Stock status in the s and in recent years was assessed using pseudo-cohort and yield per recruit analysis and compared.

In particular, the SCAA was used to test alternate hypotheses on the mechanisms of interaction between the DSWC and the red shrimp population and to estimate reference points for management.

This thesis contains a thorough assessment of the red shrimp fishery in Catalonia, with the main objective to provide management advice for the sustainable exploitation of this resource. Citing articles via Google Scholar. 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.
Finally, the selectivity for red shrimp of three different codend mesh configurations was measured and compared: Grapsidae, Xanthidaeon intertidal mussels Mytiloidea in the Adriatic Sea. Company Claret, Joan Baptista.
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. Small males and females of all sizes display long rostra. 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.
Grooming behaviors and setal morphology in smasher and spearer mantis shrimps Stomatopoda. For this reason mature males with long, intermediate, and short rostra may coexist prior to the season of shortening.
Rostral shortening is not directly related to maturation. Milne Edwards, Decapoda: The role of rostral shortening in the general behavioral pattern of this species is discussed. This article is also available for rental through DeepDyve.
Sus desembarques presentan una elevada variabilidad interanual. Most users should sign in with their email address. This could be achieved by decreasing fishing effort and fleet arsteus, protecting the aggregations of juvenile individuals, and increasing the gear selectivity.
The average discard ratio found in this study 0. Rostral allometry is positive in females over their entire life span.

In addition, fishing effort should be further reduced in years of intense DSWC events, to permit the recovery of the population.
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.
Including the effect of DSWC significantly improved the stock assessment model for this species.

This method allowed to include all the available data, covering a period of more than fifty yearsas well as the effect of the DSWC.
In particular, it was demonstrated that the DSWC significantly increases the red shrimps natural mortality.

Finally, the mitigation of overfishing is also likely to increase the red shrimp population resilience to the effects of DSWC.

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. Email alerts New issue alert. In addition, the predicted equilibrium maximum sustainable yield MSY was considerably reduced in years of DSWC, indicating that only little harvest ariisteus be sustainable in years of adverse environmental conditions.
According to the results of this thesis, a fishery management aiming at the long term sustainable and profitable exploitation of the red shrimp should include measures to:
