Rainbow Trout – Nutritional Value, Health Benefits, Recipes

The rainbow trout (Oncorhynchus mykiss) is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called “steelhead trout”) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.

Rainbow trout Facts

Rainbow trout is a member of salmon family. There are 15 subspecies of rainbow trout that are native to western parts of North America. Rainbow trout can be found on all continents except on the Antarctica today. These fish inhabit cold streams and rivers, while some subspecies spend part of their life in the ocean. They live on a gravelly bottom with enough vegetation that provides shelter. Rainbow trout are popular game fish. They are also important food source for humans. Because of that, rainbow trout are often cultivated in aquacultures (commercial farms) throughout the world. Despite increased demand for rainbow trout, their number is still high and stable in the wild. These animals are not on the list of endangered species.

Rainbow trout, which belongs to the Salmo family of fish, is closely related to salmon and Arctic char – two other fish rich in omega-3 fatty acids. It is native to cold-water tributaries of the Pacific Ocean in Asia and North America. Rainbow is the most widely known trout in the world and is highly sought after by anglers because of their strong fighting abilities. In Alaska, there are two commonly recognized forms of the rainbow trout and these sub-groupings or “forms” are based primarily on where they spend their time feeding and maturing. The most common rainbow trout in Alaska is the stream-resident form that lives its life entirely in freshwater with maybe short periods of time spent in estuarine or near-shore marine waters. The second form is commonly known as steelhead and these rainbow trout leave freshwater as juveniles and migrate long distances in the ocean where they grow to maturity before migrating back to their original home waters.

Appearance

The rainbow trout is a large, torpedo-shaped fish that usually reaches a weight of 8 pounds and a length of 20 to 30 inches in the wild. It is speckled with black spots on its bluish-green back, with a silver belly and a pink stripe on the sides of its body. Though, the rainbow trout’s coloration often varies depending on age and habitat. In addition to their black speckles, young fish have 8 to 13 dark vertical spots on their sides, called parr marks, which fade as they grow older. Rainbow trout living in freshwater habitats are often lighter in color than their counterparts in saltier waters. Some rainbow trout spend part of their life in the ocean. They are called anadromous or steelhead trout. Their body is almost entirely silver.

History

Rainbow trout is native to North American rivers draining into the Pacific Ocean; trout are now farmed across the United States for food and for sport.  North Carolina is the second-largest producer of rainbow trout after Idaho.  They are grown in earthen or concrete, rectangular raceways supplied with clean, flowing water.  Without a good source of water, trout farming is impossible.

Trout Types and Species

Different types of Rainbow trout are mentioned below

1. Brook Trout (Salvelinus fontinalis)

The brook trout or speckled trout is the only trout native to North Carolina. This member of the char family is found only in Coldwater streams of the mountains. Often a brilliantly colored fish, it is readily identifiable by the white leading edge, backed by black, on its lower fins.

2. Steelhead Trout

This anadromous (ocean-going) form of a rainbow trout is born in freshwater streams and rivers in the mountains along the West coast of the US grows to adulthood in the Pacific Ocean and returns to freshwater to spawn.  Because of the time they spend in the ocean, they typically reach much larger sizes than their landlocked cousins, though they are less colorful.

3. Brown Trout (Salmo trutta)

Brown trout, native to northern Europe, was introduced into this country from Germany and Scotland in the late 1800s. Brown trout can be well-known for their brownish-yellow color and the scattered black, red, and orange spots on their sides. The typical brown trout taken from North Carolina water is 12 inches or less in length, but fish greater than 18-inches long are occasionally taken. Brown trout are extremely wary and are the most difficult of trout to catch.

4. Cutthroat Trout (Oncorhynchus clarki)

Cutthroat trout are indigenous to the Rocky Mountains.  They get their name from the distinctive red coloration around their throat, and they were first described to the scientific community by the Lewis & Clark expedition.

5. Golden Trout (Oncorhynchus mykiss aguabonita)

Golden trout are found in the upper elevations of the Sierra Nevada Mountains.  They are a subspecies of Rainbow Trout.

6. Palomino Rainbow Trout

Golden rainbow trout and palomino rainbow trout are not sterile hybrids; they are simply color variations of rainbow trout (Oncorhynchus mykiss) and should not be confused with the golden trout (Oncorhynchus aguabonita) native to a few drainages in California. It took selective breeding for several generations to result in the development of true breeding golden rainbow trout. Typically, these fish are more of a brilliant golden color than the palomino rainbow trout, which has a color phase intermediate between the golden and normally pigmented rainbow trout.

