, lobster habits. Lobster belongs to insect shell animals, similar to crabs, with a pair of specially developed chelates and the habit of digging caves. Generally, lobsters dig caves near the water's edge. Lobsters like shade and fear light. When the light is weak or dark, they climb out of the cave. When the light is strong, they sink to the bottom or hide in the cave. Lobsters have spawning periods twice a year in spring and autumn. A pair of male and female lobsters can breed up to 480 shrimp seedlings at a time. Usually, the lobsters listed in early spring are the shrimp larvae bred in the autumn of last year, while the shrimp larvae bred in spring only need to be bred for more than 60 days to be listed. Lobster farmers only need to keep the large whole lobster for planting in the first year. In autumn, the lobster will go into the cave to give birth. In the second year, they do not need to buy too many lobster seedlings. 2. Big appetite and miscellaneous eating habits.

Lobster is not afraid of dirty and smelly water, but it is very sensitive to chemicals such as pesticides, fertilizers and liquefied petroleum gas. As long as there are these chemicals in the pond, the lobster will be destroyed. Second, lobster breeding technology 1, to create a good lobster growth environment. Lobsters like to make holes. Generally, the depth of caves is 50-80cm, and the depth of some caves is more than 1m. In order to avoid escaping from the holes, the width of the ridges around the aquaculture water body should be more than 1.5 m, and 0.5 m high anti-escape nets or smooth anti-escape walls and anti-escape boards should be set up around the ridges. The anti-escape boards and fences should also be buried 2m deep to prevent lobsters from escaping. At the same time, the river pond simulates the ecological environment of lobster under natural conditions.Its length × width cannot be greater than 330 × 200 (mm × mm), and its thickness is generally 1.6 mm.This chapter is the last lecture on design patterns.
