THE AQUACULTURE OF SOLE, SOLEA SENEGALENSIS, IS SEEN AS AN EXCELLENT OPTION OF DIVERSIFICATION AND ECONOMIC EXPANSION OF THE SECTOR IN EUROPE, WHICH HAS REDUCED ITS PRODUCTION SINCE 2000 AN AVERAGE OF -0.9 % PER YEAR. HOWEVER, THE SCIENTIFIC AND TECHNOLOGICAL EFFORTS OF THE LAST DECADE HAVE NOT SOLVED THE REPRODUCTIVE PROBLEMS OF CAPTIVE SOLES (F1), AND HORMONAL TREATMENTS ARE ONLY EFFECTIVE TO INDUCE MATURATION AND RELEASE OF GAMETES, BUT DO NOT GUARANTEE SUSTAINABLE CULTIVATION, AS THE PRODUCTION OF WILD BREEDERS OBTAINED IN THE NATURAL ENVIRONMENT CONTINUES TO DEPEND. IN PREVIOUS PROJECTS WE INVESTIGATED THE NEUROENDOCRINE CONTROL OF THE REPRODUCTION OF SOLE, ANALYSING THE ROLE OF THE PINEAL ORGAN, THE RHYTHMS OF MELATONIN AND LAYING AND NEW NEUROENDOCRINE FACTORS OF INTEREST IN AQUACULTURE (REPROSOLEA AND CRONOSOLEA), THE HYPOTHALAME-HYPOPHYSIS-GONADAL AXIS (SOLER AND REPROSOLE), THE ONTGENIA OF THE CIRCADIAN CLOCK AND THE DEVELOPMENT OF LARVAE (CIRCASOLE AND CRONOSOLEA). HOWEVER, RHYTHMS IN GAMETOGENESIS OR EMBRYOGENESIS, THE PERI-FERTILISATION STAGES MORE SENSITIVE TO THE EPIGENETIC CHANGES CAUSED BY THE ENVIRONMENT, WERE NOT CONTEMPLATED. THE GENERAL OBJECTIVE OF SOLEMBRYO IS TO DEEPEN THE MECHANISMS OF SENSITIVITY TO LIGHT AND TEMPERATURE, WITH PARTICULAR EMPHASIS ON THE EMBRYONAL AND LARVAL PERIOD OF SOLE, AND TO CLARIFY THE ROLE PLAYED BY DAILY CYCLES OF LIGHT AND TEMPERATURE (AND THEIR ALTERATIONS) ON THE FINAL STAGES OF GAMETOGENESIS, EMBRYONIC AND LARVAL DEVELOPMENT, METAMORPHOSIS, SEXUAL DETERMINATION/DIFFERENTIATION AND, ULTIMATELY, REPRODUCTION OF THIS SPECIES. TO THIS END, WE HAVE ARTICULATED IN THE PROPOSAL A SERIES OF SPECIFIC OBJECTIVES, BOTH METHODOLOGICAL AND SCIENTIFIC, TO ENSURE THE STABLE PRODUCTION OF QUALITY LARVAE AND FRY, DEFINING ADEQUATE FERTILISATION AND BREEDING PROTOCOLS THAT DO NOT ALTER THE NORMAL DEVELOPMENT OF EMBRYOS AND LARVAE, OR THE REPRODUCTIVE CAPACITY OF THE SPECIMENS WHEN THEY REACH SEXUAL MATURATION. THE ACTIVITIES PROPOSED IN SOLEMBRYO ARE PART OF THE SPANISH STRATEGY OF SCIENCE AND TECHNOLOGY AND INNOVATION (2013-2020) AND, IN PARTICULAR, CHALLENGE 2: “FOOD SAFETY AND QUALITY; PRODUCTIVE AND SUSTAINABLE AGRICULTURAL ACTIVITY; SUSTAINABILITY OF NATURAL RESOURCES, MARINE RESEARCH AND MARITIMA”. THE THEME OF THE PROJECT FOCUSES ON THE FIRST DESCRIPTOR OF THIS GREAT CHALLENGE: “THE PRODUCTION AND SUSTAINABLE MANAGEMENT OF AGRICULTURE, LIVESTOCK, AQUACULTURE, FOREST RESOURCES AND FISHERIES, THE AGRI-FOOD CHAIN AND ITS TRACEABILITY, THE PROTECTION OF AGRICULTURAL AND FORESTRY CROPS, ANIMAL HEALTH AND WELFARE, THE PRODUCTION AND TRANSFORMATION OF BIOMASS AND MITIGATION AND ADAPTATION TO CLIMATE CHANGE”. THE PROJECT ALSO ADDRESSES ASPECTS OF GREAT INTEREST TO UNDERSTAND THE HARMFUL EFFECTS THAT CLIMATIC CHANGE CAN HAVE ON AQUATIC BIOTA AS TEMPERATURE AND ITS DAILY CYCLES PLAY A KEY ROLE IN CONTROLLING THE PROPORTION OF SEXES, AND SEASONAL TEMPERATURE CHANGES ARE CRUCIAL FOR THE CONTROL OF REPRODUCTION IN SOLE. EVIDENCE OF THIS RELEVANCE IS THE EXISTENCE OF EUROPEAN INITIATIVES IN THE HORIZON 2020 ROADMAP WITH PRIORITY THEMES AIMED AT DEVELOPING ECOSISTEMICA-BASED APPROACHES FOR EUROPEAN AQUACULTURE, AND AT CLARIFYING THE ENVIRONMENTAL IMPACT LINKED TO CLIMATE CHANGE AND GLOBAL WARMING.

