“…P. narval presented a CL distribution pattern per sex characterized by the predominance of males in the lower classes and females in the higher, showing that females had a mean size significantly higher than males. The same pattern was described for this species in Canary Islands (Lozano et al, 1990;González et al, 1997) and for other pandalid species such Plesionika heterocarpus (A. Costa, 1871) (Company and Sardà, 2000), Plesionika martia (A. Milne-Edwards, 1883) (Company and Sardà, 2000;Maiorano et al, 2002), P. edwardsii, Plesionika gigliolli (Senna, 1902) and Plesionika acanthonotus (Smith, 1882) (Company and Sardà, 2000) in Mediterranean and P. edwardsii (Lozano et al, 1990) and Heterocarpus ensifer A. Milne-Edwards, 1881 (Tuset et al, 2009) in the Canary Islands. These gender differences may be related to morphological development of each sex, with the differential investment in reproduction between the sexes and the energy available in the habitat where they are distributed (King, 1995).…”

“…Ovigerous females showed a trend of seasonal migration with depth in the archipelago of Madeira. These trends are common in pandalids and were reported to the Canaries (González et al, 1997) and Mediterranean (Thessalou-Legaki, 1992) for this species and for P. martia (Maiorano et al, 2002) and P. edwardsii (García-Rodríguez et al, 2000) in the Mediterranean.…”

Analysis of abundance and population structure of Plesionika narval was performed on data concerning 5,255 specimens obtained from 62 fishing sets carried out off the Madeira archipelago (Northeastern Atlantic) between 2004 and 2008 in a depth range from 101 to 350 m. Abundance ranged from 0.01 to 19.74 specimens-per-trap and significant differences were found between seasons, probably as a result of an increment of population in the spring during the recruitment season. The analysis of size distribution revealed that the carapace length (CL) ranged from 2.45 to 28.61 mm and that mean female size consistently exceeded that of males. Differences in mean CL were statistically significant between depth strata and seasons. Of the specimens sampled, 57.00% were males, 41.88% females and 1.42% undetermined. Sex ratio also differed significantly between seasons according to depth strata, consolidating the hypothesis of the existence of seasonal migrations related with the reproductive cycle of this species. Ovigerous females showed larger sizes and occurred all year around and remain in shallow waters in winter, summer and autumn and move to deeper waters in spring. The highest frequency of ovigerous females was recorded in summer, between 151 and 200 m deep supporting the hypothesis that spawning of this species occurs in shallow waters, especially in late summer.

“…The WLR is a practical condition index and may vary temporally according to factors such as food availability, feeding rate and reproductive activity, however the b parameter usually does not vary significantly throughout the year (Bagenal and Tesch, 1978), and together with a (condition factor) can be considered mean annual values, as suggested by several authors (Santos et al, 2002;Andreu-Soler et al, 2006). The results indicate a strong pattern of negative allometric growth in the studied species of nektobenthic shrimps off the coast of Madeira which is in accordance with previous studies for pandalid shrimps P. edwardsii, Plesionika antigai Zariquiey Álvarez, 1955, Plesionika gigliolii (Senna, 1902, P. narval, Plesionika heterocarpus (A. Costa, 1871) and P. martia (Martins and Hargreaves, 1991;González et al, 1997González et al, , 2016Company and Sardà, 2000;Maiorano et al, 2002;Thessalou-Legaki et al, 2005;Vafidis et al, 2008;Sousa et al, 2014). The same pattern is also well known for Aristaemorpha foliacea (Risso, 1827) (Ragonese et al, 1997), Aristeus antennatus (Risso, 1816) (Carbonell et al, 1999 and Heterocarpus laevigatus (Dailey and Ralston, 1986).…”

Length and weight relationships and descriptive statistics are reported for six shrimp species caught off the Madeira archipelago between 1983 and 2014 using bottom and floating traps from depths ranging from 50 to 1,300 m. The parameter b ranged between 2.36 for Plesionika ensis and 2.97 for Plesionika williamsi. All species showed a pattern of negative allometric growth. To the authors' knowledge all weight-length relationships presented herein are recorded for the first time from the Madeira area, and in the cases of Ligur ensiferus and Plesionika ensis are the first references worldwide.

“…Similarly, the Bathyal Demersal Group was mainly represented by demersal and benthodemersal fauna, with only 2 stenotopic species: Caelorhynchus caelorhynchus and the juveniles of Aristaemorpha foliacea, which are characterized by feeding habits linked to infaunal and epibenthic prey (Ma durell & Cartes 2006, Kapiris et al 2010. Nezumia sclerorhynchus, Hymenocephalus italicus, Galeus melastomus, Hoplostetus mediterraneus and Plesionka martia represent the main indicator species in the group, exhibiting a eurytopic habitus, likely to be due to their feeding behaviour: G. melastomus is a generalist predator of epibenthic and benthopelagic species (Carrassón et al 1992), H. mediterraneus feeds on suprabenthic and benthopelagic prey (Madurell & Cartes 2005), and P. martia is an active predator on macrozooplankton and benthic resour ces (Cartes 1993), with a population in the NW Ionian Sea structured in an ontogenetic pattern and depth distribution as reported by Maiorano et al (2002). Similarly, N. sclerorhynchus and H. italicus were grouped with eurytopic species, exhibiting pelagic and suprabenthic diets (Madurell & Cartes 2006).…”

An exploration of the structure of demersal and benthopelagic assemblages in the northwestern Ionian Sea was carried out by means of a set of statistical analyses. Self-organising map (SOM) and clustering methods applied to 183 taxa and their biomass (kg km −2) provided the classification of 1288 experimental hauls exploring the bathymetric range 10−800 m from 1995 to 2012. Six clusters were identified according to their similarities in species abundances (biomass), confirming the depth gradient as the main structuring agent. In order to identify key representative species in each cluster, the taxa were ranked by means of an indicator value index (IndVal) and the contribution of species to beta diversity (BD). Furthermore, the clusters were described by means of environmental and fishing characteristics. Particular habitat type, distance to canyon and fishing effort segregated the assemblages on the coastal shelf and slope. Temporal differences were detected in 2 bathyal groups, which were most likely affected by the 1990s environmental change in the deepwater circulation known as the Eastern Mediterranean Transient. The overall total BD in the study area was calculated as 0.79, with a temporal decrease observed at a rate of 0.7% yr −1. The approaches used are useful to identify and characterize the species aggregations inside complex faunal assemblages, without a priori assumptions about data distribution. These results can be a starting point for defining functional groups for Mediterranean food web modelling approaches, as well as for identifying indicator species to assess the environmental status in the context of the Marine Strategy Framework Directive.
