Physiology and Survival of Atlantic Salmon following Exhaustive Exercise in Hard and Softer Water: Implications for the Catch-and-Release Sport Fishery

摘要: Abstract This study examined the influence of environmental water hardness (40 mg/L versus 100 CaCO3) on physiology and survival exhaustively exercised Atlantic salmon Salmo salar. Cannulated provided blood samples at rest 0, 1, 2, 4, 8 h postexercise, whereas white muscle were acquired from noncannulated 0 4 postexercise. Exhaustive exercise resulted in significant metabolic, acid–base, electrolyte disturbances hard (about 95 water, although postexercise was 100%. For resting salmon, physiological status those softer 40 similar to that water. In however, exhaustive caused a significantly greater elevation lactate larger acid–base disturbance compared with fish Postexercise w...
