The populations of brook trout in the sampled lakes ranged from an They prefer clear waters of high purity and a narrow pH range and are sensitive to poor oxygenation, pollution, and changes in pH caused by environmental effects such as acid rain. October 2018 [1] [3] A potamodromous population in Lake Superior, as well as an anadromous population in Maine, is known as coaster trout or, simply, as coasters. From the east coast their native range extends westward to eastern Manitoba and the Great Lakes (Willers, 1991). July 2016 For example, in spring, growth increased with temperature at a faster rate with high flow rates than with low flow rates.[14]. As far as the United States goes, brook trout are the most widely distributed native salmonid. You can find this species as far north as Canada, and as far south as the southern United States. The brook trout was eventually introduced into suitable habitats throughout the western U.S. during the late 19th and early 20th centuries at the behest of the American Acclimatization Society and by private, state, and federal fisheries authorities. In Lake Superior, large brook trout will migrate into streams in the fall to spawn. The landlocked Atlantic salmon fishery alone is worth the travel and lodge experience. [33] Because of its dependence on pure water and a variety of aquatic and insect life forms, the brook trout is also used for scientific experimentation in assessing the effects of pollution and contaminated waters. The female then buries the eggs in a small gravel mound; they hatch in 95 to 100 days. Warm summer temperatures and low flow rates are stressful on brook trout populations—especially larger fish. Growth rates are dependent on season, age, water and ambient air temperatures, and flow rates. [citation needed], In addition to chemical pollution and algae growth caused by runoff containing chemicals and fertilizers, air pollution has also been a significant factor in the disappearance of brook trout from their native habitats. A majority of spawnings involve peripheral males which directly influences the number of eggs that survive into adulthood. Brook trout are native to a wide area of Eastern North America, but are increasingly confined to higher elevations southward in the Appalachian Mountains to northern Georgia and northwest South Carolina, Canada from the Hudson Bay basin east, the Great Lakes–Saint Lawrence system, the Canadian maritime provinces, and the upper Mississippi River drainage as far west as eastern Iowa. The typical pH range of brook trout waters is 5.0 to 7.5, with pH extremes of 3.5 to 9.8 possible. [24] The eggs are slightly denser than water. [41][42][43] In the northern Rocky Mountains, non-native brook trout are considered a significant contributor to the decline or extirpation of native cutthroat trout (Oncorhynchus clarki) in headwater streams. This type of life history strategy is called adfluvial. Diet: They're opportunistic feeders, happy to eat aquatic insects or smaller fish. Though commonly called a trout, the brook trout is thus actually one of the chars, which in North America also include the lake trout, bull trout, Dolly Varden It was the only time during this study that a trout entered a tributary stream. The maximum reported weight for a brook trout is 8 kg (17 lbs. Brook trout are some of my favorite fish to target on the fly. The belly and lower fins are reddish in color, the latter with white leading edges. February 2017 The species was later moved to the char genus Salvelinus. Range: Native to the Easter United States 3. In spring, they go deeper to find cooler waters at about 10-20 feet. The aurora trout, S. f. timagamiensis, is a subspecies native to two lakes in the Temagami District of Ontario, Canada. [18] Although not all introductions were successful, a great many established wild, self-sustaining populations of brook trout in non-native waters. Finally, a smaller generalist form that evolved in the small lakes, ponds, rivers, and streams throughout most of the original native range. Brook trout movement ranged between 0.5- mile and 11.6 miles with the greatest movement occurring in Tunkhannock Creek. [28], Today, many anglers practice catch-and-release tactics to preserve remaining populations, and organizations such as Trout Unlimited have been in the forefront of efforts to institute air and water quality standards sufficient to protect the brook trout. In small streams brook trout are often 5- to 7-inches long but can reach 25 inches or more in large rivers or lakes. The telemetry tagging was just one part of the data that I am collecting this summer. Status: Not listed under the Endangered Species ActThe brook trout is a fish native to the eastern United States, and is often referred to as speckled trout, spotted