Atlantic Bluefin Tuna: A Fish in Troubled Waters

The decline of Atlantic bluefin tuna is the quintessential example of human overexploitation at sea. In this blog post, I hope to not only identify major threats to this species but examine the historical roots of these threats.


Historically, humans have fished tuna sustainably for centuries: a feat which can primarily be attributed to the relatively low demand and value placed on bluefin tuna. Tuna were initially caught along the Atlantic coast mainly for sport as opposed to consumption. At the very height of tuna sport fishing during the mid-1900s, bluefin tuna still sold for only a few pennies a pound in the United States, and carcasses were often ground into cat food, sent to landfills, or dumped back into the sea (Corson 2008). Even as a food product in Japan, bluefin tuna was unpopular due to the unusually red, smelly, and bloody qualities of the meat, which differed greatly from the mild tasting fish typically consumed by the Japanese at the time, mainly white fish and shellfish (Corson 2008).

After World War II, a drastic shift occurred in the popularity of tuna as advanced refrigeration technology prevented smelly, red-fleshed fish from spoiling and the Japanese began to acquire a taste for rich, fatty red meat, such as beef, from Americans. This resulted in an increased demand for bluefin tuna that also happened to coincide with a period of massive globalization. Japanese planes delivering electronics to the United States began to capitalize on cheap bluefin tuna available in New England to fill up their empty planes on the flight back home, where the tuna was then sold for thousands of dollars. As the popularity of bluefin tuna skyrocketed in the Japanese sushi market, trends in American sushi soon began to follow suit, and by the 1990s, the bluefin tuna was in high demand worldwide (Corson 2008).

Today, sushi is a multibillion dollar industry, and bluefin tuna has grown to have immense market value in the global economy, particularly in Japan. In fact, between 1970 and 1990, fishing for bluefin tuna in the Western Atlantic rose by over 2,000%, while the average price paid to Atlantic fishermen for bluefin exported to Japan increased by 10,000%. One extravagant demonstration of the increasing value of bluefin tuna occurred in 2013, when an owner of a Japanese sushi restaurant chain paid a record $1,763,000 for the first bluefin tuna sold at the renowned Tsukiji fish market in Tokyo (Associated Press 2013).

Unfortunately, the high monetary value in tandem with the increasing rarity of the bluefin tuna has created an anthropogenic allee effect, where the smaller the population of bluefin, the more valuable the rare tuna becomes and the more heavily exploited they are by humans. With Japan consuming approximately 75-80% of the worlds’ catch of bluefin tuna, some major Japanese corporations are prepared to take advantage of this effect (Hamilton et al. 2011). For example, Mitsubishi, a company which handles 35-40% of Japan’s imported Atlantic bluefin tuna, has been deep-freezing and stockpiling thousands of tons of bluefin each year, seeking to profit by selling bluefin at extremely steep prices in the future when the bluefin tuna is extinct or near extinction. With declining populations only accelerating the process of extinction, Atlantic bluefin tuna are a species at significantly high risk.

Major Threats

Overfishing is the single biggest threat to Atlantic bluefin tuna today. The story of human overexploitation of Atlantic bluefin tuna exemplifies a pivotal moment in marine history. After World War II, there was not only a surge of globalization leading to the high demand for bluefin, but also a surge in new war technology that was redirected towards fishing efforts, ultimately leading to a massive expansion and intensification of global fishing (Blackford 2008). Fishing fleets began incorporating sonar and radar to detect fish schools, while special buoys, or fish aggregating devices, were used to attract pelagic fish like bluefin tuna. At-sea freezing technology was also developed, allowing vessels to stay out at sea for longer periods of time and expand their fishing territory. Giant nets called purse seines were introduced to enclose and scoop up entire schools of fish from large sections of the ocean. These purse seines quickly became the most common gear used in the Mediterranean, leading to the emergence of a technologically advanced fleet of purse seining vessels. Despite scientific evidence of overfishing and depleted bluefin tuna stocks, during the period of 2005-2007 alone, the European purse seine fleet doubled in size as more vessels were employed to hunt down dwindling bluefin populations, with subsidies continuing to sustain the EU fishing industry at a rate of more than €800 million per year (Willson 2012). What resulted from these technological advancements in fishing was a new era of industrial scale, commercial exploitation of the sea.

