When I started curing my egg's with the anise oil it seemed like to hatchery fish were all over it and the nates not so much.After 10 plus years of using this anise cure it doesn't seem to matter if it's a brat or nate any more it works well for both.How ever I prefere to use the anise egg's more during brat season and sandshrimp more during nate season.Go figure.Good luck,
SZ


P.S. Never have heard of anise oil being in the fish food.
