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: Including the effect of DSWC significantly improved the stock assessment model for this species. Grapsidae, Xanthidaeon intertidal mussels Mytiloidea in the Adriatic Sea.

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: 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.

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.

Sus desembarques presentan una elevada antennatua interanual.

Historical series of fishery data including fishing effort antenmatus to the red shrimp were reconstructed from various data sources, and trends in the data series were analyzed.

Email alerts New issue alert. 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: 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.

Males of Aristeus antennatus exhibit marked shortening aristfus the rostrum, which is long in juveniles and extremely short in adults. The role of rostral shortening in the general behavioral pattern of this species is discussed.

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

Finally, the selectivity for red shrimp of three different codend mesh configurations was measured and compared: You do not currently have access to this article. 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.

In fact, a drastic reduction of the red shrimp abundance in the fishing grounds of the Catalan area was observed during DSWC events. You could not be signed in. Small males and females of all sizes display long rostra. 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.

Grooming behaviors and setal morphology in smasher and spearer mantis shrimps Stomatopoda. This could be achieved by decreasing fishing effort and fleet overcapacity, protecting the aggregations of juvenile individuals, and increasing the gear selectivity.

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. This item is licensed under a Creative Commons License.

qristeus Both the yield per recruit analysis and the Statistical Catch at Age model showed that this resource is in overexploitation. Finally, the mitigation of overfishing is also likely to increase the red shrimp population resilience to the effects of DSWC.

In addition, fishing effort should be further reduced in years of intense DSWC events, to permit the recovery of the population.

Rostral allometry is positive in females over their entire life span.
