The global ocean plays a central role in supporting life on Earth. Oceans cover 3/4 of the planet and contain 80% of all life. Overfishing affects the entire ocean ecosystem. For example, the population of large predatory fish has dropped by an estimated 90% since the industrialization of fisheries in the 1950s.
Overfishing is bad for workers as well as the environment: because fish stocks have been declining, vessels must take longer and longer voyages to find fish, meaning that workers are stuck aboard for long periods of time; declining stocks also make fish processing an increasingly precarious job. You might recall the collapse of the Newfoundland Grand Banks cod fishery in the 1990s: this put between 50 000 and 40 000 people out of work. Fishing is central to the livelihood and food security of an estimated 200 million people. Sustainable fishing matters for the environment, for animals, and for people.
In addition to overfishing, sustainability also concerns the broader environmental impact of fishing processes. For example, if gear is lost during the fishing process or if fishing entails destructive processes, such as the use of dynamite and poisons, this can cause more widespread ecosystem damage. Additionally, some farming processes can cause harm through the spread of farm waste, chemicals, disease and parasites.
Human Rights
Thailand is the third largest exporter of seafood in the world (the country’s seafood industry is worth $7.3 billion USD annually); it is also notorious for crewing fishing boats with slaves trafficked from Burma and Cambodia. A form of bonded labour is typical: in this scenario, trafficked fishermen are sold to fishing boat owners and then must work to pay off a given price (the ka hua). In addition to being enslaved, workers on such ships are exposed to overwork, violence, torture, and even executions at sea. Each year the U.S. State Department produces its Trafficking in Persons (TIP) report. In 2014, that report downgraded Thailand to a Tier 3 ranking due to a lack of improvements. The report revealed that the Thai government ignored instances of human trafficking and even sought to punish those attempting to bring these abuses to light.
Thailand is often used as an example of human trafficking in the fishing industry because of the size of its fishing industry and inaction on the part of its government (regulation of the Thai fishing industry is woefully inadequate).
Nonetheless, this is a problem that exists worldwide. While Southeast Asia is the biggest problem region for slavery on fishing vessels, this is a global phenomenon. Human trafficking is endemic in the fishing industry. Some fishing operations in at least 51 countries crew their ships with slave labour.
To give you an idea of the scope of the human trafficking problem in the fishing industry, I created a table that shows how each of the 10 biggest fish exporting countries (as of 2010) were rated in the 2015 TIP report. Tier 1 countries are those that comply fully with the minimum standards of the Trafficking Victims Protection Act’s (TVPA), while Tiers 2, 2 Watch List, and 3 are all for out of compliance countries but vary according to the level of effort that a country is putting into stopping human trafficking. As you can see, three of the top 5 fish exporting countries does not comply with the TVPA.
