Atlantic salmon is considered the “King of fish”, an appropriate title for many reasons. They made a spectacular journey in life, migrating from freshwater streams to the child when feeding in the North Atlantic and back when breeding. The ability to properly return the stream where they were born to create attention and confound the biologists in hundreds of years. Salmon in the most beautiful fish types; elongate silvery color, and graceful movement. They are also very powerful, in some of the most active species of fish in the world. More importantly, they are logos for the clean water, unpolluted are flowing out to sea. Those of us who live in the region near the Connecticut River, the Atlantic salmon is a sign of pure water and natural flow is being restored.
Atlantic salmon are about to reproduce will nest (known as redd) in the fall. They dig the hole in the bottom of the gravel of the stream by pushing them through the side and up and down by the body and tail. With the cheering of males, they lay their eggs in the nest. Eggs in the course of the winter and bloom in the spring. FRY hatch lived in gravel and continues to grow thanks to the energy reserves in the egg yolk and start feeding.
Atlantic salmon live in the first few years the small streams and rivers, eating the insects that live in the water and the plankton by water brought in sight of them. At this stage in our life is called “Parr” and the majority of them are solitary creatures to protect the territory of feeding with other fish can infiltrate and fight with them. After reaching the size approximately 4 inches (10 cm), this fish became “Smolt” in the spring and begin to move out of the ocean.
Southern New England where a long growing season, only take as long as two years to become a smolt, but farther to the North, the time will be longer: to three years in Northern Vermont, four years in Nova Scotia and five years in Newfoundland. In moving down the stream, smolt come on more integration, starting up and developing salinity tolerance that they need when on the ocean.
Once in the ocean, salmon takes advantage of and of hills food source grows rapidly. While the move to search for food, they go toward the main living areas in the North Atlantic Ocean near Greenland and Iceland. Once in the ocean, salmon had to Dodge several species of predatory creatures such as seals and the bigger fish to survive. After spending a year or two at sea, salmon begin the journey back. People think the salmon use the Sun or from the school to the direction to the coast of rivers where they were born, although this is not yet certain. then we use the sense of smell knows in the smolt stage to search the river and tributary of the river where they were born. Can salmon on fresh water in the spring, summer or fall, but spawning occurs in the fall, and a new life cycle.
Atlantic salmon was in trouble in New England for many years. Each has a very crowded, but the fish become extinct on the Connecticut River and Merrimac on the 1800 year because the construction of the hydroelectric dam has prevented them to reproduce. More recently, the salmon in the river downstream in Maine has experienced a decrease in the number of serious. It was thought that this reduction is partly due to the Professor reduced the number of salmon caused by worsening conditions of ocean related to temperature cycle. Because any old reason, salmon in Maine are currently classified as endangered. but also the hope of the Atlantic salmon. Twenty-five years ago, the federal Fisheries Agency and the State have concentrated effort to restore Atlantic salmon in southern New England. There are about 200 to 500 salmon have returned to the Connecticut River in each year of the last twenty years, although the participants are hoping the number of fish will increase. Last year, the natural salmon spawning in the first Massachusetts for more than 150 years has happened on the river tributaries of the Connecticut River, the Westfield. In the years to come, we can hope to see many of the “King of fish” back the water flow are recovering of the Connecticut River.
