Report of the ICES/BSRP Workshop on Developing and Testing Environmentally-Sensitive Stock-Recruitment Relationships of Baltic Herring and Sprat Stocks (WKSSRB)
reportposted on 2008-01-01, 00:00 authored by ICESICES
The direct and indirect effects of climate‐induced hydrographic change and the effect of the parental stock on five Baltic herring stocks and Baltic sprat were investigated. Specifically, WKSSRB reviewed, updated and validated recruitment‐environment relationships developed by WKRPBH (ICES 2007b) for five distinct Baltic Sea herring stocks: the Western Baltic (WBH), the Main Basin (MBH), the Gulf of Riga (GRH), the Bothnian Sea (BSH) and the Bothnian Bay (BBH). The predictors to be included in the final recruitment models were selected on the basis of the parsimonious principle and the ecological criterion fulfilled simultaneously (ICES 2007b). Data were also up‐dated, including a revised time series of temperature, Baltic Sea Index and the inclu‐sion of the Bottom Depth Anomalies for sprat recruitment modelling.
