A combination of genetics and environmental factors (principally lack of food) will mean that some trout will go to sea to feed before returning to spawn. This is called an ’anadromous’ lifestyle. Trout also migrate within the river and from lake to river.
What is the difference between trout and sea trout?
In terms of their shape, sea-run brown trout are identical to brown trout, but a sea trout has a much more silvery appearance. However, the color of an adult sea trout may darken as it journeys through freshwater, at which point it can be challenging to distinguish a sea trout from a brown trout.
What is an ocean trout?
‘Ocean Trout’ is a term used by Tasmanian growers using open-pen sea cages to raise Trout.

Do brown trout go to sea?
This species has two possible life-cycle patterns. While brown trout are purely freshwater-resident, ‘sea trout’ migrate to the sea to feed and mature. Some Scottish rivers are home only to brown trout populations.
Do trout migrate to sea?
By measuring strontium in the lake trout otoliths, the scientists found that adult fish first migrated to the ocean at different ages (16-45 years) and there was a wide range in how often they used marine habitat throughout their lifetimes. Some of the fish only migrated to the ocean once, others up to nine times.
What is a sea run brown trout?
Sea-run brown trout are popular game fish that grow very large at sea before returning to streams and attracting many anglers in their pursuit. Sea-run trout streams are designated waters believed to be able to support anadromous brown trout. These areas are stocked with fingerling and yearling brown trout.
Is there any trout in the ocean?
Oncorhynchus mykiss
Also referred to as Steelhead Trout or Sea Trout, we most commonly familiar with these fish in the U.S. as the ocean-going “steelhead” trout ( or even as the “salmon trout”). But they are in fact in the same species as the freshwater “Rainbow” trout found in our American lakes and rivers.
Are there worms in trout?
Spaghetti worms are common parasites of saltwater fish in the drum family, which include speckled and white trout, black drum, redfish, and croakers. While they look alike to most fishermen, several different worms use these fish as hosts. Most common in sea trout is Poecilancistrium caryophyllum.
Where do sea trout come from?
Some trout migrate to the sea and may live there for years (being classed as ‘sea trout’). Others, stay in freshwater their whole lives and are known as brown trout. Trout found in the sea are almost certain to be female. After a while they will travel up rivers to return to the freshwater environment and spawn.
What eats a brown trout?
Brown trout are preyed upon by piscivorous birds, mammals and other fish. Common mammalian predators are humans, river otters (Lutra sp.), and mink (Neovison sp. or Mustela).
How deep do brown trout live?
How deep do brown trout live. Brown trout (Salmo trutta) prefer to stick close to the surface, although some complete dives down to 90ft (28m). In extreme water conditions, they might go deeper following the thermocline.
What is the world record brown trout?
44 pounds, 5 ounces
In October 2020, Seumas Petrie landed the new IGFA all-tackle world record brown trout weighing 44 pounds, 5 ounces.
What are the two types of brown trout?
Although there are currently no recognized subspecies of brown trout, there are three basic morphs (distinct behavioral populations within a species): those that in habit freshwater rivers (Salmo trutta morpha fario), lake populations (Salmo trutta morpha lacustrine), and anadromous forms (Salmo trutta morpha trutta).
How can you identify a sea trout?
Salmon parr (I) can normally be distinguished from young brown/sea trout (II) by the more streamlined shape, deeply forked tail, longer pectoral fin, lack of orange on the adipose fin, smaller mouth, sharper snout, only 1-4 spots on gill cover (often one large spot), well-defined parr marks.
What’s the best bait for brown trout?
The best baits are live nightcrawlers, minnows, and spawn on a #4 hook or smaller. Get some weight above your hook, such as a split shot or an egg sinker (depending on the conditions), to keep your bait in the strike zone. Let it move through the water like an easy target.
Are brown trout bottom feeders?
Trout are not bottom feeders like carp or catfish. But, they do feed predominantly near or just off the bottom. Trout prefer to wait and cruise in the bottom 2-3 feet of water to intercept any food that drifts by.

A wild brown exhibits more vivid colorations, yellowish belly, bright red spots, a red-tipped adipose fin, and sometimes even red-lined tail fins. The trout in the lead photo at the top of this post displays all of these markings of a wild brown, and it most certainly is a wild brown.
What time of year is sea trout?
Generally, though, sea trout will begin to run in numbers in early summer, perhaps in May, and numbers will build up during June and July and into August. Successful tactics for sea trout can vary somewhat from river to river and region to region but, in general, the hours of darkness are the most productive.
