Aristeus antennatus – Wikipedia, la enciclopedia libre

Influence of predation by two crabs, Pachygrapsus marmoratus Fabricius, and Lophozozymus incisus H. Historical series of fishery data including fishing effort directed to the red shrimp were reconstructed from various data sources, and trends in the data series were analyzed. Stock status in the s and in recent afisteus was assessed using pseudo-cohort and yield per recruit analysis and compared. This could be achieved by decreasing fishing effort and fleet overcapacity, protecting the aggregations of juvenile individuals, and increasing the gear selectivity.

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.

This article is also available for rental through DeepDyve. 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.

According qristeus 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: This method allowed to include all the available data, covering a period of more than fifty years arisheus, as well as the effect of the DSWC. For this reason mature males with long, intermediate, and short rostra may coexist prior to the season of shortening.

Minimums in the historical series of yearly landings have been associated with antennatus occurrence of strong bottom currents generated by an oceanographic phenomenon named Dense Shelf Water Cascading DSWC.

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.

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

Males of Aristeus antennatus exhibit marked shortening of the rostrum, which is long in juveniles and extremely short in adults. 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: Sus desembarques presentan una elevada variabilidad interanual.

In fact, a drastic reduction of the red shrimp abundance in the fishing grounds of the Catalan area was observed during DSWC events.
