Helping Migration of Fish

Using Laser Lights to Help Migrations of Fish

How use of directional lights to help move fish migration to have them thrive. Could the use directional of lights during a fish migration impact the amount of population that will survive?

Problem Statement

Starting to plan to help the future of salmon runs and potentially save the economy of Washington by use of directional lights to lead them.

Significance and Value of Study

The significance of this research is to protect the ecosystem of Washington and it's fish economy and community fishing seasons.

Hypothesis and Assumptions

The idea is that the light could used to attract the fish to a hatchere to help keep the numbers up to have better runs. Also you the light to possibly help with other large marine species migrations.

Proposed Method of Study

My proposed method of study is to use experimental method.

Definitions and Variables

Time: Time is going to be used for how long it takes for the fish I am using to follow and make their way through the tunnel.

fish that follow: I am tracking how many fish out of a school will follow the light I am using.

color/type of light: I will want to write down color to see if a type effects the followers and time and see if it affects the group.

type of fish: I want to track my fish I am using so I have differing types and can see different results from the types if any. I will not be using salmon or trout unless I can obtain them legally and useable.

Results/findings

The results from the experiment show that there was movement of the fish with the addition of a new pond addition and this shows that 23 was the total amount of crossovers to the pond. Their were most commonly 1 cross overs a day but there were fish did not move from either the original pond or new one with occasional 2 and 3 crossing over in a day.

Implications - so what?

The implications of this research are that it is to save the loss of salmon over the years in the pacific Northwest. Also, by maintaining the balance of preservation and keeping fish for anglers to catch. Which will lead to a safe and effective way to save dwindling salmon species and potentially saving other species.

Conclusion (assumptions/hypothesis changed, confirmed, refuted?)

The conclusion from the data and failures of this experiment it disproves the hypothesis of the light impacting the movement of fish, but leaves the question and experiment open to be expanded to new areas and large scale. Which also refuted my assumptions made earlier.

Next steps

The next step for this research would be to have it be taken up again and tested in a more effective environment. Also, potentially using the research to help other marine species other than salmon specifically.
