Encyclopedia > Fisheries management

Fisheries management is today often referred to as a governmental system of management rules based on defined objectives and a mix of management means to implement the rules, which is put in place by a system of monitoring, control, and surveillance (MCS). Modern fisheries management is most often based on biological arguments where the idea is to protect the biological resource in order to make a sustainable exploitation possible. Biology is the science of life (from the Greek words bios = life and logos = reasoned account). ...

History

The control of fisheries and fish production has been exercised in many places around the world for hundreds of years.


For example, the Maori people, residents of New Zealand for about the last 900 years, had strict rules in their traditional fishing activities about not taking more than could be eaten and about throwing back the first fish caught (as an offering to Tangaroa, god of the sea). Te Puni, Māori Chief Māori is the name of the indigenous people of New Zealand, and their language. ...


Another longstanding example is the North Norwegian fishery off the Lofoten islands, where a law has existed for more than 200 years to control fishing activity, in this case primarily motivated by problems occurring during periods of high density of fishers and fishing gear. To avoid gear collisions, gillnetters and longliners are separated and not allowed to fish in the same grounds south of Lofoten. Nord-Norge (Norwegian for Northern Norway) is the name of the geographical region of northern Norway, consisting of the three counties Nordland, Troms and Finnmark. ... Small vessels fishing cod (skrei) outside Flakstad island (March, 2005). ...


Governmental resource protection-based fisheries management is a relatively new idea, first developed for the North European fisheries after the first Overfishing Conference held in London in 1936. In 1957 the British fisheries researchers Ray Beverton and Sidney Holt published a seminal work on North Sea commercial species fisheries dynamics. The work was later (in the 1960s) used as a theoretical platform for the new management schemes set up in North European countries. Overfishing is a situation where one or more fish stocks are reduced below predefined levels of acceptance by fishing activities. ... 1936 was a leap year starting on Wednesday (link will take you to calendar). ... 1957 was a common year starting on Tuesday (link will take you to calendar). ... The North Sea is a sea of the Atlantic Ocean, located between the coasts of Norway and Denmark in the east, the coast of the British Isles in the west, and the German, Dutch, Belgian and French coasts in the south. ... In biology, a species is a kind of organism. ... Events and trends The 1960s was a turbulent decade of change around the world. ...


After some years away from the field of fisheries management, Ray Beverton reassessed his earlier work and in a paper given at the first World Fisheries Congress in Athens in 1992, he criticised some of the concepts that he had earlier laid out in "The Dynamics of Exploited Fish Populations" and expressed concern at the the way his and Sydney Holt's work has been misinterpreted and misused by so many fishery biologists and managers during the previous 30 years. Nevertheless, the institutional foundation for modern fishery management had been laid.


Objectives

The political goal of resource use is often a weak part of the system of fisheries management, as conflicting objectives are often found.


Political objectives often found when exploiting a fish resource:

  • Maximise sustainable biomass yield (see optimum sustainable yield)
  • Maximise sustainable economic yield (see maximum sustainable yield)
  • Secure and increase employment in certain regions
  • Secure protein production and food supply
  • Increase income from export

In economics, optimum sustainable yield is the level of effort that maximizes the difference between total revenue and total cost. ... In fisheries science, maximum sustainable yield or MSY is the largest long-term average yield/catch that can be taken from a stock of fish without depressing the species ability to reproduce. ...

Management rules

International agreements are required in order to regulate fisheries taking place in areas outside national control. The desire for agreement on this and other maritime issues led to the three conferences on the Law of the Sea, and ultimately to the treaty known as the United Nations Convention on the Law of the Sea (UNCLOS). Concepts such as exclusive economic zones (extending up to 200 nautical miles from coastlines) allocate certain sovereign rights and responsibilities for resource management to individual countries. In the case of highly migratory species and stocks straddling boundaries, this sovereign responsibility must be exercised in collaboration with neighbouring Coastal states and fishing entities, usually through the medium of an intergovernmental regional organisation set up for the purpose of coordinating the management of that stock. The term United Nations Convention on Law of the Sea (UNCLOS, also called simply the Law of the Sea or LOS) refers to several United Nations events and one international treaty. ... In international maritime law, an exclusive economic zone (EEZ) is a seazone extending from a states coast over which the state has special rights over the exploration and use of marine resources. ... United States that have a coastline. ...


UNCLOS does not prescribe precisely how fisheries that occur solely in international waters should be managed, and there are several new fisheries (such as high seas bottom trawl fisheries)that are not yet subject to international agreement across their entire range. Both of these issues "came to a head" within the United Nations in 2004 and the UN General Assembly issued a resolution on Fisheries in November 2004 which set the scene for the further development of international fisheries management law. United Nations General Assembly The United Nations General Assembly is one of the six principal organs of the United Nations. ...


Fisheries objectives need to be expressed in concrete management rules. In most countries the management rules today should be based on the internationally agreed, albeit non-binding, standard Code of Conduct for Responsible Fisheries, agreed at an FAO session in 1995. The precautionary approach prescribed here is also implemented in concrete management rules as minimum spawning biomass, maximum fishing mortality rates, etc. Headquartered in Rome, Italy, the Food and Agriculture Organization (FAO) of the United Nations programs seek to raise levels of nutrition and standards of living; to improve the production, processing, marketing, and distribution of food and agricultural products; to promote rural development; and, by these means, to eliminate hunger. ... 1995 was a common year starting on Sunday of the Gregorian calendar. ... The precautionary principle, a phrase coined circa 1988, is the ethical principle that if the consequences of an action, especially the use of technology, are unknown but are judged by some scientists to have a high risk of being negative from an ethical point of view, then it is better... This article is about biological spawning. ...


Management mechanisms

When it comes to controlling the activities of individual fishers or fishing operations (vessels or companies), available management means can be sorted into four categories:

Taxation on input Taxation on output
Limited entry control Catch quota and technical regulation

The top row represents indirect methods while the bottom row represents direct methods of regulation. The left column shows input controls and the right column output controls. A quota is a prescribed number or share of something. ...


Many countries have set up Ministries and Government Departments, named "Ministry of Fisheries" or similar, controlling aspects of fisheries within their exclusive economic zones. Many states have set up government departments, usually called ministries, which regulate fisheries management within the states exclusive economic zone. ... In international maritime law, an exclusive economic zone (EEZ) is a seazone extending from a states coast over which the state has special rights over the exploration and use of marine resources. ...
