Results on main elasmobranch species captured during the 2001-2009 Porcupine Bank (NE Atlantic) bottom trawl surveys

This paper presents the results on nine of the most important elasmobranch fish species of the nine years (2001-2009) of the Porcupine bank Spanish surveys. The main species in biomass terms in Porcupine bank bottom trawl survey, in decreasing biomass abundance order, are: blackmouth catshark, birdbeak dogfish, velvet belly, Knifetooth dogfish, lesser spotted dogfish, bluntnose sixgill shark, sandy ray, cuckoo ray and common skate. Many of these species occupy mainly the deep areas covered in the survey, especially birdbeak dogfish, knifetooth dogfish and velvet belly. Less confined to deeper grounds are blackmouth catshark and sandy ray, while lesser spotted dogfish and cuckoo ray inhabit mainly the shallower grounds close to the Irish shelf or the central mound in the bank. Length distributions of these species along the survey series are also presented and discussed. The few available data on siki sharks from the Porcupine bank survey are also summarized.Versión del edito

Results on Argentine (Argentina spp.), Bluemouth (Helicolenus dactylopterus), Greater forkbeard (Phycis blennoides) and Spanish ling (Molva macrophthalma) from 2012 Porcupine Bank (NE Atlantic) survey

This paper presents the results on four of the mostimportant deep fish species of the last Porcupine Spanish survey carried in 2012, and updates the documents presented in previous years with the information on the eleven years (2001-2011) of the Porcupine Spanish bottom trawl surveys on the Porcupine Bank. The document presents total abundances in weight, length frequencies and geographical distributions for Argentina spp. (mostly A. silus, results on proportions by Argentina species distribution in last surveys are provided),bluemouth, greater fork-beard and Spanish ling. All species considered present increases in their abundances, that are especially remarkable in the case of greater forkbeard and Spanish ling, confirming the good recruitments detected in 2011 survey. Besides both species have shown new recruitment peaks in 2012 survey.Versión de edito

Las políticas de responsabilidad social corporativa para la inclusión de las personas con discapacidad como predictores de identificación, compromiso y absentismo de los empleados

Few studies have explored the effect on employees of corporate social responsibility (CSR) policies focused on the inclusion of people with disabilities. The present research examines the extent to which employees’ perceptions of CSR policies aimed at the employment of disabled people are related to organizational identification, commitment, and absenteeism. A questionnaire was administered to 104 employees (participation rate: 41.1%). Correlations and common method variance tests, and linear regressions were performed. Only the internal-focus policies have an effect on employees’ identification and commitment, although the external-focus policies have been more deeply studied. There were no significant results related to absenteeism. Our research highlights the impact of internal-focus policies for the inclusion of people with disabilities in the commitment and identification of all employees, those with and without disabilities. The results also contribute significantly to the design of strategies that facilitate and enhance the normalization of these employees in the labor market, helping practitioners to target these companies as future employers of people with disabilities.Pocos estudios han analizado el efecto en los empleados de las políticas de Responsabilidad Social Corporativa (RSC) orientadas a la inclusión de las personas con discapacidades. La presente investigación examina el grado en que las percepciones de los empleados sobre dichas políticas están relacionadas con la identificación y el compromiso con la organización, y con el absentismo. Se administró un cuestionario a 104 empleados (tasa de participación: 41,1%). Se realizaron correlaciones, pruebas de varianza del método común, y regresiones lineales. Si bien el efecto de las políticas de RSC orientadas hacia el entorno de la organización han sido las más estudiadas, nuestra investigación pone de relieve el impacto de las políticas internas para la inclusión de las personas con discapacidad sobre el compromiso y la identificación de todos los empleados, las personas con y sin discapacidad, pero no así con el absentismo. Los resultados obtenidos contribuyen significativamente al diseño de estrategias que faciliten y mejoren la normalización del colectivo de personas con discapacidad en el mercado de trabajo, contribuyendo a su inserción laboral

Living together, feeding apart. Trophic ecology of three demersal sharks in the north-east Atlantic

Feeding habits, diets and trophic relationships among three demersal sharks (Galeus melastomus Rafinesque, 1810; Etmopterus spinax (Linnaeus, 1758); and Scyliorhinus canicula (Linnaeus, 1758)) from the Porcupine Bank, Northeast Atlantic were studied. The stomach content analysis revealed differences between the diet of the three species, with a clear preference for benthonic preys in the case of S. canicula, and benthopelagic preys in the case of E. spinax and G. melastomus. The results of this study provide new knowledge about the ecological role of these species in the Porcupine Bank and will be of vital importance for their management and conservation of these species

Results on Argentine (Argentinaspp.), Bluemouth (Helicolenus dactylopterus), Greater forkbeard (Phycis blennoides), Spanish ling (Molva macrophthalma) and ling (Molva molva) from 2014 Porcupine Bank (NE Atlantic) survey

This working document presents the results on four of the most significant deep fish species of the last Porcupine Spanish survey carried in 2014, as well as it updates previous documents presented with the information on the fourteen years (2001-2014) of the Spanish bottom trawl survey on the Porcupine Bank. The document presents total abundances in weight, length frequencies and geographical distributions for Argentinaspp. (mostly A. silus, results on proportions by Argentine species distribution in last surveys are provided), Bluemouth (Helicolenus dactylopterus), Greater fork-beard (Phycis blennoides) and Spanish ling (Molva macrophthalma). Argentinaspp. and Spanish ling presented a decrease in their abundances, whereas Bluemouth remained stable and Greater forkbeard increased slightly. In terms of recruitment 2014 showed larger values than previous years for A. sphyraena, Helicolenus dactylopterusand Molva macrophtalmabut weaker for Phycis blennoides, and A silus. Furthermore results for ling (Molva molva) on the Spanish Porcupine Bank survey are summarizedpresenting the results to the WG so their utility for the assessment could be considered.Versión de edito

An enhanced recruitment of blue whiting in the Porcupine bank (NE Atlantic) during 2020 in response to favourable environmental conditions

A Spanish bottom trawl research survey was conducted between 2001 and 2020 in the Porcupine Bank to retrieve recruitment data. The survey was routinely carried out in September with the objective of assessing the fisheries in the area. The 2020 data showed the largest abundance of age-0 blue whiting (Micromesistius poutassou), with almost twice as much than in the highest previous record (2004). Thus, this study focused on determining the environmental drivers that could explain that anomalously high abundance through their impact on the blue whiting eggs and larvae survival. For this purpose, satellite SST and chlorophyll were analyzed during the spawning season (March-April), along with reanalysis wind, salinity, and ocean currents data. Our results showed particularly low wind conditions during March and April 2020, which triggered the onset of a stable Taylor Column circulation above the Porcupine Bank, helping not only the accumulation of phytoplankton biomass, which promoted secondary productivity, but also larval retention. This was corroborated by a quantile regression fit applied on the blue whiting recruitment data (September), which showed significant positive (negative) correlations with the chlorophyll concentration (wind mixing index) during the spawning season
