Embodiment 1
[0037] (1) 25g sodium lauryl sulfate, 120g urea, 5g potassium sorbate, 3g citric acid and 5g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 200g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;
[0038] (2) Color retention fixation: put the fish into a benzocaine solution with a concentration of 0.4 g / L, and euthanize to death; take out the fish body and place it in the color retention fixative prepared in step (1) for fixation 2 Days later, replace with fresh color retention fixative and continue to fix for 7 days;
[0039] (3) Anatomy and trimming: take out the fish, saw the fish body fixed in step (2) along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and remove one side gill cover and body wall. The visceral structures such as gills, body cavity thyroid, heart, ...
Embodiment 2
[0044] (1) 25g sodium lauryl sulfate, 105g urea, 5g potassium sorbate, 3g citric acid and 20g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 200g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;
[0045](2) Color retention fixation: put the fish into a benzocaine solution with a concentration of 0.2 g / L, and euthanize to death; take out the fish body and place it in the color retention fixative prepared in step (1) for fixation 1 Days later, replace with fresh color-retaining fixative and continue to fix for 7 days;
[0046] (3) Anatomy and trimming: The fish was taken out, the fish body fixed in step (2) was sawed along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and one side gill cover and body wall were removed. The visceral structures such as gills, body cavity...
Embodiment 3
[0051] (1) 15g sodium lauryl sulfate, 150g urea, 2g potassium sorbate, 5g citric acid and 4g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 150g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;
[0052] (2) Color retention fixation: the fish was placed in a benzocaine solution with a concentration of 0.2 g / L, and anesthetized to death; the fish body was taken out and placed in the color retention fixative prepared in step (1) for fixation 3 Days later, replace with fresh color retention fixative and continue to fix for 3 days;
[0053] (3) Anatomy and trimming: The fish was taken out, the fish body fixed in step (2) was sawed along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and one side gill cover and body wall were removed. The visceral structures such as gills, ...
