Ok, so after seeing a few games on naval maps, I realized that many naval maps and hybrid maps (land and sea, like hyrcanian shores, lake, continent) do not have enough fish to justify making fishing ships.
Take as an example Aegean Sea:
The bottom two players don't have a single fish accessible, and the top few players only have a handful, with some of those fish being close enough to the shore. In this case, players may only be able to gather 3000 food with an investment of not only as much as 500 wood (dock + boats), but also lots construction and walking time.
This is not enough fish to justify making fishing ships and it means naval gameplay is only relevant for controlling passage to the other side. It also means there is rarely any fish to kill with ships, and if there were fishing ships, they would have already gathered most of the accessible fish.
Also, if you look at lake, you would see a map that should be pretty enjoyable, but because there are such a small number of fish in the lake, the middle lake is basically just an obstruction unless you use it for transport and siege ships.
Here is Aegean sea after adding the fish:
I didn't apply the same exact change to all maps. For maps where there was a comically small amount of fish, I added plenty, but for maps like continent, I added just enough to make fishing worthwhile, but not mandatory.
Thoughts?
