    Description: The aim of the present study was to analyse growth differences in Norway lobster larvae, Nephorps norvegicus. To date very few studies have used nucleic acids and protein contents to characterize larval stages in crustaceans. DNA, RNA and protein contents were quantified and used as potential indirect measures of growth. Fed and starved larvae were reared at different temperatures (6º, 12º, 18ºC) from hatching to the end of stage III (metamorphosis). During this time, larval growth was measured in samples taken every 1-4 days as a function of day-degrees. Growth was significantly higher in fed larvae compared to starved larvae at 12º and 18ºC, while no significant differences were observed at 6ºC. Starved individuals did not pass through the first moult. Duration of the larval moult-cycle varied with temperature. Stage III was reached during the third week at 18ºC, while it took five weeks at 12ºC. The RNA:DNA ratio and the protein:DNA ratio appeared to be viable indicators of growth in Norway lobster larvae.

    Description: Estudios oceanográficos realizados en aguas marinas cubanas han permitido identificar grandes diferencias de temperatura en la distribución vertical de las aguas oceánicas adyacentes; estos gradientes térmicos pueden utilizarse para la generación de energía eléctrica a partir del uso de energía térmica marina. Esta tecnología tiene ventajas secundarias, debido a que el agua fría bombeada desde las profundidades es rica en sustancias nutritivas y sin agentes patógenos la que puede ser utilizada en el cultivo de especies marinas. Otras fuentes de energía marina que pueden ser utilizadas como generadoras de energía eléctrica se relacionan con las mareas y la intensidad de las corrientes marinas, sobre todo en canales y pasas donde los flujos se incrementan.

    Description: A twenty-year period of severe land subsidence evolution in the Alto Guadalentín Basin (southeast Spain) is monitored using multi-sensor SAR images, processed by advanced differential interferometric synthetic aperture radar (DInSAR) techniques. The SAR images used in this study consist of four datasets acquired by ERS-1/2, ENVISAT, ALOS and COSMO-SkyMed satellites between 1992 and 2012. The integration of ground surface displacement maps retrieved for different time periods allows us to quantify up to 2.50 m of cumulated displacements that occurred between 1992 and 2012 in the Alto Guadalentín Basin. DInSAR results were locally compared with global positioning system (GPS) data available for two continuous stations located in the study area, demonstrating the high consistency of local vertical motion measurements between the two different surveying techniques. An average absolute error of 4.6 ± 4 mm for the ALOS data and of 4.8 ± 3.5 mm for the COSMO-SkyMed data confirmed the reliability of the analysis. The spatial analysis of DInSAR ground surface displacement reveals a direct correlation with the thickness of the compressible alluvial deposits. Detected ground subsidence in the past 20 years is most likely a consequence of a 100–200 m groundwater level drop that has persisted since the 1970s due to the overexploitation of the Alto Guadalentín aquifer system. The negative gradient of the pore pressure is responsible for the extremely slow consolidation of a very thick (〉 100 m) layer of fine-grained silt and clay layers with low vertical hydraulic permeability (approximately 50 mm/h) wherein the maximum settlement has still not been reached.

    Description: The IOC-ICES-PICES Harmful Algal Event Database (HAEDAT) was used to describe the diversity and spatiotemporal distribution of harmful algal events along the Atlantic margin of Europe from 1987 - 2018. The majority of events recorded are caused by Diarrhetic Shellfish Toxins (DSTs). These events are recorded annually over a wide geographic area from southern Spain to northern Scotland and Iceland, and are responsible for annual closures of many shellfish harvesting areas. The dominant causative dinoflagellates, members of the morphospecies ‘Dinophysis acuminata complex’ and D. acuta, are common in the waters of the majority of countries affected. There are regional differences in the causative species associated with PST events; the coasts of Spain and Portugal with the dinoflagellates Alexandrium minutum and Gymnodinium catenatum, north west France/south west England/south Ireland with A. minutum, and Scotland/Faroe Islands/Iceland with A. catenella. This can influence the duration and spatial scale of PST events as well as the toxicity of shellfish. The diatom Pseudo-nitzschia australis is the most widespread Domoic Acid (DA) producer, with records coming from Spain, Portugal, France, Ireland and the UK. Amnesic Shellfish Toxins (ASTs) have caused prolonged closures for the scallop fishing industry due to the slow depuration rate of DA. Amendments to EU shellfish hygiene regulations introduced between 2002 and 2005 facilitated end-product testing and sale of adductor muscle. This reduced the impact of ASTs on the scallop fishing industry and thus the number of recorded HAEDAT events. Azaspiracids (AZAs) are the most recent toxin group responsible for events to be characterised in the ICES area. Events associated with AZAs have a discrete distribution with the majority recorded along the west coast of Ireland. Ciguatera Poisoning (CP) has been an emerging issue in the Canary Islands and Madeira since 2004. The majority of aquaculture and wild fish mortality events are associated with blooms of the dinoflagellate Karenia mikimotoi and raphidophyte Heterosigma akashiwo. Such fish killing events occur infrequently yet can cause significant mortalities. Interannual variability was observed in the annual number of HAEDAT areas with events associated with individual shellfish toxin groups. HABs represent a continued risk for the aquaculture industry along the Atlantic margin of Europe and along the Atlantic margin of Europe and should be accounted for when considering expansion of the industry or operational shifts to offshore areas.
