Native ? Do you mean regular BG ?

I would not put HBG in with BG, CNBG and RES. If you want them then wait until the initial stockers are 2 years old , if at all. It has the potential to cause a genetic trap. Be sure you understand Crappie well before you add them - lots here on the Forum about the potential to cause problems in small waters (under 40 acres). With those numbers of BG be sure to wait for them to spawn before you add LMB.
