Most fish reproduce using external fertilisation - the female lays her eggs, and the male then covers them with sperm, fertilising them. Some fish, however, use internal fertilisation. Sharks are an example. Males sharks have paired copulatory organs called claspers, one of which is inserted into the female's cloaca, depositing sperm inside her. In some species, eggs are then laid and will hatch after an incubation period, but in others the eggs are retained within the mother's body until the young are fully developed, when they are born alive.

Why can fish no longer be considered a renewable resource on Canada's coasts?
mainly because we over fished the seas and there isn't much fish left in it nor do we really give fish a chance to reproduce themselves we just take them out of the water. So fishes don't reproduce and they don't renew what is lost or what we took away
