, 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.

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.So you said that the protective equipment did not play a protective role, Of course it did, In those days, Bulletproof vests and other things are still not popular, Helmets are the most important protective gear, I am lucky to wear a helmet, Otherwise, I would have been a martyr long ago, and I chose whether to wear a helmet or a cloth hat.
