Fishing is not a sport, but a necessity for many people; fish form an important part of their diet. Characters with this skill are quite canny with a hook-and-line or net. If properly equipped, characters can catch fish from any waters, but the gamesmaster must decide how long it will take to catch the amount of fish required - this should vary from place to place or day to day. A good rule of thumb is that it takes D4 hours to catch enough fish to keep one person alive for one day.
Fishermen know where to find specific sorts of fish and what habitats different fish prefer. Catching rates and probabilities are at the discretion of the gamesmaster; fishing in winter, for example, should be difficult or even impossible.
