When tilapia fish are raised in salty water that's low in potassium, adding taurine to their food seems to boost certain genes in their gills that help manage water and salt levels — but giving them extra potassium at the same time cancels out this benefit, showing that different types of salts and nutrients can interact in tricky ways.

Taurine and/or inorganic potassium as dietary osmolyte counter the stress and enhance the growth of GIFT reared in ion imbalanced low saline water

The study found that adding taurine to fish food helps fish handle salty water better by changing gill proteins, but adding potassium at the same time reduces this benefit, which matches what the claim says.

Similar Assertions

Giving extra potassium in their food helps farmed tilapia handle salty water better, reduces stress on their gills, and saves energy — and 0.6% potassium in the feed works best.

Giving certain fish extra potassium and taurine in their food might help them handle salty water better by reducing stress in their gills and liver.

When farming a type of tilapia in salty water that’s low in potassium, giving the fish a mix of a little potassium and taurine in their food helps them grow the most—way better than giving just one or more potassium.
