### Instruction: What is a fishing vessel?
### Input: A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal, and recreational fishing.

According to the FAO, in 2004 there were four million commercial fishing vessels. About 1.3 million of these are decked vessels with enclosed areas. Nearly all of these decked vessels are mechanised, and 40,000 of them are over 100 tons. At the other extreme, two-thirds (1.8 million) of the undecked boats are traditional craft of various types, powered only by sail and oars. These boats are used by artisan fishers.
### Response: A fishing vessel is a boat or ship that is used for recreational or commercial activities such as fishing, inner-tubing, transportation or just for fun.
