Research shows that salts dramatically increase shrimp growth rates

Researchers in have determined positive effects from supplementing shrimp diets (Penaeus vannamei) with sodium salts (formate, acetate, lactate, propionate, butyrate, fumarate, succinate and citrate).

Researchers in Mexico and Brazil have determined positive effects from supplementing shrimp diets (Penaeus vannamei) with sodium salts (formate, acetate, lactate, propionate, butyrate, fumarate, succinate and citrate). 

In a growth trial, the highest final weights were in shrimp fed diets supplemented with fumarate, succinate, butyrate and propionate, increasing 53%, 46%, 38% and 29% respectively, compared to the control. Shrimp that were fed diets with fumarate, digested more feed and had a feed conversion ratio 23% higher than the control shrimp. Shrimp survival did not differ among treatments. The researchers concluded that organic salts in the diet modify digestive enzymatic activity and protein digestibility.
