The Role Of Market Trends In Sustainable Fisheries And Marine Ecosystem Conservation – In 2019, the proportion of fisheries at biologically sustainable levels dropped to 64.6%, a decrease of 1.2 percentage points from 2017 (Figure 23). The score was 1974, which was 90%. By comparison, since the late 1970s, the proportion of groups living at biologically unsustainable levels has increased from 10% in 1974 to 35.4% in 2019. And keep at it. Biosustainable stocks accounted for 82.5% of assessed stocks in 2019.
Biosustainable stocks accounted for 57.3% and 7.2% of the total assessed stocks in 2019, respectively, which includes both sustainable and non-sustainable stocks. and 2019), although the maximum sustainable catch declined between 1974 and 1989 and subsequently increased to 57.3% in 2019. %) of stocks for the year were at unsustainable levels, followed by the Mediterranean and Black Sea (zone 37) with 63.4% (Figure 24). In comparison, the Northeast Pacific (Area 67), the East-Central Pacific (Area 77), the West-Central Pacific (Area 71) and the Southwest Pacific (Area 81) have the lowest proportions of fish at biologically unsustainable levels (13-23%). . In 2019, the share in other regions varied between 27% and 45% (Figure 24). Fish landings vary widely among fishing areas (Fig. 9b), so the importance of each area to the sustainability of global fisheries is likely to vary based on its relative contribution to global landings. , fishery development level, management and fishery resource status. Overall, excluding the Arctic and Antarctic regions with the least settlement, three population patterns can be observed (Figure 25): (i) areas showing an overall downward trend after the historical peak; (ii) cage areas since 1990 has been fluctuating around the global stable value since 1950, which is related to the dominance of pelagic, short-lived species; (iii) since 1950. An area that has continued to grow ever since. The first group has the lowest proportion of biologically sustainable groups (59.2%), the second group has the highest (76.1%), and the third group is somewhere in between (67.0%). ). If management intervention is not strong, trends in increasing catches (group 3) indicate growing catches and a lack of control. However, when there is an uptrend, there can be significant uncertainty in stock valuations, and the reason one-way travel patterns can be unreliable is due to a lack of comparability due to holding or holding per effort. In contrast, declining catch trends (Group 1) generally indicate a fishery that is sustainable or has implemented stricter regulations, but lacks recovery. The highest level of sustainability (Group 2) may be associated with fully developed fisheries, mature management and effective fishing regulation. However, other factors such as environmental changes and social factors can also influence watershed trends. Box 3 outlines plans to revise current assessment methodologies to better reflect significant changes in the relative advantages of different fisheries.

The results are released every two years to assess and monitor the state of the world’s marine fisheries.

(Sophia) since 1995. The purpose of the review is to provide an overview of global and regional marine fisheries to assist in the development of policy and decision-making for the long-term sustainability of these resources. As marine fisheries develop, assessment methods and related data have undergone significant changes. The current methodology was revised in 2011.
And it hasn’t been updated since. In order to continue to provide a comprehensive and objective global analysis, the Commission decided to revise its methodology to better reflect significant changes in the relative advantage of different fisheries and to base the analysis on a revised and expanded fishery inventory. share. The new approach will update the stock list and provide new reporting formats for new analysis in a progressively transparent manner. The changes are expected to directly connect developing assessment and management bodies and practitioners in member states and increase transparency.
Revised plans to address these issues in future State of the World Marine Fisheries reports are to adopt a regional strategy that uses grading of data linkage to gradually close assessment gaps. The first and most important step is to update the share lists in each regional analysis to better reflect current fishery realities in different parts of the world. This will be done through regional workshops and new forms of consultation in collaboration with local experts, such as Sustainable Development Goal (SDG) indicator 14.4.1 (fish stocks at biologically sustainable levels) using country-specific questionnaires. The standardized evaluation method is based on data quality and additional information for each region:

Two statistical areas (Area 31 and 37) will be submitted to the 35th Session of the Committee on Fisheries (COFI) in 2022 to present this ranking concept within the transparent SOFIA assessment framework. Comparison of existing and new methods in terms of parameters obtained. This pilot program delivers data, workflows, analytics, and reporting in an easily repeatable, standardized format. In addition, new infographics (see preview examples) will be developed to provide a more engaging communication format and present fishery assessments within the wider context of Ecosystems for Fisheries Management (EAFM).
A detailed work plan to achieve SOFIA’s objective of updating indicators on the status of marine resources will be presented to COFI at its 35th session. If accepted, examples of standardized analysis and new visual communication methods will be presented in the 2024 edition.
, and then a detailed description of the method will be published. The work program outlines mechanisms to improve the capacity of national and regional fisheries agencies to assess the status of populations. In addition to reporting on progress towards SDG indicator 14.4.1, the program encourages greater involvement and active involvement of national institutions, with regular submission of analytical results as input into key publications.

Summary of regional data on several indicators relevant to fisheries management and ecosystem complexity
) – In 2019, an average of 66.7% of these groups were biologically sustainable, slightly above the global average of 64.4%. European sardines, Atlantic cod and Atlantic herring are overfished in higher than average numbers.
Tuna resources are extremely important due to large catches, high economic value and extensive international trade. Furthermore, their management faces additional challenges due to their unstable and often unstable distribution. Globally, the seven commercially important tuna species are albacore tuna.
Sustainable Seafood Trends For 2022
). Major commercial tuna caught 5.7 million tonnes of the animals in 2019, a 15% increase from 2017 but still 14% below the historical peak in 2014. On average, 66.7% of major commercial tuna stocks are fished biosustainably. In 2019, the average for all species was slightly higher but the same as in 2017.
Tuna populations are closely monitored and extensively assessed, and the status of the seven tuna species mentioned above is known to be somewhat uncertain. However, other tuna and tuna-like species have been largely unassessed or assessed with a high degree of skepticism. This is a significant challenge because tuna and tuna species account for at least 15% of the global small-scale fisheries (Duke University and WorldFish, forthcoming). In addition, market demand for tuna remains high, and the fishing capacity of the tuna fishing fleet remains high. Effective management, including better reporting and access to information and the implementation of fishing control rules for all tuna stocks, is needed to sustainably maintain stocks, particularly those that establish overfished stocks. In addition, significant additional efforts are required in data collection, reporting and assessment of tuna and tuna species in addition to the major commercial species.
The Northwest Pacific has the highest catch among the major fishing areas, accounting for 24.1% of global landings in 2019. In the 1980s and 1990s, the total catch fluctuated between 17 and 24 million tons, and in 2019 it was 19.4 million tons (Figure 2225). Historically, Japanese sardines (
