Hematological parameters associated with parasitism in pike, Esox lucius caught from Anzali wetland.

This study involved 120 pike, Esox lucius, captured from Anzali wetland. Parasite fauna were identified in captured fish. Also, changes of haematological parameters were compared both infected and uninfected fish.

Variations of physiological and innate immunological responses in goldfish (Carassius auratus) subjected to recurrent acute stress.

This study was undertaken to investigate the influence of repeated acute stress on the physiological status and non-specific immune response of goldfish, Carassius auratus. The acute stress was a succession of a 3 min-chasing period followed by a 2 min-air exposure. The goldfish in triplicate tanks were subjected 3 times daily to this stress for one (S3) or three (S9) days.
