Analysis of Ecological Risk Assessment (ERA) of deepwater chondrichthyan species has shown there is a low degree of overlap between the FAO, IUCN and aquamaps mapping sources for many deepwater chondrichthyans. The analysis also showed that many species have been shown to be caught outside their known distributions by SIOFA fisheries. More precise distribution maps are required for future ERA analyses. 

Update the stock assessment of Alfonsino stocks in the SIOFA area. This should build on and improve the work of the previous assessment (Brandão et al. 2020). The outcomes of this assessment should be collated in a report and presented to SC11 in 2026.

The SIODFA data archive covers information and data relating to SIODFA activities in the SIOFA Area for the period 1999 to date. It constitutes over two Gigabytes of information that includes 1040 folders, 6000 individual documents and data files, and image files. A small number of reports are available in hard copy only and would, if required, need to be digitised.

This project aims to contribute to the post-processing of benthic macro-invertebrate by-catch images and underwater imagery collected during survey leg 3.3 (Deep-sea fisheries resources in the SIOFA Convention Area) conducted aboard the R/V Dr Fridtjof Nansen under the FAO EAF-Nansen Programme and the Common Oceans Deep-sea Fisheries Project. The mission generated an integrated dataset combining trawl bycatch sampling, van Veen grab sediment sampling, and deep-sea video observations across key seamount systems (Walter’s Shoal, Station X, Banana) (see paper SC-11-52).
