Spawning stock biomass and fishing pressure for North Sea cod 1963-2002
Geographical coverage note: North Sea
Note: The black line corresponds to the precautionary spawning stock biomass (SSB) level of 150 000 tonnes and the precautionary Fishing pressure of F=0.65. F is an indicator of fishing mortality represented as a logarithmic function of catch per stock of given age groups (F 2-4 means fishing mortality of year classes 2 to 4-years old), F=10 is 100 %.
