Selection Technique of Lobster Parent Shrimp

Parent shrimp refers to the sexually mature male and female shrimp used to reproduce shrimp seedlings, the quality of parent shrimp directly affects the quality of shrimp seedlings, so the selection of parent shrimp is particularly important, here we simply understand the selection technology of parent shrimp. Parent shrimp can be selected in September-October of last year or March-April of the same year, with a body weight of 30-50g, complete appendages, health and disease-free, strong activity, and a female-to-male ratio of 2-3:1.

The difference between male and female lobster in appearance

The main results are as follows: 1. the male is obviously larger than the female.

2. The male dragon foot is thick and has a bright red molluscum on the outside, while the female dragon foot is relatively small and does not have red molluscum, even if it has a light color.

3. The male reproductive foramen opens at the base of the fifth pair of footsteps, while the female reproductive foramen opens at the base of the third pair of foot.

4. The abdomen of female shrimp is dilated, while that of male shrimp is relatively narrow.

Through the above four methods to identify the male and female lobster is very simple, according to the male and female ratio of parent shrimp can have a good start in the breeding of shrimp seedlings.
