New report on the definition of “maximum sustainable yield” in fisheries

The Blue Marine Foundation has produced a report looking at the legality of fishing beyond maximum sustainable yield (MSY).

The report, led by the University of the West of England, has two key findings: that it is illegal for coastal states to permit fishing beyond MSY; and that it is highly likely that this law is enforceable through the court system. The report also investigates the legal meaning of the term MSY and the historical context of the term.

The Executive Summary of the report reads: “The EU now has a commitment that fishing will progressively be managed at levels that correspond to MSY, and setting of quotas will respect scientific advice. Where possible, this is to be attained by 2015, and all fish stocks will be managed at MSY by 2020 at the latest.

What the term ‘maximum sustainable yield’ means will dominate the next seven years of fisheries discussions. MSY has two different interpretations.

Scientists use the term to mean the ability of a fish stock to support a sustainable fishing industry. Lawyers use it when assessing the obligations of a country in respect of its sovereign fishing rights. This report focuses on the legal interpretation of MSY.

The report’s findings are particularly important as the EU has consistently over-allocated quota and ignored scientific advice, with the result that 75% of EU fish stocks are overfished. The starting point of a thorough investigation of MSY is the nature of fishing rights themselves. Fisheries were traditionally open access and seen as being inexhaustible. The origins of this approach date at least as far back as the era of the Roman Empire, but even then interpretation by the Roman courts created some perverse outcomes. The principle of open access became established for the English fishery in the 12th century. Before then, it is likely that all viable tidal fisheries were granted by the Crown into private hands following the Norman conquest. Indeed, some of these private tidal fisheries still persist today.

In the seventeenth century, the mare liberumMare liberum a navigable body of water to which all nations have equal access (freedom of the seas) debate confirmed open access on the high seas, but the position for territorial waters (within the 3 mile limit) was more complex. Under the common law, fishers operated under the public right to fish which permitted open access and has come to be interpreted as being based on the principle of inexhaustibly of the stock. Where this myth of inexhaustibly has come from is difficult to tell. It is often attributed to the Victorian scientist Thomas Huxley because of his pronouncement on the fecundity of some fish species, but Huxley himself highlights fisheries which were vulnerable to over-fishing and recognises that, on the high seas, no regulatory mechanisms were available, so this aspect of his findings was theoretical.

Moreover, the negative impacts of some fisheries were known to the legislators at least since the Middle Ages and it is tempting to posit that public authorities, in whatever form they manifested themselves, have always been aware that some fishing methods can cause significant harm. As it stands, the basic principle the courts still adhere to is that the right to fish is untrammelled, but whether this principle would withstand direct judicial scrutiny is questionable.

The United Nations Convention on the Laws of the Sea (UNCLOSUNCLOS The United Nations Convention on the Law of the Sea, also called the Law of the Sea Convention or the Law of the Sea treaty.) changed everything. Coastal states now enjoy sovereign rights over a far larger area of sea than they did previously. UK territorial waters now extend to 12 nautical miles and its exclusive economic zone (EEZ) extends up to 200 nautical miles. UNCLOS recognises sovereign rights for fisheries but also imposes duties on coastal states to restore stocks to levels which can produce MSY within their EEZs.

Sovereign fishing rights are not untrammelled; they are qualified by a duty to restore stocks and to preserve the marine environment. Similar obligations are contained in the Convention on Biodiversitybiodiversity Biological diversity in an environment as indicated by numbers of different species of plants and animals. (with a target for 2020) and by virtue of the World Summit for Sustainable Development (with a target of 2015 for depleted stocks). Increasingly, international obligations of this nature are being enforced through the domestic courts.

Many countries (including the UK itself for its Crown Dependencies and overseas territories) vest their fishing rights in an identifiable legal entity which then not just regulates the fishery, but also acts as an owner in the way it disposes of the fishery to commercial operators. Unfortunately, for the waters immediately adjacent to the UK, it is not clear in what Crown entity the UK’s fishing rights actually vest.

