Surface Temperature Influences the Population of Limnothrissa miodon in Lake Kariba

Global warming is a serious world problem where earth’s temperature has been reported to increase over the years; aquatic ecosystems are also not exceptions. But, effects of this phenomenon on well understood. This study aims understand influence surface population density Limnothrissa miodon in Lake Kariba. We constructed mathematical model dynamics with nutrients, phytoplankton, zooplankton, and Hydrocynus vittatus. water was modelled by cosine function, parameters were estimated from data fitting. Numerical simulations used determine stability nonautonomous model. simulation results showed stable periodic orbit for varying initial conditions, therefore, instability. techniques investigate miodon. Results fitted lake that shift optimal phytoplankton growth 25 ° C id="M2"> 34 C, corresponding dominance Cyanophyceae Chlorophyceae, resulted decline declines after an optimum id="M3"> 30 growth. suggested may lead
