Extensive consumption jeopardizes the future availability of fish as a crucial protein source, leaving no choice but to embrace sustainability.
Global fish consumption has more than doubled from 9.9 kg per person in the 1960s to 20.5 kg per person in 2018. Fish provides about 17% of the world's protein intake, vital for billions of people globally. However, this heightened demand has contributed to overfishing, affecting about 34% of the world's fish stocks—an alarming increase from 10% in the 1970s.
This extensive consumption jeopardizes the future availability of fish as a crucial protein source, leaving no choice but to embrace sustainability. The sustainable fishing industry safeguards marine biodiversity, supports human health, and ensures economic stability in fishing communities. The industry balances seafood demand while conserving ocean ecosystems by adopting responsible practices and protective measures. Promoting and upholding sustainable practices will ensure that future generations can continue to rely on the world's fish resources.
What Is Sustainable Fishing?
The world depends on the ocean, the fish it holds, and the people who manage and protect it. Unfortunately, the ocean is in danger due to ineffective management of our coastal seas, leading to overfishing and other harmful practices. Human-driven issues such as excessive fishing and climate change require solutions.
A behavior-focused and community-driven approach to sustainable fisheries practices is the only way to ensure people's and nature's well-being. Sustainable fishing involves managing and maintaining fish populations at healthy levels to avoid exploiting natural resources. Simply put, fishing is sustainable when it leaves enough fish in the oceans while minimizing impacts on habitats and ecosystems.
While sustainable fishing may refer to different types of fishing—commercial, recreational, or subsistence fishing—they all have one thing in common: sustainable fishing takes people into account. It is about maintaining healthy marine life populations and fisheries for future generations and people's jobs and livelihoods.
Globally, sustainable fishing practices vary widely. The European Union has the Common Fisheries Policy, which aims to ensure that fishing and aquaculture are environmentally, economically, and socially sustainable. In contrast, many developing nations struggle with overfishing due to lax regulations and enforcement.
However, the U.S. fishing industry is one of the most regulated in the world. Its goal is to balance the economic benefits of fishing with the need to protect marine ecosystems. Key regulatory frameworks include the Magnuson-Stevens Fishery Conservation and Management Act, which governs marine fisheries management, and the Marine Mammal Protection Act.
Why is Sustainable Fishing Important?
Climate change significantly impacts oceans and fish stocks' health, making sustainable fishing essential. A healthy ecosystem helps the sea regulate the climate. Carbon dioxide from the air dissolves into seawater, where it gets trapped within different elements of the ocean ecosystem, such as seagrass, the shells of mollusks, and plant-like plankton. Sustainable fisheries maintain biodiversity and healthy ecosystems.
Over a third of global fisheries have been fished beyond sustainable limits, and world demand for seafood continues to grow. Sustainable fishing can reverse this decline and ensure enough fish are left in the sea so that fishing can continue indefinitely.
The long-term health of fish stocks is vital to secure a source of nutrient-rich food to feed a growing population. 16 million more tonnes of seafood could be produced yearly if fisheries are managed sustainably, providing enough protein to meet the needs of 72 million people worldwide.
Certified sustainable wild-capture fishing can also reduce the pressure on land-based agriculture as a source of protein. Seafood also has a lower carbon footprint than land-based animal proteins.
How Can Fishing Be Sustainable?
Several approaches are used to make fishing sustainable, the first of which is a scientific method. Scientists assess how many fish can be caught without harming the ecosystem. This involves gathering data on the stock size, the species' spawning times and locations, and the likelihood of juvenile survival to adulthood. Environmental factors such as predation from other species are also taken into account.
Other measures, such as prohibiting fishing during spawning seasons and establishing size limits to protect juveniles, can be implemented to prevent overfishing. The stock is overfished when too many fish are caught, and more adults are needed to breed and sustain a healthy population.
A critical part of sustainable fishing is using precautionary measures called harvest control rules. These rules require reducing catches if the fish population decreases. This is especially crucial when fish stocks are shared by multiple countries, as it requires a joint effort to avoid overfishing.