LA ACUICULTURA DEL LENGUADO, SOLEA SENEGALENSIS, SE VISLUMBRA COMO UNA EXCELENTE OPCION DE DIVERSIFICACION Y EXPANSION ECONOMICA DEL SECTOR EN EUROPA, QUE HA REDUCIDO SU PRODUCCION DESDE 2000 UNA MEDIA DEL -0,9% ANUAL. SIN EMBARGO, LOS ESFUERZOS CIENTIFICO-TECNOLOGICOS DE LA ULTIMA DECADA NO HAN RESUELTO LOS PROBLEMAS REPRODUCTIVOS DE LOS LENGUADOS PRODUCIDOS EN CAUTIVIDAD (F1), Y LOS TRATAMIENTOS HORMONALES SOLO SON EFECTIVOS PARA INDUCIR LA MADURACION Y LIBERACION DE GAMETOS, PERO NO GARANTIZAN EL CULTIVO SOSTENIBLE, AL SEGUIR DEPENDIENDO LA PRODUCCION DE REPRODUCTORES SALVAJES OBTENIDOS EN EL MEDIO NATURAL. EN PROYECTOS ANTERIORES INVESTIGAMOS EL CONTROL NEUROENDOCRINO DE LA REPRODUCCION DEL LENGUADO, ANALIZANDO EL PAPEL DEL ORGANO PINEAL, LOS RITMOS DE MELATONINA Y PUESTA Y NUEVOS FACTORES NEUROENDOCRINOS DE INTERES EN ACUICULTURA (REPROSOLEA Y CRONOSOLEA), EL EJE HIPOTALAMO-HIPOFISIS-GONADAL (SOLER AND REPROSOLE), LA ONTOGENIA DEL RELOJ CIRCADIANO Y EL DESARROLLO DE LARVAS (CIRCASOLE Y CRONOSOLEA). SIN EMBARGO, NO SE CONTEMPLARON LOS RITMOS EN GAMETOGENESIS O EMBRIOGENESIS, LOS ESTADIOS PERI-FERTILIZACION MAS SENSIBLES A LOS CAMBIOS EPIGENETICOS PROVOCADOS POR EL AMBIENTE. EL OBJETIVO GENERAL DE SOLEMBRYO ES PROFUNDIZAR EN LOS MECANISMOS DE SENSIBILIDAD A LA LUZ Y LA TEMPERATURA, CON ESPECIAL ENFASIS EN EL PERIODO EMBRIONARIO Y LARVARIO DEL LENGUADO, Y ESCLARECER EL PAPEL QUE DESEMPEÑAN LOS CICLOS DIARIOS DE LUZ Y TEMPERATURA (Y SUS ALTERACIONES) SOBRE LAS ETAPAS FINALES DE LA GAMETOGENESIS, EL DESARROLLO EMBRIONARIO Y LARVARIO, LA METAMORFOSIS, LA DETERMINACION/DIFERENCIACION SEXUAL Y, EN ULTIMA INSTANCIA, LA REPRODUCCION DE ESTA ESPECIE. PARA ELLO, HEMOS ARTICULADO EN LA PROPUESTA UNA SERIE DE OBJETIVOS ESPECIFICOS, TANTO METODOLOGICOS COMO CIENTIFICOS, QUE PERMITAN ASEGURAR LA PRODUCCION ESTABLE DE LARVAS Y ALEVINES DE CALIDAD, DEFINIENDO PROTOCOLOS DE FERTILIZACION Y CRIA ADECUADOS QUE NO ALTEREN EL NORMAL DESARROLLO DE LOS EMBRIONES Y LARVAS, NI LA CAPACIDAD REPRODUCTIVA DE LOS EJEMPLARES CUANDO