The objective of WKFISHDISH2 was to develop a standardized and open-source way of routinely using trawl survey data to produce distribution maps which can be easily updated. To do so, workshop participants (i) reviewed models that can produce distribution maps from survey data in DATRAS and MEDITS formats, (ii) considered best practice guidance for...

Marine Protected Areas (MPAs) are a promising management tool for the conservation and recovery of marine ecosystems, as well as fisheries management. MPAs are generally established as permanent closures but marine systems are dynamic, which has generated debate in favour of more dynamic designs. As a consequence, the identification of priority are...

The common sole (Solea solea) is a species of flatfish of great commercial relevance in the northern Atlantic Iberian waters. Although many studies investigated the early life-stage of this species, little is known on the adult phases and the size structure of the population. Here we provide an analysis of the spatiotemporal distribution of adult’s...

In this work, we discuss the use of a methodological approach for modelling spatial relationships among species by means of a Bayesian spatial coregionalized model. Inference and prediction is performed using the integrated nested Laplace approximation methodology to reduce the computational burden. We illustrate the performance of the coregionaliz...

Fishery restricted areas (FRAs) are pivotal for the mitigation of fishery impacts, but the designation of optimum FRAs is complex, and currently there is no quantitative guideline to assess the spatio-temporal variability of conservation priority areas. Fishery systems are naturally dynamic, and shifts may at two different levels, the species level...

The protection of fish nurseries has been recognized as a useful tool to efficiently manage fisheries given that protected areas enhance the recruitment of target species. To identify and locate potential nursery areas, a solid understanding of species-environment relationships and their spatio-temporal dynamics is needed. Within this context, in t...

Understanding the spatiotemporal persistence of fish distributions is key to defining fish hotspots and effective fisheries restricted areas (FRAs). Hierarchical Bayesian spatiotemporal models provide an excellent framework to understand these distributions as they can accommodate different spatiotemporal behaviour in the data, primarily due to the...

As Uhlman et al. (2014) say, discard rates are highly variable at European level and are more heterogeneous across regions than in different fisheries. Therefore, it is known that there are variations at the regional level, but it is unknown if these differences are given to Mesoscale, in a radius of approximately 200km. The objective of the presen...

Species Distribution Models (SDMs) are now being widely used in ecology for management and conservation purposes across terrestrial, freshwater, and marine realms. The increasing interest in SDMs has drawn the attention of ecologists to spatial models and, in particular, to geostatistical models, which are used to associate observations of species...

A sensible approach to minimize discards is to avoid areas or seasons where unwanted catch may be present. The implementation of a Marine Spatial Planning (MSP) approach to discard management requires the understanding of marine biological processes, as well as fishing conditions at a defined spatial scale. Mathematical models that analyze the spat...

This study compared different spatio-temporal model structures to infer the distributional patterns of Mullus barbatus in the GSA06 of the Spanish Mediterranean using MEDITS trawl survey data, whic is performed every year in spring. Results indicate that Mullus barbatus follows a very persistent distribution at this time of the year.

This study compared different spatio-temporal model structures to infer the distributional patterns of Lophius budegassa the GSA06 of the Spanish Mediterranean using MEDITS trawl survey data, which is performed every year in spring. Results indicate that Lophius budegassa follows a rather opportunistic distribution at this time of the year.

This study compared different spatio-temporal model structures to infer the distributional patterns of Illex coindetii in the GSA06 of the Spanish Mediterranean using MEDITS trawl survey data, whic is performed every year in spring. Results indicate that Illex coindetii follows a rather opportunistic distribution at this time of the year.

This study compared different spatio-temporal model structures to infer the distributional patterns of Merluccius merluccius the GSA06 of the Spanish Mediterranean using MEDITS trawl survey data, whic is performed every year in spring. Results indicate that Merluccius merluccius follows a progressive distribution, with certain persistence, at this...

This study compared different spatio-temporal model structures to infer the distributional patterns of Lophius piscatorius the GSA06 of the Spanish Mediterranean using MEDITS trawl survey data, which is performed every year in spring. Results indicate that Lophius piscatorius follows a opportunistic distribution at this time of the year.

Many ecological processes are measured as proportions and are spatially sampled. In all these cases the standard procedure has long been the transformation of proportional data with the arcsine square root or logit transformation, without considering the spatial correlation in any way. This paper presents a robust regression model to analyse this k...

Understanding the spatio-temporal dynamism and environmental relationships of species is essential for the conservation of natural resources. Many spatio-temporally sampled processes result in continuous positive [0, ∞) abundance datasets that have many zero values observed in areas that lie outside their optimum niche. In such cases the most commo...

Atlantic bluefin tuna, managed by the International Commission for the Conservation of Atlantic Tunas (ICCAT), is a top predator emblematic species with a key role in marine ecosystems. In spring bluefin tuna adults travel a long distance to reproduce in very confined areas such as the Balearic Sea, a major spawning ground worldwide located in the...

The spatial management of fisheries has been repeatedly proposed as a discard mitigation measure. A number of studies have assessed the fishing suitability of an area based on units of by-catch or discard per unit effort. However, correct identification of fishing-suitable areas should assess biomass loss with respect to the benefits. This study th...

Spatial and temporal closures of fish nurseries have recently been recognized as useful tools for an efficient fisheries management, as they preserve the reproductive potential of populations and increase the recruitment of target species. In order to identify and locate potential spatio-temporal closures, a solid knowledge of species-environment r...
