This article analyzes the effects of the invasion of water hyacinth on fishing in Lake Victoria.

This study of the deleterious effect on fishing by the water hyacinth invasion of Lake Victoria found an unusual positive: the decline of fish catchability caused by the the abundance of water hyacinths has paradoxically stopped or at least postponed serious overfishing.

The yellow floating heart is a water weed causing nuisance problems in Swedish watercourses. An economic analysis of this is required where various management options are considered.

The purpose of this paper is to create and discuss a measure of water hyacinth abundance in Lake Victoria. Water hyacinths have dramatic effects on other activities such as fisheries. However, understanding their spread and effects is hampered by the lack of reliable information.
