The specialized organic bio-fertilizer for *Penaeus vannamei* (whiteleg shrimp) has been jointly developed by Zhejiang Zhefeng Chemical Fertilizer Trace Elements Co., Ltd., Zhejiang University, and the Zhejiang Academy of Agricultural Sciences. This eco-friendly product is made from high-quality organic materials such as chicken manure, cow dung, rapeseed cake, and fish meal, which are fermented to create a nutrient-rich fertilizer. It helps quickly improve water quality, balance the pH levels in the pond, and enhance the overall aquatic environment. The fertilizer is especially recommended for use before releasing juvenile shrimp, aiding in the preparation of a suitable breeding environment and maintaining optimal water conditions throughout the growing cycle. It is specifically designed for freshwater aquaculture systems.
**Usage Instructions:**
(1) Before introducing shrimp seedlings, apply 20–40 kg of the fertilizer per acre of water with a depth of 1 meter to enrich the water body.
(2) For topdressing, apply approximately 10 kg per mu to maintain a water transparency of 30–40 cm.
(3) The frequency of topdressing should be adjusted based on factors like water temperature, water quality, and the existing fertility and clarity of the pond. Typically, it is applied every 5–7 days.
(4) It is best to apply the fertilizer during sunny mornings. Dissolve the required amount in water first, then evenly sprinkle it into the pond while operating the aerator to ensure proper mixing and oxygenation.
This fertilizer not only promotes healthy shrimp growth but also supports sustainable aquaculture practices by reducing reliance on chemical inputs. Its natural composition helps maintain a balanced ecosystem in the pond, leading to better yields and improved water quality over time.
