    Despite the popularity of elasmobranchs in zoos and aquariums, data on hematological values for health monitoring remain limited, particularly for wild populations. In this study, reference intervals for key hematological parameters and blood pH were established from blood samples of 49 adult females of the Critically Endangered Spiny Butterfly Ray (Gymnura altavela) collected across three shallow beaches in the Canary Islands. Additional data were obtained from four adults maintained under human care. To our knowledge, this is the first report of hematological and blood pH reference intervals for free-ranging G. altavela. Lymphocytes (56%) were the dominant leukocyte, followed by heterophils (23.6%), eosinophils (16.7%), monocytes (2%), neutrophils (1.1%), and basophils (0.2%). Median values included 356.6 $$\times$$ 10$$^{\text {3}}$$ cells/$$\upmu$$L for red blood cell count (RBC), 31.7 $$\times$$ 10$$^{\text {3}}$$ cells/$$\upmu$$L for white blood cell count (WBC), 28.2% for packed cell volume (PCV), and 8.1 g/dL for total plasma solids (TS). Blood pH averaged 7.25, rising to 7.38 with temperature correction. These values remained consistent across reproductive states and housing conditions, suggesting minimal physiological disruption. This study highlights the effectiveness of rapid, low-stress sampling and provides essential baseline data to support veterinary care and conservation strategies for G. altavela. Expanding future research with a larger sample size will enhance understanding of health variations by age, sex, and reproductive status.
  • Influence of climate variability and shark interactions on artisanal deep-water fisheries in Spain's largest marine reserve
    David Jiménez-Alvarado, Ana Espino-Ruano, Airam Guerra-Marrero, Julián Cabana-Gandiaga, Tomas Bañeras, José J. Castro-Hernández, Lorena Couce-Montero
    Marine Environmental Research, 2026
    Artisanal fisheries in the Canary Islands are an essential element of local livelihoods but face increasing challenges due to climate variability, access restrictions due incompatibility with other marine activities (i.e. wind farm and aquaculture), and resource depletion. Moreover, in recent years, fishers operating in the deep-water artisanal fishery of northern Lanzarote reported significant declines in catches, attributing up to 30% of losses to shark depredation on their captures while hoisting. We combined fisher surveys (n = 26), onboard monitoring trips (between 2022 and 2023), and time-series analyses of landings (2006-2023) to evaluate the magnitude of this stealing sharks interactions and their ecological context. Survey data indicated frequent shark encounters, mostly involving shortfin mako (Isurus oxyrinchus), thresher sharks (Alopias spp.), and hammerhead sharks (Sphyrna spp.). However, direct observations during 317 monitored fishing sets recorded only two possible shark-related losses, representing just 0.7% of total fishing effort. By contrast, wavelet analyses of landing series revealed strong correlations between the North Atlantic Oscillation (NAO) and catch variability, with 8-18 month lags. Periods of negative NAO (2014-2017) coincided with exceptional recruitment of deep-water fish species and subsequent record catches between 2018 and 2020, followed by sharp declines after 2021. Our findings suggest that catch losses by stealing sharks, although occasionally perceived as severe by fishers, exerts only a minor direct effect on catches. Instead, climate-driven fluctuations in recruitment and stock availability largely explain observed trends. These results underscore the importance of incorporating climate indices into fisheries assessments and management, while continuing to monitor shark-fishery interactions given their potential socioeconomic implications.
  • Unintended evolutionary consequences of a minimum landing size regulations: Evidence and implications of fisheries-induced evolution

