Energetic cost of spawning in male and female Atlantic salmon ( Salmo salar L.)
Energetic expenditure during spawning of male and female 1 ‐sea‐winter Atlantic salmon, Salmo salar L., was measured. Before spawning, the somatic energy content per unit weight did not differ between the sexes. The testes content offat was 0.24, of carbohydrate 8.89, of water 1.21 and of ash 1.61 t...
