Abstract:
The study was conducted from June, 2015 to October, 2016 to assess the effect of water hyacinth on fishing and fishers around the North-Eastern part of Lake Tana. The presence of water hyacinth in Lake Tana has been recognized in 2011. Starting from the last five years, especially after 2014, fishing in the study area becomes tiring due to the expansion of this invasive weed. Water hyacinth entangles the fishing nets and boats' propeller, making it difficult to fishing and resulting in reduced fish catches. A reduced fish catch would have an adverse effect on the quality of life of the communities around the lake and consequently affect sustainable development in the region. Despite the fact that several efforts have been made by different parties, water hyacinth in Lake Tana continues to flourish itself year after year. Therefore, once water hyacinth has appeared, its expansion is not easy to manage and complete eradication is unimaginable. If the expansion of water hyacinth continues in this trend, it can negatively affect the livelihood of fishers in both directions by increasing costs of fishing and reducing the amount of fish catch.
