Big Brother Is Watching: Satellites Used to Survey Fishing in High Seas

December 21, 2020 — New research revealed Friday has shed new light on the companies around the world that carry out fishing operations in Earth’s most unregulated waters, as satellite data revealed their activities amid concerns of violations of labor and environmental laws and overfishing.

To help address these concerns, researchers published a study in the journal One Earth that brings to light a number of international companies that operate on the high seas, an effort that researchers say provides a new resource with which to gauge what exactly is happening in such unmonitored environments.

Jennifer Jacquet, associate professor at NYU’s Department of Environmental Studies and lead author of the study, said that the research is the first of its kind to promote this much-needed transparency in these critical areas.

“There is a lot of concern about companies that operate on the high seas, simply because there they are beyond the reach of any nation’s laws and regulations,” Jacquet said in a statement. “By connecting those boats with specific companies, this study takes a first step in enhancing transparency — we now know a lot more about who is profiting from fish catches in the global commons.”

Despite the strict control that numerous nations exercise over much of the world’s seas and oceans, there are nonetheless great stretches of waters around the globe that remain ownerless. These waters, commonly referred to as high seas or international waters, are in fact so vast that they make up nearly two-thirds of Earth’s oceans and have become notorious throughout the years for their lack of oversight and regulations.

Octopus Farms Could Become a Reality. Scientists Warn This Isn’t a Good Idea

October 8, 2020 — Some researchers have wanted to commercially farm octopus for decades. From trying to raise hatchlings themselves to storing the wild invertebrates in submerged cages, scientists have tried a range of techniques to cultivate watery fields with on-demand access to the elusive creatures.

The closest researchers have gotten is catching wild octopus for a few months of captive rearing before harvest. Today, there are still no functional octopus farms raising the sea creatures from hatchlings in operation — and that’s how some researchers argue things should stay.

In 2019, a handful of scientists started to raise questions about the ethical and ecological issues that might come from farming these remarkably intelligent animals. Speaking up about these concerns before octopus farming becomes a reality was part of the point, says Jennifer Jacquet, an interdisciplinary scientist at New York University. “Our goal was to create that dialogue before [octopus farming] becomes embedded in our society,” she says.

Oversight of fishing vessels lacking, new analysis shows

February 19, 2020 — Policies regulating fishing in international waters do not sufficiently protect officials who monitor illegal fishing, the prohibited dumping of equipment, or human trafficking or other human rights abuses, finds a new analysis by a team of environmental researchers.

“These fisheries observers risk their lives to watch over industrial fishing activities, and yet they are often not afforded sufficient legal safeguards,” says Jennifer Jacquet, an associate professor in New York University’s Department of Environmental Studies and a co-author of the study. “If we are serious about protecting ocean life, we must first put policies in place to protect fisheries observers.”

The analysis, co-authored with the nonprofit Greenpeace and the Association of Professional Observers, appears in the journal Marine Policy.

There are an estimated 2,500 observers globally, and in recent years many have been subject to human rights and safety violations, including intimidation, assault, and even murder or disappearance under suspicious circumstances. The researchers add that since 2010, at least seven fisheries observers have disappeared while monitoring fisheries under the authority of Regional Fisheries Management Organizations (RFMOs). Notably, very little information is available regarding the circumstances.

High seas fisheries play limited role in feeding the world

August 14, 2018 — A recent study undertaken by a team of fisheries and social scientists found that fishing fleets operating outside of national waters contributed to less than 3 per cent of the world’s seafood supply.

Scientists from Dalhousie University, New York University and National Geographic paired a global database of marine catches developed by researchers at the University of British Colombia with a seafood trade database maintained by the United Nations Food and Agriculture Organisation. They analysed the data, considering the amount of fish and marine invertebrates produced by marine capture fisheries and comparing it to those produced by freshwater fisheries and aquaculture.

