1, the back of the armor: the back of the armor of the wild snapper is thin and uniform, and with a waxy sense of light, while the back of the armor of the farmed snapper is a little thicker, without a sense of light. 2, the body: because the wild snapper is active in the wild for many years, so the body is proudly healthy and muscular, and the farmed snapper's activity is relatively small, so the body Yong swollen and muscular flaccidity. 3, the belly of the armor: wild snapper's skirt is thicker, and is not easy to hang down, while the skirt is softer and usually easy to fall down. The skirt of wild snapper is thicker and usually does not hang down easily, while the skirt of farmed snapper is softer and usually hangs down easily.

First, how to distinguish between wild and farmed snapper

1, the back of the armor

(1) wild snapper: the back of the armor is thin, even and clean and flat, with a waxy feel, and you can vaguely see the armor corridor.

(2) Farmed snapper: the back of the armor is slightly thick and rough, no light texture, it is difficult to see the armor corridor.

2. Body shape

(1) Wild snappers: Because wild snappers live in the wild for a long time, they need to look for food on their own, so they have a proud and healthy body and tight muscles.

(2) farmed snappers: farmed snappers, because of the long-term life in the feeding pool, will eat food every day, do not have to find their own, so it is the body Yong swollen, muscle flaccid.

3. Skirt

(1) wild snapper: the skirt is thicker, not easy to hang down, more gelatinous.

(2) farmed snapper: the skirt is softer, not fleshy, easy to hang down.

4, abdominal armor

(1) wild snapper: abdominal cartilage elasticity is relatively large, with a finger against the pressure can feel the rebound force.

(2) farmed snapper: abdominal cartilage elasticity is relatively weak, with a finger against the pressure felt more soft collapse, rebound force is not as good as the wild snapper.

Second, the snapper farming a few years will lay eggs

1, snapper farming generally 2-3 years or so can lay eggs, but snapper's physical conditions, living environment and other factors are different, so the time of the egg is also different, for example, some precocious snappers, farming more than 1 year when the egg can be laid, and a part of snappers need three years or so to lay eggs, so snappers can lay eggs, so the time of the egg also varies. For example, some precocious snappers can lay eggs after 1 year of breeding, while some snappers need 3 years to lay eggs.

2, snappers generally in the annual June-September egg-laying, egg-laying period is more concentrated in the summer, and many times spawning, generally 1 can lay about 20-30 eggs, egg-laying time is more concentrated in the second half of the night, i.e., 0-6 o'clock, which is related to the snappers' habit of being quiet and afraid of noise.

3, in the egg female snapper will first climb out of the water, and then in the terrain is relatively high, windward and sunny, no stagnant water under the bushes to spawn, especially in the soft and moist sand and powdered soil digging holes to spawn, spawning is completed, the snapper will use the back claws to pick up the sand and soil as a way to cover the spawning holes, and then with the abdomen to the sand and soil to grind the compaction, generally does not leave obvious traces.
