Do you want to feed lobsters in rainy days?

When the dissolved oxygen content in the water is very low, the water quality deteriorates, or in bad weather such as thunderstorm, sultry and even cloudy days, it is necessary to reduce or stop feeding. Lobster requires fresh water, transparency of 30 ~ 40cm, pH value of 7 ~ 9 and dissolved oxygen of more than 4mg/L. ..

When the weather is too cold or too hot, in order to prevent extreme temperature, the pool water can be deepened appropriately to stabilize the water temperature at the bottom of the pool. In the high temperature season from June to August, change the water 1 time every 5-7 days, and the water change amount is 20%-30% of the pool water each time. If it is not convenient to change water, you can replenish fresh water regularly.

Shrimp fry stocking:

Before stocking, the pond should be cleaned and disinfected with quicklime100 ~150kg/667m2 to kill harmful fish and aquatic insects in the pond and avoid enemy invasion. After disinfection for 3 days, water was fed, and after 10, 300 ~ 500 kg/667 ㎡ decomposed organic fertilizer was used to fertilize water, so as to cultivate rich plankton and provide sufficient bait for shrimp seedlings. ?

Generally, shrimps with a body length of 3 ~ 5cm, strong physique and no disease are selected for release, and the stocking density can be controlled at 2,000 ~ 3,000, and the stocking density of shrimps with a size of 667㎡ can be appropriately increased.

Because shrimp bully the weak and fear the big, the specifications of fry stocked in the same pond should be neat. Avoid excessive temperature difference between water and seedlings, and pool in the evening or at dawn. Before releasing the seedlings, slowly add a small amount of pond water into the seedling transport container until the water temperature of the container is close to that of the pond water, and then gently pour the shrimp seedlings into the pond water.
