Lake Perch Fillets--5 pound package of individually frozen butterfly fillets. These vary in size but are usually very small when they taste the best. Yellow Perch or Lake Perch are a cousin of the larger walleye, but taste very close. Like our other smaller fish we do the dirty work and clean the fish so it is ready for your pan. Please note that this is real lake perch (Perca flavescens) from freshwater inland lakes. I have spoken with many customers who have ordered ocean perch or Lake Victoria perch from other sites online that are not the same fish. As with our other products these are Individually Quality Frozen so you can grab just one or two fillets for dinner without defrosting the rest.
