Helping Sturgeon Survive – Studies On Swimming Performance And Fishways Can Make A Contribution

Sturgeons (Acipenseridae) are primitive fishes that mature late and display migratory behavior. There are 25 species of sturgeon in the world and they have substantial value for both scientific and economic enterprises. However, for the past one hundred years, a rapid decline in sturgeon populations has been caused by human activities, including overfishing, pollution, and the proliferation of hydraulic structures, such as dams and other river works. Hydraulic structures interrupt river connectivity, obstruct sturgeon migrations, and change hydrologic variables in...

Helping Fish Move Freely: Study On Target Species And Swimming Ability, And How Fishways Can Help

Dams have expanded rapidly in the world. People focus on issues ranging from irrigation, hydroelectric power, water resource allocation, and ecological restoration and believe it will facilitate future operations. Although dams carry out enormous economic benefits and promote the development of society, they also influence the hydrological regime, water chemistry, and biological habitats, especially when it comes to river connectivity, often resulting in fragmentation. Dams obstruct fish from freely moving in rivers. Many fish species have migratory behavior. For examples, many...
