Burbot!

  • We are currently upgrading MFK. thanks! -neo
There ya go; how's that? No "guess what's in the bag?" nonsense, just come right out and say it: burbot.

I'm a fan of native fish in the aquarium; my only previous experience with Burbot was with a couple that I hand-caught as 4-inch youngsters in the shallows of a crystal-clear northern Ontario lake and kept for a couple years indoors, before losing them to some backyard predator after moving them outside. I've thought about them many times since then, but they are not a fish I regularly encounter and nothing has come of it. But I never go fishing without emergency bring-'em-back-alive supplies in the truck, just in case...

...and I finally had a case! All of yesterday spent icefishing resulted in a couple nice eating-size Walleyes, a few other assorted fish...and, at day's end, an absolutely beautiful Burbot of roughly 12 inches length. When it came through the ice, I went into full fish-nerd mode, amusing my fishing partner as I dashed around filling a couple plastic pails with icy lake water and rushing the fish to the truck. I dashed off home, 30 minutes away, leaving my buddy sitting alone in the middle of a frozen lake in the dark, surrounded by all of his gear and most of mine.

I had a plastic tub of roughly 80-100gallons capacity sitting waiting, but of course it was empty; it needed to be filled with the coldest well water I could provide, and then further cooled with snow to bring it down to the 35F temperature of the water I brought back with the fish. I added about 20gallons of lakewater, and then floated the fish in its travel container, equipped with an airstone, while slowly mix-acclimating it for about an hour. It was clearly stressed and I was worried.

I have done a mid-winter collection like this several times, always with common fish that I am ashamed to admit were guinea pigs for testing my techniques. It's worked well, and catfish, rock bass, sunfish and a few assorted smaller species have acclimated without incident...but this time I wasn't experimenting or playing around; I was as serious as a heart attack. Fortunately, the Burbot had come from only 12 feet of water; the few I have caught in past years have all been deep-water fish which would have complicated this procedure probably beyond my willingness to attempt it. Additionally, the water parameters tested very close or identical to my well water in terms of pH (7.5) and hardness (300+ ppm). Aside from the stress of capture, hooking, handling and transport, the main issue that concerned me was temperature shock.

The water temperature rose gradually overnight; the tub is on the concrete floor in my basement, which is cool, so heating up was as gradual as possible, and I went out several times during the night in my PJ's to bring in a few shovelfuls of snow to moderate the temperature increase. By 9 this morning, the temp was approximately 40F, and will only come up another 10 degrees or so before levelling off. I plan on adding more snow today, and hope to hit 50F (that's as high as a container of water on the floor will go) sometime late tonight. The fish looks much better this morning, better colour and generally less visible signs of stress. So far, so good.

I chuckle when I think of a recent post here on MFK in which a member stated that he planned to "gradually" drop his tank temperature from 78F...to 77F! :)

My plan is to keep the fish in this container, with high aeration and the addition of a matured sponge filter, for at least a few more days. At that point he will be moved into a 70-gallon unheated tank on a stand which will sit at roughly 55F, and if all goes well, he will be installed in the 360, at that same temperature, by the end of March. Temperatures by the middle of summer will likely top out at 65F or a bit less.

Sorry, I took no pics yet; when I have stuff to do I rarely consider stopping to take snapshots. Nothing to see anyway; a fish in a dark tub of water in a darkened room doesn't display well, and I don't intend to turn on the lights unnecessarily for now. When he's behind glass in a tank, I will get some pics; or, worse coming to worst, I will take a shot of the cadaver.

In case it isn't obvious by now: I am as seriously invested in keeping this fish alive as any I have ever owned...ever. I will definitely follow up on this post, good or bad; fingers are crossed.

And, yes, before anyone asks...after I did what was needed at home, I raced back to the lake to help my buddy pack up his gear. He had actually hooked another Burbot after I left, roughly twice the size of the first, but lost it right at the surface. He had caught one before in his entire life...and then hooked two on the same evening. He was excited...perhaps even excited...but I was, and am, EXCITED!!! :)

What’s the legality with keeping native fish in canada? It’s something I’d like to do but haven’t really researched. It seems like it would be complicated with different fishing seasons and what not.
 
Well, you know our fish'n'game laws; they vary widely from province to province, location to location, and quite often from one fish cop to the next. I know that in my province, gars and bowfin (both of which I would have loved to keep) are strictly forbidden. Burbot are not on any ban list, and checking with the local Ministry office resulted in a clear okay; maybe I will check other species in the future but I really have no reason to do so.

