In the first stage it is called fry.
. Fry grows there for approximately 4 years and becomes smolt. Firstly salmon start their life cycle by adult salmon spawning and then eggs are incubated for a while. Next smolt swims into open ocean where it lives for 5 years and finally becomes adult salmon.
We can see that the life cycle of salmon is consist of 8 stagesamong which salmon migrant place to place for growthFrom very beginningthe adult lying eggs in the riverthen the eggs would develop into emergence form and then travel to freshwater area to growthWhen their figure get more biggerthey will migrant to estuary area continuing growth. To start with the. The egg stage the fry stage the smolt stage and the adult stage.
Model Answer 1 The given diagram explains the life cycle of a Salmon which is a fish that is native to the North Atlantic and the Pacific Ocean. However the entire process travels from the river to the ocean with various cycles whereas each process is common in all kinds of salmon fishes. In addition salmon travel to the river estuary ocean and return to their place of birth.
Overall there are eight stages in the life cycle of the salmon starting with eggs and continuing until they become fully-grown adults. At the beginning of the life cycle eggs are laid and incubated in rivers. Overall it is apparent that the phase initiated from the incubation stage to freshwater rearing in the river.
Here are the life of salmon fish all 3 step start to the upper river and at the open sea. They have stages named fry smolt and adult salmon. It is apparent from the diagram that the life cycle of this fish is an ongoing process and there are six stages in total.
Overall a salmon fish goes through six main phases to fully grow from their hatching period and they spend their lives in three distinct locations river estuary and ocean. The next one estuary is a transition part between river and ocean and salmon continue their growing here as well. IELTS Report 3 on the lifecycle of Salmon Introduction The given life cycle belongs to a large fish called salmon.
Detail 1 To begin with the adult salmon lay eggs upriver where the current is slow. The process diagram illustrates the life cycle of salmon fish from egg to adult fish. Firstly adult salmon return to the upper river to lay an egg under the small stones and reeds approximate 5 or 6 month for the little fish appear begin the cycle life as they parent use to have.
After initially hatching in a slow moving river each Salmon spends roughly equal amounts of its 10 year cycle in fast flowing freshwater and open seas. It is noticeable that the life cycle of the salmon experiences three main stages spawning rearing and growth and they live in three different locations including rivers estuaries and oceans where are related to salmon development. The diagram depicts the life cycle of salmon fish dividing it into different stages from its egg stage till adulthood.
For approximately 5 years into an adult salmon which they could grow around 70-76 cm long. Firstly the egg is laid by the adult salmon which hatches in about 3 months. The information leaves us with three stages of the salmon life cycle.
Egg fry smolt and adult. The small fish is found in lower rivers then it migrates into the sea after it is fully developed. After incubation from these eggs baby salmon emerge and this step is followed by freshwater rearing where salmon get bigger.
After 4 year they move to the lower river where is fast. In the second stage it becomes a smolt which is followed by the last stage where an adult salmon is formed. Overall the life cycle consists of 3 stages.
The red part is correct. Overall it goes through four different stages of development. The picture clearly shows that the life cycle of this special type of tuna fish initiates in deep water with mating between male and female species which are sexually mature in the Nekton period.
Overall salmon have an average lifespan of 9 years and their life cycle consists of four main stages. The whole process from egg turning into a spawning adult takes place in 7 stages. As you can see.
Overall a salmon fish goes through six main phases to fully grow from their hatching period and they spend their lives in three distinct locations river estuary and ocean. After fully growing up adult salmon goes back to upper river to lay eggs and thus cycle repeats itself. Salmon has 3 main states of life.
Overall there are three stages in its life process. You can understand it this way. By these diagrams we could conclude how salmon life cycle happen and we could keep on feasting their tender meat.
Write at least 150 words. The diagram represents salmons life cycle. The diagram depicts the life cycle of salmon fish dividing it into different stages from its egg stage till adulthood.
Eggs embryos fry smolt and the adult fish. Firstly the salmon lays eggs among minute pebbles which change into reeds after approximately five to six months and are mostly found in very slow paced rivers. At the first stage in the life cycle the female salmon chooses the best spot in rivers and lays a massive number of eggs which are then incubated before developing into tiny fish.
Write at least 150 words. It is clear that there are six major steps in the development process of salmon beginning as eggs and ending as mature adults. The diagrams illustrate the different stages of a large fish known as the salmon.
Finally the adult salmon will find a mate and lay salmon eggs by the upper river.
