Well, there are plenty of words in Greek which relate to fishing, mostly because fishing was a big part of life in ancient Greece (and modern Greece, as well!).
For example: δυσαγρέω (dysagreo) means to “have bad sport in fishing”
and ἐπαγροσύνη (epagrosyne) means “good luck in fishing”
There are even specific words for those who catch fish in specific ways, and for people who sell different kinds of fish!
Words like this are so prevalent in Greek both because of the necessity for such words in a culture where fish is a main protein source and because of Greek’s ability to combine words so easily.
Greek as a language is very adaptable, and prefixes, suffixes, and conjoined words were a major part of the language in ancient times. So finding words that mean very specific things, especially in concern to fishing (or battle or sex), is understandable.
