Feeding Relationship between Octopus vulgaris (Cuvier, 1797) Early Life-Cycle S...
Lourenço, Sílvia; Roura, Álvaro; Fernández-Reiriz, María-José; Narciso, Luís; González, Ángel F.Under the influence of the Western Iberian upwelling system, the Iberian Atlantic coast holds important hatcheries and recruitment areas for Octopus vulgaris. Recently identified as an octopus hatchery, the Ría de Vigo harbors an important mesozooplankton community that supports O. vulgaris paralarvae during the first days of their planktonic stage. This study represents a preliminary approach to determine the ...
Spawning habitat selection by the common cuttlefish Sepia officinalis in the Cí...
Guerra, Ángel; Hernández-Urcera, Jorge; Garci, Manuel E.; Sestelo, Marta; Regueira, Marcos; Gilcoto, Miguel; González, Ángel F.We evaluated specific habitat features (bottom substrate type, depth, temperature, season and latitude- longitude) at random locations in the Cíes Islands (Galician Atlantic Islands National Park, Northwest Spain) to determine their impact on Sepia officinalis spawning habitat use. We performed underwater visual transects via scuba diving. In total, 94 transects were conducted between April 30, 2012 and July 17...
Spawning habitat selection by Octopus vulgaris: new insights for a more effecti...
Guerra, Ángel; Hernández-Urcera, Jorge; Garci, Manuel E.; Sestelo, Marta; Regueira, Marcos; González, Ángel F.; Cabanellas-Reboredo, MiguelThe selection of spawning habitat of a population of Octopus vulgaris that is subject to a small-scale exploitation was studied in the Cíes Islands within the National Park of the Atlantic Islands of Galicia (NW Spain). The technique used was visual censuses by scuba diving. We conducted 93 visual censuses from April 2012 to April 2014. The total swept area was 123.69 ha. Habitat features (season, depth, zone, ...
Stylet (vestigial shell) size in Octopus vulgaris (Cephalopoda) hatchlings used...
Lourenço, Sílvia; Moreno, Ana; Narciso, Luís; Pereira, João; Rosa, Rui; González, Ángel F.The estimation of age and growth of cephalopod stocks is a key issue for their sustainable management. Recently, several studies have successfully validated the daily deposition of growth rings in the vestigial shell or stylets of several octopus species. Octopus vulgaris eggs were incubated at two different temperatures, 18 and 22ºC, until hatching to determine stylet size at hatching and assess the effect of ...
Optimization of the pepsin digestion method for anisakids inspection in the fis...
Llarena-Reino, María; Piñeiro, Carmen; Antonio, José; Outeriño, Luis; Vello, Carlos; González, Ángel F.; Pascual, SantiagoDuring the last 50 years human anisakiasis has been rising while parasites have increased their prevalence at determined fisheries becoming an emergent major public health problem. Although artificial enzymatic digestion procedure by CODEX (STAN 244-2004: standard for salted Atlantic herring and salted sprat) is the recommended protocol for anisakids inspection, no international agreement has been achieved in v...
The accuracy of visual inspection for preventing risk of Anisakis spp. infectio...
Llarena-Reino, María; González, Ángel F.; Vello, Carlos; Outeiriño, Luis; Pascual, SantiagoThe importance of the zoonoses caused by L3 Anisakidae larvae lies in the repercussion that this parasite exerts on food safety and quality. EU legislation recommends fish operators to do visual inspection of the whole fish abdominal cavity and gut to control the risk of visible parasites, thus ensuring that no contaminated fish reach the consumers. The accuracy of the above visual inspection method should fall...
