Water quality requirements mainly use unpolluted surface water from large water bodies such as rivers, lakes and reservoirs as water sources, and groundwater can also be used as water sources. Freshwater lobster has strong adaptability, and the pH value of water can survive in the range of 6.10 ~ 9.33, but it is suitable to be 6.5 ~ 9.0, and it is best to be neutral and alkaline to facilitate the rapid growth of lobster. Although freshwater lobster is resistant to hypoxia, its growth rate and survival rate will be affected if it is in a state of low dissolved oxygen for a long time. The water quality should also be prevented from being polluted by heavy metals, pesticides, herbicides, oil, methane, etc., and micro-running water or regular fresh water should be adopted in aquaculture to promote growth.
Shrimp fry throwing and daily management Shrimp fry throwing should be carried out in the early morning or evening on sunny days. Before throwing, a small amount of pond water should be slowly added into the seedling transport container, and the water temperature should be adjusted until the water temperature in the container is close to that of the pond water. The stocking density is 7.5-9.0 shrimps per square meter, and the specifications of shrimps stocked in the same pond are consistent. Due to the fast growth, vigorous metabolism and large oxygen consumption of freshwater lobsters, the water quality of shrimp ponds should be kept fresh frequently, and water15 ~ 20cm is generally added every week to make the water quality lively and have enough dissolved oxygen. Bait feeding should be fixed-point, fixed-time, quantitative, diversified as far as possible, fed once every morning and evening, and bait should be thrown at the shallow water side of the pond.
