Problems solved by technology

The in vivo labeling method is costly, complicated to operate, and the labeling effect is not significant
However, the current in vitro marking method has a low mark retention rate, great damage to the fish body, and some marks still fall off, and the operation is cumbersome.

Embodiment

[0015] Example: refer to figure 1 , Japanese yellow croaker rapid listing marking method, it comprises the following steps:

[0016] ① Dissolution at room temperature: 0.02 to 0.2 parts of δ-aminolevulinic acid, 0.1 to 0.5 parts of ms-222, 10 to 40 parts of NaCl, 10 to 60 parts of CaCl 2 Uniformly dissolved in 1000 parts of water; the preferred aqueous solution of this embodiment contains 0.02g / L of δ-aminolevulinic acid, 0.3g / L of ms-222, 20g / L of NaCl, and 20g / L of CaCl 2 50g / L.

[0017] ② Cooling and soaking: Cool the water treated in step ① to 7°C to 18°C, and then put the fish to be marked into the water for 1 to 5 minutes;

[0018] ③Tagging and calibration: Select the fish to be marked after step ②, apply δ-aminolevulinic acid solution with a concentration of 0.2-2g / L on the surface of the fish to the area to be marked, and then complete the tagging operation. In this embodiment, the preferred concentration is 2 g / L of δ-aminolevulinic acid. A listing tag has a T-sh...

Abstract

The invention discloses a quick label-hanging marking method of Japan Nibea albiflora and a special reagent thereof. A treatment reagent consisting of 0.02 to 0.2 part of delta-aminolevulinic acid, 0.1 to 0.5 part of ms-222, 10 to 40 parts of NaCl (sodium chloride), and 10-60 parts of CaCl2 (calcium chloride) is adopted. Compared with the prior art, the special regent has the advantages that the operation is simple, the cost is low, the anesthesia effect is good, the action concentration is low, the performance of controllable recovery time is stable, and the falling rate of label is low.

Description

technical field [0001] The invention relates to a technique for marking fish, in particular to a rapid listing and marking method for Japanese yellow croaker and a special reagent thereof. Background technique [0002] Japanese croaker Nibea japonic It belongs to the order Perciformes, belongs to the genus Crowfish, and is a large-scale high-quality edible fish, mainly distributed in the East China Sea, South China Sea and the southern coast of Japan. However, due to the decline of global marine resources due to overfishing, environmental pollution, habitat destruction, etc., and the reduction of fishing grounds, the current natural distribution is very limited, and there are only a small number of catches in the East my country Sea. Therefore, how to protect the East China Sea The precious resources of black catfish in the northern waters of Zhejiang Province are imminent. With breakthroughs in the domestication and seed breeding of Japanese yellow croakers, East China Sea...
