“…cat/ en/ ), overseeing both recreational and commercial fishing activities along the Catalan coast (ICATMAR, 2023). This monthly monitoring, using methods such as experimental trawling surveys or non-invasive technologies like ROV surveys and robust experimental designs such as before-after-control-impact (Tuset et al, 2021;Vigo, Navarro, Aguzzi, et al, 2023;, could provide data that allow periodical estimates of the effectiveness' of both permanent and temporal closures and the uptake of adaptive management actions when necessary. An ecosystem-based approach could be adopted when monitoring changes in biomass and species abundance over time, including seasonal or long-term fluctuations in predator densities that may impact the abundance of other species.…”

“…Spatial closures, such as Marine Protected Areas (MPAs), have often proved to be an effective measure for restoring overexploited fishery stocks and protecting biodiversity (Abesamis & Russ, 2005;Di Franco et al, 2016;Giakoumi et al, 2017). Empirical evidence clearly shows that the density, biomass and individual body size of overexploited species increase in well-enforced and effective MPAs, especially in no-take marine reserves where all extractive uses are banned (Linares et al, 2012;Sala & Giakoumi, 2018;Vigo, Navarro, Aguzzi, et al, 2023;. An example of the benefits of MPAs to fisheries occurs when the biomass enhanced inside the reserve is exported beyond the protected boundaries, engendered by the dispersal of adults, larvae or eggs outward from the MPA (Di Lorenzo et al, 2020;Manel et al, 2019;Marshall et al, 2019).…”

The increasing global demand for marine resources raises concerns about sustainable resource management and biodiversity conservation. Spatial closures, such as marine protected areas, can be valuable tools for maintaining and restoring exploited populations. When these spatial closures adopt a dynamic nature being adapted to the changing environment, they can effectively account for factors such as shifting species distributions, which enhances their potential to achieve ecological and socio‐economic objectives. Here, we adapted a decision‐support tool (the software Marxan), typically used for selecting static and permanent areas, to produce management recommendations that integrate permanent and temporal closures to fisheries. Our aim was to compare the outputs of a static network of permanent no‐take reserves with four other dynamic scenarios, including permanent and temporal closures that account for seasonal variations in the populations of species. All scenarios prioritized sites for the conservation of one of the most valuable European fishing stocks, the Norway lobster (Nephrops norvegicus). Additionally, we considered 12 other commercially exploited species captured by the Norway lobster fishery. The assessed outputs included retained biomass, area extent, closure type (permanent and seasonal) and opportunity costs within each scenario. We observed that all dynamic scenarios required fewer management areas permanently closed than the static scenario. This resulted in a lower opportunity cost for fisheries but also a higher capacity for biodiversity conservation. Therefore, complementing permanent with temporal closures could enhance biodiversity conservation and fisheries management. The novel dynamic planning method presented here could be applicable to other species, ecosystems and socio‐economic contexts.

Bottom trawling developed from the practice of fishing with a net or long lines, but that older style was able to be more controlled and discriminate in its catch. With bottom trawling, nets are weighted to keep them low along the seafloor and a large beam on deck spreads nets wide to increase catch. Marine biologists and environmentalists have been concerned about trawling since it began. As far back as 1376, the English parliament highlighted the destructive nature of the practice to fish populations and habitats, noting that it ‘runs so heavily and hardly over the ground when fishing that it destroys the flowers of the land’ and takes so many fish ‘to the great damage of the commons and the destruction of the fisheries’ (Petition by the Commons to King Edward III, 1376 seen in Bolster, 2012). This first known mention of trawling calls for the removal of the practice and yet the activity endures. Trawling in Europe continued sporadically through the medieval and early modern periods using mainly the beam trawl method until the early nineteenth century when the industrial revolution pushed the technology further.

Quantification of Bottom Trawl Damage to Ancient Shipwrecks: A Case Study from the Coastal Waters of Turkey

Ancient shipwrecks in the Mediterranean region are particularly susceptible to damage by bottom trawl fishing activities because of their low relief on the seabed. Shipwrecks from the Greek and Roman periods typically consist of mounds of amphora cargoes, which slump onto the seabed in the shape of the vessel outline once the wooden hulls deteriorate following consumption by wood boring organisms. These low relief mounds do not snag trawl nets the way steel-hulled shipwrecks do in which fishers lose gear and could avoid those locations later. Instead, the fragile ceramic artefacts that comprise ancient wrecks are exposed to repeated strikes by trawls until they are broken and scattered across the seabed, potentially to the extent that they can no longer be found. Expeditions from 2008 through 2013 by Ocean Exploration Trust (OET) and the Exploration Vessel Nautilus documented numerous ancient shipwrecks in the Black and Aegean Sea coastal waters of Turkey that exhibited a range of damage from trawls, and which allowed for quantification of some of this damage.