The team found that a much lower volume of seafood was produced by the high seas fisheries, with most of the catch destined for upscale EU, US and Asian markets. China and Taiwan account for one-third of the total high seas catch.

Lead author Laurenne Schiller, PhD student at Dalhousie University said: “I think many people have the misconception that because the area is so large, the high seas must be contributing a massive supply of food to the world, but that’s just not the case. Only a handful of countries are fishing in the high seas and the fish they catch are not feeding those most in need”.

The findings of this study are against the common misconception that high seas fisheries are important for food security. Less than 40 species are targeted by fisheries in the high seas, and only one species, the Antarctic toothfish, is exclusively caught in this are of the ocean. Marketed as Chilean sea bass, this fish can easily sell for over $50 per kilogram.

Not All Fish Puts You at Risk of Mercury Poisoning

June 7, 2018 — If you’ve ever eaten sushi, you may be familiar with rumors and rumblings about how eating too much can give you mercury poisoning. Pregnant women are typically advised to steer clear of any spicy tuna roll cravings because.

It has to be dangerous to eat too much of a certain kind of fish, right? Well, sort of. Mercury poisoning, and fear of it, is laced with misconceptions, in part because the metal comes in different forms and thus, has different modes of poisoning someone.

Mercury is a natural metal found in the earth, Judith Zelikoff, a professor in NYU’s School of Medicine’s department of environmental medicine, told The Daily Beast. It’s potentially dangerous to ingest because it inhibits inhibits selenoenzymes, which protect the immune system, causing toxicity. Methylmercury is the most common type of organic mercury that is found in the earth and what is commonly in fish that most commonly leads to mercury poisoning. There’s also inorganic mercury, or elemental mercury, that is found in old-school thermometers.

“The problem comes from environmental exposures,” Zelikoff said, pointing to mercury-containing coal combustion as the problem. “So when [coal] is burned and combusted, it gets into the air. Once it’s in the air it falls to the ground, not only to the soil but also to the surface of water and rivers and lakes.

To help stop illegal fishing, ban practice of transshipment on high seas, researchers say

May 2, 2017 — New research concludes that a total ban on the practice of transshipment on the high seas is necessary to help stop illegal fishing and reduce the human trafficking and labor rights abuses that often accompany unlawful fishing activities.

“Transshipping enables fishing vessels to remain at sea for extended periods of time,” Washington D.C.-based oceans conservancy NGO Oceana explains. “Fishing vessels and refrigerated cargo vessels rendezvous at sea in order to transfer seafood, fuel or supplies. While this transshipping practice can be legal in many cases, it also can facilitate the laundering of illegally caught fish, especially on the high seas and in waters surrounding developing and small island nations with insufficient resources to police their waters.”

As detailed in a report released last month, Oceana found that close to 40 percent of suspected instances of transshipping occur on the high seas — areas outside of any national jurisdiction, which make up about two-thirds of Earth’s oceans. Russia’s Sea of Okhotsk, the high-seas regions of the Barents Sea, the national waters of Guinea-Bissau, and just outside the national waters of Argentina and Peru are reportedly the world’s chief transshipping hotspots.

Oceana’s report was based on an analysis of data collected by West Virginia-based environmental monitoring NGO SkyTruth and Global Fishing Watch, a partnership between Google, Oceana, and SkyTruth, which documented more than 5,000 “likely” cases of illegal transshipment and over 86,000 “potential” cases between 2012 and 2016.

In a paper published in the journal Marine Policy last month, a team of researchers make the case that a global ban on the practice of transshipment on the high seas is necessary in order to curb illegal fishing and human rights abuses in the global fishing industry.

“This practice often occurs on the high seas and beyond the reach of any nation’s jurisdiction, allowing ships fishing illegally to evade most monitoring and enforcement measures, offload their cargo, and resume fishing without returning to port,” Jennifer Jacquet, an assistant professor in the Department of Environmental Studies at New York University (NYU) and a co-author of the paper, said in a statement.
