Suspend your bait about three to five feet from the bobber over a dropoff. When fishing landlocked salmon in a lake, you can use the same bobber you would use for the trout. Spinners, spoons, and flies are effective lures. You can also fish trout by using some split shot to sink the line and allowing the bait to float a foot or two off the bottom. In lakes, you can catch trout using a worm suspended under a bobber. Some behavioral differences will affect how you retrieve and where you cast. Trout and salmon each much the same food, so the bait and lures you choose can bring in either fish. Trout don’t have to go into saltwater at all and can live their entire lives in either freshwater or saltwater. Once they spawn, trout hang around longer before they transit to the ocean, so that they can get bigger before facing ocean predators. Trout can spawn many times and don’t necessarily return to the saltwater environment afterward. That means they only spawn once and usually don’t make it back to saltwater. After this change, they’re known as steelhead. When they prepare to go into the ocean, they must go through a biological shift that enables them to handle saltwater conditions. Rainbow trout spend the first part of their lives in freshwater. They come in from the ocean and head upstream into freshwater rivers and streams. Salmon famously return to their spawning grounds every year. Although salmon are often found in saltwater and trout in freshwater, this isn’t always the case, especially when spawning. The biggest difference between trout and salmon when it comes to fishing is where they live. Knowing the difference is important for three main reasons: it helps you identify the fish in the area and what lures they’ll go for, some of these fish are protected by law and you don’t want to get caught with the wrong ones, and knowing which is which is useful for population counts and restocking plans. You can also tell by differences in the mouth. Trout have a dozen or fewer rays in this fin. Another good bit of anatomy to look at is the anal fin. Trout have thicker bodies, a more rounded head, and more scales from their adipose fin to their lateral line. Salmon are more streamlined, have a concave tail shape, and their upper jaw doesn’t go past the eye. Salmon have more patterning above the lateral line. The first difference is their color patterns. They don’t work in every single instance, but for our purposes, they’re good enough. However, several good key differences work as an overall sorting strategy. Some of these fish look so similar that it’s hard to tell which is which without taking tissue samples to a lab. The third family (called Salvelinus) consists of the brook, dolly varden, bull, and lake trout. The Atlantic salmon and the brown trout have their own family (called Salmo). Let’s break down the salmonid family tree.Ĭutthroat trout, rainbow trout, and all of the salmon except for the Atlantic salmon are in the Pacific trouts and salmons family (called Oncorhynchus). They’re all in the same family, some are just more closely related than others. salmon question isn’t a one-to-one comparison. You probably already know that there are several kinds of trout and several kinds of salmon. Find out what the scientific difference is, what the difference is when fishing them, and how they’re different on the plate. So, how do you tell the difference between a trout and a salmon and how do you sort out who’s who? Beyond that, why does it matter? The answers to those questions and more are in the following article. They’re both in the same fish family – the salmonids – but some fish called “trout” aren’t technically trout and some fish called salmon aren’t technically salmon. The other is an Atlantic salmon (and an ichthyologist is a fish scientist). The first one is the scientific name for rainbow trout. Pop quiz: Do you know what an Oncorhynchus mykiss is? How about a Salmo salar? No? Well, unless you’re an ichthyologist, don’t feel bad.
