Over a quarter of a century has now passed since ICES sponsored the highly influential symposium, Fish Stocks and Recruitment, in Aarhus Denmark in 1970. We seek to provide an overview of progress in understanding recruitment processes since this landmark meeting. The Symposium is dedicated to the memory of Professor R. J. H. Beverton, colleague, mentor, and friend to the ICES community.
Trophodynamics and Recruitment Success. We solicit contributions on the role of physical processes and hydrographic structures (e.g. turbulence, fronts, stratification) in relation to demographic rates and processes. Contributions which examine the importance of physical features relative to tradeoffs between growth and risk of predation are welcomed. We encourage contributions on the role of predation mortality in controlling year class success, field and laboratory studies of predation processes in marine systems, and the development of recruitment models incorporating predation effects.
Physical Transport, Retention, and Loss. Transport and dispersal mechanisms are hypothesized to have a profound influence on survival rates and population structure in the sea. We seek studies of the importance of retention and loss on early life stage dynamics. We encourage contributions on the role of mesoscale hydrographic features in recruitment processes including the specificity of spawning times and locations and transport to suitable nursery locations from spawning sites.
Climate Variability and Recruitment Processes. Documentation of causal factors underlying regime shifts in the marine environment is essential. Studies of synchrony in recruitment among different taxa or populations within species on large spatial scales have provided important insights into recruitment processes. We seek contributions which provide a broad-scale context for understanding recruitment variability and the implications of longer-term shifts in environmental conditions as a guide to possible effects of climate change on marine populations.
Population Regulation and Environmental Variability. The resilience of populations to exploitation is critically dependent on compensatory processes. Compensation can dampen the effects of environmentally-induced variability in recruitment. We seek contributions examining compensatory mechanisms at one or more life history stages, stock-recruitment models with environmental inputs, and analyses of interactions between environmental variability and internal regulatory mechanisms.
Life History Strategies in Variable Environments. Marine populations exhibit a diverse array of life history strategies in response to environmental variability. We encourage contributions examining fundamental life history characteristics in relation to recruitment processes. Examples of life history characteristics in relation to variable marine environments, comparative studies of life history traits across taxa, and the implications of different life history strategies in relation to anthropogenic perturbations.
