For stocks where data are too poor to properly estimate their size, the Commission applied a so-called precautionary principle, reducing the TACs by between 15% and 25% until more reliable data are available.
Nende kalavarude puhul aga, mille suuruse kindlakstegemiseks oli liiga vähe andmeid, kasutas komisjon nn ettevaatusprintsiipi, vähendades lubatud kogupüüki 15–25%, kuni saadakse usaldusväärsemaid andmeid.
