This mod is now maintained by Zuxelus here: [1.7.10] Ztech - Collection of AddonsA complete rewrite of the old Electric Fishing Rod addon from version 1.90. In this version, there are two types, a low tier one that can hold 100k eu, and an advanced one that can hold 1 million eu. The advanced one also charges considerably faster. It takes 5000 eu to use, and will pull up a fair number of fish by first zapping them with a teslacoil, and then dragging them back in with the magnetizer. Fish are actually highly magnetic, due to the high concentrations of metals contained in most mobs in Minecraftia. Please note that hitting anything alive with an electric fishing rod will cause a short circuit, dealing heavy damage to you and even heavier damage to whatever you hit. The advanced circuitry used in the advanced fishing rod concentrates that damage more towards your enemy and less towards you, however, if you hit anything with either rod, you will void your warranty.
Imgur is being silly. Use NEI for the moment. It's an energy crystal, teslacoil, and a magnetizer for the regular (diagonally from lower left to right, in that order) and a shapeless electric rod, lapotron, advanced circuit for the advanced one.
2.0.2: The fishing rods actually cook the fish now. Also, changed the fishing rods to use twice as much EU, and the regular one only gives 0-6 fish as opposed to 0-8
2.0.1: The fishing rods now cook the fish as they electrocute them.
In order to use it to fish, you have to be standing in the water, and right clicking water blocks less than a block away from you. Otherwise, it won't work.
