Important Considerations:
* Location: The specific fish species you'll find will vary greatly depending on the specific location within Spain. The Mediterranean Sea is very different from the Atlantic Ocean, and freshwater habitats are also diverse.
* Depth and Habitat: The depth of the water, the type of seabed, and the presence of currents all influence which fish species are present.
* Season: Fish migrations and breeding seasons can also affect which fish are available at certain times of the year.
To learn about specific fish species in a certain area, it's best to consult local fishing guides, websites, or experts.
