Description parameter
in general, a very high variability in time, and how in a number of cases there are significant changes in the trend of the first cycle to the second, but it is difficult to assess on a case-by-case basis and the 6-year cycle compared to the 20 years of the previous cycle does not make it easy to draw clear conclusions.

talla de todas las especies de peces costeros en el piso infralitoral rocoso (cm). La comunidad íctica se ha evaluado utilizando el método de censos visuales subacuáticos, método no destructivo y basado en los procedimientos estandarizados de Harmelin-Vivien et al. (1985). En cada censo se toman datos de abundancia y talla de las especies ícticas presentes. Este tipo de muestreo ha sido testado en multitud de trabajos y se ha comprobado de manera muy positiva su eficacia para el muestreo de comunidades ícticas. Los buceadores que han llevado a cabo el muestreo son buceadores entrenados que han realizado censos de prueba para testar las diferencias entre observador. La unidad muestral en este caso ha sido el transecto de 50 x 5 m (250 m2), marcado sobre el fondo marino por medio de una cinta métrica que el buceador va largando en una dirección preestalecida y manteniedo la profundidad y el tipo de hábitat. Cada transecto se lleva a cabo por un solo buceador, que cuantifica la abundancia y la talla de las especies presentes. Las especies se contaron a 2,5 m de cada lado de la cinta métrica, a una velocidad de aproximadamente 2,5 m·min-1, utilizando unos 20 minutos para examinar toda el área del transecto. Una vez acabado este primer transecto, se lleva a cabo, de vuelta, un segundo transecto, en este caso de 50 x 1 m (50 m2), revisando los agujeros y grietas, en que el que se censa la abundancia y talla de las especies crípticas de peces. Los censos se llevaron a cabo entre las 09:00 y las 17:00 h para excluir los patrones nocturnos del comportamiento de los peces (Gray et al. 1998). Para minimizar el error en la estima de talla se ajustaba a clases de talla de 2 cm para especies pequeñas y a clases de talla de 5 cm para especies de gran tamaño. Además se registraban diversas variables para la caracterización ambiental del transecto evaluado (profundidad, temperatura del agua, corriente, luminosidad, visibilidad, porcentaje de cobertura de cada sustrato en cada transecto, rugosidad, pendiente del área de estudio en grados respecto a la horizontal y porcentaje de refugios).

Description criteria
Species not commercially exploited: This indicator should be applied in the case of species and stocks that are not subject to catches by commercial fleets, such as marine mammals, turtles or seabirds. See explanation below on the reasons for not applying in the case of fish and demersal cephalopods from the shelf life of the platform. In the case of demersal fish and cephalopods, follow the proposed EU decision on criteria for defining “Good Environmental Status” (BEA), would require estimating by-catch rates by the fleet for almost all species, since most are subject to incidental catch or discard by fishing fleets, especially trawls, without being a direct target of commercial fisheries, in fact many are subject to sales and harvesting. Therefore, the concept of incidental catch is not considered to be applicable to these species and it is not considered feasible to calculate the mortality rate derived from incidental catches.
The results obtained in the previous evaluation have been updated by analysing all the data from the campaigns carried out from 2011 to 2017 in terms of abundance and biomass of the stocks that are considered to be actually sampled in the campaigns. The indicators have been estimated on the basis of the results of the IBTS campaigns between 2011 and 2017 (2018 is done at the end of September and is still in the process of reviewing the results and analysis data). Insufficient data. The assessment of this criterion requires a more detailed analysis, since in many species there is great natural variability, and changes from year to year are very marked and cannot easily be interpreted in terms of trend. A situation very similar to that of the first assessment is observed, being an indicator of status/trends, and the observed situation of stability cannot be said to be either in the BEA or that the situation is deteriorating as compared to the first assessment.