7. Bull Trout (Salvelinus confluentus)

Bull trout are in the char family.  They are usually found in the higher elevations of the Western US mountains, from Alaska to Nevada.

8. Lake Trout (Salvelinus namaycush)

Lake trout, found primarily in lakes in the northern parts of North America, are members of the char family. They are typically found deep in lakes, and they are often caught by trolling.

9. Dolly Varden (Salvelinus malma malma)

Dolly Varden, named for a character in Charles Dickens’ book known for wearing colorful clothes, is also a member of the char family.  They are typically found in the northwest US (Alaska) and even Russia.

10. Tiger Trout (Salmo trutta X Salvelinus fontinalis)

Tiger trout are a cross between a brown trout and a brook trout.  These are extremely rare in nature.  The fish is irregular in the wild, with the brook trout having 84 chromosomes and the brown trout 80.

11. Triploid Trout

Triploid rainbow trout are named triploid because they possess three sets of chromosomes which render them sterile. The triploidy process involves the heating of eggs at 26 to 27 degrees C for 20 minutes at 20 minutes after fertilization.

12. Apache trout

The Apache trout, Oncorhynchus apache, is a species of freshwater fish in the salmon family of order Salmoniformes. It is one of the Pacific trout. The Apache trout measures in length from 6 to 24 inches (61 cm), and weighs between 6 ounces and 6 pounds (2.7 kg). They are a yellowish-gold color with a golden belly and have medium-sized dark spots that are evenly spaced and that may extend below the lateral line and onto the dorsal and tail fins

13. Gila trout

The Gila trout (Oncorhynchus gilae) is a species of salmonid, related to the rainbow, native to the Southwest United States. They have a yellow body, with black spots. The average total length is about 300.0 mm (11.8 in.); with a maximum total length of approximately 550.0 mm (21.7 in.). Gila trout can be found in small mountain water streams, and in confined pools.

14. Donaldson Trout

The Donaldson trout was developed by the University of Washington thru selective breeding and nutrition, to attain a large body size in a short amount of time.  Trout usually reach sexual maturity in about 4 years and weigh 1 1/2 pounds.  The Donaldson, however, mature is two years and weighs up to 10 pounds, and they are prolific in producing more eggs.

Health benefits of Rainbow trout

The rainbow trout (Oncorhynchus mykiss) is a type of trout and a species of salmonid that originated in the cold-water waters of the Pacific Ocean in Asia and North America. The freshwater varieties have been introduced in the Great Lakes of North America. The American Heart Association recommends eating a 3-ounce serving of cooked fish at least twice a week. Rainbow trout is one of the healthiest fish you can include in your diet. One can maximize the health benefits of eating rainbow trout by cooking it from a variety of methods like steaming, grilling, broiling, or baking. Here are a few of the health benefits of rainbow trout:

1. Excellent alternative for protein

If you are searching for a new food that increases your protein diet besides chicken, beef, and pork then Rainbow trout can be your new source of protein. A three-ounce serving of cooked rainbow trout consists 19 grams of protein. The Institute of Medicine recommends that you get between 10 to 35 percent of your total calories from protein. That means if your goal is to consume 1,800 calories per day, 180 to 630 of those calories should be from protein. According to the U.S. Food and Drug Administration, each gram of protein had 4 calories. Men should get about 56 grams of protein per day and women should consume about 46 grams of protein.

Protein consumption is vital for your body’s normal function. They are vital building blocks for muscles, skin, hair, nails, skin, blood, and cartilage. Most of the enzymes in your body that help you function properly are made of protein.

2. High in omega-3 fatty acids

Many “health gurus” tell people to stay away from fat. Anyway if you are trying to lose weight or gain weight, you need to consume fat. However, not all fats are created equal. You should stay away from some fats and gravitate to others. One of the fats you should gravitate to is the omega-3 fatty acids. The ratio between omega-6 fatty acids to omega-3 fatty acids is significant for healthy aging. It cannot be made in the body. Therefore, you must eat foods like rainbow trout that contain the rich nutrient.

A cooked serving of farmed rainbow trout consists of about 999 milligrams of omega-3 fatty acids eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA (found in fatty fish and algae). That far exceeds the 250-500 milligrams per day recommendation that the World Health Organization recommends. Also, that same serving contains only 245 milligrams of omega-6 fatty acids.

Rainbow trout can help balance out that omega-6 to omega-3 ratio. A balanced ratio can contribute to reducing the risk of heart attacks, heart disease, depression, anxiety, breast cancer, prostate cancer, and colon cancer.

