Significance of Mature Male Parr in a Small Population of Atlantic Salmon ( Salmo salar )
The spawning population of Atlantic salmon, Salmo salar, (mature male parr and adults (anadromous salmon)) were assessed in the River Baevra, central Norway, when the river was treated with rotenone in November 1986. The spawning population of adults consisted of 15 males and 19 females. The spawnin...
