ABSTRACT The stocks of hake and sea bream in the northern part of the
CECAF area are heavily fished and the fisheries on them would benefit from
appropriate management measures. A minimum mesh size in trawls has been
recommended but appears not to be generally adopted. This paper examines the
practical problems (methods of mesh measurement, short-term falls in catches,
fishing on smaller species, methods of inspection, etc.) that need to be
considered if mesh regulations are to be effectively implemented and enforced.
Consideration is also given to the problems of reducing the total fishing
effort, whether uniformly over all fleets, or differentially. |