3. Rich in potassium

Potassium is one of the most underrated minerals. Many people believe that if you simply decrease your salt intake, then your risk of high blood pressure would decrease. That is not true. Your body balances its salt by looking at its potassium to sodium ratio.

On a typical day, adults over the age of 19, teens between 14 to 18, and pregnant women should consume 4,700 milligrams of potassium each day and should consume no more than 2,300 milligrams of sodium each day, according to the Centers for Disease Control and Prevention. Rainbow trout contains 381 milligrams of potassium and 47.6 milligrams of sodium. That is an 8 to 1 ratio between potassium and sodium!

A potassium-rich diet not only helps manage high blood pressure, but provides relief from stroke, kidney disorders, anxiety, and stress. Potassium has also enhanced muscle strength, metabolism, and nerve function.

4. Good source of Phosphorus

Phosphorus is the second most abundant mineral in the body behind calcium. Phosphorus and calcium work together often to help maintain the integrity of bones and teeth, which is why 85 percent of the body’s phosphorus can be found in the bones and teeth. A phosphorus-rich diet plays other roles like facilitating an efficient digestive system by stimulating digestion with riboflavin and niacin and helping the proper release of waste while keeping the kidneys healthy. Also, phosphorus is the needed for the growth, maintenance, and repair of all tissues since they are needed for genetic building blocks, DNA and RNA.

Most people consume enough phosphorus in their diets. According to the Institute of Medicine, adults are recommended to consume 700 milligrams of phosphorus per day. Kids and teens between the age of nine and 18 are recommended to consume 1,250 milligrams of phosphorus per day. Rainbow yellow trout contains 226 milligrams of phosphorus each serving.

5. Excellent source of the B-vitamin complex

Thiamin, niacin, vitamin B6, vitamin B12, and pantothenic acid are categorized in the B-vitamin complex. Water-soluble vitamins play a major role in cell metabolism. Thiamin assists in the breakdown of sugars and amino acids to make them readily available for the body to use. Niacin helps the body break down carbohydrates, fats, and proteins into energy. Niacin also plays a role in removing harmful chemicals from the liver and makes various sex and stress-related hormones in the adrenal glands.

Vitamin B6 helps the body make several chemicals that help one brain cell communicate with another brain cell called neurotransmitters. The neurotransmitters in production are serotonin and norepinephrine, which can also influence your mood and the body’s internal clock.

6. Good source of the forgotten selenium

Not many people have heard of selenium, but selenium is an important trace mineral for normal brain function, a healthy immune system, and fertility for both men and women. Combined with vitamin E, selenium can act as an antioxidant and may reduce the risk of cancer and prevent sunburn. The most common place people may get their selenium intake is in mushrooms since selenium is found in soil but rainbow trout is a good source of selenium as well.

Children above the age of 13 and adults should consume 55 micrograms of selenium per day. Rainbow trout consists of 12.7 micrograms or 18 percent of the daily value of recommended selenium.

7. Low in contaminants

According to the Environmental Defense Fund, farmed rainbow trout is low in mercury and polychlorinated biphenyls or PCBs. Fish that contain high levels of mercury or PCBs may cause side effects like kidney damage, mental disorders, brain damage, and fatigue, especially in children and fetuses. Seafood Watch recommends avoiding wild-caught rainbow trout because of the increased risk of pollutants.

How to Eat

  • Fresh rainbow trout can be baked whole or as fillets.
  • Frozen rainbow trout can be cooked without being thawed if you can spare the additional cooking time.
  • Rainbow trout are great to grill, fry, or broil. Rainbow trout is a great fish for people new to seafood, as it is quick and easy to prepare.

Other Facts

  • Largest trout species is the lake trout, a native of the Great Lakes, Alaska, and Canada that can weigh as much as 100 pounds.
  • Rainbow trout are able to spawn at age 3 and usually only spawn every 3-5 years.
  • Rainbow trout is considered endangered in some regions by the United States Federal Government because they are largely affected by stream damming, and sediment runoff.
  • A group of rainbow trout is called a hover.
  • If a rainbow trout migrates to the ocean in adulthood instead of staying in streams and rivers, it is called a steelhead. Their body is almost entirely silver.
  • The biggest rainbow trout ever caught was in Canada in the year 2009 and weighed 48 pounds.
  • The average lifespan for a rainbow trout is 4 to 6 years in the wild.
  • Spawning season for rainbow trout occurs in the spring.
  • Rainbow trout has been introduced to every continent except Antarctica.
  • The color of rainbow trout meat will vary with diet and environmental conditions.
  • Rainbow trout have been commercially farmed since 1870. The largest producer of farmed trout is Chile.
  • A female trout can spawn from 200 to 8,000 eggs during season.
  • Rainbow trout are indicators of water pollution because they can survive only in clean waters.
  • They spawn in the streams where they were born.
  • The fish has sharp teeth on the roof of its mouth but has no lower teeth at all.

