The role of rostral shortening in the general behavioral pattern of this species is discussed.

Influence of predation by two crabs, Pachygrapsus marmoratus Fabricius, and Lophozozymus incisus H. Finally, the selectivity for red shrimp of three different codend mesh configurations was measured and compared: Minimums in the historical series of yearly landings have been associated with the occurrence of strong bottom currents generated by an oceanographic phenomenon named Dense Shelf Water Cascading DSWC.
It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. This could be achieved by decreasing fishing effort and fleet overcapacity, protecting the aggregations of juvenile individuals, and increasing the gear selectivity.

This thesis contains a thorough assessment of the red shrimp fishery in Catalonia, with the main objective to provide management advice for the antennatuus exploitation of this resource.
Finally, the mitigation of overfishing is also likely to increase the red shrimp population resilience to the effects of DSWC. If you originally registered with a username please use that to sign in.

Rostral allometry is positive in females over their entire life span. A transition analysis to simulate the evolution of the yield per recruit and the biomass per recruit after a hypothetical implementation of the 50s in the fishery was performed. In particular, it was demonstrated that the DSWC significantly increases the red shrimps natural mortality.
