Interannual Variability in the feeding and condition of Subyearling Chinnok salmon off Oregon and Washington in relation to fluctuating ocean condition What did you want to learn?
The decreasing amount of Chinook salmon in the world due to humans catching and consuming the fish. The fish is about to go on the endangered list. This fish is important to its natural habitat and located in the Pacific Ocean. Also another factor is ocean warming up which is affected by El Nino.
Chinnok salmon is a particular type of spices which is important to the ocean. There are many different types of Chinnok salmon species. But the two types of Chinnok Salmon are Subyearing and Juvenile. Chinnok Salmon is found in the…show more content… The fish is an important species when it’s born and survival rate is important to life. In the early stages when the juvenile and Chinnok salmon travels through the ocean it see the plankton, ocean condition and prey and eventually eats. The ocean conditions affect the eating habits and body. This fish has the highest rate of mortality. When adults of Juvenile and Chinnok survival rates are very high when they return back from the warm ocean water back to cooler water. Other factors like characteristic body, stomach changes in the…show more content… They also used chemicals

Salmon were caught at sea using a rope that was wide and went down to the deep part of the
ocean. After they caught the fish it was transferred in a lab and dissected with a microscope. When they
caught the fish they were measured at (4 length to 1mm). They cut open the stomach and used chemical
called formalin that were used between (2008-2012). They also used another experiment which is
ethanol.
Data Analysis
They examined Chinnok salmon which they grouped them into two categories A Subyearing and Juvenile. They examined 4,581 salmon which average length if 167.9 which they found in the ocean.
(2016 John Wiley & Sons Ltd, Fish. Oceanogr. 26:1,1–16.)
The sub yearlings salmon which is found 7kn near the shore line. They examined 2,140 stomachs and found out 93 were empty. (2016 John Wiley & Sons Ltd,
Fish. Oceanogr. 26:1,1–16.)
After conclusion and analyzed the Chinnok salmon diet it was 87.5. While another type of