trout, brookie, and squaretail. Good luck Shannon! [citation needed], The female constructs a depression in a location in the stream bed, sometimes referred to as a "redd", where groundwater percolates upward through the gravel. One of the tributaries to that reservoir is stocked with splake, about 5 or 6 miles upstream from the reservoir. R. Rockitout New member. We stayed at the Riverkeep Lodge on the Atikonak River. Trains would transport anglers from New York and Boston to the mountains of Vermont and Maine just for the opportunity to lay into a big squaret… January 2018 I can tell you that trout in general travel a long ways, but here's some real examples. The maximum recorded length is 86 cm (34 in) and maximum weight 6.6 kg (15 lb). They do need gravel, and cold flowing water, and will travel to seek it out. In general, the larger the number of peripheral males present, the more likely the eggs will be cannibalized. Genetics The brook trout was first scientifically described as Salmo fontinalis by the naturalist Samuel Latham Mitchill in 1814. [13], "Synonyms of Salvelinus fontinalis (Mitchill, 1814)", "Recovery Strategy for the Aurora trout (, "Sparctic Char: Strange Nighttime Saltwater Spawners from Europe! This stream has been impacted by cranberry bog farms since the mid 1800’s. alpinus). The brook trout is a brilliantly colored fish that lives in clear, cold freshwater streams and rivers in undeveloped areas throughout the Chesapeake Bay watershed. Their range extends as far south as the Appalachian Mountains in North Carolina and as far west as Minnesota. [32], Brook trout are also commercially raised in large numbers for food production, being sold for human consumption in both fresh and smoked forms. March 2018 [27] As brook trout populations declined in the mid-19th century near urban areas, anglers flocked to the Adirondacks in upstate New York and the Rangeley lakes region in Maine to pursue brook trout. You can get a good estimate of the depth. Tagging a fish is a true surgery, complete with sutures to close the incision. For Brook Trout, try to stay in not more than 20 to 35 feet of water and close to shore. S. f. agassizii (Garman, 1885)† [13], The brook trout has a dark green to brown color, with a distinctive marbled pattern (called vermiculation) of lighter shades across the flanks and back and extending at least to the dorsal fin, and often to the tail. [citation needed]. January 2017 A sought-after game fish because it often lives in pristine waters and readily attacks flies of all kinds, it was the first destination fish in the Americas. There are businesses that hold a "U-fish license", where the public can come fish at their lake or pond and buy the fish that they catch. Unlike other anadromous fish, salters usually do not venture far from their natal streams and they typically only remain in saltwater for up to several months before returning to freshwater. 10 oz.). In Maine they are sometimes called squaretail, especially by older anglers. On the other hand, three ecological forms are distinguished. May 2017 September 2016 [20], A potamodromous population of brook trout native to Lake Superior, which migrate into tributary rivers to spawn, are called "coasters". There is little recognized systematic substructure in the brook trout, but two subspecies have been proposed. The maximum length of fish sampled was 14.9 inches. However, within two weeks of returning to fresh water, they assume typical brook trout color and markings. "Stream prettiness" wasn't a factor I considered when picking study sites, but it worked out in my favor. How to Clean Brook Trout Habitat: Brook trout are an introduced species, first stocked in the early 1900s. They are often found in clean, cool mountain streams, including the Chesapeake Bay watershed, and are most active around dawn and dusk. Have the right tools! Similar to other trout, with violent motion of the body and tail, the female digs a shallow nest depression in the bottom gravel (a "redd") where there is good water flow to bring oxygen to the eggs. Although uncommon in nature, they are artificially propagated in substantial numbers for stocking into brook trout or lake trout habitats. Miscellaneous A distinctive sprinkling of red dots, surrounded by blue halos, occurs along the flanks. It may also be helpful to ask yourself where a predator might have the hardest time seeing and catching a brook trout – that is where the bigger ones will be. Sporting writers such as Genio Scott Fishing in American Waters (1869), Thaddeus Norris American Anglers Book (1864), Robert Barnwell Roosevelt Game Fish of North America (1864) and Charles Hallock The Fishing Tourist (1873) produced guides to the best-known brook trout waters in America. [38] Today, in many parts of the range, efforts