Abstract

Laboratory and field studies have shown that the survival of salmonid fish eggs and alevins is dependent upon the supply rate or flux of dissolved oxygen through gravel beds used for spawning. Although there have been a number of studies concerned with North American species there are few data for Atlantic salmon (Salmo salar) and the brown trout (S. trutta). For this study intragravel seepage velocities and dissolved oxygen concentrations have been measured throughout the incubation period in spawning gravels utilized by brown trout (Salmo trutta). Variation in the hatching success of batches of trout and salmon (Salmo salar) can, in part, be attributed to a critical threshold of oxygen flux through the gravels.
