Dynamics of phytoplankton communities in eutrophying tropical shrimp ponds affected by vibriosis.
Tropical shrimp aquaculture systems in New Caledonia regularly face major crises resulting from outbreaks of Vibrio infections. Ponds are highly dynamic and challenging environments and display a wide range of trophic conditions. In farms affected by vibriosis, phytoplankton biomass and composition are highly variable. These conditions may promote the development of harmful algae increasing shr...
متن کاملVibriosis in Shrimp Aquaculture
Aquaculture is the fastest growing food sector globally and is established itself as high protein resource to fulfill the food demand since the natural resources exhibits over exploitation. But, presently, the biggest problem faced by the aquaculture industry worldwide is diseases caused due to various biological and non-biological agents. Among the groups of microorganisms that cause serious l...
متن کاملInvestigation of species diversity and abundance of phytoplankton in shrimp culture ponds of Gomishan-southeast Caspian Sea
Abstract Beside knowledge on primary production and food webs, species composition and density of phytoplankton in shrimp culture ponds are an important issue in relation with shrimp diets and production in the ponds. In order to provide an updated information about phytoplankton community in shrimp culture ponds, this study was carried out to determine species composition and abundance of phy...
متن کاملEutrophication in a tropical pond: Understanding the bacterioplankton and phytoplankton dynamics during a vibriosis outbreak using flow cytometric analyses
In tropical shrimp ponds, the increasing of feed input, concomitantly with the stocking shrimp biomass, induces an eutrophication of the ecosystem. Although difficult to maintain, its stability is required to guarantee the success of the culture. A 110-day period of phytoplankton and bacterioplankton stock and dynamics in an earthen pond (1.2 ha area, 1 m depth) was monitored using flow cytomet...
متن کاملDynamics of phytoplankton communities under photoinhibition.
We analyzed a model of phytoplankton competition for light in a well-mixed water column. The model, proposed by Gerla et al. (Oikos 120:519-527, 2011), assumed inhibition of photosynthesis at high irradiance (photoinhibition). We described the global behavior through mathematical analyses, providing a general solution to the multi-species competition for light with photoinhibition. We classifie...
