That is one thing i would be most excited to see in a future update, more aquatic life both fresh water and ocean. There's so many interesting aquatic creatures and the idea of being able to encounter a colossal squid on a dive would be crazy! the latest update is a good start on the seas but I definitely have a freshwater fish shaped hole in my heart right now lol. Another cool addition would be freshwater fish spawning times, like the salmon runs in Alaska where for a month or so the fish are extremely prevalent and can be caught in high number to preserve but it takes some planning and forethought to make a set up to catch them in large numbers.
