Frequency of Multiple Paternity in the Spiny Dogfish Squalus acanthias in the Western North Atlantic
Multiple paternity (MP) has been shown to be widespread in elasmobranch fishes although its prevalence and the number of sires per litter vary considerably among species. In the squaloid shark Squalus acanthias , MP has been reported, but whether it is a common feature of the species’ reproductive s...
