Estimated Escapement of Atlantic Salmon (Salmo salar) for Maximum Smolt Production in Rivers of Different Productivity

摘要: Smolt production at different egg deposition densities is estimated from data on survival rates and space requirements of juvenile Atlantic salmon (Salmo salar) reported in the literature. Average maximum smolts to be approximately 5/100 m2 for 2+ smolts, 2/100 m2 3+ 1/100 m2 4+ smolts. Minimum depositions recommended these numbers are 220/100 m2, 165–220/100 m2, 80/100 m2 each age respectively. The escapement adults required produce must observed average weights returning females a fecundity between 1650 1760 eggs/kg female. With exception Ungava rivers, smolt any particular river can number days per year which water temperature reaches or exceeds 7 °C.
