Which of the following measures was adopted by ICCAT at the Istanbul meeting?

Delegates at an international conservation meeting agreed Saturday on a measure mandating that silky sharks accidentally caught in fishing gear be released back into the sea alive. But this 48-member International Commission for the Conservation of Atlantic Tunas (ICCAT) failed to reach consensus on other threatened shark species at the end of their meeting in Istanbul.
    ICCAT, which manages tuna in the Atlantic and Mediterranean — as well as species, like sharks, that have traditionally been accidental catches for tuna fishermen — made an exception for coastal developing countries, where the silky sharks can continue to be caught for local consumption of their meat and not for the trade of their fins.
    The sharks, named after the silk-like smooth texture of their skins, are among shark species most vulnerable to decline, threatened by the international trade in shark fins due to an increasing demand mainly in Asia for shark fin soup.
    Other measures adopted by ICCAT in Istanbul include a requirement for members to submit data on the species they catch or risk losing their right to catch those species in the following year. The group has said that failure to report on catches; was preventing conservationists from adequately assessing the impact of fisheries on threatened species.
