I had a fish kill a couple weeks ago and with the low water I think it is time to start over. However, I don't want to use rotone to kill off fish. I want to seine and pull out what I don't want.

I have some questions about seining. I have never ran a seine before and I think I am looking at this way wrong. I know you can never get 100% of the fish in the pond by seining.

Right now my pond is about 130' x 370', max depth around 3', all due to this drought we're in. Am I crazy thinking I will need a 130' seine net to do what I want? Or should I get a smaller one and just run it several times? What's the best method here? Thanks