are underway to restore brook trout to those waters that once held native populations, stocking other trout species only in habitats that can no longer be recovered sufficiently to sustain brook trout populations. Literature [10] Although they are fertile, back-crossing in nature is behaviorally problematic and very little natural reproduction occurs. Not Trout [31] This trout weighed about 15.98 lb (7.25 kg) based on the accepted formula for calculating weight by measurements, and it currently stands as the record brook trout for Manitoba. One Tunkhannock brookie moved about 7.5 miles downstream before ascending another creek. The fish are typically fed a pelleted food consisting of 40–50% protein and 15% fat. If you come across a spot and catch a trout, odds are there are more of them there. August 2017 As early as the late 19th century, native brook trout in North America became extirpated from many watercourses as land development, forest clear-cutting, and industrialization took hold. Such crosses are almost always reproductively sterile. [7] A large lake form evolved in the larger lakes in the northern reaches of its range and are generally piscivorous as adults. This post was also only about how far you have to travel to reach your closest wild brook inhabited stream. As Sayfu says, behaviors vary across streams and trout popns. Brook trout are members of the char subgroup of the salmon family (Salmonidae) which also includes the Arctic char, bull trout, Dolly Varden and lake trout. [citation needed], Organizations such as Trout Unlimited and Trout Unlimited Canada[23] are partnering with other organizations such as the Southern Appalachian Brook Trout Foundation,[39] the Eastern Brook Trout Joint Venture,[40] and state, provincial, and federal agencies to undertake projects that restore native brook trout habitat and populations. Brook trout are often referred to as eastern brook trout, and occasionally, brook charr, common trout, mud trout, salmon-trout, speckled trout and specs. If you fly fish long enough you will quickly realize that […] 1. [4] The silver trout, (Salvelinus agassizii or S. f. agassizii), is an extinct trout species or subspecies last seen in Dublin Pond, New Hampshire, in 1930. These brook trout, known as “salters”, have migratory tendencies. Labrador is so much more than brook trout. That being said, the more members that state they live within minutes of these beautiful waters only makes my jealousy raise higher. The specific epithet "fontinalis" comes from the Latin for "of a spring or fountain", in reference to the clear, cold streams and ponds in its native habitat. Brook trout are also raised commercially and sold to angling organisations or groups to stock their own lakes or ponds. They hunt by lying in wait for food to float their way. “Brookies” are considered an indicator species, because they help indicate the health or overall quality of the waters they inhabit. In the Lamar River drainage, a mandatory kill regulation for any brook trout caught is in effect. Though commonly called a trout, the brook trout is thus actually one of the chars, which in North America also include the lake trout, bull trout, Dolly Varden, and the Arctic char. [citation needed], Typical lengths of the brook trout vary from 25 to 65 cm (9.8 to 25.6 in), and weights from 0.3 to 3 kg (0.66 to 6.61 lb). Features: Brook trout are easily identified by the worm-like pale yellow markings on their backs and red dots with blue halos and white borders on their lower fins. Brook trout populations, if already stressed by overharvesting or by temperature, are very susceptible to damage by the introduction of exogenous species. That said, upstream migration is needed to spawn. When it comes to spawning runs, a 25-pound Chinook salmon in the Pacific Ocean has nothing over a 10-inch native brook trout in the Savage River. A smaller cousin of salmon, they live in cool, fast-running rivers and streams across most of North America. Catching colourful, wild brook trout (called “specks” in Northern Ontario) on a fly rod is a major incentive for fly fishers to visit Algoma Country. Although they might be on the smaller side, they are some of the most spectacular looking fish, and are not afraid to hit a dry fly! The species was later moved to the char genus Salvelinus. Tiger trout occur very rarely naturally, but are sometimes artificially propagated. Telemetry. Revenues derived from the sale of fishing licenses have been used to restore many sections of creeks and streams to brook trout habitat. Appearance Brook trout can grow up to 12 inches in length, but most are no more than 9 to 10 inches in length. Personality Brook trout are found as far south as Georgia in the Appalachian mountain range and extend north all the way to Hudson Bay.
