Makes seasonal migrations
Group spawning
No significant migration pattern
External fertilization
Hairtails are known to migrate long distances during spawning season, moving from offshore areas to coastal waters.
Hairtails gather in large groups to reproduce, and the males and females release their eggs and sperm simultaneously.
Hakes are known to migrate. They often move to different areas in search of food or to reproduce. The exact migration patterns can vary depending on the species and region.
Hakes have specific spawning seasons, which vary depending on the species and geographic region. During spawning, large groups of hakes gather in specific areas to reproduce.
Some species migrate between freshwater and saltwater habitats
Males use elongated lower jaws to attract females
Non-migratory
Unknown
Long-distance migration
There is limited information on the migration patterns of halosaurs, but they are thought to undertake vertical migrations in search of food.
During mating, male halosaurs release sperm into the water column, where it is picked up by the females to fertilize their eggs.
Monogamous pair bonding
Some species migrate long distances
Mating occurs during the summer or early fall
Females lay eggs on the seafloor
Hardhead Catfish do not have a regular migration pattern.
During reproduction, males will chase and nudge females to stimulate egg release. Females can lay up to 50,000 eggs at a time.
Limited migration
Spawning in rocky areas
Egglayers
Hawkfish are monogamous and form pairs during the breeding season
Migratory
Spawning in large aggregations
Herring smelts have a migratory pattern, moving between coastal areas and deeper waters for spawning.
During reproduction, the males and females form large schools and release their eggs and sperm simultaneously.
