Mutations with a similar multiplier
Using the Diurnal mutation
A fish carries one mutation at a time and the multiplier applies after the weight price, then the game rounds up. The same ×7 is worth far more on a heavy, high price-per-kg fish than on a small one, so check your catch in the sell calculator before you sell. Compare it with every other multiplier on the mutation list.
