Fecundity of Atlantic Salmon ( Salmo salar) from Two Maine Rivers
Estimates of numbers of eggs in 164 hatchery-spawned Atlantic salmon (Salmo salar) from two Maine rivers ranged from 3528 to 18,847, and egg number per pound of total body weight from 523 to 1385. Sample autopsies of 10 salmon revealed that artificial spawning removed an average of more than 97% of...
