Data from: Spawning behaviour of Arctic charr (Salvelinus alpinus): spawning synchrony, vibrational communication and mate guarding
A mismatch between male and female gamete release in external fertilizers can result in reduced or failed fertilization, sperm competition and reduced paternity. Here, spawning behaviour of free-living Arctic charr (Salvelinus alpinus) was video recorded, and their reproductive behaviour was analyse...

A mismatch between male and female gamete release in external fertilizers can result in reduced or failed fertilization, sperm competition and reduced paternity.
