The ECOMED 2006 is an annual echosurvey for estimation of the abundance and biomass of small pelagic fish present in the Mediterranean Sea in autum, at the beginning of spawning period for the sardine (Sardina pilchardus) and the recruitmen period for the anchovy (Engraulis encrasicolus).These main species are sardine and anchovy, but on estimed also Sardinella aurita, Trachurus mediterraneus, T. trachurus, T. picturatus, Boops boops, Scomber japonicus and Scomber scomber.

Oceanographic survey collected in the framework of the following research project: INTERCAMBIOS EN EL ESTRECHO DE GIBRALTAR Y SU RESPUESTA A FORZAMIENTOS METEOROLOGICOS Y CLIMATICOS, INGRES (REN03-01608/MAR). This Project is funded by the Education and Science Spanish Ministery.The technical objetive of the mission is to recover and to deploy a mooring system in a monitoring station (Espartel) in the Strait of Gibraltar to estimate the Mediterranean Outflow accurately (ADCP based observations) and the Atlantic Inflow into the Mediterranean Sea, with the help of indirect estimators and incomplete currentmeter data sets

1.- Estimacion de los indices de abundancia (numero y biomasa), de las especies demersales de mayor interes pesquero, asi como de la fauna asociada a ellas. 2.- Determinacion de la distribucion geografica y batimetrica de las diferentes especies. 3.- Obtencion de las distribuciones de tallas de peces, de las capturas asi como de los crustaceos y moluscos de interes pesquero. 4.- Extraccion de otolitos de merluza. 5.- Obtencion de datos biologicos de las principales especies comerciales: estados de madurez, proporcion de sexos 6.- Obtencion de datos oceanograficos.

Caracterizacion f??sica, biogeoqu??mica y producci??n planct??nica en tres ambientes ecologicos que se observan durante el invierno (aguas continentales,intrusion de la corriente costera superficial paralela a lacosta y aguas oce??nicas) y el estudio de los frentes costeros que delimitan estos ambientes.
