Recovery from exhaustive swimming and its effect on fillet quality in haddock (Melanogrammus aeglefinus)
Wild haddock (Melanogrammus aeglefinus) of commercial size (0.8–2.49 kg, 45–60 cm) were swum to exhaustion in a large swim tunnel and then allowed to recuperate for 0, 3 or 6 h, to investigate the effects of exhaustive swimming on blood glucose, blood lactate and post mortem development of fillet qu...
