Google plastic net/fence mesh material 1/8" or 1/4". Lots of options - I usually just buy my rolls at the retail box store 3' x 25' x 1/4" etc. as it's a lot cheaper and works fine vs. mesh material offered on aquaculture websites. If you need a specialty size you'll have to search a bit online but it's around.
