Fame
You may never get the fame you so richly deserve, except for the local crab shack's signature dish, "Fish Pie a la Joe." However, there's room for improvement in the field, and if you dream up a more efficient way to transport stock or patent a cutting edge water pump, you might swim to the head of the school. And your ultimate goal, of course, should be to get into the "Fish Culture Hall of Fame."
Remember, you swim in the wake of those who came before. Seth Green (not that Seth Green) isn't called "Father of Fish Culture in North America" for nothing...in the late 1800s he was the White House's "go-to guy" for fish matters, and was one of the first Americans to try rearing and transporting captive fish (source). Spencer Fullerton Baird, the first Fish Commissioner and naturalist extraordinaire, expanded scientific knowledge by creating a collection of fish specimens at the Smithsonian Institution. Harry Westers revolutionized hatchery equipment and created formulas to accurately monitor water quality (source).
They aren't famous in the Bradjelina sense, but they're on Wikipedia, so that's something...right?
