The dataset collected includes assessment output relating to the years from 1905 to 2021 inclusive for annual estimates of the following variables for each stock: the annual recruitment estimate; the stock size (spawning stock biomass); landings (tonnes of fish brought to shore); catches (tonnes of fish caught at sea); fishing pressure (a fishing mortality rate); the target fishing mortality that will achieve maximum sustainable yield in the long term (Fmsy); upper and lower range estimates for Fmsy consistent with multi-annual plans and ICES advice; a threshold for spawning stock biomass (MSYB trigger), below which fishing mortality should be reduced below Fmsy, following the ICES advice rule, to avoid reduced reproductive capacity; a lower limit threshold for spawning stock biomass below which there is a high risk of reduced reproductive capacity (Blim). The stock assessment data for fish and shellfish stocks of UK interest is used to assess indicators of reproductive capacity (based on spawning stock biomass) and fishing pressure (based on fishing mortality). The applicable location for these data differ by stock, but apply to UK stock areas in the Celtic Sea / North Sea / wider North East Atlantic / Arctic region.

Data stating FMSY ranges originate from the ICES advice sheets.

Stock and commodity exchanges can benefit from various sources of revenue, ranging from fees charged through the purchasing and selling of stocks and commodities to the listing of companies on exchanges with IPOs. Yet, this hasn't meant exchanges have been free of challenges, with many companies looking to more attractive overseas markets in countries like the US that embrace stronger growth. The most notable culprits have been ARM and CRH, refusing to put up with the increasingly cheaper valuations offered by UK stock exchanges.Stock and commodity exchange revenue is expected to boom at a compound annual rate of 13% over the five years through 2025-26 to £18 billion, including growth of 5.2% in 2025-26. Boosted by the London Stock Exchange Group's Refinitiv purchase in 2021-22, the growth numbers seem inflated. The industry saw ample consolidations, aided by MiFID II's initiation in 2018. However, M&As have slumped over recent years as a result of high borrowing costs and a foggy economic outlook. Interest rate cuts and growing confidence are set to facilitate a modest recovery over the two years through 2025, driving revenue growth and supporting profit of 25.7% in 2025-26. Exchanges have also capitalised on volatile markets, with nervous investors triggering sharp sell-offs amid a tense geopolitical backdrop with Trump’s tariff policies. Consolidation amongst the largest players has been frequent, ratcheting up market share concentration. This will also prompt smaller exchanges to target niche markets and potentially band together in networks or alliances to pool liquidity and strengthen bargaining power. Revenue is forecast to climb at a compound annual rate of 4.7% over the five years through 2030-31 to £22.7 billion. Over the short term, sticky inflation and how aggressively the Bank of England cuts rates will incite volatility and fuel trading on exchanges, driving revenue growth. Geopolitical tensions also show no signs of cooling, with the potential for matters to even escalate, keeping markets edgy and increasing the likelihood of large market swings. The use of blockchain will become more prevalent, with major player, the London Stock Exchange Group, already introducing a blockchain-based infrastructure platform for private markets. These exchanges allow for 24/7 trading, lower settlement times, and often lower fees, which can attract retail and institutional participants, driving fee income.
