The Impact of Dams on Insect Population

Although many individuals would say that extermination of bugs is nothing to frown and be sad about, it impacts the wildlife that thrives near the dam. Dams are nothing but a wall of concrete and asphalt holding back a torrential river and creating energy from its currents. The power and electricity that are derived from the river are known as hydropower. It is not only very common for dams to be constructed around the world but, it is also considered to be one of the cleanest and most reliable sources of renewable energy. However, this type of renewable energy cause significant damage to any wildlife surrounding it. A process known as hydrospeaking is caused by dams and is also considered to be extremely deadly to insects.

There are many types of fish that are always available in a dam. Some of the species available in a dam include multiple kinds of bass, cod, and trout, which makes visiting a dam for a fishing trip worthwhile. This is due to the build-up of fish, which is also due to the construction of a dam. Since there are many species of fish available in a dam, there is almost always wildlife around. This is the same for insects. Insects and bugs are a popular delicacy for surrounding creatures especially fish. Due to hydropeaking, there are lessening amounts of bug population available for the consumption of fish. This decline not only affects the quantity of fish available in a reservoir, but it also affects the speed in which pollination is achieved, as insects play a significant role in the pollination and spreading of new trees and plants.

Ever since the first dam ever built, there have been inventions created to make the dam more migration-friendly. But none of these inventions have done anything to help the cause and increase migration activity. There are many consequences to hydrospeaking. Bu tone of the most damaging and prominent issue is the usage of water. The release of water is documented to have increased over the years, which symbolizes a significant increase in the need and the production of electricity. Due to the changing needs in voltage, the banks of the river experiences heavy drying and rewetting along the shoreline. This poses as a significant issue as the shoreline of the river represents evidence of intertidal forces, forcing the river’s shore to resemble that of a beach.

Under careful examination and studies, scientists found that the process of hydrospeaking was hazardous to insects commonly found among the banks of the river. Some of the insects found in these areas include the mayfly, caddisfly and any other insect species that are a source of food to birds and fish alike. Scientist collected and placed the insects’ eggs under conditions that mimic that of hydrospeaking, and found that very few survived the ordeal. Insects are essential to the survival of fish and many other organisms. They are both a way of providing food and a way to spread eggs and other plants around. The decrease in insect population also means a massive decline in fish production and migration.
