Sex Ratio and Potential Fecundity of Atlantic Salmon (Salmo salar L.) Caught by Anglers on the Elorn River (Northern Brittany, France) during 1979 and 1980
Analysis of the sex ratio of angling Atlantic salmon catches from March to mid-June on the Elorn river in 1979 and 1980 showed a majority of females among the spring salmon population. Comparison between serodiagnostic technique and visual observations of gonads indicated that the former method prov...
