Title Multispecies virtual population analysis
 
Creator Bharti, Vivekanand
 
Subject Analytical models
 
Description Fisheries are the major driver for the changing in properties of both fished and unfished
species, through direct and indirect effects. Direct effects can include reductions in population
abundance, age and size structure, biodiversity, community composition and habitat
destruction. Indirect effects, including incidental mortality, are transmitted through the
ecosystem by trophic interactions and competition, and may result in increased or decreased
abundance of prey or predator species, altering community composition. In recognition
of the complex, interconnected nature of marine ecosystems, ecosystem approaches have
been promoted as a way to improve fisheries assessment and management. There is a widerange
of multi-species and ecosystem modelling approaches. They range from extended
single species models to multi-species minimum realistic models, food web models to
whole ecosystem models with age and spatial structure. All models have their strengths
and weaknesses: simplicity may entail missing key processes, whereas complexity requires
more data, time and resources.