ALCANCEN LA MADURACION SEXUAL. LAS ACTIVIDADES PLANTEADAS EN SOLEMBRYO SE ENMARCAN DENTRO DE LA ESTRATEGIA ESPAÑOLA DE CIENCIA Y TECNOLOGIA Y DE INNOVACION (2013-2020) Y, EN CONCRETO, EN EL RETO Nº 2: "SEGURIDAD Y CALIDAD ALIMENTARIA; ACTIVIDAD AGRARIA PRODUCTIVA Y SOSTENIBLE; SOSTENIBILIDAD DE RECURSOS NATURALES, INVESTIGACION MARINA Y MARITIMA". LA TEMATICA DEL PROYECTO SE CENTRA EN EL PRIMER DESCRIPTOR DE ESTE GRAN RETO: "LA PRODUCCION Y GESTION SOSTENIBLE DE LA AGRICULTURA, LA GANADERIA, LA ACUICULTURA, LOS RECURSOS FORESTALES Y LA PESCA, LA CADENA AGROALIMENTARIA Y SU TRAZABILIDAD, LA PROTECCION DE LOS CULTIVOS AGRICOLAS Y FORESTAL, LA SANIDAD Y EL BIENESTAR ANIMAL, LA PRODUCCION Y TRANSFORMACION DE BIOMASAS Y LA MITIGACION Y ADAPTACION AL CAMBIO CLIMATICO". EN EL PROYECTO TAMBIEN SE ABORDAN ASPECTOS DE GRAN INTERES PARA ENTENDER LOS EFECTOS NOCIVOS QUE EL CAMBIO CLIMATICO PUEDE EJERCER SOBRE LA BIOTA ACUATICA YA QUE LA TEMPERATURA Y SUS CICLOS DIARIOS JUEGAN UN PAPEL CLAVE EN EL CONTROL DE LA PROPORCION DE SEXOS, Y LOS CAMBIOS ESTACIONALES DE TEMPERATURA RESULTAN CRUCIALES PARA EL CONTROL DE LA REPRODUCCION EN EL LENGUADO. UNA PRUEBA DE ESTA RELEVANCIA ES LA EXISTENCIA DE INICIATIVAS EUROPEAS EN EL PLAN DE TRABAJO HORIZONTE 2020 CON TEMATICAS PRIORITARIAS DESTINADAS A DESARROLLAR APROXIMACIONES DE BASE ECOSISTEMICA PARA LA ACUICULTURA EUROPEA, Y A DILUCIDAR EL IMPACTO AMBIENTAL LIGADO AL CAMBIO CLIMATICO Y CALENTAMIENTO GLOBAL.

THE AQUACULTURE OF SOLE, SOLEA SENEGALENSIS, IS SEEN AS AN EXCELLENT OPTION OF DIVERSIFICATION AND ECONOMIC EXPANSION OF THE SECTOR IN EUROPE, WHICH HAS REDUCED ITS PRODUCTION SINCE 2000 AN AVERAGE OF -0.9 % PER YEAR. HOWEVER, THE SCIENTIFIC AND TECHNOLOGICAL EFFORTS OF THE LAST DECADE HAVE NOT SOLVED THE REPRODUCTIVE PROBLEMS OF CAPTIVE SOLES (F1), AND HORMONAL TREATMENTS ARE ONLY EFFECTIVE TO INDUCE MATURATION AND RELEASE OF GAMETES, BUT DO NOT GUARANTEE SUSTAINABLE CULTIVATION, AS THE PRODUCTION OF WILD BREEDERS OBTAINED IN THE NATURAL ENVIRONMENT CONTINUES TO DEPEND.
