22.3.4 Northern Alboran Sea Fleet Evolution
Northern Alboran Sea fleet time series are even more problematic and more difficult
to produce than capture series. The first time series of fleet and fishing gear began in
1940 even if other partial data was registered prior to this year. This information was
attached to the publication of annual fishing statistics Estadísticas Pesqueras done
by Spanish government for period 1940–1970. Nonetheless, this statistics suffer
from important errors given that they do not provide the detail of the fishing gear of
vessels but only the typology of propulsion. Moreover, this information refers to the
port where boats are registered, and it does not necessarily coincide with the port
where they are dispatched when vessels are moving at sea.
The Spanish government began to publish annual statistics of fleet census per
fishing gear in La Flota Pesquera Española for vessels over 20 GRT in period
1965–1972. These statistics also provided a summary of vessels smaller than
20 GRT. Anuario de Pesca Marítima substituted the latter publication for the period
1973–1986. This statistical source publishes aggregated data per GRT and fishing
gear in Spanish territorial waters fishing districts. Spanish fishing fleet register was
first published in 1989. Since then, it is possible to build non-aggregated time series
of the fleet per port.
