摘要: The objective was to assess neural, behavioural responses and product quality in farmed sea bass (Dicentrarchus labrax) upon electrical stunning seawater. sinusoidal 50 Hz or pulse square wave alternating 133 current induced a general epileptiform insult with of 3.3±0.2 3 A dm?2, respectively, for 1 s head tail total duration the 48±34 23±11 s. After stunning, electro-cardiogram revealed fibrillation ceased showed malfunction. Product assessed group electrically stunned, followed by chilling ice water controls were only chilled water. pH fillets 0.1?0.2 lower (P
