Landings per tonnage in the Northern Alboran Sea have decreased during the
whole period (from 8.7 T/GRT in 1941 to 2.9 T/GRT in 1976 and 1.7 T/GRT in
2018). In contrast, the decrease in monetary terms has been smaller (56%) partly
alleviated by a price increase (a 118% price increase since 1941 due to the reduction
of supply) in contrast with an 80% reduction in physical terms.
