Sea fish?

[-MARWOLAETH-]

Can I feed Atlantic mackerel (Scomber scombrus) to my marcianus?

The areas I can catch and buy them from has little pollution and heavy metals but I'm still unsure if they'd be suitable.

Mackerel are thiaminase free, right?

The risk of heavy metals tends to be with fish that are longer lived and therefore have longer to accumulate in the tissue. Mackerel are smaller with short lifespan aren't they?

Mackerel (Scomber scombrus) is on the list of thiaminase free fish.

"Mackerel are thiaminase free, right?"

The Atlantic are safe but its the Chub/Pacific mackerel (Scromber japonicus)that contains Thiaminase.

That's good to know. I guess I should give them a go and see if they're to her liking

I've not fed mackerel, but I have fed hake which is also thiaminase free. I'm not sure why I decided not to continue with the hake, probably because my guys didn't take it as reliably as salmon and trout and smelt.
If you catch mackerel I'd give it a go - safe, free food isn't to be sniffed at.
