How to raise lobster in Boston

Boston lobster is high in protein, low in fat, rich in vitamins and trace elements, tastes delicious, and nutrients are easily absorbed, so it is sought after by many families and banquets. At present, more and more people are raising, so how to raise Boston lobster?

1. Temperature: Boston lobsters are naturally distributed in subtropics and tropics. A better growth rate can be obtained between 18 ℃ and 32 ℃.

two。 Water quality: water source, mainly using surface water of unpolluted rivers, lakes, reservoirs and other large water bodies as water source. The pH value of water, in the process of culture, had a lowest value of 6.10 and a maximum value of 9.33, but 6.5 Mel 9.0 was better, preferably neutral and partial alkali. Dissolved oxygen in water, Australian lobster can survive for a short time although it is resistant to hypoxia and dissolved oxygen less than 1 mg / L, but if it is in a state of low dissolved oxygen for a long time, it will affect its growth and survival rate. Adopting micro-running water or adding new water regularly can promote the growth of lobster.

3. Pond: the pond should be rectangular, the area is unlimited, but it is better to take 2mur5 mu, the water depth is 0.9mur1.5 meters, the pond long axis direction should be the same as the summer wind direction. The bottom of the pool is hard soil, there is no silt, the pool wall must have a slope, and the slope must be greater than 3 ∶ 1. The pond should have a good drainage and irrigation system, with water entering the upper part of the pond at one end and drainage at the bottom of the pool at the other end. The bottom of the pond should have a submerged plant area with an area of about 1pm and 5 bottoms, and there should be sufficient artificial concealment, such as waste tires, nets, PVC pipes, waste tile tanks, bamboo rafts, etc. Conditional ponds can be equipped with aerators.

4. Feeding: micro-flow aquaculture or adding 2 Mel fresh water 3 times a week. Fixed-point, timing, qualitative and quantitative feeding should be adopted, and the types of feeding should be diversified as far as possible. During the high temperature period in summer, we should pay attention to increasing the amount of water flow or water injection, and the number of water injection, and the aerator can be turned on at night.

Boston lobster grows slowly, takes a long time to breed, and the cost of breeding is relatively high, so we must pay attention to it before breeding. If it is family farming, you can add a little salt and a few drops of cooking oil to the water, which can be preserved for two to three days.