    Plos One, 2026
    A total of 725 historical photographs taken between 1940–2022 were analysed to assess the temporal variations in target species and the size-frequency distribution of recreational fishing catches in the Canary Islands. A significant shift from predominantly single-species fishing to a more diverse, multispecies approach was observed, particularly since 2000. Species such as Dentex gibbosus , Diplodus cadenati , Epinephelus marginatus , Lithognathus mormyrus , and Sparisoma cretense showed consistent size reductions over the decades. The analysis revealed discrepancies between current Minimum Landing Sizes (MLS) in the Canary Islands and the lengths at which these species reach sexual maturity (L50), or the length at which 50% of fish are mature. Except for Diplodus cadenati , the MLS for the examined species are smaller than their respective L50 values, indicating that individuals are often harvested before reproducing. The use of the L50 as a standard for reference length can trigger a fisheries-induced evolution. This occurs because the extractive activities resulting from this standard promote reduced fish size and earlier maturation, which could lead to lasting evolutionary changes in fish communities. Our study underscores the need to reevaluate minimum landing size (MLS) regulations and seek a transition towards L95, to ensure they are aligned with the reproductive biology of target species, thereby promoting sustainable fishing practices and the conservation of marine biodiversity in the Canary Islands. Even so, this proposed improvement and the results of this study should be combined with a Harvest-slot length limits (based on species-specific ecological and demographic studies) to ensure the survival of megaspawners.
  • Fisheries ecological knowledge, FEK: Contribution to the knowledge of the ecology and distribution of houndsharks and dogfish shark (family Triakidae and Squalidae) in the Canary Islands

    Plos One, 2026
    Currently, it is assumed that most of elasmobranchs (sharks, rays and skates) had suffered a high depletion in their populations worldwide, but there is an important lack of biological and fishing information over the bulk of the species that do not permit to determine the real status of their populations. Seven of these scarce information species are the houndsharks and dogfish shark (family Triakidae and Squalidae) found in the Canary Islands, which actual status level and contribution to the catch in the archipelago are still unknown. 136 interviews were carried out among artisanal fishers from all the islands, in which very few of them were able to distinguish all the species. Two houndshark and one dogfish shark species were frequently identified and/or caught (the common smoothhound ( Mustelus mustelus ), the tope shark ( Galeorhinus galeus ) , and the shortnose spurdog ( Squalus megalops )), and half of the fishers were not able to distinguish the sex of these fishes. The houndsharks and dogfish shark are preferentially distributed down to 200 metres depth, with higher catches off the eastern and central islands. These sharks are caught all year round with highest peaks during the summer months, probably coinciding with aggregations for mating and reproduction in shallower waters. Houndsharks and dogfish shark are generally not targeted by artisanal fisheries and, although sometimes landed, most of the catch is usually discarded. Sharks caught range from 100 to 120 cm in total length for common smoothhound and tope sharks, while the catch size for shortnose spurdog varies between 50 and 60 cm in total length. Improving taxonomic knowledge within the fishing sector is essential for sustainable management and conservation of houndshark and dogfish shark species in Canarian waters.

    Ecological Solutions and Evidence, 2026
    Challenge : The depletion of elasmobranch populations and limited access to these species have posed significant challenges for researchers aiming to study sharks and rays effectively. Response : Consequently, novel techniques have been developed to enhance knowledge of these species within the marine environment. Target species : Our focus has been on the spiny butterfly ray, a benthic species that spends portions of its life cycle near the coast in shallow areas. Methodology : Between 2020 and 2024, 133 individuals of spiny butterfly ray were internally tagged in Gran Canaria and Tenerife using a combined double tagging approach, employing acoustic and external T‐bar tags. Additional data collection : During the same procedures, skin, gill, and anal orifice swabs were obtained to analyse microbiota; blood samples were collected to assess stress levels and hormonal profiles; and in situ ultrasound examinations on females were performed to evaluate pregnancy status. Morphometric measurements were also recorded for future growth and age studies. Operational efficiency : All these processes were conducted simultaneously through coordinated efforts among sub‐teams, enabling the complete methodology to be completed in less than 8 min per individual. Practical implication : Solution : This integrated, rapid approach demonstrates an effective model for minimally invasive, multifaceted research on elusive benthic elasmobranchs, potentially informing conservation strategies and further ecological understanding.
  • Population structure and life history parameters of the broad-clawed porcelain crab Porcellana platycheles (Pennant, 1777) (Decapoda: Anomura: Porcellanidae) in the intertidal zone of Gran Canaria, Canary Islands, Spain
    Pietro Arnosti, Airam Guerra-Marrero, Lorena Couce-Montero, David Jiménez-Alvarado, Ana Espino-Ruano, José J Castro
    Journal of Crustacean Biology, 2025
    The size of individuals of the intertidal broad-clawed porcelain crab (Porcellana platycheles (Pennant, 1777)) shows great variability on the island of Gran Canaria, Canary Islands, Spain, with individuals significatively larger in the north than in the south of the island. Males showed higher carapace length and width as well as weight than females. Females predominated over males, with a sex ratio of 1:1.5. Ovigerous females were observed only from November to April, with a peak of abundance in January and a secondary one in April. The growth pattern of crabs varied from positive allometric (north and eastern coasts) to isometric (southern coast). Both sexes also showed different growth patterns, being positive allometric in males, negative allometric to isometric in females.

