If you are haivng a problem understanding the answers, do not start a new thread, otherwise the same people who were helping you originally may not know you are still having a problem.
To insert multiple rows of data you cannot use the VALUES clause of the INSERT statement (as it tells you in the documentation if you read it).
You need:
INSERT INTO ...
SELECT ... FROM ... UNION ALL
SELECT ... FROM ... UNION ALL
SELECT ... FROM ... etc.or, in your case you would need something more simply like
insert into FISH_FAMILIES(SCIENCE_NAME,ARABIC_NAME,LATIN_NAME,IS_FAMILY)
select fs.family, fs.arabic_description, fs.latin_description, fs.is_family
from   fish_species fs
