This dataset gives information on larval abundances at different layers of the water column in two fixed stations sampled in the shelf zone of the Catalan coast in May and June 1992. This research explores the diel vertical distribution in relation to oceanographic features. Larvae of most species (e.g. sparids and anchovy) occurred above the thermocline, while a few species such as those of gobids and callionymids appeared in the deeper layers, "Estudio de los mecanismos que afectan al reclutamiento y asentamiento en especies litorales".

The dataset presents the number of mesopelagic Decapoda collected during the CSIC-SUMMER survey carried out in October 2020 in five zones around the Iberian Peninsula: south of Balearic Islands and Alboran Sea in the western Mediterranean, and Gulf of Cadiz, off Lisboa and off Galicia in the Atlantic. The scientific midwater trawl Mesopelagos (Meillat, 2012) fitted with the VERDA Multisampler (Castellón and Olivar, 2023), placed at the end of the net, was used to collect specimens at seven layers of the water column. The depth of the net was controlled by a SCANMAR system. In the five zones hauls were carried out day and night to study vertical distribution and migration patterns. Samples covered between 0 and 700 m, and discriminated seven layers in the water column. This file presents numerical abundance by taxa, generally to species level in the different hauls performed. These data were obtained within the European Union Project 'Sustainable Management of Mesopelagic Resources' (SUMMER, Grant Agreement 817806) as funded by the Horizon 2020 Research and Innovation

MAS-1 Cruise (29GD20041122) carried out on the Research Vessel García del Cid in 2004, The purpose of the project is to find out the spatial structure of the distribution of planktonic organisms with a large spatial resolution. It is intended to study various biological aspects (abundance, growth, condition) and types (micro and mesoplankton, eggs, hake larvae, sardine and anchovy.Throughout the campaign a record of continuous data of surface temperature and salinity will be obtained and the currents will be measured by means of the ADCP Obtaining hydrographic profiles using a CTD probe equipped with fluorescence sensor (parameters obtained: conductivity, temperature, density and fluorescence) Obtaining meteorological data (speed and wind direction) Sampling of microzzoplankton by vertical fishing with a Calvet net along the water column Sampling of mezozooplankton and macrozooplankton (including eggs and fish larvae). Oblique type plankton catches with a Bongo net will be carried out during this phase of the campaign The samples to be used for the evaluation of abundances will be concentrated, fixed and stored for further analysis in the laboratory. Larvae from one of the network's sleeves will be selected on board and stored in formaldehyde or liquid nitrogen. for further analysis Sampling plankton through an LHPR net In the wet laboratory, a preliminary analysis of the mesozooplankton samples will be carried out to determine the maximum larval abundance strata In the most abundant strata, horizontal fishing will be carried out with the LHPR net in order to determine the horizontal structure with a finer resolution

SUMMER Cruise (29SG20200929) carried out on the Research Vessel Sarmiento de Gamboa in 2020, SUMMER “Sustainable Management of Mesopelagic Resources". The project is part of the H2020 Program of "Food security, sustainable agriculture, marine and maritime research and bioeconomy" and covers ecological aspects of mesopelagic communities. A fundamental part of this research lies in obtaining samples of plankton and micronekton from the mesopelagic zone to the epipelagic layers, acoustic records in the same places, and information on the hydrographic parameters throughout the water column. The survey will have 2 main study sites in eastern Iberia- western Mediterranean sea (oligotrophic region), and 2 more in western Iberia (productive region). In each of the 4 sites repeated samples will be performed day and night during 3 journeys. From Cape San Vicente to Lisbon latitude, the work will focus on the location of Eddies of Mediterranean water (MEDIS), therefore CTDs will be the priority. To study the influence on these MEDIS on mesopelagic populations, plankton hauls will be also performed in particular locations. We foresee to spend at least 3 days per study site. Two days (day and night) will be devoted to sample micronekton (small fishes, crustaceans, cephalopods etc) and mesozooplankton in the water column (from the mesopelagic to the epipelagic zone). Then, to obtain more accurate view of the migratory populations, one of the journeys will focus on the study of surface layer

FIL-I Cruise (29GD19981103) carried out on the Research Vessel García del Cid in 1998, The study focuses on the analysis of the physiological and developmental conditions of sardine larvae. It is intended to compare the physiological situation of larvae developed at various points (platform, slope) and in different periods

The values of natural abundance of stable isotopes were measured in 13 micronekton fish species sampled during the BATHYPELAGIC cruise (North Atlantic, June 2018). This dataset contains the values obtained for carbon and nitrogen in bulk tissues, and nitrogen values in amino acids. Length and biomass data for each individual analyzed are also provided. Fishes were collected using a ''Mesopelagos” net (5x7 m mouth opening, 58 m total lenght) equipped with graded-mesh netting (starting with 30 mm and ending with 4 mm) and a multi-sampler for collecting samples from 5 different depth layers (Olivar et al., 2017). Individual fish were eviscerated, freeze-dried and weighted. Aliquots of muscular tissue (or whole individuals for species of small size) were analyzed in an elemental analyzer (bulk tissues, Olivar et al., 2019) or a gas chromatograph (derivatized amino acids, Mompeán et al., 2016) coupled to isotope-ratio mass spectrometers.
