Fig 1.
Effect of increased CO2 on early life survival of Gadus morhua from (a) Barents Sea cod (b) Western Baltic cod.
Each symbol represents the value of one replicate tank. Lines depict the number of survivors according to the fitted negative exponential function.
Fig 2.
Recruitment functions under baseline and under ocean acidification scenarios for (a) the Barents Sea cod and (b) the Baltic Sea cod.
The baseline scenario is based on no OA and spawning stock biomass at ICES precautionary biomass levels (BPA) in dependence of the duration of OA-induced mortality. For better visualization a different scaling on the second y-axes was chosen for the impacted recruitment.
Fig 3.
Population recruitment under ocean acidification (OA) for Western Baltic cod (black line and symbols) and Barents Sea cod (grey line and symbols).
Recruitment is given relative to a baseline scenario of no OA and spawning stock biomass at ICES precautionary biomass levels (BPA) in dependence of the duration of OA-induced mortality. Two important points in larval development are highlighted. Standard deviations displayed only for selected days to improve readability.
