Caught snake pricklebacks in the salt as well, almost always in deeper water off piers. Don't like handling them at all due to the numerous dorsal spines. I wonder how they taste as I always throw them back. Went for stocked rainbows instead at nearby Lafarge Lake and got myself one for dinner..lol Will like to try a nearby slough again for cutts and bulls this weekend so flounders will have to wait till next week.
One thing widely used a lot by UK beach match anglers while flounder fishing is to incorporate a sequin or two (yes, the kind you see in ladies dressmaking stores) threaded onto the hook trace..... these sequins are set between brightly coloured beads, they add that extra sparkle and seem to work quite well when placed near the hook bait to attract all manner of bottom fish, like flatties, doggies, etc.
