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...

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.

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.
The PBS documentary begins by explaining the normal life cycle of salmon, focusing primarily on the sockeye salmon population. This Pacific salmon once was found abundantly in the Columbia and Snake River, but as rivers were straightened and dams were built to meet the needs of population growth the fish population has diminished by the thousands.
Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.
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...

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.
The fish is modified to carry a growth hormone gene from the Pacific chinook salmon and DNA from the eel-like ocean pout. This allows the salmon to grow faster as the hormone is kept active all the time.

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.
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.
There is one species of Atlantic salmon and five species of Pacific. Atlantic salmon account for almost 95 percent of the farmed salmon produced, and most of them are farm-raised on the pacific coast. Pacific species account for all of the wild salmon caught in the Americas and some of them are also farm-raised. No wild Atlantic salmon are fished commercially in North America, as they are an endangered species. 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.
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
