Regulation & Ethics of Marine Harvesting
Marine harvesting is the collection of resources from the ocean, including fish, seals, whales, and dolphins
It is governed by international regulations, particularly within a country’s exclusive economic zone (EEZ)
It involves complex ethical considerations, especially regarding endangered species and traditional hunting practices
United Nations Convention on the Law of the Sea (UNCLOS)
UNCLOS is a convention created in 1982
It is the law and governance of all oceans and resources
The convention separates the ocean into 5 marine areas:
Internal waters
Waters on the landward side of the baseline are considered internal waters
The coastal state has full sovereignty over these waters
Territorial sea
Extends 12 nautical miles from the baseline
The coastal state has sovereignty over these waters, similar to its land territory
Foreign ships have the right of innocent passage, but the coastal state can regulate activities in this zone
Contiguous zone
Extends from 12 to 24 nautical miles from the baseline
The coastal state can enforce laws concerning customs, immigration, and pollution within this zone
But it does not have full sovereignty like in the territorial sea
Exclusive economic zone
Extends from the baseline out to 200 nautical miles
The coastal state has exclusive rights to explore and use marine resources, including fishing and oil extraction
Other nations may pass through or lay submarine cables, but they must respect the state's regulations on resource use
High seas
The areas of the ocean that lie beyond the EEZ
These waters are beyond any single country's national jurisdiction
No state has sovereignty over the high seas
They are open to all nations for activities like fishing, shipping, and scientific research
Exclusive economic zone (EEZ)
Governmental control within the EEZ includes making decisions on:
The number of fish that can be caught
Who can fish?
Which species can be targeted?
Some countries sell access to their EEZ to foreign nations or fishing companies rather than managing resources for the benefit of local people
This raises equity and justice issues
For example, poorer nations might sell fishing rights to wealthy foreign companies
This can lead to overfishing, depriving local communities of fish resources
Local fishers may suffer when larger foreign fleets overfish their waters, reducing the availability of fish for the community and harming ecosystems
High seas regulation
Beyond the EEZ lie the high seas, which cover nearly 60% of the world’s oceans
In these areas, there is limited regulation and governance
International bodies like the United Nations have developed treaties to:
Protect these waters
Regulate activities such as fishing, shipping, and seabed mining
In 2023, the UN signed an International Treaty on the High Seas to:
Create marine protected areas (MPAs)
Improve the regulation of fishing and other activities in the high seas
Ethical issues in marine harvesting
Harvesting of seals, whales, and dolphins
The hunting of marine mammals, such as seals, whales, and dolphins, raises ethical issues related to animal welfare, conservation, and cultural practices
Some species of whales and dolphins are endangered, and their hunting is highly controversial
Perspectives on marine mammal hunting
Animal rights perspective:
The hunting of seals, whales, and dolphins is often seen as unethical due to the intelligence and social nature of these animals
Activists argue that killing marine mammals is inhumane and unnecessary, particularly when alternatives to animal products are available
For example, the hunting of pilot whales in the Faroe Islands (known as the grindadráp) faces international criticism due to concerns over animal cruelty and the sustainability of whale populations
Indigenous rights perspective:
Indigenous groups have traditionally hunted marine mammals for food and cultural reasons
For these communities, such as the Inuit, hunting provides food, materials, and a connection to their ancestral traditions
Many indigenous groups argue that their hunting practices are sustainable and should be protected as part of their cultural rights
For example, the Inuit continue to hunt narwhals and seals as part of their traditional way of life
International Whaling Commission (IWC)
The IWC regulates whaling, setting limits on how many whales can be hunted each year and which species are protected
While the IWC has largely banned commercial whaling, some countries, like Japan, have continued to hunt whales for 'scientific purposes'
This has been criticised as a loophole for commercial whaling
