Problems solved by technology

[0003] How to mark and release juvenile flat scorpionfish has always been a problem that plagues their proliferation and release. In the past, methods such as fin clipping, listing, cold branding, and tracer atom marks were used to mark, but each had its own defects and damages: fin clipping The method is easy to cause fish to be infected with diseases and affect the swimming of the fish, and the part of the fins that are cut off in the subsequent growth process can be regen

Embodiment 1

[0017] In September 2009, in the seed cultivation workshop of Yantai Baijia Aquatic Products Co., Ltd., located in Huangshanguan Town, Longkou City, Yantai, 450 juvenile fishes of Scorpius xushi were selected, and the juvenile fish of scorpion scorpion Xu (full length ≥ 100mm) were selected. , individual ≤ 100mm) mark, stop eating for one day before marking.

[0018] Inhale 1mL liquid fluorescent dye into the fluorescent marker implanter for later use.

[0019] Use a 200L PVC tank to hold 100L of seawater at a temperature of 19.5°C, add 30mL of 2-phenoxyethanol (total concentration of 300μL / L in seawater), and fish the juvenile Scorpene chrysalis into it for stress suppression, usually within 3 minutes The juveniles lay on their sides at the bottom of the tank and did not respond to struggling when touched by hands. At this time, they began to be marked with fluorescent pigments.

[0020] Use the fluorescent marker implanter to inject the fluorescent liquid into the epidermis...

Abstract

The invention relates to a method for release marking on juvenile fish of Sebastes schlegeli, which comprises: firstly, selecting juvenile fish, with a total length of more than or equal to 100 millimeters, of Sebastes schlegeli, and stopping feeding the juvenile fish one day earlier to evacuating the alimentary tracts of the juvenile fish; and secondly, bathing the juvenile fish of Sebastes schlegeli in seawater solution of a stress inhibitor, namely seawater solution of 2-phenoxy ethanol at a concentration of 300 muL/L, in a 10 to 200 liter plastic or glass fiber reinforced plastic water tank for 3 minutes, burying fluorescent liquid in the under jaw parts of the juvenile fish, namely, leaving an about 8 to 10 millimeters long fluorescent mark line on the under jaws of the juvenile fish, by using a fluorescent mark burier with a capacity of 0.3 milliliter when the juvenile fish stops struggling during manual operation and culturing the marked juvenile fish in a culture pond for 8 to 10 days before propagation release. Obviously, the method of the invention is simple, convenient in operation, high in stability, easy to recognize and suitable to be used in large-scale propagation release.

Description

technical field [0001] The invention relates to a method for marking organisms, in particular to a method for releasing and marking the juveniles of the flat scorpionfish. Background technique [0002] Sebastes schlegeli Hilgendorf (Sebastes schlegeli Hilgendorf), commonly known as blackhead and black fish, is an offshore reef-loving demersal fish, distributed in the western North Pacific Ocean, in my country's Bohai Sea, Yellow Sea and East China Sea, especially in the Yellow Sea and Bohai Sea. Xu's flat scorpionfish is large in size, delicate in meat quality, high in taste, wide in seed sources, strong in disease resistance, low temperature resistant, and fast in growth. The overfishing of nearshore fisheries in the past 20 years has led to a sharp decline in the natural resources of the scorpionfish, and the catch has decreased year by year. In order to protect natural resources, restore and improve the wild population of the scorpionfish, fisheries in northern my country...
