International Council for the Exploration of the Sea, Palægade 2-4, 1261 København K, Denmark Causal correlation between recruitment and spawning stock size of central Baltic cod? [Elektronische Daten] [H. Sparholt] A biologically sensible model for cod recruitment in the central Baltic is proposed. The model takes into account, in a simple way, (1) the spawning stock size of cod, (2) the annual spawning conditions in terms of salinity and oxygen content, and (3) the predation on cod eggs by sprat. The parameters are estimated using regression analysis methods. All three factors are shown to be statistically significant, although sprat predation is the least clear effect. The model residuals are not correlated (no auto-correlation). The model is successfully evaluated against independent data. According to the model, cod recruitment at age 0 is proportional to the spawning stock biomass (SSB) for realistic ranges of SSB, for a given set of spawning condition and sprat predation. It is further shown that it is important to use recruitment data from an MSVPA, where cod cannibalism is included, in stock recruitment analysis of central Baltic cod. © 1996 International council for the Exploration of the Sea Articles nationallicence cod nationallicence stock-recruitment nationallicence MSVPA nationallicence cannibalism nationallicence auto-correlation nationallicence ICES Journal of Marine Science Oxford University Press 53/5(1996-10), 771-779 1054-3139 53:5<771 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0098 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0098 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Sparholt H.
