Chinook salmon

Biology and Ecology: The introduction of non-native species may pose significant dangers to the local ecosystems and the Asian carp is one of them. Asian carp is the common term for the species of grass carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis), black carp (Mylopharyngodon piceus) and silver carp (Hypophthalmichthys molitrix) (Michigan Department of Natural Resources 2012). In the United States, the Bighead Carp have greatly affected the river ecosystems that it…

The Pacific Northwest was once full of an abundance of untapped resources, it was barely populated and was the definition of a hinterland. As the Pacific Northwest started to become known and resources started to become majorly exploited and shipped, we slowly become what we are now, not a hinterland. After all the overuse and misuse of the land we are not and will never hinterland again. The definition of a hinterland is defined as parts of the country that is less developed and…

calculated that 39,000 tons of salmon washed up near the island of Chiloe in Chile. Six months later the government and the public have yet to reconcile their beliefs on the cause of the incident. According to Soberanes and Perez’ article, “The salmon crisis in Chile’s Chiloe Island,” government officials blame a “red tide” of algae as the main cause of the fish kill, completely independent of government authorization for the salmon industry to dump 9,000 tons of dead salmon off the Chilean…

Goldfish Facts Find here the proven Goldfish facts of the species known as 'chin-yu in China, 'kingyo' in Japan, 'goldfisch' in Germany and 'poisson rouge' in France. It's hardy nature and bright coloration will continue to endear it to future generations of fishkeepers, who will enjoy the challenge of maintaining and developing the more fancy and bizarre varieties. Today, millions of goldfish are bred every year in North America, the Far East and Europe for distribution to fishkeepers around…

The invasive effects of Dreissena polymorpha on native mussels within the Great Lakes region The Great Lakes area once supported an abundant number of freshwater mussels (Mollusca: Unionacea). The invasion of Zebra mussels (Dreissena polymorpha) has decimated these populations, by outcompeting native mussels in dispersal rates, and reproduction, due to enhanced survival mechanisms. Understanding the mechanisms that have allowed Zebra mussels to out complete native fresh water mussels, will…

Oct.2,2015 Pacific pink salmons I believe that pacific pink salmon are important because they help the ecosystem. Salmons are very common fish. All kinds of animals eat salmons because they have protein.Salmon are very popular because they ar research for human beings. Salmon spend most of their live time in freshwaters before they go…

The Upstream Journey At the peak of fall, anadromous salmon begin their upstream journey to go back to their birthplace and reproduce the next generation. Some swim seven hundred miles, and face adversity of all kind: hunters, bears, and eagles. Anadromous salmon have an inherent sense of smell, or direction, and of their long term goal. They adapt and change based on whatever environment they are put in. Nothing can keep salmon from reaching their final destination; because they are resilient…

time. Wild salmon is normally travelling between fresh water to ocean water. But Sea lice could not stand on fish when the salmon travelling in fresh water and this is a natural way to remove sea lice from fish. Though in ocean, farm salmon continuous captive in cages and cannot access to fresh water and this increase of getting more sea lice. European Food Safety Authority (EFSA) mentioned that, “Sea lice is known as biggest welfare and economical risk for salmon at farms in the marine…

There are three kinds of masks, the single face mask, the mechanical mask, and the transformation mask. The single face mask is a single piece of wood. A mechanical mask is built with strings or hinges (after Europeans), which might allow a mask to open and close it~s mouth or eyes. The transformation mask is the most complex kind of mask. It consists of an outer mask that opens up to reveal an inner mask form, which might also open up to reveal a third mask form! Transformations masks are…

due to their increased growth rates. Also, these transgenic fish require less food than wild fish resulting in the need for less baitfish to feed them. Genetically modified baitfish can also provide a cheaper alternative because for every pound of salmon being harvested, it requires several pounds of baitfish. Another positive outcome of genetically modified fish for fish harvesting is their change in cold tolerance. This allows farmers to expand their farms to areas that are less populated and…
