Living in the far North, I usually take Vitamin D, the sunshine vitamin, during the winter months (1000 IU/day). This year I wanted to see if a local diet alone would keep my Vitamin D levels stable. Not unexpectedly, my levels dropped below normal as the days became shorter.
But, thanks to local Dawsonite and ice fisher, Jim Leary, I was introduced to burbot and it saved the day!
Burbot is an amazing fish. It is a freshwater, carnivorous, bottom feeder that thrives at the coldest times of the year under the ice of the Yukon River. In fact, it has chosen January as its favourite spawning month. Burbot live to be decades old. They have no scales and some folks find them a bit ugly and eel like. I think they have beautiful eyes. A survivor if ever I saw one. Which leaves me with some ambiguity about catching them. But their flesh is a thick and delicious white fish and their livers are especially nutritious.
Burbot liver is huge – six times larger than the livers of other freshwater fish of the same size, and comprising about 10% of their body weight! And their liver is packed with Vitamin D and Vitamin A, in fact 4 times the potency of the Vitamin D and A found in cod liver.
Turns out that a mere 10 grams of burbot liver per day would supply me with the equivalent of 1000 IU of Vitamin D. Chopped into chunks and sautéed in butter, burbot liver tastes similar to scallops. So consuming 150 grams of burbot liver every couple of weeks was no hardship on the palate.
And it worked! Thanks to the burbot, my Vitamin D levels returned to normal.
Fish tend to accumulate toxins from our water systems, especially carnivorous bottom feeding fish. I will share my findings on mercury levels in burbot and some other Yukon fish in the next blog.
