In this paper I will explain the life of salmon and discuss the environment that they live in. I
will break down information that describes various kinds of salmon that specifically live in the
Kenai River and inform you about different situations that will effect the salmon population.
There are many cool facts about salmon. The largest salmon caught weighed a hundred and
twenty six pounds. Salmon are called "fry" when emerging from their eggs. Salmon can travel up
to 3,500 miles just to spawn and they usually lay around 2,500 eggs, although it is possible for
them to lay up to 7,000 eggs. A few different types of salmon are the King Chinook Salmon,
Silver Salmon, and Pink Salmon, Red Sockeye Salmon, and the Chum Keta Salmon.
The King Chinook Salmon is the largest species in the Pacific salmon (Oncorhynchus) genus.
It's taxonomy is Animalia, Chordata, Osteichthyes, Salmoniformes, Salmonidae, Oncorhynchus,
tshawytscha. This salmon can become anywhere between forty to a hundred and twenty pounds
and reaches up to three feet in length. It feeds off of insects, amphipods, and other crustaceans
while young, and mainly fish as adults. The King Chinook Salmon has a variety of green, blue,
and silver colors along it's back.
The Silver Salmon is also known as the Coho Salmon. It's taxonomy is Animalia, Chordata,
Osteichthyes, Salmoniformes, Salmonidae, Oncorhynchus, kisutch. This salmon is colored a
dark metallic blue or green, with lighter colored bellies. Coho feed off of plankton and
underwater insects/ small fish. An interesting fact about this fish is that it's lifespan remains
unknown.
Pink Salmon is often called humpback salmon or humpy. It is the smallest and most c...

...omes to the
salmon population degrading. Building dams and barriers are a part of loss of freshwater and are
not good because they are being built in many river ecosystems which causes a blockage for
salmon to enter their habitat.
In conclusion, I talked about the different types of salmon and described the Kenai River
environment. I discussed different scenarios involving humans and predators that could hurt
the salmon population. I learned that we could do lots of things to protect the salmon population.
For example, by simply not building anything on the Kenai River, we can prevent blocking the
path salmon take while migrating from freshwater to the ocean. There are many situations where
humans affect marine animals, whether they know they are hurting them or not, and we should
seek further ways to put a stop to this.

T. californicus is found from Alaska to Baja in small, shallow tidepools and tidal flats in the upper spray zone where they cannot avoid the full effect of visible and ultraviolet (UV) radiation. Individuals assemble in areas of lower radiation at midday, yet have no preference to the intensity of light at dawn and dusk (Hartline and Macmillan 1995). These tiny arthropods inhabit all types of marine sediments from sand to fine mud and ooze. Along with plankton, T. californicus eats microscopic algae, protists, bacteria, diatoms, algae and microbes (McGroarty 1958). When the concentrations of the species in their habitats are high, T. californicus will turn to cannibalism for a food source. The nautilus eye present in the species is rich with fatty acids and provides a good food source for the animal.

In the past, because the glaciers disappeared slowly can make people have a low temperature, clean water during the summer, but at the same time the salmon begin and end their lives. With temperature getting warmer and our glaciers melting, every stage of salmon’s life cycle is getting hurt.
This loss of salmon life in the river system greatly affected the nutrient levels in the rivers. As stated in the film, the sockeye provided

The salmon are all sterile females which are grown in contained land-based systems, therefore they will not be able to breed among themselves or with other fish. So it is unlikely that the fish will have an impact on wild populations.

Since three-forth of the world is composed of bodies of water, it’s natural that a great number of people rely on fishing for their livelyhood or just for their recreation needs. There are numerous of fish species swimming under the lakes, seas, ponds, and rivers. Most anglers consider fishing as the delight in their purpose-driven life, a sport, as they say.
Since this first encounter I have caught lots of these magnificent fish and as the years go by they seem to keep getting bigger and bigger. I have developed several baits and presentations that help me to catch these fish and I would like to share them with you.
Atlantic salmon have become the species of choice to raise on farms because they are more adaptable to the farming techniques and make better use of feed so they produce more salmon with less feed. Not everybody agrees however, that farmed salmon raised in net pens are healthy for the environment or for you to eat. Over the years, there have been numerous stories in the media that have pointed out the negatives of farm raised salmon. These arguments have ranged from wastes from salmon farms, the spreading of disease from farmed to wild fish, the negative impacts of farm raised fish escapes and interacting with native fish, and recently, the effects of farmed salmon consumption on human health. The latest issue that the media got there hands on and consequently got the public concerned, was a report that polychlorinated... ...
The stories of each fish flow together as each story shows how humans have pushed to gain more control over the ocean and the delicious animals that swim in it’s depths. Greenberg starts in the free-flowing rivers where salmon are commonly found. It is there that early humans of the Northern Hemisphere most likely began their infatuation with fish. Greenberg puts it as, “It(salmon) is representative of the first wave of human exploitation..” (170) Once Europeans learned to fish, they had the ability to fish in shallow ocean water which is where sea bass are usually found. Later, fishermen s...
Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large species, the cod. In the 1950s the Newfoundland Grand Banks was home to a plentitude of cod; early European explorers said,”that if you lowered a basket into the water, cod will fill it to the brim.” It supplied the locals with an item of trade and a source of food.
A selection of primitive fish regulated in diversity due to constant climate change in the sea. Primitive fish are adapted to their general occurrence by converging to low temperate increased by activity in high temperature. This is the result of a natural selection of fish branching off into different species. “Acclimatization has been identified in many invertebrate animals from both high and low latitudes by laboratory acclimation of individual invertebrates has not been much studied.” (Evolutionary biology) Due to their enzyme activities, and feedback mechanisms depending on the environment that fish reside in, its way of coping with temperature change. During ecological expansion, most fish change life cycles of primitive fishes. (Evolutionary
