Cr. CEE 90. Control of Phytoplankton Dominance. - ref 900911.0004

Oceanographic survey collected in the framework of the following research project: - Métodos de Produccion de Huevos. Estimacion de la biomasa de especies pelagicas de interes comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)-. This Project is funded by the Instituto Espanol de Oceanografia and the main scientific objective is to produce an index and a direct estimate of the biomass of the Gulf of Cadiz anchovy stock using the Daily Egg Production Method (DEPM). Specific aims: a) To estimate the spawning area distribution of anchovy and the daily and total egg production. b) To collect adults to obtain anchovy gonads for atresia and fecundity estimation c) Distribution and abundance of other commercial species of interest: sardine, horse mackerel 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

CR Radprof 0904 Caracterizacion termohalina a lo largo de los perfiles y transectos indicados por lo menos dos al ano como contribucion al logro de los objetivos del programa Internacional CLIVAR mediante la obtencion de registros repetidos en lugares claves oceanicos.

Give an improved estiamtion of the abundance of pelagic fish present in the Mediterranean Sea waters in spring which is the spawning period for these fish species, but focussing in sardine and anchovy. Complementary to this main objective the survey design and strategies will allow the enviroment be characterised by recording differente variables (i. e. temperature, salinity, fluorescence, plankton, winds or air temperature) in vertical and horizontal profiles along the surveyed area with no noticeable extra-effort. As it was pointed out, these variables will help the acoustic estimations be improved whilst an extensive environment characterisation at the spawning time will be done.

Abundance indices, distribution patterns and faunal assemblages of demersal species in the northern coast of Spain (Atlantic Galician shelf and Cantabrian sea shelf), together with the possible driving factors of their distribution. This survey belongs to the research project: ?Evaluacion de Recursos Demersales por Metodos Directos en el Area ICES?. This Project is partly funded by the DCR of the EU and the Education and Science Spanish Ministery.The main objectives of the above mentioned project related with this survey time series are: a) to obtain abundance indices of the main exploited species in the study area; b) to estimate the strength of yearly recruitments of these species and their distribution in the area. c) to study the structure and distribution o the demersal and benthic communities in the area.
