Wheat Gluten: A reliable protein and binder for fish feed

Wheat gluten is a common ingredient in modern aquaculture diets, valued for a combination of nutritional and functional advantages. It isn’t a magic ingredient, but it consistently supports efficient feed production and healthy fish growth. One of its best-known traits is its strong binding ability earning it the occasional nickname “super glue.” This natural binding property allows many feed mills to reduce or even eliminate synthetic binders. 

These qualities make wheat gluten a flexible ingredient for a range of species. It performs reliably in both cold-water and warm-water fish whether the diet is for trout in cool streams or tilapia in warm ponds. Functionally, wheat gluten strengthens the physical quality of feed during extrusion or pelleting: 

• It acts as a natural binder, improving pellet firmness. 

• It reduces breakdown in water, minimizing nutrient loss. 

• It improves water stability, a key requirement for shrimp feed. 

The result is less dust, less feed waste, and cleaner tanks or ponds. 

Wheat gluten also contributes to digestive health: 

• Its high digestibility helps reduce intestinal stress. 

• It can support a balanced gut microbiome. 

• It contains glutamine, an amino acid important for maintaining intestinal integrity. 

• Its neutral flavor profile also helps carry other attractants, aiding feed acceptance. 

As aquaculture continues to expand, the industry needs dependable alternative proteins that support both performance and sustainability. Wheat gluten fits well in that role offering consistent quality, strong functionality, and a reliable supply.
