  4. 3. Essays on the Infestation of Lake Victoria by the Water Hyacinth

    Författare :Eseza Kateregga; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Water hyacinth; water hyacinth indicators; water hyacinth induced catchability coefficients; intrinsic growth rates for stocks; carrying capacity; elasticity of catch with respect to fishing effort; electricity outage costs.;

    Sammanfattning : This thesis consists of four essays that seek to estimate the abundance of the water hyacinth in Lake Victoria during the 1990s and analyse its effects on the catchability of fish, estimate the elasticities of catch with respect to the various components of effort in lake Victoria fisheries, and estimate the welfare costs of electricity outages. In the first essay, data on the extent of water hyacinth mat coverage collected from a number of reports and surveys is used to fit time trend water hyacinth mats growth curves for the three sections of Lake Victoria.
