“…Although this analysis is largely descriptive, these types of VMS and habitat mapping exercises are useful for identifying potential relationships between fishing locations and ecosystem or environmental covariates (e.g., Cimino et al, 2019). It is expected that by elucidating these types of potential mechanistic relationships, population or fishery drivers will eventually be discovered, and insight will be provided for developing more refined dynamic spatial management (e.g., by identifying extraction hotspots or population components at risk of localized depletion; Maxwell et al, 2015;Birchenough et al, 2021). Additionally, the results provide tangible steps towards achieving a better mechanistic understanding of the production vs. attraction debate regarding the role of artificial structures, while also developing a useful management tool, which could be updated on a yearly basis, for identifying areas of high extraction that may warrant careful monitoring.…”

“…Recently, the implementation of Vessel Monitoring Systems (VMS), which provide regular Global Positioning System (GPS) coordinates of fishing vessel locations, have allowed analysis of fishing sites at extremely fine spatiotemporal scales (Gerritsen and Lordan, 2011). VMS data sets represent a rich resource that can help understand fishing dynamics, but the diversity of information that can be gleaned from analyzing them is still being discovered (Watson et al, 2018;Birchenough et al, 2021). A wide array of approaches exist for analyzing VMS data to discriminate steaming compared to fishing events, thus enabling the identification of spatially explicit fishing locations (O'Farrell et al, 2017;Muench et al, 2018).…”

“…Precise fishing sites can then be compared or simultaneously mapped with spatiotemporal distributions of oceanographic conditions, habitat maps, or biomass (Bueno-Pardo et al, 2017;Cimino et al, 2019). Thus, a more mechanistic understanding of factors driving fishing patterns can be uncovered, while also identifying spatiotemporal patterns in exploitation, essential fish habitat areas of concern, and potential operational oceanographic or habitat variables to aid in dynamic ocean management (Deng et al, 2005;Maxwell et al, 2015;Cimino et al, 2019;Birchenough et al, 2021).…”

Artificial Attraction: Linking Vessel Monitoring System and Habitat Data to Assess Commercial Exploitation on Artificial Structures in the Gulf of Mexico

Marine artificial structures provide important ecosystem benefits, but the extent to which commercially valuable reef fish species and their associated fisheries utilize artificial structures is still undetermined. However, the increasing implementation of onboard Vessel Monitoring Systems (VMS) now enables precise identification of catch and effort locations that can be linked via satellite coordinates to seafloor habitat maps. To better understand the distribution of fishing effort across artificial and natural reef types in the Gulf of Mexico, we present the first attempt to link VMS data from commercial reef fish vessels with high resolution habitat maps for an iconic species, red snapper (Lutjanus campechanus). By allocating landings from VMS-linked individual fishing trips to habitat type (i.e., natural reef, artificial structure, or uncharacterized bottom) and overlaying these with previously developed red snapper biomass distributions, we are able to develop one of the first fine-scale spatial maps of exploitation across the entire Gulf of Mexico. Results indicated that nearly half (46%) of commercial red snapper landings were extracted from artificial structures. The degree of exploitation was highly heterogeneous with several localized hotspots on natural reefs along the continental shelf break and offshore areas of the Northeast Gulf of Mexico. Similarly, there were distinct regional differences in fishing patterns: a majority of the landings from the state of Florida (∼91%) came from natural reefs, whereas ∼75% of landings were from artificial structures from all other Gulf of Mexico states combined. These results indicate that the potential for localized depletion exists for red snapper. The exploitation maps developed here can directly aid fisheries managers by highlighting specific habitats and locations that should be carefully monitored as catch limits continue to increase.

“…In the last two decades, new mandatory procedures evolved to improve and standardize fisheries data throughout the EU [6]. Large and more reliable datasets are generated, and statistical modelling can be applied to retrieve crucial fisheries information such as the identification of exploited species and their distribution [7][8][9]. The International Council for the Exploration of the Sea (ICES), the entity responsible for providing advice to the EU on fisheries issues, has identified, as a major objective in its Science Plan, the development of effective mechanisms to use monitoring and surveillance data to support scientific advice [10].…”

Time and spatial trends in landing per unit of effort as support to fisheries management in a multi-gear coastal fishery

et al. 2022

Landings by the multi-gear coastal fleet operating off the Portuguese continental coast include about 300 species, from which only a few are the object of management plans. In this study, daily landings (kg trip-1) are used, along with an effort indicator, vessel length overall (LoA), to obtain landings per unit of effort (LPUE) as a proxy for the species relative abundance, for a total of 48 species. LPUE indices were used as a response variable in linear models where year (2012–2016), season, region (north and south) and NAO index were explanatory variables. Seasonal and regional effects were found to significantly affect species abundance for a total of 41 and 40 species respectively, while year trends were found to be significant for 19 species, and the NAO index for 3 species. LPUE density maps are presented for several selected species and a subsample of trips, where VMS records were available. It is proposed that geographic and seasonal changes in LPUE can be used to understand trends in abundance and obtain information that can be used in support regional management plans.

Landings by the multi-gear coastal fleet operating off the Portuguese continental coast include near 300 species, from which only a few are the object of management plans. In this study, daily landings (kg trip _1 ) are used, along with an effort indicator, vessel length overall (LoA), to obtain landings per unit of effort (LPUE) as a proxy for the species relative abundance for a total of 48 species. LPUE indices were then used as a response variable in linear models where year (2012-2016), season, region (north and south) and NAO index were included as explanatory variables. Season and region effects were found to significantly affect species abundance for a total of 41 and 40 species respectively, while interannual effects were found to be significant for 19 species, and finally, the NAO index for 3 species. Global LPUE density maps are presented for a number of selected species and a subsample of trips where VMS records were available. For the species analysed, it is proposed that geographic and seasonal changes in LPUE indexes can be used to understand trends in abundance and obtain information that can be used in support of the definition of regional management plans.
