 Article posted January 4, 2012 at 09:22 PM GMT0 • comment • Reads 1180 There is a very confusing question out there. "Which came first, the chicken or the egg?" Well wouldn't that work with any animal that lays eggs? Of course it would! So I am going to go through the entire salmon life cycle to find out which came first, the salmon or the egg? The Egg Stage Salmon eggs are usually a reddish orange color. They have a black dot right in the middle. This is the salmon egg's eye. The mother protects the eggs by digging a hole, like a burrow, called a redd. The eggs are then shielded by a layer of gravel. Eggs are threatened by predators, pollution, high temperature, and gravel disturbance. They need cold water and lots of shade. Alevin stage Alevin is the second stage of the salmon life cycle. They are small and have a little sac hanging from their belly. This is a yolk sac. The little fish are fed this through their yolk sac. They are theatened by gulls and other big fish like trout. Alevin need gravel to hide from predators. src="http://educatoral.com/rm604/images/per5/g1/marcusalevin.jpg" width="400"> Fry Stage Once salmon hit the fry stage, they start to look like normal fish. They need lots of woody debris to hide under. They also need a cold environment with sediment free gravel. Loss of riparian habitat is a huge threat to salmon. Riparian habitat is The community of plants around water that is concentrated.This is really important to salmon. src="http://educatoral.com/rm604/images/per5/g1/marcusfry.jpg" width="400"> Parr Stage The parr stage of the salmon life cycle is an interesting one. They grow black stripes on their backs for camouflage. Parts are threatened by loggers and especially blue heron. They need their parr marks to protect themselves from predators like birds. Parr need lots of food. src="http://educatoral.com/rm604/images/per5/g1/marcusparr.jpg" width="400"> Smolt Stage Smolts look almost exactly like parrs exept they don't have parr marks. Smolts are often sucked up in hydroelectric dams. That's why people put up nets to scare the smolts away from the dams. The smolt stage is usually when they start to swim to the ocean, but they can't be exposed to salt. So they start to grow a grey skin color that is salt tolerant. src="http://educatoral.com/rm604/images/per5/g1/marcussmolt.jpg" width="400"> Adult Stage The adult stage is the second to last stage of the salmon life cycle. Adults are threatened by orcas and seals, and there is a huge fish out there called white sturgeon and they grow huge by eating tons of salmon. So those are threats too. src="http://educatoral.com/rm604/images/per5/g1/marcusadult.jpg" width="400"> Spawner Stage The spawner stage is the last stage of the salmon life cycle. Once they reach the spawner stage their mouths curve upward and they grow sharp teeth to defend their spawning grounds. Once they spawn, they die. src="http://educatoral.com/rm604/images/per5/g1/marcusspawner.jpg" width="400"> So, I guess, even by going through the entire salmon life cycle, we don't know which came first the salmon or the egg.

description

the salmon eggs hatch in about 3 months and are laid in reeds made by the female.the eggs are an orangish pink color and about the size of a pencil eraser,they have one eye in the middle of the egg.

threats

the threats are invasive species,disease,freezing,flooding,preditation,high temeratures ,dams,waste,humans,disturbance of gravel,soil eroison etc.

needs

salmon eggs need cool,clean water to survive.Trees and plants along the river provide shade which keeps the water temerature cool enough. The treets and plants along the river also help prevent soil eroison which can sometimes smother the eggs.

 Article posted January 23, 2012 at 09:03 PM GMT0 • comment • Reads 1163 upon reaching their birth rivers and streams, the adult salmon re-adapt to the fresh water and begin their upstream journey to their natal stream where they were born. At this time, they cease to feed and live on the stores of fat within their bodies. Their upstream journey is a challenging one, swimming upstream against rugged rapids, laeaping over rocky waterfalls, traversing fish ladders, avoiding fisherman nets and hooks, and staying clear of hungry bears. Whey finally reach their natal stream they have reached sexual maturity and are ready to spawn. The female adult clears a spot in the streambed by sweeping her tail back and forth creating a gravel nest that is referred to as a redd. She will then layin this redd and the male adult salmon will fetilize and protect them until both salmon die within a couple of weeks and leave the embryos to fend for themselves.

