Deep-sea Chondrichthyans associated with the Patagonian toothfish Dissostichus eleginoides fishery off the coast of Peru

Revista de biologia marina y oceanografia, 2022
The deep-sea fishery for Patagonian toothfish (Dissostichus eleginoides) in Peru offers the opportunity to document species that may be new or rare to the region, or possibly new to science. Here, we report specimens caught, photographed and discarded in

Length-weight relationship of four deep-sea chondrichthyans (Elasmobranchii & Holocephali) in Ecuadorian oceanic waters

Egyptian Journal of Aquatic Research, 2022
The present work reported the length-weight relationship of four deep-sea chondrichthyan species (i.e., Hydrolagus spp., E. granulosus, C. owstonii and C.

Ecological risk assessment in the southern Indian Ocean: Towards better seabird bycatch mitigation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1218-1228, November 2023., 2023
Abstract Fisheries bycatch has been identified as the most serious threat to many seabird species and there is an increasing awareness of the responsibility of fisheries management bodies to include the impact on non‐target species in their management and regulatory frameworks. In 2022, an ecological risk assessment (ERA) for seabirds and fisheries was

Modal and empirical lengths at sexual maturity for six deep-sea species in Ecuadorian oceanic waters

Marine and Fishery Sciences, 2023
The objective of the present work was to establish modal lengths, empirical lengths at sexual maturity, and proportions of mature individuals of six deep-sea species from the bycatch of the experimental fishery for Patagonian toothfish (Dissostichus ...

The effect of prey abundance and fisheries on the survival, reproduction, and social structure of killer whales (Orcinus orca) at subantarctic Marion Island

Ecology and Evolution, Volume 13, Issue 6, June 2023., 2023
We tested whether the survival of killer whales (Orcinus orca) observed at Marion Island correlated with social structure and prey variables using multistate models of capture recapture data spanning 12 years. Survival was most strongly correlated with indices of social structure where higher sociality was associated with increased survival probability.

Guiding marine protected area network design with comparative phylogeography and population genomics: An exemplary case from the Southern Ocean

Diversity and Distributions, Volume 28, Issue 9, Page 1891-1907, September 2022., 2022
Abstract Aim Networks of connected marine protected areas (MPAn) are recognized as the key area‐based management tool to preserve biodiversity, moderate exploitation of marine resources and increase ecological resilience to climate change. Although population genetic studies could greatly benefit connectivity assessments between MPAs, genetic data are ...

Fisheries bycatch mitigation measures as an efficient tool for the conservation of seabird populations

Journal of Applied Ecology, Volume 59, Issue 7, Page 1674-1685, July 2022., 2022
We provide a holistic approach to assess the effects of management measures by analysing datasets from sampling methods commonly employed in seabird studies. Our conclusions should encourage the eradication of invasive predatory species in seabird breeding areas and the strengthening of bycatch mitigation measures for the vulnerable seabird species ...

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]

EFSA J
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

High‐resolution satellite imagery meets the challenge of monitoring remote marine protected areas in the Antarctic and beyond

Conservation Letters, Volume 15, Issue 4, July/August 2022., 2022
Abstract Remote, high‐latitude oceans can prove challenging for the designation and implementation of marine protected areas (MPAs), partly due to issues in monitoring inaccessible localities and large spatial scales. A lack of protection combined with damage from growing human activities has contributed to the degradation of some of the Earth's ...

Somatic energy content and histological analysis of the gonads in Antarctic fish from the Scotia Arc

Scientia Marina, 2005
Histological characteristics of the gonads and the energy contents of axial muscle, liver and gonads of Antarctic notothenioid fish collected during the LAMPOS (Latin American Polarstern Study) survey in April 2002 were analysed.
