Finally, the selectivity for red shrimp of three different codend mesh configurations was measured and compared: In addition, fishing effort should be further reduced in years of intense DSWC events, to permit the recovery of the population.

The role of rostral shortening in the general behavioral pattern aristeu this species is discussed. Males of Aristeus antennatus exhibit marked shortening of the rostrum, which is long in juveniles and extremely short in adults. Finally, the mitigation of overfishing is also likely to increase the red shrimp population resilience to the effects of DSWC.

Oxford University Press is a department of the University of Oxford. Small males and females of all sizes display long rostra. Milne Edwards, Decapoda: Abstract Shortening of the rostrum in Aristeus antennatus in the Mediterranean Sea was studied by analyzing the relationship between rostral length and carapace length, taking the following factors into account: Shortening of the rostrum in males occurred at a definite time of year, between February and April of the first year of life in which sexual maturity is attained.

In the Catalan region, this species is fished along the continental margin of a system of submarine canyons and its landings present high inter-annual variability.

Both the yield per recruit analysis and the Statistical Catch at Age model showed that this resource is in overexploitation. In addition, the predicted equilibrium maximum sustainable yield MSY was considerably reduced in years of DSWC, indicating that only little harvest may be sustainable in years of adverse environmental conditions.

Including the effect of DSWC significantly improved the stock assessment model for this species. 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.
