Capa que contiene la distribución espacial de las localizaciones puntuales de praderas de angiospermas marinas de las costas españolas elaborada a partir de la fusión de varias fuentes disponibles, seleccionadas siguiendo el criterio de expertos. La información está agrupada por comunidades autónomas ya que es esta unidad administrativa la que aporta una red organizada que incluye tanto las fuentes de datos como personas expertas y conocedoras de esos datos y que aplicaron su criterio de experto en la construcción de esta capa. La elaboración de este conjunto de información comenzó en 2013 y concluyó en 2015 con la publicación de la primera edición del Atlas de las praderas marinas de España. Es un trabajo de integración de informaciones de muy variada naturaleza por lo que su grado de fiabilidad y precisión es muy variable y su uso y aplicación deben estar acotados dentro de tales circunstancias y no debe desligarse de las fuentes de referencia originales empleadas para la elaboración de los mapas finales.

Spanish Porcupine bottom trawl survey aims to collect data on the distribution and relative abundance, and biological information of commercial fish in Porcupine bank area (ICES Division VIIb-k). The primary target species are hake, monkfish, white anglerfish and megrim, which abundance indices are estimated by age, with abundance indices also estimated for Nephrops, four-spot megrim and blue whiting. Data collection is also collected for several other demersal fish species and invertebrates.
The main objective is to know the state of the populations of the species objective: their abundance, biomass and demographic structure, and the conditions oceanographic in the Bank. Species objective: Gadus Morhua, Sebastes Marinus, Sebastes Mentella, Sebastes fasciatus, Hippoglossoides Platessoides, Reinhardtius Hippoglossoides, Macrourus berglax and Pandalus borealis.
The main objective is the collection of data that allow estimate the abundance, biomass and demographic structure of the species of commercial interest in the regulation area NAFO, until a maximum depth of 1500 m.
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 mackerel stock and an index for the southern and western horse mackerel 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.
