The main objective of this series of individual cruises is to produce both an index and a direct estimate of the biomass of the north east Atlantic and Bay of Biscay sardine stock and an index for the southern and western sardine stocks. The general method is to quantify the freshly spawned eggs in the water column on the spawning grounds, report egg species identification and staging. To be able to establish a relationship between eggs and biomass of the spawning stock, the fecundity of the females must also be determined. The realised fecundity is used in combination with the calculated number of freshly spawned eggs in the water to render an estimate of the spawning stock biomass. To provide reliable estimates of the quantity of spawned eggs and the fecundity an extensive coverage of the spawning area is required both in time and space. Provide temperature data from the CTD casts will be used for the egg ageing procedure. Other environmental variables will be used for hydrographic and spawning area characterization.

- Estimate the abundance of cetaceans in oceanic and shelf waters of the European Atlantic in 2016. - These estimates will give the necessary information to evaluate the good environmentla status and the conservation status of the main species of cetaceans in the Atlantic. - In addition these estimates are needed to evaluate the impact of the different anthropogenic pressures on the populations of these species.

Main objectives: Estímate egg abundance for mackerel and horse mackerel in surveyed area Estimate sardine spawning area in surveyed area by CUFES Collect mackerel adult samples to estimate adult parameters by pelagic trawls Secondary objectives: Estimate egg and larva abundances for sardine, anchovy, hake Measure the salinity , temperature depth in the water column using ctd

Abundance indices, distribution patterns and faunal assemblages of demersal species in the Flemish Cap bank, together with the possible driving factors of their distribution. This survey belongs to the research project: 'Biología Pesquera pesquerías Lejanas'. This Project is partly funded by the DCR of the EU and the Education and Science Spanish Ministery. T 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 Flemish Cap bank b) to estimate the strength of yearly recruitments of these species and their distribution in the bank. c) to study the structure and distribution o the demersal and benthic communities in the area