A Conservation Officer in Ontario told me once that I could bring home game fish like bass, walleye, etc. legally in season...but could not keep them once the season had closed. A Ministry office then said that was completely erroneous. Who to believe? It's not good enough for it to be legal if some enforcement people treat it otherwise. Do your homework thoroughly...locally.
 
Lota lota fun!
Here in Minnesota, I catch fingerlings in the spring fed streams of the St.Croix May till July. 54°F water comes out of limestone cliffs and travels into the river. Stream beds are broken slabs of stone usually short runs (1000 feet) and usually less than two feet deep and several feet wide.

The young fish "hide" at the margins under small flat rocks in remarkably shallow water. It would be normal to find a 6" long fish under a thin slab similar in diameter to the length of the fish laying flatwise in water under 3" deep with the rock partway above the surface. Why they do this is a mystery. There's plenty of food and hides deeper in the streem. It would seem to make them very susceptible to predators. At least during the daytime they are the largest fish in the stream. I've found they behave oddly in the aquarium as well. But my experiences are limited.

I look forward to reading about your new pet.
 
Great info, thanks! Those conditions you describe are very similar to the habitat in which I caught my first pair of these guys at around 4 inches or so in length. I knew very little about them at the time, had only seen one large one ever before, and was astonished to catch one of these supposedly deep-water denizens in water only a foot or so deep, while searching for crayfish. Catching the second one a few minutes later completely floored me. :)

Lots of conflicting information about them as aquarium fish. I don't keep fish based upon how challenging they are considered to be; an easy keeper can be just as appealing to me as a delicate species. But I probably an taking extra precautions with this one due to some of the warnings I have received about their fragility, so a little bit of fearful respect may be working in the fish's best interests.

It's temporary 70gallon interim home is now ready; hopefully some pics of it shortly.

One thats always been on my “list”… congrats on getting it home safe and great story behind it already… I too keep an “emergency” fish kit in my truck in case i come across any wild color morphs or albinos while im out… one day haha…
 
Where's the pic of this new guy John?

He will moving into the 70 within another day or so; pics after that.

I posted an hour before your post ^ that pics would be "shortly"...I think it's adorable that you believe that means anything under a week...:)
 
Temperature in both tanks...temporary tub and interim 70gallon...is stable at 50F; the 70 is on a stand, whereas the tub sits directly on the floor, so I expect the tub to go up another couple degrees eventually. Water parameters are still excellent in both containers, so I did a roughly 75% change in the tub last night, using water that had been sitting in other storage containers next to it for this purpose. Then, this morning, I gingerly maneuvered the fish into a bucket and then transferred it to the 70.

I'm now having my morning coffee in the fishroom, Duke is snoozing on his cushion nearby, and I am awaiting the sounds of stumbling, shuffling and muttering from upstairs that signal my wife's awakening; she sleeps in later than I do. The fish has been exploring his new home inquisitively, at all levels. His breathing may be slightly faster than normal, but it's hard to tell; observation of details has been difficult in the dark, covered tub in which he spent the last couple days. Lights are still out, but it's still much brighter than he has been exposed to since getting here. A large mature sponge filter and an extra airstone ensure aeration. I am not using any other means of circulation, as all my pumps are submersible and I don't want to add any heat to the tank. No plants for now, as I don't know when or how much light I will be providing. Bare tile bottom, a couple big chunks of driftwood. The tank is covered to minimize evaporation and unauthorized excursions; I have never heard of these fish being jumpers or escape artists, but they certainly have that "look" about them.

After an explosive breeding of Umbra mudminnows in my pond last summer, I have a tankful of them now, so I added a carefully count of 10; I'll be counting them a lot to see if the number changes...

Yes, yes, I know...pics, pics, pics...patience. Soon. It now appears as though the pics will indeed be of a live fish, rather than a corpse. :)

Still 10 mudminnows present and accounted for. The burbot is active and exploring much of the time, but also spends time lurking under the driftwood. It seems quite unconcerned about the lights being on.

The colour has pretty much changed to match the larger ones I have caught; a mottled brown-green, with some patterning and borders on the fins. A whitish spot at the front of the dorsal fin, a fair bit of white on the splayed and tentacled pelvic fins, and of course the unique white goatee.

A couple of quick snapshots; hopefully some more when I get better lighting set up and both I am the fish relax a bit more so that I can clean the front glass.
