A year or two ago during the summer I caught a couple good gizzard shad with my cast net. I usually caught one per trip and caught 2 to 3 total. They were about 8 inches in length. Since then I have not caught another one in the same stream. It is not near any lake so they live in the river always but I have not caught one in a while. Could it have been a die-off? Where do you think I should find them in the stream? It is between 30 and 65 feet wide, just by estimation. It averages 3.5 feet deep but can reach up to 8 in deep sections. Where could I find more shad?
