'The Shocking Science Behind Fish Surveys'

Brings back memories in the fisheries class I had back in college. We were shocking a stream one day and the professor stuck the probes up under a bank where you wouldn't think much would be and out pops up a 10 lb. steelhead. Every so often we did have a fish or two die from it so it isn't always foolproof.

Same can be said for tackle fishing.

Good share JB! Is there a "safer" time of year to do this? It seems most videos I've seen look to be in the spring.

Also, would this be a good option for things like Asian carp? (Can we even call them that anymore?)

I think spring probably is the best time of year to do it. Aquatic vegetation hasn’t really exploded yet, and the water is cooler so dissolved oxygen is usually higher. During the summer when the water temp is high I would think it would create too much stress on the fish. Regarding Asian Carp, this is definitely one of the methods used for surveying. Electro-fishing is used extensively for searching for all types of carp. There’s actually a Great Lakes region task force of sorts, made up of multiple state and federal agencies, that spends a large portion of time on the hunt for all kinds of invasive fish, and electro-fishing is the main surveying tool used from what I’ve seen.

Does it work on snakeheads? Those two seem to be the big hype fish these days. Makes me wonder why it's such a big deal if we could remove them in this way. Cost effectiveness?

I’ve seen them doing at various impoundments around NE Ohio. Always seemed interesting and have wanted too wander by too check it out. But, and theres always a but, I like my electronics too much too do it 😂

I'm thinking if they supplied the boat and equipment, it would be easy to find volunteers to man the nets to do the work. I know I would give up some hours to my local fisheries.
I think that there are so many variables that it would be cost-prohibitive to turn the general public loose with electro-fishing equipment. Water temp, turbidity, current, depth, AC current vs DC current, equipment failure and maintenance, etc.
