1. Salmon: Salmon are anadromous fish that spend part of their lives in freshwater and part in saltwater. They lay their eggs in freshwater rivers and streams, and the young salmon hatch and migrate downstream to the ocean.
2. Trout: Trout are also anadromous or freshwater fish that lay eggs. Different species of trout have specific spawning habits and locations, but they typically lay their eggs in gravel or rocky substrates in streams or rivers.
3. Carp: Carp are freshwater fish commonly found in lakes, rivers, and ponds. They are prolific egg-layers, and females can produce hundreds of thousands of eggs at a time. Carp eggs are sticky and adhere to vegetation or other surfaces in the water.
4. Goldfish: Goldfish are ornamental fish often kept in aquariums and ponds. They are a type of carp and also lay eggs. Goldfish eggs are small and transparent, and the females scatter them in the water.
5. Betta fish: Betta fish, also known as Siamese fighting fish, are popular aquarium fish. Male betta fish build bubble nests at the water's surface and coax the female to lay her eggs in the nests. The male betta then guards the eggs and cares for the young until they hatch.
6. Catfish: Many catfish species lay eggs. For example, the corydoras catfish buries its eggs in the substrate, while the upside-down catfish glues its eggs to the underside of leaves or other surfaces in the water.
7. Cichlids: Cichlids are a large and diverse group of fish, many of which lay eggs. Some cichlid species, like the angelfish and discus, are popular aquarium fish known for their elaborate parental care. They guard and fan their eggs and later protect their young until they become independent.
8. Swordtails: Swordtail fish are livebearers, but some species, like the platy and molly, lay eggs. The eggs of platy and molly fish are small and develop internally before being released into the water.
9. Medaka: Medaka fish, also known as rice fish, are small freshwater fish native to East Asia. They are egg-layers and scatter their eggs in the water.
10. Killifish: Killifish are a group of freshwater fish that inhabit various environments. Many killifish species are annual fish that lay eggs that can withstand harsh conditions, such as drying out, and hatch when water is available again.
These are just a few examples of the many fish species that lay eggs. The reproductive strategies and egg-laying behaviors of fish vary greatly, reflecting the diversity of fish species and their adaptation to different habitats.
