Spanish discards estimates of megrim (Lepidorhombus whiffiagonis) in Subarea VII and Divisions VIIIabd

The Spanish discards estimates of the megrim (Lepidorhombus whiffiagonis) stock of ICES Subarea VII and Divisions VIIIabd (mgw-78) are derived from data compiled by the Spanish on-board sampling program, developed by the Spanish institutes IEO and AZTI following the European Data Collection Regulation (DCR, DCF) guidelines since its implementation in 2003. A description of the Spanish fishery and the respective discards sampling program, as well as an analysis of the sampling level and the estimation process of mgw-78 discards are presented

Estimates of Spanish bottom otter trawl boarfish (Capros aper) discards by area in the Northeast Atlantic area.

Discard estimates for the Spanish bottom otter trawl fleets fishing in the Northeast Atlantic are presented for boarfish (Capros aper). Information was obtained by observers on board under different discard sampling programmes carried out by the Spanish research institute IEO. Raising based on effort (number of trips) was used to estimate total discards in weight and associated coefficients of variation (CV) and number for the fleet. Discards length distributions are presented by year and fishing area. Total estimates indicates different trends in discarding, showing a decreasing trend in north coastal Spanish waters and a increasing trend in western Ireland waters

UN MODELO CAUSAL DE COMPETITIVIDAD EMPRESARIAL PLANTEADO DESDE LA VBR: CAPACIDADES DIRECTIVAS, DE INNOVACIÓN, MARKETING Y CALIDAD

El propósito de esta investigación es desarrollar un modelo explicativo de la competitividad empresarial a partir de factores internos a la empresa. Para ello se identifican los factores de competitividad más importantes en el caso de las empresas manufactureras vascas, así como las variables que permiten caracterizarlos, utilizando técnicas cualitativas basadas en entrevistas con directivos. Los factores resultantes son las capacidades directivas, las capacidades de innovación, las capacidades de marketing y las capacidades de calidad. Tras analizar estos factores bajo la Visión de la empresa Basada en Recursos (VBR), y definir sus escalas de medida, se plantea un modelo causal que relaciona cada uno de ellos con la competividad de la empresa. Este modelo otorga una importancia especial a las capacidades directivas al plantear este factor como precedente del resto de capacidades de la empresa. El modelo es contrastado a través de la técnica de modelado con ecuaciones estructurales utilizando una muestra representativa de la población de empresas manufactureras vascas formada por 861 empresas

Analysis of the small-scale fleet’s coverage under two sampling strategies: from the DCR stock-based to the DCF concurrent sampling in the Northern Spanish coastal gillnets fleet

Working document presented at the WGCATCH 2015 meeting.The Northern Spanish coastal small scale fleet represents a major challenge for sampling due to the multi-species and multi-gear character and the complexity of the fleets’ dynamics. Particularly, the small-scale gillnets called “beta” (GNS_DEF_60-79_0_0) represents a complex Spanish métiers in terms of catches, effort, geographical distribution and the number of exploited species. Comparison of data obtained in 2008, under a stock-based approach, versus concurrent sampling realized in 2014 resulted in the increase of the information obtained and provided to ICES without detected failures in data quality. Concurrent sampling could represent a source of information for small-scale fisheries which often target a set of coastal species some of which are presently unassesed

Anglerfish (Lophius spp.) increasing discards in Spanish OTB fleet (VI-VII ICES). Juveniles availability or sampling artefact?

An update of the yearly estimates of angler sh (black angler (Lophius budegassa) and white angler(Lophius piscatorius) discarded by the Spanish bottom trawl operating in the Northeast Atlantic ocean are presented. Black angler discards increased sharply in the last three year, while UShape with a maximum in 2010 is found for white angler. A 2003 - 2010 sampling methodology review has beeen carried out without detecting any shift in the protocol which could produce overestimation for recent years discards. Fishing covariates related to black angler discard data also indicates that shing practices remain stable along the series. We detect a steady increase in the species rst length of retention L50 from 21; 5cm in 2003 to a range 23cm - 25cm between 2004 - 2008 and 28cm since 2009. We conclude that interaction between the industry adoption of a Minimum Weigth Landing (500g) and the strength of recruitment indices explain the increase in amounts of angler discards

Deep Species Results from Spanish Discard Sampling Programme

Estimations of deep species discards from three Spanish bottom otter trawl m etiers operating in the Northeast Atlantic ICES V I, V II, V IIIc and North IXa are presented in this paper. Information has been ob- tained from the `Spanish Discard Sampling Programme' carried out by the IEO. Trip was the sampling unit, being raised to eet level using sh- ing e ort as auxiliary variable. Discard weigth estimates from time series of seven years (2003-2009) is presented for twelve species. Further, dis- card length distributions are presented for those species that have been observed whitin discarded fraction for more than three years. Estimates show high between-years variation in discard amounts, exceeding 35% CV in almost all cases. Results show that the largest amounts of discards of most of the species occur at depths less than 600m. Low market value is the main factor that forces the eet to discard most of deep species

Elasmobranches Results from Spanish Discard Sampling Programme

A discard Elasmobranches species composition estimates for the Spanish bottom otter and pair trawl fleets operating in the Northeast Atlantic ICES Subareas VI, VII, VIII and North IX are presented. Information has been obtained from the “Spanish Discard Sampling Programme” carried out by the IEO. Time series provide information on discarded catch (in weight and number) and length distributions since 2003 to 2009. Eighteen species were selected in order to show the most important ones occurring in Spanish discards. Trip was the sampling unit, being raised to fleet level using fishing effort as auxiliary variable. Discard estimates for these species show high betweenyears variation, exceeding 50% CV in all cases. Further exploratory data analysis was carried for the four most discarded species
