In addition, industry observers believe illegal, unreported and unregulated fishing occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. [10] In a phenomenon called fishing down the foodweb, the mean trophic level of world fisheries has declined because of overfishing high trophic level fish. [11]

Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
The number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said. The National Oceanic and Atmospheric Administration ...

Fishermen and scientists were alarmed when billions of crabs vanished from the Bering Sea near Alaska in 2022. It wasn’t overfishing, scientists explained — it was likely the shockingly warm ...
Cruise ships discharge waste into the sea Another impact of tourism is marine pollution from cruise ships discharging waste into the sea. One single trip of a large cruise ship on average produces 210,000 gallons of sewage, 1,000,000 gallons of grey water , 125 gallons of toxic chemicals and hazardous waste, 8 tons of garbage and 25,000 gallons ...
