Salmon typically die after reproduction due to exhaustion from the effort of reaching mating areas. Salmon populate the northern Pacific and Atlantic oceans and can be found in fresh water lakes and rivers in the northern U.S. Salmon have excellent eyesight and can judge distance even with targets outside the water, such as bugs.
Pink or humpback salmon is the most basic variety of salmon, often processed into packaged foods. Light pink, mild tasting, and low in fat, it is recognizable by its distinctive humps when spawning. Chum salmon is one of the smallest varieties, at around 8 pounds. It is mainly used for its large roe, available in jars or frozen, but you may see it in fillet form under the name keta salmon.

The Atlantic salmon (Salmo salar) has long been associated with human cial fishing records going back centuries (Waite, ; Shearer, ; Summers, ) record catches of two morphs, the smaller grilse and the larger the early 20th century, when it became known that fish could be aged by growth rings on their scales (Calderwood.
The prevalence of Kudoa thyrsites, a cause of post mortem soft flesh in Atlantic salmon (Salmo salar), was determined for 17 harvests of Atlantic salmon (Salmo salar) raised in British were divided into two categories, sexually immature and sexually mature (grilse), using criteria typically employed at processing plants, i.e., external morphology.
adult Chinook salmon appear to be the most frequent species infected with aquareovirus A or B. The virus has also been isolated from adult coho and chum the virus resulting in mild hepatitis with no overt disease or mortality.
In Alaska, aquareoviruses have been isolated from Chinook salmon (species B) and geoduck clams (species A). 1. Introduction. Atlantic salmon (Salmo salar L.) are widely distributed in the Northeast Atlantic ocean, and one important feeding area for salmon is the central and southern Norwegian Sea, i.e.
the area north of the Faroe Islands (Jákupsstovu, ).This area is characterised by a front that separates the warmer Atlantic water from the southwest, and the colder and less saline Arctic water.
Until the early s the Svir River freshwater population of Atlantic salmon (Salmo salar Linnaeus, ) was the largest in the Ladoga Lake basin.
A catastrophic decrease in the salmon abundance took place due to loss of spawning grounds after the dam construction in the riverbed and a long-time timber rafting in the main tributaries.
