list all the fish eatable in atlantic ocean waters. especialy those
consumed in spain.

The number of species of edible fish eaten in Spain probably runs to
the hundreds, the number of edible fish in the Atlantic Ocean is at
least double that number. You may wish to increase your price for a
researcher to consider answering your question. Otherwise, if no
researcher responds,if you wish, I will provide a list of up 30-40 of
the most common species.
