Calls upon all States, directly or through regional fisheries management organizations and arrangements, to apply stock-specific target and limit precautionary reference points, which for target reference points are intended to meet management objectives, as described in annex II to the Agreement and in the Code, to ensure that populations of harvested stocks and, where necessary, associated or dependent species, are maintained at or restored to s ustainable levels, and to use these reference points for triggering conservation and management action; 13. Encourages States, directly or through regional fisheries management organizations and arrangements, to establish and implement rebuilding and reco very strategies and plans where a stock is identified as being overfished, which should include time frames and probabilities of recovery aimed at bringing the stock back at least to levels that can produce the maximum sustainable yield, and guided by scientific assessment and subjected to periodic evaluation of progress; 14. Also encourages States to apply the precautionary approach and ecosystem approaches in adopting and implementing conservation and management measures addressing, inter alia, by-catch, pollution and overfishing, and protecting habitats of specific concern, taking into account existing guidelines developed by the Food and Agriculture Organization of the United Nations; 15. Further encourages States to enhance or develop observer programmes, individually or through regional fisheries management organizations or arrangements, in order to improve data collection on, inter alia, target and by -catch species, which could also assist monitoring, control and surveillance tools, and to take into account standards, forms of cooperation and other existing structures for such programmes as described in article 25 of the Agreement and article 5 of the Code; 16. Calls upon in this regard States, individually in line with their national legislation or through regional fisheries management organizations or arrangements, to take steps as appropriate to ensure the safety of observers; 17. Encourages States to implement, individually and through regional fisheries management organizations and arrangements, accurate, complete, reliable and effective data collection and reporting of required data on catches, including by catch and discards, reviewing and validating the data, and providing catch information in support of scientific stock assessment and ecosyst em approaches to fisheries management; 18. Calls upon States and regional fisheries management organizations and arrangements to collect and, where appropriate, report to the Food and Agriculture Organization of the United Nations required catch and effort data, and fisheryrelated information, in a complete, accurate and timely way, including for straddling fish stocks and highly migratory fish stocks within and beyond areas under national jurisdiction, discrete high seas fish stocks, and by-catch and discards; and, where they do not exist, to establish processes to strengthen data collection and reporting by members of regional fisheries management organizations and arrangements, including through regular reviews of member compliance with such obligations , and, when such obligations are not met, require the member concerned to rectify the problem, including through the preparation of plans of action with timelines; 19.
