Question from David, a parent: 57 grams of feed how many fish can I feed at 2% of 1lb body weight or I suppose to feed 2% of body weight of food in grams fish weights 1 lb. I hope I said that write |
Hi Dave,
You need to make sure that you have similar units for your calculation and 1 lb is about 454 grams. To feed one fish with a mass of 454g, it would take 9.08g (0.02x454g) of fish food. So if you want to know how many fish you can feed:
(9.08g)x(number of fish)=57 g
Now solve for the number of fish.
Hope this helps,
Janice
