Jack mackerel caught by a Chilean purse seiner Fishing down the food web. 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 surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
Overfishing, which NOAA Fisheries is tasked with preventing, is a major threat to biodiversity, global food security, and the fishing sector. [ 20 ] [ 23 ] The MSA also requires that overfished stocks be rebuilt within 10 years, except in cases where the life history characteristics of the stock, environmental conditions or management measures ...
The NOAA conducts general research on ocean resources and is responsible for research on the effects of ocean dumping, pollution, overfishing, and other issues caused by humans that cause changes in the marine ecosystem.
This prompted major amendments in 1996 and 2006. The National Marine Fisheries Service issued a report to Congress in 2010 on the status of U.S. fisheries. It reported that of the 192 stocks monitored for overfishing 38 stocks (20%) still have fish "mortality rates that exceed the overfishing threshold … and 42 stocks (22%) are overfished". [12]
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 ...

Some have questioned if ocean water can be used to battle the blazes (AP) Sea water, in theory, could be used to help a fire. But, its salty components can do more harm than good, which is why ...
