- Abstract
- An international bottom trawl survey (the Medits programme) is carried out
every year in the Mediterranean since 1994. During each survey, about 1000
hauls are done by a fleet of 8 to 9 vessels from 10 to 800 metres depth,
applying a unique standardized sampling protocol. This study analyses the
trajectory and the performances of the sampling gear used for this survey,
from records obtained during the surveys aboard some vessels in different
geographical sub-areas and at different depth levels. Two kinds of sensors
have been used, one to characterize a posteriori the vertical trajectory
of the trawl from the beginning of shooting to the end of hauling (830
hauls), the other to describe in real time the stabilization of the trawl
at its beginning (16 hauls) and its geometry during the tow (840 hauls).
The results show the variability extend of these parameters linked with
vessel, area, depth and period, illustrating their impact on the swept
area estimates used for biological assessments. They strongly suggested
the inforcement of a quality strategy combining the use of rigourous
sampling protocols and systematic controling of the main parameters
characterizing the trawl performance during routine surveys. (literal)