After eggs are fertilized by the male, the female covers the eggs with small to pebble sized gravel. Gravel covering allows water to flow around the eggs and keep them healthy. Redds are fragile and can easily be destroyed by people or animals crossing the shallow river or by dirt being washed or knocked into the water and smothering the eggs. Salmon eggs need cool, clean Water to survive. Trees and plants along the side of the river provide shade which keeps the water temperature cool enough for the salmon eggs. Trees and plants also prevent soil erosion which will sometimes smother the eggs. ALEVIN The eggs are laid in the fall and hatch the next spring. The small larval fish, about one inch in length are called Alevin and still have a yolk sac attached. The yolk sac contains protein, sugar, minerals, and vitamins. The Alevin live on this "lunch bag" for a month or so before emerging from the gravel and beginning to hunt for food themselves. When the Alevin completely absorbs their yolk sacs, if they leave the gravel before their yolk sac is completely absorbed they are commonly called button-up fry. Alevin need cold running water that is rich in oxygen and clean gravel that has spaces where the Alevin can hide. Threats include predators in the water, siltation, pollution and floods or other activities that can disturb the gravel can be very harmful, so people can protect the Alevin by keeping dirt or other pollutants out of the water and by staying out of the gravel! FRY The young salmon fry begin to move in schools and feed in the river. They feed mainly on zooplankton until they grow large enough to eat aquatic insects and other larger foods. Some species of salmon fry, such as chum and pink, start downstream toward the ocean immediately after emerging from the redd; others stay in fresh water for up to three years. Land-locked salmon, such as Kokanee, never migrate to the sea but live their entire lives in fresh water. Loss Riparian habitat along streams, rivers, estuaries, and bays is one of the most serious dangers to the wild salmons survival. SMOLT As the salmon parr begin migrating toward the sea, they will, they will begin the smoltification process. The smoltification process refers to The changes that take place in salmon as they prepare to enter the sea. These changes include the development of the silver color of adults and the tolerance for salt water. LIFE IN THE SEA The salmon will feed and grow in the sea for the next one to eight year. They will remain in the sea until they reach full maturity. The salmon will also remain silver color until they return to their home stream. JOURNEY UPSTREAM Once the salmon start upstream toward the spawning grounds, Tray do not feed but derive energy from stored fats. The distance salmon travel upstream to spawn varies. The average spawning trip distance is about 150 miles. Article posted January 12, 2012 at 09:22 PM GMT0 • comment • Reads 1109

ALEVIN They hatch in the spring and are about one inch long and have a large yolk sack under there head that gives them nutrients. The alevin dont have near as many threats just bigger fish and other animals. Fry This is the next step in the salmon life cycle and are a little bit larger and dont rely on their yolk sacks anymore and now feed on zooplankton. Their threats now are bigger fish and animals. Parr This is the next step from fry andstart to grow parr marks that camoflauge them in away from predators.They are about 5 inches long and feed off small bugs and worms.Parr do not have many threats because of the parr marks.http://educatoral.com/rm604/images/per5/g7/FryParr.jpg" /> Smolt This is the stage when they adapt to salt water.They start to eat shrimp and squid and will live in the sea for 1 to 8 years.Their threats now is a seal whales and other animals.Also the everyday threat, water pollution.http://educatoral.com/rm604/images/per5/g7/Smolt.jpg" /> Adult Salmon They weigh 2 to 125 pounds in weight and vary from 14 inches to 5 feet in length. Their threats are seals and whale. They do not need to feed small stuff they feed on the small fish they used to be. They also slowly are adapting back to the fresh water.

DANGERS:the danger to them are:having no food, non-cool water, gravel with sediment and many types of birds, and other predators, erosion, and pollution are some of the treats to the frys. NEEDS: they need:food, cool water, sediment-free gravel,trees (for shade and to keepback sediment and help prevent eroision.) and plants.

DANGERS: some of the dangers to eggs include: hikers, loggers, fishermen, livestock, and wild animals all somtimes crush or destroy the eggs and/ or the redd. NEEDS: eggs need cool, clean water and tress to provide shade to col down the water and to hold the soil from eroding and smothering the eggs.

DANGERS: some of the dangers to alevin include: Gulls, Dippers, Sculpins and other predators, and another danger is having no gravel or other substance that they can hide in and being crushed. NEEDS: they need gravel or some other substance to hide them and they also need most of the smae things aas eggs so they need plants to help prevent soil erosion and cool, clean water and trees to provide shade to cool the water, but they dont need food because they have the yolk sack which provides food for about a month.

They have also grown to about five inches and are the last stage of the salmon life cycle before they have traveled into the ocean. DANGERS: the dangers to them include: Hydroelectric dams ,gulls and other birds of prey, and pollution from farms, factories, and citys. NEEDS: they need non-polluted water and someway to bypass hydroelectric dams and they need to have undergone osmoregulation Article posted December 12, 2011 at 09:23 PM GMT0 • comment • Reads 1221

DANGERS: dangers to spawners include: fishermen, and predators such as bears, birds, and wildcats, and some of the things they faced going down.NEEDS: they dont really need much but they do need, fishladders to be able to bypass hydroelectric dams, and clear clean water and they can also climb waterfalls to get higher up  the stream.

See? Salmon eggs! Oh and here is a link 4 a real salmon egg pic! http://www.seymoursalmon.com/images/lifecycle/eggs.jpg And thats a good picture. Anyway, then they hatch into alevin. I know, wierd name. But thats what its called. The alevin have a yolk sack attached to them, and (its really wierd.) the yolk sack stays for a few weeks. While the yolk sack is still not absorbed, the salmon stay in the gravel. When its gone, the alevin come out and they are fry now.and here is a pic of alevin! and here is a pic on a website!! http://www.seymoursalmon.com/images/lifecycle/alevin.jpg now about fry!fry immedietly start looking for food, because they have no yolk sack left. yes this is yukky, but they eat their dead parents. eeew. oh and plus bugs. teeny bugs.

