Fish

Fish are first introduced in Monster Hunter 3. A variety of different fish species exists and can be generally classified as migratory, natatorial, or carnivorous fish. Fish are the food source for massive Leviathans such as Lagiacrus. If harmed enough they will swim away. However, if damaged enough and then speared with a fishing harpoon, they can be carved. Sharqs and Catfish will actually limp when they are weakened.

Tips

 * An easy way to get Sharqskin is to do the first rank Sunken Treasures quest. There are more sharqs around the water areas, making it easier to farm them.
 * An easy way to get Velvety Hide is to do the third rank The Deadliest Catch quest (because on most quests there are no catfish spawns) because it has a sub-quest to slay 3 catfish, therefore making them spawn on the map.
