People in different parts of the world are not always referring to exactly the same things when they use the words “trap” and “pot”. In general, traps are large structures fixed to the shore.
Pots are smaller, movable traps, enclosed baskets or boxes that are set from a boat or by hand.
* Traps set out of the water to catch fish such as flying fish that jump off the tops of waves and glide over the surface when in danger; these can be box-shaped, rafts, boats or nets (“veranda” net types); scoop nets are sometimes used for making fish jump. Pitfall traps can be used for marine animals that migrate over land, such as coconut crabs.