However, not even advanced fishing technology could satiate demand for bluefin, resulting in the boom in illegal, unreported, and unregulated (IUU) fishing. Underneath the surface of the bluefin industry lies a massive black market conservatively valued at $4 billion (Guevara et al. 2010). At its peak between 1998 and 2007, more than 1 in 3 bluefin was caught illegally (Guevara et al. 2010). Illegal practices occur throughout the bluefin industry from fishing vessels and farms to distributors in Japan all the way up to government officials. For example, fishing vessels would illegally catch undersized tuna and hire banned spotter planes to locate schools of tuna from the air (Guevara et al. 2010). Vessels and ranches would deliberately underreport catch data and a market even emerged around trading quotas, where one vessel sells it’s nation’s quota to a foreign vessel that has overfished (Guevara et al. 2010). Giant cargo vessels, or reefers, also pose a significant problem, in addition to ranches, as a means of sneaking in illegal tuna. With a length of over 100 meters, reefers essentially act as floating freezers to store tuna caught by various fishing vessels (Chartier 2013). Reefers have become the perfect loophole to sneak in illegally sourced fish through transshipping, the practice of transferring fish catches from one vessel to another, which often occurs outside of regulated exclusive economic zones (Chartier 2013). As catches are transferred from boat to boat and then aggregated on a single reefer, it becomes increasingly difficult to determine which vessel caught which fish and where.

ICCAT Corruption and Controversy

The primary governing body in charge of Atlantic bluefin tuna is the International Commission for the Conservation of Atlantic Tunas (ICCAT). ICCAT was formed in 1966 to manage the conservation of tunas and tuna-like species in the Atlantic Ocean and adjacent seas (ICCAT 2007). In theory, ICCAT sets yearly total allowable catch limits based on scientific advice provided in stock assessments conducted approximately every two years by their Standing Committee on Research and Statistics (SCRS). However, ICCAT has been infamous for implementing poor management practices, instead referred to by other conservationists as “an international disgrace” and the “International Conspiracy To Catch All Tuna” (Brower 2014).

One of the biggest controversies surrounding ICCAT occurred in 2008 when scientists recommended a total allowable catch of 15,000 mt to maintain the current eastern Atlantic bluefin tuna population and 10,000 mt to work towards population recovery (ICCAT 2009). However, ICCAT decided to set a quota of 28,500 mt with actual catch estimated to be 61,000 mt, or 1/3 of remaining stocks, when accounting for IUU fishing (ICCAT 2009).

Ultimately, the plight of the Atlantic bluefin tuna serves as a significant case study for examining the human relationship with the ocean and revealing a history of overexploitation that extends to marine species beyond bluefin.

Food Sovereignty: A “Re-Peasantization” of Food Systems

Food Sovereignty

“Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. It puts the aspirations and needs of those who produce, distribute and consume food at the heart of food systems and policies rather than the demands of markets and corporations.” – Declaration of Nyéléni, the first global forum on food sovereignty, Mali, 2007

First coined by La Vía Campesina, the International Peasant’s Movement, the concept of “food sovereignty” is one example of the potential to radically transform our current unsustainable, inequitable agroindustrial food system through the empowering of indigenous and peasant communities. While many have looked to science for solutions to our current food crisis, what is really necessary to push for large-scale change is a grassroots social movement that operates outside of our current industrialized, capitalist food system and instead prioritizes the fight against systematic exploitation, oppression, and colonization.

There are several misconceptions surrounding the idea of “world hunger.” For example, many believe that world hunger is caused by the scarcity of food rather than systematic barriers to accessing food. Many others turn to the Green Revolution as the solution to food insecurity with its seemingly revolutionary use of modern technologies such as agrochemicals and transgenic crops.

The truth is, we are currently living in a time when global inequities are at their highest levels with nearly half the planet’s wealth concentrated into the hands of just 80 individuals and a sixth of the world’s population who qualify as “hungry.” In fact, there is an extensive history of “de-peasantization” where small farmers were robbed of their autonomy and intentionally made dependent on green revolution technologies, leading to displacement by foreign companies or governments or trapping them in cycles of debt.

