From my pond, enough for one person (I don't know if Kate, my Springer Spaniel would like fish for dinner). I have no problem with one meal per week, and recently I had a bunch of friends over. We pulled out enough fish to feed 20 people.
I normally take out LMB because I have to stay on top of the population or it'd overgrow the food chain. For the 20 people, it was LMB, BG and some YP.
