The “Code” for Healthy and Efficient Growth of Fish and Shrimp — Potassium Diformate

Potassium diformate is widely used in aquatic animal production, mainly fish and shrimp.

The effect of Potassium diformate on the production performance of Penaeus vannamei. After adding 0.2% and 0.5% of Potassium diformate, the body weight of Penaeus vannamei increased by 7.2% and 7.4%, the specific growth rate of shrimp increased by 4.4% and 4.0%, and the growth capacity index of shrimp increased by 3.8% and 19.5%, respectively, compared with the control group. The daily growth rate, feed efficiency and survival rate of Macrobrachium rosenbergii could be improved by adding 1% of potassium di Potassium diformate to the feed.

The body weight gain of Tilapia increased by 15.16% and 16.14%, the specific growth rate increased by 11.69% and 12.99%, the feed conversion rate decreased by 9.21%, and the cumulative mortality rate of oral infection with Aeromonas hydrophila decreased by 67.5% and 82.5% respectively after the addition of 0.2% and 0.3% of potassium di Potassium formate. It can be seen that potassium di Potassium formate has a positive role in improving the growth performance of Tilapia and resisting disease infection. Suphoronski and other researchers found that Potassium formate can significantly increase the daily weight gain and growth rate of Tilapia, improve feed conversion rate, and reduce mortality due to disease infection.

Dietary supplementation of 0.9% potassium di Potassium diformate improved the Hematology characteristics of African catfish, especially the hemoglobin level. Potassium diformate can significantly improve the growth parameters of young Trachinotus ovatus. Compared with the control group, the weight gain rate, specific growth rate and feed efficiency increased by 9.87%, 6.55% and 2.03%, respectively, and the recommended dosage was 6.58 g/kg.

Potassium diformate has an active role in improving sturgeon growth performance, total immunoglobulin, Lysozyme activity and total protein level in serum and skin mucus, and improving intestinal tissue morphology. The optimal addition range is 8.48~8.83 g/kg.

The survival rate of orange sharks infected by Hydromonas hydrophila was significantly improved by the addition of Potassium formate, and the highest survival rate was 81.67% with 0.3% addition.

Potassium diformate plays an active role in improving the production performance of aquatic animals and reducing mortality, and can be used in aquaculture as a beneficial feed additive.
