Argentine hake is not expected to disappear, but the stock may be so low that it is no longer economical for commercial fishing. In addition, this adversely affects Argentine employment, because of many jobs in the fishing industries. Conversely, Argentine hake prices rose due to hake scarcity, reducing exports and affecting the economy. In Chile, seafood exports, especially Chilean hake, have decreased dramatically. Hake export has decreased by almost 19 percent. The main cause of this decline is the February 2010 Chile earthquake and tsunami. These disasters destroyed most processing plants, especially manufacturing companies that produce fish meal and frozen fillets. European hake catches are well below historical levels because of hake depletion in the Mediterranean and Black Sea. However, different factors might have caused this decline, including a too-high Total Annual Catch, unsustainable fishing, ecological problems, juvenile catches, or non-registered catches. According to the Worldwide Fund for Nature, the only hake species not currently over-fished is Cape hake, found off Namibia. Namibia is the only country that has increased its hake quota, from in 2009 to in 2010. Furthermore, the Namibian Ministry of Fisheries adheres to very strict rules regarding the catch of hake. For example, the closed seasons for hake lasts approximately two months, in September and October, depending on the level of stock. This rule has been applied to ensure the regrowth of the hake population. Supplemental restrictions forbid trawling for Hake in waters less than deep (to avoid damaging non-target species habitat) and to minimize by-catch. Human introduction to non-native areas Frank Forrester's Fishermens' Guide in 1885 mentions a hake that was transplanted from the coast of Ireland to Cape Cod on the coast of Massachusetts in the United States. It is uncertain which species it was, but the Fishermens′ Guide stated:This is an Irish salt water fish, similar in appearance to the tom cod. In Galway bay, and other sea inlets of Ireland, the hake is exceedingly abundant, and is taken in great numbers. It is also found in England and France. Since the Irish immigration to America, the hake has followed in the wake of their masters, as it is now found in New York bay, in the waters around Boston, and off Cape Cod. Here it is called the stock fish, and the Bostonians call them poor Johns. It is a singular fact that until within a few years this fish was never
