Give a man a fish and he eats today, give a man some farmable land and he can plant some soybeans which in turn can be exchanged for money. This money can then be traded for various goods and services including more fish if one desired, but honestly if you have farmable land that can support enough soybeans to sell at a healthy profit then you are likely not near a great source of seafood, so you should probably skip on the fish and eat something else for dinner tonight. Maybe a nice piece of lean pork with a side of peas? Of course if you had planted some peas as well this would be ideal.
