The Fisher is a machine added by MineFactory Reloaded. When placed above water and powered, the Fisher will produce Raw Fish and automatically pump it out into an adjacent Chest or BuildCraft Pipe. Like all MineFactory Reloaded machines, the Fisher will accept either BuildCraft MJ or Industrial Craft 2 EU, though EU will display as MJ in the Fisher's GUI.
For the Fisher to work most effectively, the pool needs to be at least 3x3 with a depth of two blocks. The Fisher requires 400 Work to harvest one fish; this is about 2,000 EU or MJ. At a power consumption of 1 EU/t, it takes the Fisher one minute and forty seconds to harvest a fish. The Fisher has a cooldown of 200 ticks after every fish.
