In natural environment, it usually takes 6- 12 months for a lobster to grow into a big lobster, at which time its weight is about 30- 100g, and it can grow up in about 6 months under artificial feeding conditions. Lobsters grow up every time they molt 1 time, so it is very important to supplement calcium to lobsters. In the process of raising lobsters, be sure to have enough food. If there is not enough food, lobsters will kill each other.

1. How long does it take for lobsters to grow into big lobsters?

1. In natural environment, it takes 6- 12 months for lobsters to grow into big lobsters. At this time, the weight of lobsters is generally around 30- 100 g. In the case of artificial feeding, lobsters can grow up in about 6 months, because the artificially fed food is rich enough to meet their growth needs, so they grow faster.

2. Lobster has strong viability. It can climb ashore for gill breathing and survive in an anoxic environment. The pH value of the water suitable for lobster growth is about 5.8-9. When the dissolved oxygen is lower than 1.5mg/L and the normal dissolved oxygen is above 3 ml/L, lobster can survive normally.

If you want lobster to grow fast, you must pay attention. Lobsters grow up every time they molt 1 time. Lobsters need to absorb a lot of calcium when molting, so calcium should be supplemented when raising lobsters. When lobsters molt and grow new shells, a lot of calcium is needed at this stage. At this time, they must be added with foods with high calcium content, so that lobsters will grow faster.

4. Lobsters have the characteristics of 1: they are aggressive and like to grab food. Therefore, it is necessary to ensure adequate food in the process of raising lobsters. If there is not enough food, lobsters will kill each other and cause great losses. Lobsters have a wide range of food habits. Generally, it can eat anything that can bite people, and it can be mixed with animal and plant feed when feeding.

Second, what is the difference between crayfish and crayfish?

1 appearance

(1) There are obvious spikes and protrusions on the shell of crayfish, with thick appendages and big heads. 1 A pair of claws are slender and have obvious spikes.

(2) The appearance of the mole is very smooth, and there are no obvious protrusions and nails. In addition, its attached feet are slender and its tail is relatively large. 1 A pair of claws are smooth and full.

2. Edible taste

(1) Crayfish has a very strong earthy smell, but this smell will be covered up after cooking.

(2) The mole is delicious and slightly sweet.

3. Growing environment

(1) Crayfish does not have high requirements on the environment of its habitat waters. It can survive normally in lightly polluted fields and ditches, and its vitality is relatively tenacious.

(2) Gryllotalps have strict requirements on the growth environment, and any pollution may lead to their death, especially chemical fertilizer and pesticide pollution.
