, the temperature of the moist environment without water ranges from 0 DEG C. to 14 DEG C. The invention fulfills the live keeping transportation without water by making the fish in dormancy status, which features simple method, low transporting cost and no side effects.

Description

technical field [0001] The invention relates to a fresh-keeping and transportation method for live fish, in particular to a method for keeping fresh-water fish alive without water. Background technique [0002] my country's aquaculture has a long history, as far back as 3000 years ago, there was a record of fish farming. In addition to its ornamental value, fish meat is delicious, unique in flavor, low in fat and high in protein. It is an indispensable and important part of a reasonable dietary structure and has become an important source of animal protein intake for people. With the development of the economy and the improvement of people's living standards, people's demand for fish is increasing today, especially people's requirements for the quality and nutritional value of fish are getting higher and higher. more and more important. However, there is often a distance between the place of origin and the place of consumption of aquatic products, and the transportation of...
