J _max and K _m values generated by DL‐ [ 14C]Met flux assays along the gastrointestinal tract of rainbow trout in the Na ⁺ buffer, substrate DL‐Met gradient from 0.2 to 20 mmol/L. Values were expressed as mean ± SEM (n = 21–27). Asterisks represent significant difference in J _max between ploidies (Student’s t‐test, *P < 0.05).
