Fish harder; catch more?
Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...

متن کاملIntrinsic vulnerability in the global fish catch
We have identified the marine fish taxa that are most vulnerable to exploitation, by compiling an index of intrinsic vulnerability based on life history traits. Since 1950, the global fish catch has been increasingly dominated by species with low intrinsic vulnerability, indicated by a decline in mean vulnerability of the taxa in the catches. This decline is strongest in catches of coral reef f...