    Accurate species identification is crucial for effective fisheries management, particularly for cryptic species with overlapping ranges and similar morphologies. This study explores the coexistence and distribution of Aphanopus carbo and Aphanopus intermedius in the northeastern Atlantic over four decades using otolith contour analysis. Otolith samples were collected from Madeira and the African coast between 1990 and 2021 and analyzed using a wavelet-based method, which improves species discrimination by capturing finer morphological details. The analysis revealed stable species proportions over time, with A. carbo generally dominating the catches (~55–60%), except in 2010 when a decline was observed. A higher presence of A. intermedius in offshore areas may be associated with increased salinity near Madeira Island during the spawning season (October–December). Environmental changes, including variations in temperature and salinity at depths greater than 800 m, and the progressive expansion of the drifting longline fishery to new grounds, likely influenced these patterns. This study demonstrates that combining otolith contour analysis with genetically identified reference specimens enhances species discrimination and provides valuable insights into population dynamics and habitat use. These findings contribute to more effective fisheries management and stock assessments for these economically important scabbardfish in the northeastern Atlantic.
  • Distinct management units for the Critically Endangered angelshark (Squatina squatina) revealed in the Canary Islands

Feldheim
    Conservation Genetics, 2025
    The angelshark, Squatina squatina , is listed as Critically Endangered on the IUCN Red List of Threatened Species, and remaining populations are highly fragmented throughout its historical distribution. The Canary Islands archipelago in the North East Atlantic has been identified as a uniquely large stronghold for the species. In the present study, we compared the population genetic structure of S. squatina across different islands of the Canary Island archipelago using both microsatellite and single nucleotide polymorphism (SNP) markers. Both markers revealed significant differentiation of angelsharks between islands in the archipelago, with three main genetic units at: (1) Tenerife, (2) Gran Canaria and (3) the island group consisting of La Graciosa, Lanzarote and Fuerteventura. Our results imply a connectivity barrier between some adjacent islands, most likely driven by abyssal depths, and varying geological history and formation of each island and oceanographic patterns (i.e. seasonal coastal upwellings off the African coast). Therefore, we suggest that in the Canary Islands, S. squatina populations should be managed locally, with conservation and research priorities designed and implemented specifically for each of the three genetic units.
  • Addressing offshore wind farms compatibilities and conflicts with marine conservation through the application of modelled benchmarking scenarios
    L. Couce Montero, A. Abramic, A. Guerra Marrero, A. Espino Ruano, D. Jiménez Alvarado, José J. Castro Hernández
    Renewable and Sustainable Energy Reviews, 2025
    Offshore wind power generation structures are scheduled for development in the Canary Islands, potentially resulting in spatial overlap with various maritime activities, particularly fishing. It is crucial to point out that some areas that are considered suitable for installing these structures are in protected zones that are part of the Natura 2000 network, and do not have any prior environmental impact assessments. The research delved into the efficacy of utilizing Ecopath with Ecosim software to examine the consequences of implementing this technology in the study area, employing an ecosystem-based approach. To address this question, simulations were executed by assessing three distinct scenarios. The results suggest that there would be changes in the distribution of keystone species such as top predators, alongside a conspicuous decline in the abundance and catches of target species of the fishery. The Ecospace model holds the potential to forecast the impacts of offshore wind installations; however, crucial factors must be carefully considered, such as the lack of information. Notwithstanding the constraints, research like this demonstrates the efficacy of spatial ecosystem modelling in exploring this issue. • Ecosystem model could be a useful tool to investigate impacts of offshore wind energy. • Potential conflicts between offshore wind farm and fishing were evaluated. • The development of offshore wind energy could affect keystone species. • Addressing data gaps will reduce model uncertainty and allow accurate estimates.
