Each fish spot can have 1-3 fish, if you get lucky and find a lot of fish spots with 3 fish this can be done very quickly. The Pack-a-Punched GS45s are best for doing this quickly, you'll know how many fish you have killed within a single spot based on the drops that come up out of the water, one drop for each fish.

Once 50 total fish have been killed, the player will immediately be rewarded with every perk in the game. If you ever lose those perks, you can gain them all back simply by killing a couple more fish, not the full 50 again.

Fishing Spots can be easily indentified by the bubbles on the surface of the water, indicating their are fish underneath
