'''Crab pots''' are floated on the shores of bodies of water (lakes, ponds, rivers, or the ocean) and primed with [[bait]] in order to catch fish. Any type of bait (standard [[Bait (item)|Bait]], [[Wild Bait]], [[Magnet]]) can be used in a crab pot, but there is no benefit to using specialized types of bait: crab pots never produce double fish or treasure. Players with the [[Skills#Fishing|Luremaster profession]] profession don't need to add bait.

Unless you have the [[Mariner]] profession, the following [[trash]] items can be obtained by putting a crab pot in any type of water, which includes the river, the lake and the ocean. The chance of trash appearing is 2038%, <ref name="crabpot_chance" /> regardless of luck or fishing skill; all trash items are equally likely to appear. Trash can be [[Recycling Machine|recycled]] into useful items.

<ref name="crabpot_chance">Crab pot contents are determined by <tt>CrabPot::DayUpdate</tt>. For mariners, there is no chance of junk, and all creatures are equally likely. For non-mariners, there is a 20% chance of junk, then each creature is checked sequentially using the chances specified in <tt>Fish.xnb</tt>. One result of this algorithm is that the actual chance of finding a given creature is smaller than the value in the input file, because it can only be found if junk items and all previous creatures failed their tests. If no creature is found, the code falls back to trash; this adds 18% more chance of trash (for both ocean and freshwater crab pots).</ref>
