Lepeophtheirus salmonis, or the common salmon louse, now infests nearly half of Scotland’s salmon farms. Last year lice killed thousands of tonnes of farmed fish, caused skin lesions and secondary infections in millions more, and cost the Scottish industry alone around £300m in trying to control them. Scotland has some of the worst lice infestations in the world, and last year saw production fall for the first time in years. But in the past few weeks it has become clear that the lice problem is growing worldwide and is far more resistant than the industry thought. Norway produced 60,000 tonnes less than expected last yearbecause of lice, and Canada and a dozen other countries were all hit badly. Together, it is estimated that companies across the world must spend more than £1bn a year on trying to eradicate lice, and the viruses and diseases they bring. As a result of the lice infestations, the global price of salmon has soared, and world production fallen. Earlier this year freedom of information [FoI] requests of the Scottish government showed that 45 lochs had been badly polluted by the antibiotics and pesticides used to control lice – and that more and more toxic chemicals were being used.
“Sea lice are a natural phenomenon,” says Scott Landsburgh, chief executive of the Scottish salmon producers association. “All livestock on farms, terrestrial or marine, are encountering some kind of parasite or tick, and they’re dealt with. And that’s part of livestock farming. We are no different to terrestrial farms. Problems come and go, depending on biology and the environment. The louse is a hardy parasite. It’s a challenge for Chile and Norway, too. We are spending a lot on all sorts of things.”The salmon-farming industry, which has grown at breakneck speed since the 1970s, knows it has a huge problem, but insists it sees the lice as unwelcome guests that will soon be evicted rather than permanent residents. Rather than dwell on the lice, industry leaders point to the fact that in just 40 years, aquaculture has gone from providing 5% of the world’s fish to nearly 50%, and in Scotland, from a few hundred tonnes of salmon a year to more than 177,000 tonnes in 2015. They argue that new methods to control infestations are being developed and the chemicals being used are safe and degrade quickly, adding that they expect to have found a solution within a few years.
The global companies that dominate ownership of the farms, buoyed by high prices and growing worldwide demand, are confident that they will find solutions. Marine Harvest, the giant Norwegian multinational that grows 40,000 tonnes of salmon in its many Scottish farms, said this week that it needs to develop more effective ways to combat lice. The use of the toxic drug emamectin rising fast, but also that the industry had persuaded the Scottish environmental protection agency to withdraw a ban planned for next year. Other papers showed that the levels of chemicals used to kill sea lice have breached environmental safety limits more than 100 times in the last 10 years. The chemicals have been discharged into the waters by 70 fish farms run by seven companies.
FoI documents show that the Scottish industry wants to “innovate” by building the world’s biggest salmon farm, which would triple the size of the largest now in operation. It could farm 2m fish at a time, and create as much waste as a city the size of Glasgow. The anwwer to the inevitable lice problems, say environmentalists, is to move the farms further offshore into deeper, colder waters, where lice are less able to survive, or to even put them on land, where they could be better controlled. But this would add greatly to industry costs and require investments of billions of pounds. In the meantime, the companies are using mechanical ways to trim the lice from the fish. These range from pumping the fish through water hot enough to make the lice let go of their hosts, to churning them as if in a washing machine. Both are condemned by animal welfare group Compassion in World Farming, and are known to be expensive and not always effective. Last year the heating of the water on a Skye fish farm led to the accidental slaughter of 95,000 fish. Another 20,000 died in another incident.
Over 170 delegates attended the 10th International Forum on Illegal, Unreported and Unregulated Fishing which took place on the 16 and 17 March. Diverse perspectives and ideas were offered in all sessions; themes included the ‘next steps’ for the FAO Port State Measures Agreement, IUU fishing on the high seas, small-scale fisheries and developing nations, the role of industry and the private sector, technology and big data and the nexus of IUU fishing, geopolitics and resource security.
PowerPoint presentations can now be accessed through the online agenda and a summary of the discussions will be released in the coming weeks.
We would like to reiterate our sincere thanks to the expert speakers and chairs in each of the sessions, and in particular to the forum’s keynote speaker, H.E. Said Jama Mohamed, Deputy Minister of Fisheries and Marine Resources, Somalia.

Session 2 | ‘Tragedy of the Commons’: Regulating the High Seas How can the gap between international conventions and practical implementation and enforcement on the high seas be bridged? A discussion on the implications of IUU fishing on the Arctic sea will follow the formal presentations, raising important questions around fisheries management and high seas governance predominantly through the lens of the Central Arctic Ocean, which may be navigable as early as the first half of this century.
– Are current international conventions and instruments effectively mitigating IUU fishing on the high seas?
– How can we address the intersection of IUU fishing and sustainability in international laws on the high seas? ·
– Does the establishment of the Ross Sea MPA, the largest MPA to date, present a model for future progress in governing the high seas?