Alvin are the second stage of the life cycle.they do not get food but they do feed of a feed sack for a few months.they are still very fragile and can not fend for themselves. salmon are now on their third stage.at this stage they are getting their own food for their food sack has run out.they also travel in schools of other fry. After being a fry they are now smolts .during this part of their life they mostly changing their body's to adapt to being able to living in the ocean. (sorry it's sideways) Adult salmon will live in the ocean for 1-8 years And will stay there until fully matured.They will remain silver until returning home to spawn. At this stage the salmon are only trying to survive till they have laid their eggs.once they have been laid they soon die leaving the eggs to fend for themselves .

 Article posted November 22, 2011 at 04:09 PM GMT0 • comment • Reads 974 Hello mai pies! In this blog you will get information on the salmon life cycle!     This is a picture of salmon eggs.(I could not find any pictures of eggs in a nest,sorry.)So any way if these eggs were in thier natural habitat the nest they would be in would be called a redd. A hiker,horse back riders,anything that can walk over a nest really.   This is a picture of salmon Alevin. They require cold, clear, oxygen rich water at this stage of life. They stay in the creek or river around their redd becuase they like calm water to collect their food. Would you like being thrown around when you tried to have dinner?   Excessive sediment in water is one of the greatest dangers to salmon at this stage. It can reduce oxygen levels in the water! (that means dead fishy-fishy XD) Salmon parr have vertical marks on their skin. They are known as parr when they are over a year old. They stay in the river or creek they are born in until they are old enough to leave. They stay in the creek or river and eat aquatic bugs and worms. They have the danger of being thrown around if they leave calm water.   (NOTE:the information you are about to read was found on http://cybersalmon.fws.gov/chum.htm. It is about Chum salmon. Not all salmon have the same smoltification process.) Many changes occur when young salmon are smolt. They lose their parr marks and get a new pattern. They get a pattern that is light on the bottom and dark on the top. They have such a short freshwater period, the smoltification process is not as pronounced as other species of salmon. (It is not very flashy. I said that for the pies that don't know the other meaning of pronounced. -.-)   (NOTE:The information in this paragragh and the next one are from this website: http://cybersalmon.fws.gov/chum.htm.) Most Alaskan Chum salmon stay in the ocean for 2-5 years. Their primary diet consits of copepods,fish,mollusks,squid and tunicates. They near spawning stage at 3-6 years old. The dangers of this stage is that fishrmen can catch you in their nets.   As you know now, the Chum salmon return to the place in the river or creek they were born in to spawn. Female salmon make the redd and she mates with a male salmon. When she lays her eggs in the nest, she covers them in rocks and pebbles. After the salmon mate and lay their eggs they die from malnutrition and weakness. The salmon life cycle repeats for the eggs.

 Article posted November 21, 2011 at 04:30 PM GMT0 • comment (5) • Reads 2725 The life cycle of the wild salmon begins with the female salmon digging out a shallow redd,or nest,in the gravel in the river bottom. The eggs that are laid in the fall hatch the next spring.the small larval fish,about one inch in length,are called alevin,and still have a yolk sac attached.The threats are horseback riders, fishermen, loggers, livestock, wild animals, or just the casual hiker can all accidentally destroy salmon redds without even realizing it. Gulls, dippers, sculpins, and trout all feed upon salmon eggs and young alevin. The young salmon fry begin to move in schools and feed in the river.they mainly on zooplankton until they grow large enough to eat aquatic insects and other larger foods.the need is cool, clear, water holds lots of oxygen which the salmon also need.the danger is as the vulnerable fry grow, they will start to develop spots and vertical parr marks on their sides. These markings help camouflage them from predators such as mergansers, and great blue herons. Unlike most fry, pink salmon fry do not develop these parr marks. By the time the salmon reach the estuaries,they have silver sides,bright bluish green backs,and are called smolt. The danger is hydraulic dams and pollution from farms, factories, and cities, the needs are clean water for oxygen and tall trees to shade parts of the stream. During their stay in the sea,the salmon travel hundreds,or even thousand,of miles searching for food and trying to stay out of the mouths of predators.their needs are shrimp, and squid, to eat. Once the salmon start upstream toward the spawning grounds,they do not feed but service energy from stored fats.the dangers are bear, coon, and sport fishermen.the needs are less water pollution less bears and less coons and loose gravel.  The salmon that make it back to their home streams to spawn have beaten amazing odds.on average, out of every 1,000 eggs laid  One survives to return and spawn.The dangers are diving birds king fishers and bears. The needs are loose gravel cool clean oxygenated water. Article posted November 21, 2011 at 04:30 PM GMT0 • comment (5) • Reads 2725
