Covid-19 pandemic has affected worldwide in many different ways. Fisheries around the world are not an exception due to long-term isolation and non-activities period suffered. To do evaluation of its impact on fishing sectors Canary Islands, 87 online phone questionnaires were carried out between July September 2020, conducting interviews artisanal fishermen, fishmongers, recreational charter boats fishermen tackle shops along archipelago. Both, have been by this pandemic, but unequal...
The presence of spiny butterfly rays, Gymnura altavela, in waters less than 20 m deep off the Canary Islands shows marked seasonality, with relatively high abundances summer and autumn. Large aggregations sometimes hundreds individuals, primarily females, appear specific shallow areas archipelago seem to be associated seasonal variation water temperature. This pattern or absence suggests that rays migrate into deeper other unknown during rest year. G. altavela sexual dimorphism; our study,...
Abstract This is the first study addressing validation of early growth stages (including increment) in beaks juvenile cuttlefishes. The age juveniles Sepia officinalis was performed by comparison number increments observed rostrum surface lower jaws with their true age. A total 159 individuals were reared at 18 ºC and 21 ºC, ages up to 31 days from hatching. beak counted contrasted life after hatching, validating hypothesis one increment corresponding day life. mean coefficient variation...
Percnon gibbesi is a native crab species characteristic of intertidal and subtidal zones the Atlantic coast European Macaronesian archipelagos (Azores, Madeira, Canary Islands), probably also in neighbouring rocky coasts northwest Africa. P. considered an invasive alien almost all Mediterranean, with expanding populations from Spain to Turkey, including Libya. However, its biology ecology are highly unknown, despite range distribution. In Gran Canaria Island, this crab, shows carapace length...
Abstract In this study, we explored the feasibility of using beaks African cuttlefish Sepia bertheloti for age estimation and growth analysis. The rostrum sagittal section (RSS) lower beak was most suitable region in species. It applied samples caught off Morocco Guinea-Bissau between June 2018 January 2020. A maximum life expectancy around 14 months observed (specifically 419 days cuttlefishes from 433 Guinea-Bissau). males presented greater longevity, as females 9 11 months. showed a...
In this paper we consider what may happen to the marine ecosystem of Gran Canaria Island within 2030 horizon, if fishing strategies different from those currently in place were implemented and evaluate effect of, for example, reduction recreational-artisanal fishing, limitation catches (e.g. total allowable catches, TAC), or spatial distribution sectors. From all scenarios tested, only that significantly reduce high effort recreational would allow recovery most exploited stocks short...
Abstract We report the first case of partial albinism in Critically Endangered angelshark, Squatina squatina . The encounter with this specimen took place while SCUBA diving on beach Tufia, located east coast island Gran Canaria 2 April 2021. This is also confirmed finding an albino elasmobranch Canary Island archipelago.
Length-weight relationships (LWRs) were estimated for 15 mesopelagic shrimp species off the Canary Islands (central eastern Atlantic). Total length, cephalothorax length and total weight taken individuals collected during three research campaigns using a commercial semi-pelagic trawl net. The most represented families among Sergestidae Oplophoridae, with eight species, respectively. Overall, 60% of showed isometric growth, 33.3% negative allometry 6.7% positive allometry. These LWRs are...

The African cuttlefish, Sepia bertheloti, is a commercially exploited cephalopod in two productive system areas off West Africa. However, there lack of information on its feeding ecology, making it difficult to describe ecological role (Morocco and Guinea-Bissau). In the present study, we analyse gastric contents 1.114 individuals, collected between July 2018 January 2020 using traditional analysis stomach contents. A total 65 49 prey items were identified as part diet Moroccan Guinean...
