Greetings from the south shore of Superior - Michigan.
I am looking to learn about Coasters.
The way I understand it, the latest theory is that simple stream population totals of Brookies creates Coasters. So if fishing for Brookies is more limited, more Brookies will exist in a stream and then more will opt out to the big Lake.
Has this become true anywhere in Ontario besides the famous fishery in Nipigon? (And how has that been lately?) I believe Minnesota has had success with an improving Coaster fishery via tight limits on Brook Trout.
Michigan is experimenting with the same idea on a dozen streams. I haven't been able to fish those.
But I know some streams where I am at ... well, tales are told. I know the streams hold Brookies, but are hardly fished.
I want to catch a Coaster, but it's a mysterious topic.
When do they start "Coasting" ? I have heard July. But that creates many other questions - what time-frame are they in-shore vs. in the river vs. back out to deeper waters?
I want to fish for them from the beach - is this worth pursuing? My only idea is to throw a crawler out on a rig normally used with spawn for Steelhead. And, I was thinking to try casting a little bit too. I already catch Cohos in small creek lagoons on Superior, simple enough. I would of course try the lagoon first but it wouldn't take long to discover a Coaster willing to strike.
I caught four nice Brookies just a couple dozen yards up from a lagoon the last couple days, all 10"+. I kept one that started to bleed but otherwise have no plans to do so. The one I kept had a surprise - small spawn inside about the size I would have usually seen in stream Brookies at the end of the open season for them in late September.
I wonder a few other things - can a Coaster come out of the same stream as Steelhead do? Does the Nipigon River have a Steelhead run?
And how long do Coasters live? Do they spawn more than once? I know Brookies are technically neither a Trout nor a Salmon, which differ on that question.
