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 fishing industry sector is a small contributor to greenhouse gas emissions overall but nevertheless there are options for reducing fuel use and greenhouse gas emissions. [7]: v For example, about 0.5 percent of total global CO 2 emissions in 2012 were caused by fishing vessels (including inland vessels): 172.3 million tonnes of CO 2. [7]
Besides severe health concerns, water pollution also leads to problems in the fishing and tourism industries. [34] The national government recognized the problem and since 2004 has sought to introduce sustainable water resources development management (see below). [35] Only 10% of the total population is connected to a sewer network. [36]

Fisheries objectives need to be expressed in concrete management rules. In most countries fisheries management rules should be based on the internationally agreed, though non-binding, Code of Conduct for Responsible Fisheries, [8] agreed at a meeting of the U.N.'s Food and Agriculture Organization FAO session in 1995.
With the absence of foreign fishing, many Canadian and American fishing trawlers took their place, and the number of cod kept diminishing past the point of recovery. [12] Many local fishers noticed the drastic decrease of cod and tried to inform local government officials. [citation needed] In a 1978 white paper, the Newfoundland government ...
For example, the fishing effort exerted by a fishing fleet in a trawl fishery might be measured by summing the products of the engine power for each boat and time it spent at sea (KW × days). For a gill-net fishery the effort might be measured by summing the products of the length of each set net and the time it was set in the water (Km × ...
The UK fishing industry contributed £446 million in 2019 in terms of GVA); this represents 0.02% of the UK's total GVA. [4] Updated statistics from Marine Management Organisation on the UK fishing sector show that UK vessels landed 724 thousand tonnes of sea fish in 2017, with a value of £980 million. [5]
