Disadvantages Of Salmon Ladders

There are many environmental issues to talk about. Choosing one was a difficult task, but I choose this problem because is it close to home. I also choose this topic because it effects a lot of ecosystems and it has an impact on humans too. It is crucial to the environment that this problem gets fixed. There are a few solutions I will talk about that try to help with the problem I choose. Of the three solutions, there is one that I think will work the best. I will also show you the advantages and disadvantages of the different solutions. Just like any other topic, there are a lot of different opinions about the solutions and why there are good or bad. This is why I will also discuss what my opinions are about them. I hope you find my topic …show more content…
One of the advantages of the salmon ladders is that it allows the salmon to be able to get to parts of the river they wouldn’t have had gotten to otherwise. Another advantage to the salmon ladders is that scientists can use them to judge how strong the salmon numbers are for a particular breed during a certain time of year. A disadvantage to salmon ladders is that sometimes they are only designed for certain breeds of salmon. Another disadvantage to the salmon ladders is that they only work for the adult salmon to go though. Some salmon ladders are not designed for steelhead and juvenile salmon, which means those fish will have to be transported across the dam. A disadvantage to transporting them across the dam is that it could mean the salmon are being delayed from spawning up river. An additional disadvantage of the salmon ladders is that it doesn’t help juvenile’s, so they have to go through the process of going through churning turbines or they have to go through the spillway gates on the dams. The gates can be a really big drop, like on the Detroit dam in Oregon. There is also the disadvantage of disease spreading to fish that get put into tanks on the boats and trucks. This can cause the problem to get worse when it comes to the number of …show more content…
An advantage to this plan is that can add a lot of salmon back into the environment. Another advantage to this program is that it helps to support the local fishing market. A third advantage of this program is that it lets wild salmon live in oceans without being fished to extinction, because the only salmon that you are allowed to keep are the fish hatchery salmon. An advantage of this method is that it means they won’t ever be totally whipped out because they would be able to put some salmon back into the ecosystem. This can be a positive thing to increase salmon numbers, in case the other solutions fail. In addition, some of the fish hatchery salmon are tagged so that fish and game scientists can study the information collected from the journey of the salmon. Another advantage of this plan is that it gives the salmon a safe place to be so they can spawn and not have to worry about that ecosystem getting demolished by people. A disadvantage to this solution is that “Scientists know that hatchery fish that interact with wild fish can pose genetic and ecological risks to wild salmon recovery, such as increased competition and reduced fitness--the ability of a fish to survive and reproduce.” (Ford, 2014). A disadvantage of this is that it can affect generations of salmon, whether they are wild ones or bred in captivity. There is another disadvantage of this plan,
