“…This finding clearly showed that in both species, but particularly in P. sivado, juveniles had a wider thermohaline window, indicating they are able to cope with a wider variability in temperature and salinity conditions. A close dependence on a restricted salinity range has also been shown in deep-sea and continental slope crustaceans, such as Parapenaeus antennatus and Aristeus antennatus (Guijarro et al 2008(Guijarro et al , 2009, while species displacements related to movements of water masses have also been found to occur at wide temporal and geographical scales (Cartes et al 2009(Cartes et al , 2011, linked to relatively small density changes in seawater masses.…”

“…Mean density and biomass values were calculated by averaging the obtained density values over the total number of hauls made within each combination of geographic sector and depth interval, including zero values. For both species, and for the whole study area, one-way analysis of variance was used to test for significant interannual differences in density (natural logarithmic transformation), after testing for normality of data and homogeneity of variances (Guijarro et al 2008(Guijarro et al , 2009. If no significant interannual differences were detected, a two-way ANOVA was then used considering geographical sectors and 100-m depth strata as factors to test for significant differences.…”

This work aimed to analyse the main characteristics of the bathymetric and geographic distribution, population size structure and size at maturity of the continental slope caridean shrimps Pasiphaea sivado and Pasiphaea multidentata in the western Mediterranean, as well as to try to relate the patterns obtained with geomorphologic and hydrographic characteristics. The study area encompassed the Mediterranean coast of the Iberian Peninsula. In both species, marked differences in depth distribution, density, and population size structure were found between Algerian basin populations, particularly in the Alboran Sea, and those in the Catalano-Balearic basin. Both shrimps showed a shallower bathymetric range in the westernmost region of the Algerian basin than in the rest of geographic sectors, linked to the occurrence of upwelling areas on the northwestern edges of the Alboran Sea. Populations of P. sivado reached larger densities, sizes and maturity size in the Algerian basin. No recruitment of P. multidentata was detected in the Algerian basin, whereas it was present in the Catalano-Balearic basin. In both species, the window range of bottom temperature and salinity was larger in juveniles than in adults. These different distribution and population dynamics imply that ecological functioning of these species differs between the two geomorphological basins of the western Mediterranean Sea.

“…Mature females are present throughout the year (Levi et al 1995), so the species shows a continuous recruitment pattern (Sobrino et al 2005). A large number of fleets target the species, particularly in the eastern Mediterranean (Politou et al 2008), but it is also exploited in the eastern Atlantic (Benchoucha et al 2008), the Balearic Islands (Guijarro et al 2009) and the Tyrrhenian Sea (Sbrana et al 2006, Milisenda et al 2017.…”

The main characteristics concerning the distribution of two of the most important decapod crustaceans of commercial interest in the Mediterranean Sea, the deep-water rose shrimp, Parapenaeus longirostris, and the Norway lobster, Nephrops norvegicus, are studied in the European Mediterranean waters. The study is based on data collected under the MEDITS trawl surveys from 1994 to 2015 from the Gibraltar Straits to the northeastern Levantine Basin (Cyprus waters). The observed differences can be interpreted as different responses to environmental drivers related to the differing life history traits of the two species. In fact, N. norvegicus is a long-living, benthic burrowing species with low growth and mortality rates, while P. longirostris is an epibenthic, short-living species characterized by higher rates of growth and mortality.

“…That necessitates being well versed in the conditions under which the catches are made and, in particular, the possible effects of discards when landing based abundance indices are considered. For some species, discards can be assumed to be virtually absent (Guijarro et al, 2009;Sbrana et al, 2006). For others it is not the case (Lorance and Dupouy, 2001); discarding of marketable fish may bias CPUE (Quirijns et al, 2008).…”

“…We detected clear changes in the trend of landings per fishing trip in 2005 for trawlers and netters. Discussions with professional fishermen and their representatives associated with this work enabled these observations to be linked to the implementation of a selectivity device confirmed later by the Council Regulation (EC) (No 1288(No /2009. To overcome this regulatory bias, we focused the analysis on the 2005-2015 period.…”

For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and causes' prioritization; (ii) cluster definition to obtain a typology of vessels; (iii) average LPUE per cluster analysis; (iv) consideration of gear mesh classes and seasonal variations (quarters). This approach is outlined for the Striped red mullet of the Bay of Biscay that is currently in DLS category 5. Two reference fleets are thereby proposed: firstly the otter trawlers composed of small vessels (7.9-15.8 m) with a gauge of 2-43.9 grt, an engine power between 44 and 256 kW and a gear mesh of 70-79 mm; secondly the set gillnetters, which are defined by medium-sized vessels (8.2-14.8 m, 2-30.2 grt, 70-331 kW) whose gear mesh is either 50-59 mm (2nd and 3rd quarters), 60-69 mm (2nd quarter) or greater than 90 mm (2nd quarter). LPUEs of these fleets show a downward trend, significant in two out of four cases which may reflect a deterioration of the status of the Striped red mullet stock. Highlights ► Data-filtering method maximizing usefulness of biological, catch, regulation data. ► Fishermen involvement to assess impact of regulation changes on indicators. ► Potential high bias induced by discards when using LPUE as proxy of abundance. ► For Striped red mullet, decreasing tendency of LPUEs over the study period.
