Conserving marine biodiversity, avoiding species extinction and maintaining food security from wild capture fisheries can all be achieved simultaneously if a global, non-regionalized approach to marine spatial management is undertaken by the signatories of IUCN Resolution 50, which calls for the protection of 30 per cent of the ocean by 2030.
Silver-cheeked
toadfish Lagocephalus
sceleratus, a poisonous invasive
species thriving in the Eastern Mediterranean Sea since the mid-2000s after it
crossed the Suez Canal from the Red Sea, is now reaching monstrous sizes around
the Greek islands near the Turkish coast.

Fisheries managers and researchers may now predict how early fish will spawn in response to warming waters due to climate change, both in the oceans and in freshwaters.
A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active – and spawn for the first time – in response to growth-induced respiratory stress.
A new report by leading fisheries experts found that over 99 percent of bottom trawling worldwide occurs inside the Exclusive Economic Zones of coastal nations—with much of the effort focused within just 12 miles of shore— posing risks to critical habitats and traditional, small-scale, artisanal fishing operations. As the only globally significant fishing practice that requires sustained contact with the seabed, bottom trawling has a uniquely high impact, one that can drive habitat destruction, coastal conflict and major fuel-related carbon emissions.
