Method for labeling shrimps and shrimp label

Abstract

The invention discloses a method for labeling shrimps, particularly for fixing a shrimp eyestalk label to a shrimp body through a shrimp eyestalk. The label comprises a label string anchored and sleeved on the shrimp eyestalk, and a label body loaded with a mark, wherein the label string connected to the label body constitutes a stretchable closed ring on one side of the label body; and a central hole penetrating the label body is formed on the label body, so that the label string can be in non-fixed connection with the label body via the central hole to achieve the stretchability. When in use, the eyestalk on one side of the shrimp is lifted up, so that the ring-shaped part of the label string can be sleeved at the middle part of the eyestalk; and the label string is properly pulled, and the two free ends of the label string are clamped and burned by a hot tip-shaped body, so that the tail end of the label string can be sealed up and aligned with the label body. The shrimp label has the advantages of small size, light weight and no toxicity or side effects, thereby causing no impact on the ingestion and movement of the shrimps; the shrimp label is corrosion-resistant, high-pressure resistant and non-fading, so the shrimp label is particularly compatible to the life habit of aquatic organisms; and by using the shrimp eyestalk as the loading part for the label, the label is no longer physiologically effected by shrimp molting and in-vivo metabolism, so the shrimp label is durable and reliable.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for marking shrimp and a label used therefor. Background technique [0002] There are many kinds of shrimps with rich nutritional value. Marine shrimps include various prawns, new prawns, imitation prawns, lobsters, mantis shrimp, etc.; It is rich in protein, and also rich in minerals and trace elements (such as calcium, phosphorus, iron, zinc, iodine, etc.), with high nutritional value and extremely beneficial to human health. my country is a big aquaculture country in the world, and the output of aquatic products has ranked first in the world for many years. Among them, the output of only cultured prawns has exceeded 1 million tons. In recent years, the demand for high-quality prawn seed has grown rapidly. Therefore, the development of new species breeding of shrimp has become one of the frontier topics in the current aquaculture industry. The species of prawns ...

Problems solved by technology

There are obvious deficiencies in both types of marking: the laser marking equipment on the body surface is very expensive, and it can only be kept for a short period of time. Once the prawn molts, it will fall off with the shell

Because shrimps often molt during their growth, visible marks attached to the body surface are not easy to achieve. At present, laser marking on the body surface is only seen in a few foreign companies for the company's export broodstock.

Fluorescent digital labels or fluorescent powder need to be injected into the muscle tissue under the dermis of the prawns, which not only requires skilled operators, but also causes physical damage to the prawns, and even leads to the death of the prawns from infection

Special ultraviolet light equipment is required to distinguish marks. Shrimp is an aquatic animal. Due to changes in the water environment, the body color of the prawns changes, or the immune response of the prawns, the marks implanted under the skin are often difficult to identify; the fluorescent powder injected into the skin is often difficult to identify. Actively cleared by prawns, or the fluorescence is quenched with the growth of culture time, making it difficult to distinguish and identify the markers
