Hello Qenan. I don't know a lot about working with an electroshock unit as I was just taking photos to document the work on that outing. However, I can tell you a couple of bits of info that may be useful to you. First, I have photographed quite a bit of fish survey work and, most times, I would say that a seine net actually captures many more fish than an electroshock unit. The problem with the unit is that they don't work all that well in deeper water and you must have a second person along to net the fish as they are shocked. There are also many safety precautions involved in using these units, and I think you have to take a course -- at least, I think you must take one here in order to use the unit and also work with a second person who knows all about using it. As you can see in the photo, the operator must wear rubber waders and rubber gauntlets to avoid being shocked. I don't know about the cost of the units, but I'm sure they can be found online. They require large batteries which must be charged before each outing. Also, the unit weighs quite a lot, so it is tiring to use. Those are the things I can tell you about it. As mentioned, I've seen very good results with seine nets. Are you hoping to capture large fish or smaller ones? The seines work quite well for smaller sized fish and minnows. The only problem with a seine is it isn't useful in shallow water where there are many rocks. However, you can also set up a net across a stream and then get a few people to help drive fish to the net. I will send this note to you by email as well and you can email me privately if you want more information. -- bev
