Description
Hakes are medium-to-large fish averaging from in weight, with specimens as large as . The fish can grow up to in length with a of as long as 14 years.

Hake may be found in the and in waters from deep. The fish stay in deep water during the day and come to shallower depths during the night. An undiscerning , hake feed on prey found near or on the . Male and female hake are very similar in appearance.

After , the hake eggs float on the surface of the sea where the larvae develop. After a certain period of time, the baby hake then migrate to the bottom of the sea, preferring depths of less than .

  • ( Merluccius bilinearis), found in the Northwest Atlantic Ocean
  • Southern hake ( Merluccius australis), found off and off New Zealand


Commercial use
Not all hake species are viewed as commercially important, but the deep-water and shallow-water hakes are known to grow rapidly and make up the majority of harvested species. Indicators of quality in hake products for human consumption include white free of signs of browning, dryness, or grayness, and with a fresh, seawater smell. Hake is sold as frozen, or steaks, fresh, , or .


Fisheries
The main catching method of deep-water hake is primarily , and shallow-water hake is mostly caught by inshore trawl and . Hake are mostly found in the Southwest Atlantic ( and ), Southeast Pacific ( and ), Southeast Atlantic ( and ), Southwest Pacific (), and and (, , , and ).


Over-exploitation
Due to , Argentine hake catches have declined drastically. About 80% of adult hake has apparently disappeared from Argentine waters. 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 . These disasters destroyed most processing plants, especially manufacturing companies that produce and frozen fillets.

European hake catches are well below historical levels because of hake depletion in the and . Various factors might have caused this decline, including a too-high total allowable catch, unsustainable fishing, problems, juvenile catches, or non-registered catches.

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 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 for Hake in waters less than deep (to avoid damaging non-target species ) and to minimize .


Human introduction to non-native areas
's Fishermens' Guide in 1885 mentions a hake that was transplanted from the coast of to on the coast of in the . It is uncertain which species it was, but the Fishermens' Guide stated:
This is an Irish fish, similar in appearance to the tom cod. In , and other sea of Ireland, the hake is exceedingly abundant, and is taken in great numbers. It is also found in and . Since the 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 , 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 seen in America. It does not grow as large here as in Europe, though here they are from ten to eighteen inches 250 in length.... The general color of this fish is a reddish brown, with some golden tints—the sides being of a pink silvery luster.
