We would like to check if you have information pertaining to the taxonomy, biology, distribution, degree of exposure to threatening processes, levels of fishing effort, and species population trends. We understand species-specific data are lacking for most species, so we aim to infer or suspect population changes from the best available information on levels of fishing pressure. We would also appreciate any details on the fisheries that interact with the species in the above list; time-series of population data, general catch and effort trends, data on how individual species ranges overlap with fisheries (this includes both quantitative and qualitative data). If you have any information that can contribute to these assessments and are interested in being involved, we would like to hear from you. Based on the information you have for each species, please only contact the lead person as mentioned in the table. - Dr Rima Jabado | rimajabado@iucnssg.com - Dr Brit Finucci | brit.finucci@niwa.co.nz - Dr Samm Sherman | samm_sherman@sfu.ca - Dr Fabrizio Serena | fabrizio50serena@gmail.com - Dr Sophy Phillips | sophy.phillips@cefas.co.uk Please submit any information you have as soon as possible. Completed assessments will be sent for review by early March 2022. Your level of involvement can range from contributing information to being closely involved as an assessor. To be considered as an Assessor, we will ask you to complete the online IUCN Red List training course Modules 1-4 at Online IUCN Red List Training (see details below). If you are interested in being involved in IUCN Red List assessments or would like more information on the assessment process or online training courses, please contact Dr Cassie Rigby, the SSG Red List Authority Coordinator and Assess Working Group Chair at CassandraRigby@IUCNSSG.com.
