Evaluating the suitability of close‐kin mark‐recapture as a demographic modelling tool for a critically endangered elasmobranch population
Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history.

Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history. For benthic elasmobranchs such as skates, traditional fisheries‐independent approaches are often unsuitable as the data may be subject to various sources of bias, whilst low recapture rates can render mark‐recapture programmes ineffectual. Close‐kin mark‐recapture (CKMR), a novel demographic modelling approach based on the genetic identification of close relatives within a sample, represents a promising alternative approach as it does not require physical recaptures. We evaluated the suitability of CKMR as a demographic modelling tool for the critically endangered blue skate (Dipturus batis) in the Celtic Sea using samples collected during fisheries‐dependent trammel‐net surveys that ran from 2011 to 2017. We identified three full‐sibling and 16 half‐sibling pairs among 662 skates, which were genotyped across 6291 genome‐wide single nucleotide polymorphisms, 15 of which were cross‐cohort half‐sibling pairs that were included in a CKMR model.