Buying of Rainbow trout

Fresh or frozen rainbow trout have the same nutritional value. Your local grocery store or fish monger should have fresh rainbow trout available throughout the year.  If you are buying fresh trout, select a whole or filleted fish that has shiny scales and is firm and somewhat elastic to touch. Fresh rainbow trout will have a mild odor but it shouldn’t smell fishy.

If buying frozen rainbow trout, avoid any fillets that show signs of brown discoloration or dried out edges.  Select a package of frozen rainbow trout that has little or no air trapped inside to minimize freezer burn.

Storing

Wrap fresh rainbow trout in plastic wrap or store in an airtight container in the refrigerator for no longer than one or two days.

For longer storage, label the packaged rainbow trout with the date of purchase and freeze it for up to two months.

Preparing

Fresh rainbow trout can be baked whole or as fillets. Frozen rainbow trout can be cooked without being thawed if you can spare the additional cooking time. (Thawing frozen rainbow trout in cold water takes about 30 minutes per pound.)

To bake fresh rainbow trout, preheat the oven to 450°F (230°C). Rinse the fish and pat it dry with a paper towel. Place the whole or filleted trout in a baking pan, brush with olive oil and season to taste.

Estimate the thickness of the rainbow trout and bake for 10 minutes per one inch (2.5 cm) of thickness. Flip the trout half way through the cooking time, unless it’s less than half an inch (1 cm) thick.

If you’re cooking rainbow trout wrapped in foil or sauce, add five minutes to the cooking time.

Rainbow trout that’s opaque and flakes easily with a fork is ready to be enjoyed.

Precautions 

  • The consumption of sea fish if one is trying to reduce inflammatory diseases such as heart disease.
  • Farmed ones contain arsenic that leads to arsenic poisoning.
  • Seafood should be cooked safely in order to prevent foodborne illness.
  • Pregnant women, young children, older adults, people having lower stomach acid and compromised immune systems (HIV/AIDS, liver disease, cancer, diabetes, gastrointestinal disorders, people taking steroids, chemotherapy, or immune system) are prone to higher risk.
  • It might be contaminated with bacteria such as Vibrio parahaemolyticus, Vibrio vulnificus, and other bacteria relate to land use, sewage discharges, runoff, etc. These microorganisms occur naturally in warm coastal waters which could cause even death or serious illness in individuals who are at higher risk.
  • Listeria monocytogenes could cause a serious foodborne illness known as listeriosis.
  • The virus Hepatitis A could survive in light cooking. So one should consume it after being properly cooked.
  • Fish could have toxins that could cause illness such as ciguatoxin and scombrotoxin, or histamine poisoning.
  • Sea fish is related to Scombrotoxin (histamine) which develops when fish is not kept cold enough. The symptoms develop quickly and also disappear completely within 24 hours.
  • The flesh of tropical marine fishes might cause ciguatera poisoning experiencing gastrointestinal maladies that could last for several days, weakness in arms and legs, and reversal inability to differentiate between cold and hot. The symptoms could persist for weeks.
  • Farmed seafood results in to increase in inflammation leading to weight gain, arthritis, and heart diseases.
  • The imbalance ratio of Omega-6 and Omega-3 causes heart disease and hypertension.
  • Seafood and fish in farms have polychlorinated biphenyls (PCBs), organophosphorus (OPs), organochlorine (OC), trifluralin pesticides, and hexachlorobenzene (HCB) causing diseases or even death.
  • The seafood has a high content of mercury, which may lead to mercury toxicity.
  • Consume it in moderate amounts. So consume it with caution or Avoid consuming it raw.
  • Some people might get allergic reactions. So avoid it.
  • It has a high chance of contamination.
  • One should limit its intake.
  • Consult the doctor by pregnant women and children before consuming it. Children and pregnant women should avoid it because the high content of mercury might cause a negative impact on the development of the nervous system of a fetus.
  • Seafood or fish have purines in it which is harmful to people having purine-related problems. Excess purines result in an excess buildup of uric acid that could lead to the formation of kidney stones as well as gout.
