Notes on crabs:

they dont spawn naturally unless there is a pot in the water
each pot holds 16 crabs
every 2-4 minutes a crab spawns in the pot
there might be a speed restriction
pots can be stacked 7 high before crabs stop appearing in them (when on sea floor), or about 5m from the sea floor where pots work
pots are places with the hole on the top
crabs when released say alive. for how long, no clue
the closer to the shore you are. the less distance from the seafloor you have for pots to catch crabs
grabbing crabs straight from the pot kills them
sleeping speeds up crab pots

fishing rod number is for the length of the lure. not the length of the line
great way to know when your fishing rod is under to much stress is the angle its at.
