(a) države naj zagotovijo, da se podatki o ribolovni aktivnosti plovil pod njihovo zastavo zbirajo glede na značilnosti posameznega načina ribolova (npr. vsak posamezen izvlek mreže, vsak met parangala in zaporne plavarice, vsak ulov z ribiško palico in vsak dan ribolova s panulo) in da so dovolj podrobni za učinkovito oceno staležev;
(a) States should ensure that data are collected from vessels flying their flag on fishing activities according to the operational characteristics of each fishing method (e.g., each individual tow for trawl, each set for long-line and purse-seine, each school fished for pole-and-line and each day fished for troll) and in sufficient detail to facilitate effective stock assessment;