“Our modern food system is a true regime of food apartheid that undermines democratic and community control of our food systems. It does so with privatization/corporatization at the expense of people and the planet for profits.” -Food First

“The food system is built upon land theft and genocide of indigenous people and the exploitation of Black and Brown labor. Black farmers currently operate less than 1% of the nation’s farms, having lost over 12 million acres to USDA discrimination, racist violence, and legal trickery. 85% of the people working the land in the US are Latinx migrant workers, yet only 2.5% of farms are owned and operated by Latinxs. People of color are disproportionately likely to live under food apartheid and suffer from diabetes, heart disease, obesity, and other diet related illness. Labor laws continue to permit the exploitation of farm and food workers.” -Soul Fire Farm

In Food Sovereignty: Global Rallying Cry of Farmer’s Movements, Food First’s Peter Rosset wrote that that “food sovereignty goes beyond the concept of food security… [Food security] means that… [everyone] must have the certainty of having enough to eat each day … but says nothing about where that food comes from or how it is produced.” While food security is often limited to conversations about scarcity of food, food sovereignty takes on a more holistic, preventative approach by tackling the root causes of food insecurity and asking questions about power and control.

The six pillars of food sovereignty are:

1. Focuses on food for people

2. Values food providers

3. Localizes food systems

4. Puts control locally

5. Builds knowledge and skills

6. Works with nature

“Food sovereignty is not just about access to good, healthy food, or about sustainable forms of food production: it is about transforming society.” -Food First

If we are to sustainably increase food production using less land and resources while taking into account an increasingly unstable, unpredictable future caused by the compounding effects of climate change, social unrest, and financial crises, it is vital to incorporate a social justice dimension to food security.

Professor Miguel Altieri of UC Berkeley proposes an alternative agroecological system based on centuries-old socioecological and cultural systems used by indigenous and peasant communities. The current industrial food system uses at least 75% of the world’s agricultural land and most of agriculture’s fossil fuel and freshwater resources to feed barely 30% of the world’s population. In contrast, more than 500 million peasant farms around the world are using less than 25% of the land and almost no fossil fuels or chemicals to feed 70% of the world population.

If we are to envision a food system that is both socially just and environmentally sustainable, it is critical to fight for peasants’ right to their seeds, land, water, and a market of their own.

Food Apartheid

One example of this intersection between social justice and food security is with the shift in language from “food desert” to “food apartheid.” Food justice activist Karen Washington proposes to replace the term “food desert,” areas void of good-quality, affordable fresh food, with the term “food apartheid” to take into account the systematic racism permeating America’s food system.

“I was just in Pennsylvania and North Carolina talking about food deserts, and the topic of food justice and food sovereignty, and putting it out there that it means nothing to me. I asked people to define it, and, of course, they gave me their cookie-cutter definition: “Communities who have limited access to food.” That means nothing. Who in in my actual neighborhood has deemed that we live in a food desert? Number one, people will tell you that they do have food. Number two, people in the hood have never used that term. It’s an outsider term. “Desert” also makes us think of an empty, absolutely desolate place. But when we’re talking about these places, there is so much life and vibrancy and potential. Using that word runs the risk of preventing us from seeing all of those things.

What I would rather say instead of “food desert” is “food apartheid”, because “food apartheid” looks at the whole food system, along with race, geography, faith, and economics. You say “food apartheid” and you get to the root cause of some of the problems around the food system. It brings in hunger and poverty. It brings us to the more important question: What are some of the social inequalities that you see, and what are you doing to erase some of the injustices?” -Karen Washington

Reparations Map for Black-Indigenous Farmers

Another example of an attempt to build a more equitable food system is a digital project created by Soul Fire Farm, a BIPOC (black, indigenous, people of color) centered community farm committed to ending racism and injustice in the food system. This Reparations Map features different farmers of color all over the US seeking reparations: “financial payments made today to help make good on the systemic injustices of the past 400 years.”

“The food system was built on the stolen land and stolen labor of Black, Indigenous, Latinx, Asian and people of color. We are claiming our sovereignty and calling for reparations of land and resources so that we can grow nourishing food and distribute it in our communities.”
