Stock structure of Antarctic toothfish in Statistical Area 88 and implications for assessment and management
Abstract: We review the stock structure of Antarctic toothfish in Statistical Area 88 with the ... aim of characterising the likely stock boundaries relative to stock assessments. We include ... complex of SSRU 88.2H. Key information needs to further understand stock structure include characterising ... the movement patterns and linkages of Antarctic toothfish in the 80–120 cm size range, throughout the ...
