A line graph captioned 'Cod Catch and Biomass' with x-axis representing the 'Year' from 1950 to 2010 and y- axis representing 'Mass in metric tons' ranging from zero to 100000. Biomass is represented by red line & cod catch is represented by blue line. The graph indicates that cod catch has decreased significantly since the 1980s because of the sharp decrease of cod biomass in the ocean.
