Successful case of Water quality Control in Old Shrimp Pond

(agricultural Wealth net) there are many aquaculture ponds in Shandong area. Because the water cannot be drained and the bottom can not be cleared, the silt at the bottom of the pond is relatively thick, coupled with more residual bait and shrimp feces in the later stage, which can easily cause the bottom to stink, and the water color thickens and blackens, resulting in an increase in the incidence of shrimp. Boss Chen's shrimp pond is the above situation, the success rate of breeding is very low. This year, Boss Chen treated it according to the following methods. At present, the water quality of the four ponds is good, and the shrimp is growing well.

1. Change the bottom regularly and use the bottom modification products every 10 days or so: the alternate use of bottom solution (chemical) and bottom clear (biological) can not only change the problem of bottom odor, but also make beneficial microorganisms colonize at the bottom of the pond.

2. After the bottom modification of water transfer, soak and sprinkle with water retention probiotics per bag of 2 mu rice or Bacillus strains per bottle of 6 mu rice for 24 hours, and the water quality has been in a good state.
