Influence de quelques paramètres du milieu d'incubation sur la survie d'alevins de saumon atlantique, Salmo salar L., en ruisseau expérimental. Influence of some Environmental Parameters upon Survival during Embryonic Development of Atlantic salmon, Salmo solar L., in an Experimental Stream Channel
Abstract The effect of some environmental parameters of the redd (substrate composition, interstitial dissolved oxygen concentration) upon survival of Atlantic salmon embryos was studied in a large artificial stream channel. Batches of 3000 eyed eggs were buried 0.25 m deep in the gravel substrate o...
