Here's a couple ideas I'd like to be considered to make lakes and coastal waters more appealing.
1. Farming options - Water edition
A. Molluscs farm.
Requires shallow fresh (mussel or lake snails) / salt (oyster) water. Slowly spawns molluscs over time. Allows to slowly raise the quality, for better molluscs and pearls.
B. Algae farm.
Grow kelp (and possibly more types of new algae). Could work similarly to crops or gardening.
C. Fish farm.
A "rabbit hatch for fish". Needs to be placed in deep water. Put in some fish (same kind), let it reproduce. Different fish require different water environments. Allows to slowly raise the quality through fodder, as well as farming fish eggs.
D. Crustacean farm.
Same as the Fish farm, but for crabs, lobsters, and shrimps. Might need a way to kill them safely though.
2. More aquatic animals
I'm not talking about land animals that can swim, like beaver, otters, and walruses. But rather fully aquatic ones (like the orcas and whales, but more common and less "end-gamey")
Critters: octopods, rays, and such.
Neutral animals: sea turtles, dolphins, narwhals, and so on.
Hostile animals: from small ones like water snakes, to larger ones like sharks or alligators.
New animals would also need useful recipes for their parts.
I hope with the new experimental world coming soon, we'll see some addition to the water enviroments, given they take up a lot of map space but right now are still kind of poor in content (other than some forageables).
