Crayfish trapping is easier than you think. Depends on what kind of volume you're looking for, but typically, you have a funnel style trap with some sort of meat inside.
You can make simple wire traps with a funnel neck for them to crawl in to or my son just took some old two liter bottles and cut part of the top off. Cut the lid portion off so the hole is big enough for them to crawl through. Reverse this portion and secure to bottom portion. Add bait such as meat, fish bones from your days catch or even dog food pieces. Good luck, they are worth it.
it is legal but you need to buy a nys fishing license--good luck eating them ---not much for meat--but maybe good for flavor in like a chowder or some seafood type dish-maybe
When's the best time of year to trap them?
