Risks and Benefits of stocking lakes with fish

#2
Stocking lakes with fish can develop both positive and negative factors. There are many obvious, and some not so obvious risks involved. However; there can be many benefits of stocking lakes with fish as well.
The first risk of stocking lakes with fish is that the population could be so large in one area that it could result to overcrowding. Overcrowding can lead to many negative factors. For instance: in the 18th century when the Industrial Revolution evolved, the city populations expanded greatly which caused a sufficient amount of crime rate and disease. This can occur with the fish as well. The diseases that can occur are most likely the biggest risk of stocking fish. When there are more species in one area it is easier to pass on diseases. In severe cases, disease has the power to wipe out a species, or at least the species in that area. Another large risk is the food resource that is available. If there is a large amount of fish in one area, then the food will less abundant more and more after each meal. This can also lead to diseases as they won’t be able to get a sufficient amount of nutrition. If there is too many fish in one area, there might not be enough room for them all to live in that environment. This can result in habitats getting ruined as they try to fixate new places to live within the area, or fish might migrate far away to find a home, which would defeat the purpose of stocking an area if they’re going to go elsewhere anyways.
By stocking fish in lakes, there can be many benefits as well. The biggest benefit of stocking is that it can repopulate lakes where the previous fish have been removed. It will save the fish population by allowing various fish species to be together and create offspring’s. Stocking fish where the number is poor can also prevent from extinction. Allowing one type of fish to be stocked into an area with another type of fish can lead to the possibility of creating a new fish. This can benefit the fish environment by creating more to the food chain and environment. Stocking fish in an area can be beneficial to the public too as it allows a great fishing opportunity. Not only will there be an abundant amount of fish, but there will be a wide variety of fish species to catch as well. This can benefit restaurants as they can catch the fresh fish they need to offer on the menu.
In conclusion, there are various risks and benefits that can occur from stocking lakes, or any body of water, with fish.

  1. I agree with this post that there are many positive and negative impacts from stocking lakes with fish. I like the example that was used, i thought it went very well with the topic and helped give a more detailed example. I never realized that stocking the lakes could cause overcrowding and end up killing off a species but that it could also help to save a species as well. This would be an interesting discussion topic because there are so many different sides to it. Overall, i agree that there can be many risks and benefits in doing this and i also learned a few new things from this blog.
