How to apply Bacillus bacterial strains in fish and shrimp ponds
Application of Bacillus bacterial strains in fish and shrimp ponds
(Agricultural Wealth Network) Feedback on the use of Bacillus bacterial strains in Tianjin:
1. The condition of a fish pond in Beichen District, Tianjin before use: among the algae in the water, green algae accounted for 20%, diatoms accounted for 10%, and euglena accounted for 50%; water transparency was very low, and there was a grayish-white viscous oil film on the water surface at the downwind edge of the pond, and the fish fed poorly in the morning.
Treatment method: At around 9 a.m., take half a bucket of water from the upper surface layer of the pond, add 3 bottles of freeze-dried bacterial strains and 3 jin of brown sugar, then place the bucket indoors and culture it statically for 24 hours, and apply it at around 9 a.m. the next day.
Application effect: After using the bacterial strains for 2 days, water testing showed that euglena accounted for 10% of the algae in the water, green algae 50%, and diatoms about 20%, and the farmer reported: water transparency increased, the water became clear, and the fish resumed normal feeding in the morning.
2. A shrimp pond in Baodi, Tianjin had just been stocked with shrimp fry 15 days earlier; the water was clear and lean, with very few algae, and the ammonia nitrogen content in the water was very high, at about 0.5.
Treatment method: On the first morning, use detoxification anti-stress essence liquid (1 bottle/3 mu) and splash it over the whole pond, then splash fertilizer-water algae source (1 bottle/6 mu) + Green Water No. 1 (1 packet/3 mu) over the whole pond, then put the Bacillus bacterial strains into brown sugar and soak for 24 hours, and on the second day splash the Bacillus bacterial liquid soaked on the first day over the whole pond.
Application effect: On the fifth day, the water turned yellow-green, dominated by green algae and diatoms, and all water quality indicators were normal.
Summary: When the freeze-dried Bacillus agent is prepared with pond water for immediate use, the bacterial cells are especially fresh, so their vitality is also especially strong. This bacterial liquid was activated with pond water, and before being splashed into the pond, the bacterial cells already had strong adaptability to the pond water, so the application effect of Bacillus bacterial strains in ponds is relatively good.
