[Case Selection] Successful Treatment of Oil Film Water in Shrimp and Crab Mixed Pond
1. Case details
Venue: Magang Breeding Area, Huchang Town, Xiantao City, Hubei Province
Breeding varieties: shrimp and crab mixed culture
Farming area: 12 mu of Huanggou water depth 120cm, board field water depth 20cm, average about 70cm
Water quality index: PH:8.3 ammonia nitrogen: 0.5 nitrite: 0.04
Description: There are too many organic matter residues at the bottom of the aquaculture pond, poor bottom quality and oil film on the water surface. Water quality is thin.
2、Treatment Scheme
In the morning, use strong decomposition to improve the bottom quality, 3 mu per package, and in the afternoon sprinkle super decomposition (6 mu per bottle) to decompose the oil film of the water body. On the second day, EM Jinlu (3 mu per bottle) was used to adjust the water quality. Diatom was 10KG (8 mu per pack) and fertilizer was used.
3、Effect feedback
The oil film basically disappeared the next morning, and the water body quickly turned dark brown after fertilization.
4、Case analysis
Due to improper management of water body and bottom matter, enrichment of organic matter in pond, residue of feed in pond, decay of aquatic plants, imbalance of bacteria and algae and other reasons, a large amount of oil film appears on the water surface. Strong decomposition bottom modification can effectively decompose excess organic matter and improve bottom matter. Super-strong solution can effectively break water permeability and remove oil film. EM Jinlu and diatom regulate the bacterial and algal phases in water bodies and improve the breeding environment.
