Mog juice is obtained with the "extract from raw fish" command at the fishery. This requires a captured live moghopper and a barrel and is done by a dwarf with the fish dissection labor enabled. Each moghopper yields 5 units of mog juice, and each unit has a value of 50☼ per unit. Extraction kills the moghopper.
Mog juice is currently the only obtainable product from fish extraction, but due to the rarity of moghoppers, it is not a staple of the dwarven diet.
