How much does each "meal" weigh and do you feed once or twice a day? Do you feed them anything else besides the fish? I'm very interested in this too. Thank you.
My two eat twice a day and they get about 400grams a meal (454 grams is a pound). So, about 2 pounds a day of raw meat.
A typical mackerel is anywhere from about 350 grams to about 500 grams. If you wanted, you could portion exactly, but I usually just give them the whole fish. If they get a little too fat, I reduce them. I don't fuss too much with the weight.
The mackerel is a part of my guys diet, but they also get organs, chicken, turkey, etc. quite a bit of fish though. I buy the fish for $2.20/lb and buy it in 15kg cases. I take it out in the morning from the freezer, let it thaw in the fridge and hand them a fish at dinner time. My two will NOT eat it if it's conpletely thawed. They like it just thawed enough to bite off frozen chunks. It's a consistency thing.
At dinner I take out their morning meal from the freezer and into the fridge it goes for breakfast!
I feed mackerel simply because I can get big cases of it for a relatively decent price. Out of all the raw meat I feed, the fish is the most expensive.
In terms of fresh fish from a lake, Peter may know better than me, but I would only feed it after deep freezing for three weeks or so and I'd want to do some research on the specific fish and region to ensure the fish was safe to eat. I wouldn't be at all worried about bone content.
They do not get anything else with their meal except their normal add-ons like kelp, salmon oil, etc
