New Approaches to Mesozooplankton Production Estimates against the Background of Food Web Considerations for the Bornholm Basin (Southern Baltic Proper)
Authors:Karl Dahmen
Abstract:Mesozooplankton production was estimated by using a new sampling technique and two alternative calculation methods. In essence, production estimates are based on significantly higher abundances. The contribution of juvenile stages to copepod and fish dynamics was generally low, so that the omission of juvenile stages in budgets will result in a small error. The situations reported in this study present a unique food web szenario, which in detail, however, was strongly dependent on methodology. Furthermore, relations between trophic levels were considered with respect to vertical distribution.
