Problems solved by technology

However, the triangular bream has a strong external stress. During the long-distance transportation, the scales and fin rays of the fish often fall off due to the stress, and the fish body is injured or even dies.

Embodiment 1

[0021] A method for improving the survival rate of triangular bream long-distance transportation, adopting the following steps:

[0022] Preliminary preparation: One week before the triangular bream fry with a length of 2 cm are fished out of the pond, feed them with 3 grams of vitamin C per kilogram of feed, and sprinkle vitamin C into the nursery pond at a rate of 1 gram per cubic water body. . Two days before coming out of the pond, perform a net-drawing exercise every day, so that the fry will gather together in high density for 4 hours to strengthen the fish's physique so that it can withstand high-density operations and transportation. Stop feeding the feed one day before leaving the pond to empty the digestive tract of the fry and avoid intestinal damage and water pollution during transportation.

[0023] Preparation of transport solution: Mix clove oil, penicillin sodium solution and absolute ethanol at a volume ratio of 10:1:1 to form a transport solution.

Embodiment 2

[0027] A method for improving the survival rate of triangular bream long-distance transportation, adopting the following steps:

[0028] Preliminary preparation: One week before the 3 cm long triangular bream fry are fished out of the pond, feed with 3 grams of vitamin C per kilogram of feed, and sprinkle vitamin C in the nursery pond at a rate of 1 gram per cubic water body. . Two days before coming out of the pond, perform a net-drawing exercise every day, so that the fry will gather together in high density for 4 hours to strengthen the fish's physique so that it can withstand high-density operations and transportation. Stop feeding the feed one day before leaving the pond to empty the digestive tract of the fry and avoid intestinal damage and water pollution during transportation.

[0029] Preparation of transport solution: Mix clove oil, penicillin sodium solution and absolute ethanol at a volume ratio of 10:1:1 to form a transport solution.

[0030] Packing operation: ...

Embodiment 3

[0033] A method for improving the survival rate of triangular bream long-distance transportation, adopting the following steps:

[0034] Preliminary preparation: One week before the 4 cm long triangular bream fry are fished out of the pond, feed with 5 grams of vitamin C per kilogram of feed, and sprinkle vitamin C in the nursery pond at a rate of 3 grams per cubic water body. . Two days before coming out of the pond, perform a net-drawing exercise every day, so that the fry will gather together in high density for 4 hours to strengthen the fish's physique so that it can withstand high-density operations and transportation. Stop feeding the feed one day before leaving the pond to empty the digestive tract of the fry and avoid intestinal damage and water pollution during transportation.

[0035] Preparation of transport solution: firstly mix clove oil, penicillin sodium solution and absolute ethanol at a volume ratio of 10:1:1 to form a transport solution.

Abstract

The invention discloses a method for improving survival rate of triangular bream in long-distance transport. Anti-stress effect of vitamin C, sedative effect of low-concentration clove oil and antibacterial effect of penicillin sodium are applied, metabolism and stress reaction of fish fry in transportation process are effectively reduced, and injury and infection of the fish fry in the transportation process can be effectively prevented, so that the survival rate is improved.

Description

technical field [0001] The invention relates to a method for improving the survival rate of triangular bream in long-distance transportation, and belongs to the technical field of aquaculture. Background technique [0002] Triangle bream ( Megalobrama tarminalis ) belongs to the genus Bream of Cypriniformes Cyprinidae. It is a freshwater fish that lives in the middle and lower layers. It has the characteristics of miscellaneous food habits, fast growth, few diseases, and strong adaptability. The triangular bream produced in Qiantang River is the most famous. Triangle bream meat is delicious, high in protein, and contains 8 kinds of amino acids necessary for the human body. Compared with other bream fish, it has better economic benefits. In recent years, with the development of artificial propagation and seed cultivation technology, the cultivation of triangular bream has gradually become large-scale. However, triangular bream has a relatively strong external stress. During...
