Around the world, many fisheries are governed by rules that make the problem worse, or have no rules at all. Following the depletion of large pelagic predator and demersal fish stocks during the 1950–1960s, the main fishery was targetted on small and medium pelagics that declined abruptly to ∼200 kton (kton = 103 t) at 1989–1991 after a highly productive (∼750 kton) but overfished state in the 1980s. This depletes the adult fish population and does not leave enough fish to breed and restock their numbers so … ... state and international agreements as well. Overfishing often goes hand in hand with wasteful types of commercial fishing that haul in massive amounts of unwanted fish or other animals, which are then discarded.

Thereafter, total landings in all the Black Sea countries except Turkey remained at most 10% level of the previous phase. The absence of fish within the western, eastern and northern regions and the presence of only a fluctuating heavily exploited anchovy fishery in the southern region during the last 20 years demand an immediate common ecosystem-based fishery management policy and actions by all the coastal states. Long-term (1950–2006) changes of fish landings in combination with some ecosystem indicators are used to evaluate the status and sustainability of the Black Sea fishery.

Our ratings for wild-caught species take into account whether the seafood came from healthy, abundant populations and whether they are being fished at sustainable levels. Many fish are caught to the point that there aren’t enough remaining within an ecosystem to survive, or are caught before they have fully matured. Without sustainable management, our fisheries face collapse — and we face a food crisis. Following the depletion of large pelagic predator and demersal fish stocks during the 1950–1960s, the main fishery was targetted on small and medium pelagics that declined abruptly to ∼200 kton (kton = 10 3 t) at 1989–1991 after a highly productive (∼750 kton) but overfished state in the 1980s.
