Here we provide a progress update on the Antarctic toothfish genetic connectivity project (WS-DmPH-18/08). A total of 4237 tissue samples have been made available for this project from nine CCAMLR members with the vast majority of these collected during the 2017/18 season. Of the planned 550 sample sequences, DNA has been extracted so far from 473 samples with 304 samples containing sufficient quality and quantity to be sequenced. Genotype data has initially been collected from 90 samples using high throughput sequencing methods (DArTseq™ technology). We also make recommendations for future sample collections of Antarctic toothfish and recommend the CCAMLR data warehouse develops sample data storing capability to allow for better links between individual samples and corresponding data.