The UK fishery is clearly some form of public asset and it is likely that there is a Crown trust in existence. The terms of this trust would place similar duties to maintain and restore fish stocks as those contained within UNCLOS. Despite a first instance decision to the contrary, it is possible that the terms of that trust are enforceable by third parties.

There is a well-established principle in English law of nemo dat quod non habet (you cannot dispose of something you don’t own). The fact that the UK’s sovereign rights are qualified to MSY mean that the UK cannot grant to its fishers (or fishers of other Member States operating in UK waters) untrammelled rights which it does not possess itself. The same principle applies to the EU Common Fisheries Policy; the UK cannot confer on the EU greater fishing rights than those acknowledged by UNCLOS.

The scientific origins of the term MSY were in the work of Beverton and Holt and related to a theoretical maximum, where a capture fishery will sustain itself. The legal meaning of the term gives discretion to fisheries managers to establish a management system which uses the best available science

to determine what actions needs to be taken. The legal interpretation of MSY is therefore much broader than the scientific one and has the following features:

  • it is constantly evolving relating to the best available science of the time;
  • it defines the limits of a coastal state’s sovereign rights;
  • it may relate to the setting of fishing quota (where calculations of scientific MSY are particularly predominant), but many obligations for the attainment of MSY may also be satisfied by the imposition of technical or area-based management techniques such as marine protected areas;
  • it provides the framework in which fisheries should be managed; and
  • it can be used to show where stocks or areas of sea are not being properly managed, and thus direct where management resources should be targeted.

The introduction of the ecosystem approachecosystem approach An ecosystem-based approach to management represents a new and more strategic way of thinking. It puts the emphasis on a management regime that maintains the health of ecosystems alongside appropriate human use of the marine environment, for the benefit of current and future generations. This requires setting clear environmental objectives both at the general and specific level, basing management of the marine environment on the principles of sustainable development, conservation of biodiversity, robust science, the precautionary principle and stakeholder involvement. Ref, DEFRA, Safeguarding Our Seas, section 1.17 (2002) to fisheries management means that legal MSY can now take into consideration a much wider range of services provided by the fishery in the calculation and management of that fishery. UNCLOS itself permits taking into consideration relevant environmental and economic factors, including the economic needs of coastal fishing communities, but the ecosystem approach takes that a stage further by assessing all the

services provided by the fishery. This shifts the focus away from simply treating the fishery as a commercial resource, to ensure that management benefits a much broader constituency.

In 2008, the environmental non-governmental organisation (NGO), WWF tried to take the European Commission to the European Court of Justice for failing to allocate cod quota according to scientific advice. However, WWF was unable to access the European court system because the ECJ refused access to NGOs; ECJ rules at the time did not grant an NGO the right to be heard in court. Those rules are under scrutiny once again because they seem incompatible with the Aarhus Convention, so this position may change shortly.

There are also other legal forums for testing the point. The UK courts do not have the same access restrictions as the ECJ, so a case launched in the UK courts concerning UK fishing rights or the voting patterns of the UK Minister in the EU could come to trial. The former President of the International Tribunal for the Laws of the Sea (ITLOS), Rüdiger Wolfrum, recommended ITLOS as having suitable jurisdiction to ensure compliance with MSY requirements

The legal regime has dramatically moved away from the impossibility of mare liberum and open access fisheries to the possibility of effective regulation. Clearer sovereignty over the sea and better technology informing enforceable law means the legal context of fisheries have changed fundamentally for the better. There is an understanding that fisheries are held on trust for future generations. Fishing to MSY and trusteeship amount to the same thing; the legal interpretation of coastal states’ rights and responsibilities under MSY and the obligations of a Crown trust are the same.

The ecosystem approach provides the matrix to understand who the beneficiaries of that trust are and where management effort needs to be directed. All these pieces are now in place and the hard law is there at the edges to ensure that reform remains on track. In short there are two key points to be drawn from this report:

  • It is illegal for coastal states to permit fishing beyond MSY; and
  • It is highly likely that this law is enforceable through the court system.