Written by 80 European scientific experts from more than 25 institutions, this first Copernicus Marine Service Ocean State Report is a step forward into the development of regular annual reporting on the state and health of the Global Ocean and European Seas based on CMEMS capabilities.
The Copernicus Marine Service Ocean State Report provides an annual report of the state of the global ocean and European regional seas for ocean community, policy and decision-makers with the additional aim of increasing general public awareness about the status of, and changes in, the marine environment.
The Ocean State Report draws on expert analysis and provides a 4-D view(through reanalysis systems), from above (through remote sensing data) and directly from the interior (through in situ measurements) of the blue (hydrography, currents), white (sea ice) and green (e.g. Chlorophyll) global ocean and the European Seas.

Indonesia has pledged up to $1bn a year to dramatically reduce the amount of plastic and other waste products polluting its waters. The announcement was made by Luhut Binsar Pandjaitan, Indonesia’s coordinating minister for maritime affairs at last week’s 2017 World Oceans Summit in Nusa Dua, Bali.
Pandjaitan told delegates at the conference that Indonesia would achieve a 70% reduction in marine waste within eight years. He proposed developing new industries that use biodegradable materials such as cassava and seaweed to produce plastic alternatives. Other measures could include a nationwide tax on plastic bags as well as a sustained public education campaign.
The World Bank estimates that each of Indonesia’s 250 million inhabitants is responsible for between 0.8 and 1kg of plastic waste per annum. Only China dumps more waste in the ocean, according to a 2015 report in the journal Science.
The world’s second biggest plastic polluter also boasts the world’s highest levels of marine biodiversity. Indonesia lies at the heart of the Coral Triangle; its incredibly rich coral reef ecosystems support crucial fisheries, provide food security for millions and are a growing draw for tourists.
Plastic pollution is just one of the threats to these ecosystems services, but it’s a serious one. A recent study suggests that by 2050, there could be more plastic than biomass in the world’s oceans. Plastics have entered the marine food chain and are already reaching our dinner plates.
Indonesia’s commitment is part of the UN’s new Clean Seas campaign, which aims to tackle consumer plastics through a range of actions – from cutting down on single use plastics such as shopping bags and coffee cups to pressuring firms to cut down on plastic packaging. Nine countries have already joined Indonesia in signing up to the campaign, including Uruguay, which will impose a tax on single use plastic bags and Costa Rica, which is promising better waste management and education.
Indonesia’s target of a 70% reduction by 2025 is ambitious. Across the country’s 17,000 islands there is poor public understanding of the problems created by plastic waste.
During rainy season, thousands of tonnes of rubbish discarded in rivers and waterways washes up on Indonesia’s shores. Heavy machinery is often brought in to clear the tourist beaches of Bali and local communities and non-profits are constantly organising large scale beach clean ups.Companies produce small scale products such as single use shampoo packets and confectionery that are popular in communities where cash flow pressures and habit prevent more sustainable consumption. Add poor waste management infrastructure and the scale of the challenge comes into sharp focus.
Last year, a tax on single use plastic bags was trialed in 23 cities across Indonesia. While the government reported a big reduction in plastic bag use, there was significant resistance both from consumers and industry, according to Siti Nurbaya, Indonesia’s minister for the environment. This is delaying a bill to impose a nationwide tax of not less than Rp.200 (1p) per plastic bag.
Environmentalists will be hoping that the promised funding effectively channels resources and expertise into public awareness and education programmes, improvements in waste management, pressure on industry and initiatives that encourage alternatives to plastic packaging. The UN Clean Seas campaign reminds us all, however, that plastic pollution is a problems we can all address with some very simple changes in behaviour.

New research has convincingly quantified how much the Earth has warmed over the past 56 years. Human activities utilize fossil fuels for many beneficial purposes but have an undesirable side effect of adding carbon dioxide to the atmosphere at ever-increasing rates. That increase – of over 40%, with most since 1980 – traps heat in the Earth’s system, warming the entire planet.
But how fast is the Earth warming and how much will it warm in the future? Those are the critical questions we need to answer if we are going to make smart decisions on how to handle this issue.
At any time the direct effect of this blanket is small, but the accumulated effects are huge and have consequences for our weather and climate. Over 90% of the extra heat ends up in the ocean and hence perhaps the most important measurements of global warming are made in the oceans.
