Embodiment 1

[0043] The experimental mullet provided in this example had an initial body length of 3.08 ± 0.07 cm, and was temporarily raised in a 500 L culture tank 10 d at a temporary density of 1.4 fish / L. The whole experimental process is carried out in the workshop. The seawater is taken from the open sea, and enters the workshop after being coarsely filtered through a sand filter; the fresh water is taken from mountain springs, and is filtered through a mesh bag before entering the workshop to remove larger particles of impurities in the water. A total of 500 juvenile mullets (0.2 / L) were transferred to the nursery workshop 5m 3 (250 × 250cm, depth of water 80cm) in the square breeding pond of 10 days. During the temporary breeding period, feed granular commercial bait twice a day until full.

[0044] At the beginning of the temporary breeding period, the salinity is 15.0±2.0‰, and fresh water is continuously poured into the pond to reduce the salinity of the culture pond every day,...

Embodiment 2

[0051] Refer to Example 1 for temporary rearing of mullet juveniles, osmotic induction and preparation of alizarin red staining solution mother solution provided in this example.

[0052] Dip dyeing container B uses a holding tank with a capacity of 60L, adds filtered aquaculture water, and prepares 30L of dip dyeing marking solution with 300mg / L of mother liquor, adjusts pH to 7.6, and natural water temperature (23±2.3°C). 110 mullet juveniles were randomly placed in each dipping bucket, and the air pump was used to inflate continuously for a dipping time of 12 hours.

Embodiment 3

[0054] Refer to Example 1 for temporary rearing of mullet juveniles, osmotic induction and preparation of alizarin red staining solution mother solution provided in this example.

[0055] Dip dyeing container B uses a holding tank with a capacity of 60L, adds filtered aquaculture water, and prepares 30L of 450mg / L dip dyeing mark liquid with the mother liquor, adjusts the pH to 7.6, and the natural water temperature (23±2.3°C). 110 mullet juveniles were randomly placed in each dipping bucket, and the air pump was used to inflate continuously for a dipping time of 12 hours.

Abstract

The invention provides a mugil cephalus juvenile coloring agent, a coloring method and applications of alizarin red in the mark coloring of mugil cephalus juveniles, and belongs to the technical fieldof the tracking and monitoring of enhancement and releasing. Alizarin red is high in solubility and good in marking effect; the scales and fin spines of the colored mugil cephalus juveniles can obtain good marks, and the total marking rate of full sample fluorescence detection can reach 100%; through 40 d of temporary raising tests, mark retention rate is 100%, and mark retention effects are good; and in addition, through the adopting of mark coloring of the alizarin red on the mugil cephalus juveniles, simple operation can be achieved, high-quality marking effects can be obtained, and the survival rate of the mugil cephalus juveniles during marking can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of tracking and monitoring of breeding and release, in particular to a dyeing agent for juvenile mullet, a dyeing method and the application of alizarin red in dyeing and marking of juvenile mullet. Background technique [0002] The mullet (Mugil cephalus) belongs to the order Mugilidae, the family Mugilidae, and the genus Mugil. It is a common eurythermal and euryalline fish in the southeast coast of my country. It can live in fresh water, brackish water and salt water, and likes to inhabit coastal areas and bays. At the estuary of rivers and rivers, it grows rapidly, has a large body and thick flesh, and has a delicious taste. It is one of the main economic fishes aquaculture in brackish water along the southern coast of my country, and it has also been an important species in fishery production throughout the history. [0003] Breeding and release is one of the more direct and effective methods for the con...
