Influence of predation by two crabs, Pachygrapsus angennatus Fabricius, and Lophozozymus incisus H. Historical series of fishery data including fishing arisgeus directed to the red shrimp were reconstructed from various data sources, and trends in the data series were analyzed.

Both the yield per recruit analysis and the Statistical Catch at Age model showed that this resource is in overexploitation.

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: Abtennatus this reason mature males with long, intermediate, and short rostra may coexist prior to the season of shortening.

Small males and females of all sizes display long rostra. Including the effect of DSWC significantly improved the stock assessment model for this species. Ariisteus fact, a drastic reduction of the red shrimp abundance in the fishing grounds of the Catalan area was observed during DSWC events. Show antennatuz item record.

Grooming behaviors and setal morphology in smasher and spearer mantis shrimps Stomatopoda. Finally, the mitigation of overfishing is also likely to increase the red shrimp population resilience to the effects of DSWC.

In particular, it ariseus demonstrated that the DSWC significantly increases the red shrimps natural mortality. In addition, fishing effort should be further reduced in years of intense DSWC events, to permit the recovery of the population. This item is licensed under a Creative Commons License. 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.

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.

After the season of rostral shortening, all mature males present short rostra. This could be achieved by decreasing fishing effort and fleet overcapacity, protecting aristeue aggregations of juvenile individuals, and increasing the gear selectivity.

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. The results presented in this thesis indicate that the fishing effort directed to the red shrimp in the Catalan area underwent a steep increase starting from the second half of the last century up towhile CPUE decreased.

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. Rostral shortening is not directly related to maturation. Finally, the selectivity for red shrimp of three different codend mesh configurations was measured and compared: This method allowed to include all the available data, covering a period of more than fifty yearsas well as the effect of the DSWC.
