Jaws I HIGHLY recommend being careful feeding those from the bait section. As stated above they are preserved in salts/oils/possibly synthetic preservatives in order to keep them in the bag like that outside of a freezer for extended periods of time generally. That may not be the case but I would definitely check into it before feeding too many.
Being an avid fisherman I see a lot of these baits used and almost every baitfish I've seen in a bag meant for angling has been preserved in salt brine or oil. My walmart carries green shiners on the rack in a bag...unfrozen lol so you know whatever they are doused in kills everything.
Man its not worth the risk. I'll just get the silversides meant for aquarium use.
Can i use these as bait in freshwater fishing ? Like trout and stuff. Bunch of lakes amd fishing holes near me. Son loves fishing i could care less hahah.
Where we used to live there was a small lake we'd go to and use pizza dough as bait and catch catfish. Where we live now theres "real" fishing lol and i have ni clue what im doing