Acknowledging the complex relationship between species and their habitats is crucial. This fishing approach prioritizes preserving the overall well-being of the marine environment.
Employing adaptable management strategies that can quickly adjust to changing environmental conditions to integrate the most recent scientific findings.
Sustainable fish farming, conservation-minded fishing, low-impact fishing, and sustainable fishery management are essential for preserving marine ecosystems.
How Does Sustainable Fishing Protect the Environment?
Overfishing and excessive bycatch (any marine species caught unintentionally while trying to catch specific fish) can disrupt the balance of ocean ecosystems, having knock-on effects throughout the food web. Sustainable fishing maintains healthy and diverse ocean ecosystems while minimizing impacts on endangered species.
- A healthy ecosystem benefits fish stocks and helps regulate the climate. With climate change impacting oceans and fish stocks, sustainable fishing is more critical than ever.
- Unsustainable fishing practices can destroy habitat, cause lost fishing gear, and threaten the marine environment. Measures to reduce bycatch, including green fishing gear or modifying it and avoiding fishing in areas where unwanted species are present, are essential.
- Eco-friendly fishing methods like bottom trawling and dredging can be sustainable by avoiding vulnerable areas and using lighter gear to minimize impact on the seafloor.
- Seabird entanglements can be reduced by setting lines and nets deeper in the ocean and fishing at night instead of during the day.
- Preventing lost or discarded fishing gear and reducing its impact, such as using biodegradable materials, can also help protect marine species.
Certification For Sustainable Fishing:
The Marine Stewardship Council certifies fisheries operating sustainably through programs and labels. Its Standard is the leading measure of sustainable fishing. It is rooted in global best practices in fisheries management and widely accepted fisheries science.
An independent third party will assess fisheries volunteers against its standards. To receive the certificate, they must meet principles such as a. sustainable fish stocks, b. minimizing environmental impacts, and c. effective fisheries management.
Once certified, fisheries are audited annually and may be required to improve their practices further to protect marine resources.
Other certification providers are the ASC (Aquaculture Stewardship Council), which denotes responsibly farmed seafood, and BAP (Best Aquaculture Practices), which fortifies the production chain and ensures environmental and social responsibility.
What, As Consumers, Can We Do?
As consumers, we can take several steps to support sustainable fishing practices and contribute to the health of marine ecosystems.
Choose Sustainable Fish to Eat: Remember to select sustainable fish. Wild-caught Alaskan salmon is one of the most sustainable choices because of the strict management practices. Additionally, catfish and tilapia are farmed in the U.S., Canada, and Ecuador. They adhere to strict environmental regulations to minimize impacts on ecosystems. Responsible fish consumption is supported by sustainable fishing regulations, green fishing initiatives, and eco-conscious angling practices.
Look for certifications: MSC for wild-caught seafood or ASC for farmed seafood. These labels indicate that the fish was responsibly sourced.
Opt for variety: Consuming various seafood, instead of just the popular varieties like salmon and tuna, helps reduce pressure on overfished species and supports biodiversity.
Buy local and seasonal: Purchasing locally caught fish in season reduces the environmental impact of transportation and supports local fishing communities.
Educate yourself: Learn which fish species are sustainable, endangered, or overfished. Several apps and websites provide information. For example, Seafood Watch offers recommendations for sustainable seafood consumption.
FishChoice helps businesses and consumers make informed decisions, and the Marine Conservation Society provides guidelines on eco-friendly seafood. You can make more informed decisions and support sustainable fishing practices using these resources.
Reduce waste: Buy what you need and use what you buy. This reduces demand and waste.
Support policies and initiatives: Promote sustainable fishing practices by organizations dedicated to marine conservation. Advocate for stronger regulations and only buy seafood from certified sources.
Spread the word: Share the importance of sustainable seafood choices and responsible fishing practices with friends and family.
Do your bit: By making informed, consumers can ensure fish populations thrive, and marine ecosystems remain healthy for future generations.
