Blood lactate loads of redthroat emperor Lethrinus miniatus associated with angling stress and exhaustive exercise
journal contribution
posted on 2023-05-18, 13:20 authored by Currey, LM, Heupel, MR, Simpendorfer, CA, Clark, TDBaseline, post-angling and maximum attainable blood lactate concentrations were measured for the fishery species redthroat emperor Lethrinus miniatus to gain insight into the condition of fish released following c. 30 s angling and <45 s air exposure. Mean ± s.d. baseline blood lactate was 1·5 ± 0·6 mmol l−1, which increased and plateaued around 6 mmol l−1 at 15–30 min post-angling. These values were significantly lower than those obtained from fish maximally exhausted with a prolonged chase and air exposure protocol following capture (10·9 ± 1·8 mmol l−1), suggesting that L. miniatus is not maximally exhausted during standard angling practices.
