Data Provision for Science-Based FAD Fishery Management: Spanish FAD Management Plan as a Case Study

The use of fish aggregating devices (FADs) in tropical tuna fisheries has increased significantly during recent decades. Concurrently, concern about juvenile tuna mortality, bycatch, and marine debris associated with FAD fisheries increased, and this led to the implementation of FAD management measures and more sustainable designs (e.g., non-entangling or biodegradable FADs, limits on active FADs, etc.). This document reviews data collection and reporting requirements of tuna-Regional Fisheries Management Organizations (t-RFMOs) on drifting FADs and summarizes the work carried out since 2010 under the Spanish FAD management plan to create an adequate standard data collection aimed at improving science-based decision making. The aim of this study is to assist in the strengthening of data collection systems through: (1) a review of the existing data requirements, (2) a review of the status of FAD data collection worldwide and identification of data gaps, and (3) recommendations aimed at improving FAD management through the strengthening of FAD data requirements. Due to the complexities of data collection, we summarize the difficulties faced when processing the data and propose concrete and practical solutions to improve both the data collection system and information quality.Postprin

Allergenicity reduction of cow's milk proteins using latex peptidases

The present study evaluated four laticifer fluids as a novel source of peptidases capable of hydrolyzing proteins in cow´s milk. The latex peptidases from Calotropis procera (CpLP), Cryptostegia grandiflora (CgLP), and Carica papaya (CapLP) were able to perform total hydrolysis of caseins after 30 min at pH 6.5, as confirmed by a significant reduction in the residual antigenicity. Casein hydrolysis by Plumeria rubra latex peptidases (PrLP) was negligible. Moreover, whey proteins were more resistant to proteolysis by latex peptidases; however, heat pretreatment of the whey proteins enhanced the degree of hydrolysis and reduced the residual antigenicity of the hydrolysates. The in vivo assays show that the cow´s milk proteins hydrolysed by CgLP and CapLP exhibited no immune reactions in mice allergic to cow´s milk, similar to a commercial partially hydrolysed formula. Thus, these peptidases are promising enzymes for the development of novel hypoallergenic formulas for children with a milk allergy.Fil: Oliveira, João P. B..

En este documento se presentan datos de la flota española, estrategias de pesca, zonas de pesca, capturas de las especies objetivo, esfuerzos, rendimientos (CPUEs), coberturas de muestreos y distribuciones de talla de las especies objetivo y accesoria de la flota atunera de cerco y de la flota de cañeros de cebo vivo que faena en el Océano Atlántico Tropical. El número de barcos de cerco que operó durante este último año disminuyó en 2 unidades, aunque la captura total aumentó ligeramente durante 2016. En éste último año, se realizaron dos veces más lances a objeto que a banco libre. En términos de porcentaje el 68 % correspondió a Objetos y el 32 % a Banco Libre. Los pesos medios de los ejemplares capturados han sido: para rabil 8,5 kg (4,1 kg objeto y 25,5 kg banco libre); para el listado 1,97 kg (1,9 kg objeto y 2,67 kg banco libre) y para patudo 3,8 kg (3,3 kg objeto y 24,3 kg banco libre). El rabil (YFT) talla modal de captura 42 cm a Objeto (OB) y cuatro tallas modales de 42 cm, 58 cm, 106 cm y 138 cm para las capturas a Banco libre (FS) en 2016. El listado (SKJ) una talla modal de captura, 64 cm para Objeto (OB) y dos tallas modales de 64 cm y 72 cm para Banco libre (FS) en 2016. El patudo (BET) una única talla modal de captura 40 cm para Objeto (OB) y dos tallas modales de 42 cm y 94 cm para Banco libre (FS) en 2016.En prens

Estadística de las pesquerías españolas atuneras, en el Océano Atlántico Tropical, período 1990 a 2017

This document sets out the data for the Spanish fleet, strategies, fishing areas, catches of target species, effort, CPUEs, samplings and size distributions of target species. In 2017, total catch decreased by 5%. Twice as many sets have been carried out on objects than on free schools. More than 80% were conducted on objects and less than 20% on free schools. Average weights were: 5.3 kg for yellowfin tuna (3.8 kg on objects and 31 kg on free schools); 1.6 kg for skipjack (1.6 kg on objects and 2.03 kg on free schools); and 3.37 kg for bigeye tuna (3.27 kg on objects and 37.9 kg on free schools). The modal size for yellowfin tuna caught on objects is 46 cm and the two modal sizes for free school catches are 52 and 150 cm. The modal size for skipjack caught on objects is 42 cm and the modal sizes for free schools are 46, 55 and 64 cm. There is a single modal size for bigeye tuna caught on objects, i.e. 42 cm, and three modal sizes for free schools, i.e. 42, 114 and 146 cm

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
