How large do salmon get? The largest Atlantic salmon was 105 pounds and 60 inches. However, depending on how long they are at sea, adults returning to the Gulf of Maine rivers typically weigh approximately 7-12 lbs and are 28-32 inches long after 2 years at sea.
The size and weight vary depending on the species. The length of a mature salmon can range from between 20 inches to almost 5 feet. Adult salmon can weigh anywhere between 3 pounds to over 100 pounds. Chinook salmon are also the largest of the species, with the heaviest recorded weighing 126 pounds. Meanwhile, pinks are the smallest of Pacific salmon with an average weight of 3.5 to 4 lbs.
During the mating season, their appearance changes to attract a spawning mate. Males often have brighter coloring than females. Depending on species, many males also develop humps and hooked jaws, known as kypes. For example, sockeye salmon turn bright red on their body, and olive green on the head. The males develop a prominent hump in front of the dorsal fin, their snout becomes elongated, and their canine-like teeth grow out of the receding gums. Meanwhile, females undergo a distinct color change but retain their body shape, according to the Washington Department of Fish and Wildlife (WDFD).
Many species of salmon are listed by IUCN’s Red List as “Least Concern.” However, certain populations of sockeye salmon, coho salmon, chinook salmon, and Atlantic salmon are listed as endangered. The most endangered species of salmon is most likely the sockeye salmon from the Snake River. Coho salmon in the lower Columbia River may already be extinct. Salmon are not endangered worldwide.
After spending one to five years at sea (depending on the species), sexually mature salmon return to freshwater to spawn. Accompanied by a male, the female uses her tail to create a depression in the riverbed, known as a redd. To fertilize the eggs, the male then deposits milt, or sperm. After the female covers the depression with gravel, she moves on to create a new redd. During the spawning period, one female may create up to seven separate redds and lay between 2500 to 7000 eggs.
Man-made dams and reservoirs threaten salmon numbers in the wild by blocking their paths, creating obstacles for young salmon heading for the ocean and adult salmon returning to their spawning grounds. Overfishing, habitat loss, and a number of changing environmental conditions also continue to affect many salmon populations. For instance, rising river temperatures have been connected to an increase in marine illnesses that adversely affect salmon growth.
The Atlantic Salmon (Salmo salar) is a very delicate fish, hence its presence is a good indicator of the health of an ecosystem. The fish is widespread in the Northern Atlantic oceans and surrounding rivers. Its life stage is full of unique names such as smolt, parr, fry, and alevin: depending on whether it is in the freshwater or saltwater phase. Atlantic Salmon are members of the family Salmonidae migrating between the sea (feeding grounds) and rivers (breeding grounds). Adults are identified by their predominantly black spot above the lateral line plus highly developed teeth. Besides, they change appearance when they enter freshwater or salty water.Dimensions & SizesDimensions & Sizes

How long do salmon live?
After the female covers the depression with gravel, she moves on to create a new redd. During the spawning period, one female may create up to seven separate redds and lay between 2500 to 7000 eggs. Salmon live anywhere from 2 to 8 years, depending on the species.
What is a healthy amount of salmon to consume per month?
This will depend on what type of salmon you consume. The United States Environmental Protection Agency (EPA) does not recommend eating salmon more than twice a week due to several types of contaminants present in the fish (if it is salmon from aquaculture, this number increases to once a month). Compared to aquaculture, wild salmon has lower levels of PCBs and better nutrients, however, its price comes to cost almost twice as much, in addition to being more difficult to find this product on the market. Consuming canned salmon is also a good tip – this is because, for the most part, it is of wild origin (apparently, farmed salmon does not keep well when canned).
How long do salmon spend at sea?
Some pass into unscreened irrigation ditches and become stranded in farm fields. The amount of time that salmon spend at sea varies by species: Chinook, Sockeye and Chum: spend 3 to 5 years at sea. Coho: most spend 3 years at sea. Pink: spend exactly 2 years at sea.
What is the life cycle of a salmon?
They are anadromous fish, meaning that they spend part of their lives in freshwater and part in saltwater. The life cycle of salmon begins when adult fish migrate up rivers and streams to spawn. The female salmon will lay her eggs in a nest, or redd, which she creates by using her tail to clear a depression in the riverbed.
