Oceanographic survey collected in the framework of the following research project: ¿Métodos de Producción de Huevos. Estimación de la biomasa de especies pelágicas de interés comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)¿. This Project is funded by the Instituto Español de Oceanografía and the main scientific objective is to produce an index and a direct estimate of the biomass of the Northeast Atlantic mackerel stock and the southern and western horse mackerel stocks using the Annual Egg Production Method (AEPM). Specific aims:a) To estimate the spawning area distribution of mackerel and horse mackerel and the daily and total mackerel and horse mackerel egg production. b) To collect adults to obtain mackerel and horse mackerel gonads for atresia and fecundity estimation c) Distribution and abundance of other commercial species of interest: sardine, anchovy, hake, blue whiting.d) To describe the oceanographic and meteorological character of the area of study with the aim of relating environmental conditions (temperature, salinity, currents) with the spatial distribution of the ichthyoplankton
Monthly survey to study thermohaline and biological characterization of water masses in the East-North Atlantic.
The MEDITS survey (International bottom trawl survey in the Mediterranean is organized to monitor the demersal resources in the Mediterranean. It intends to produce relevant information to support the fishery policy by collecting abundance data and biological parameters of fish, crustaceans and cephalopods species. The hauls are positioned following a depth stratified sampling scheme with random drawing of the positions within each stratum. The hauls are made in the same position from year to year. The following depths are fixed in all areas as strata limits : 10 - 50 m, 50 - 100 m, 100 - 200 m, 200 - 500 m, 500 - 800 m. The protocols, including the specifications of the standard gear are described in an instruction manual. The series began in 1994 with one yearly survey. Ten Mediterranean countries are applying the Medits protocols (about 1100 hauls per year).
