Fishing of the future: when the ocean becomes a smart farm

Humanity stands on the brink of a new era in its relationship with the sea. World fish and seafood production reached a record 188.2 million tons in 2024, and aquaculture, for the first time in history, surpassed traditional open-sea fishing, providing 103.3 million tons of products. This is not just statistics — it is a turning point that changes everything: from how we catch fish, to how we breed, sell and eat them. The future of fishing is arriving now and will be highly technological, sustainable, and perhaps completely unlike what we knew before.

Blue transformation: how bioeconomics is changing the rules of the game

The main trend that defines the future of the fishing industry is the shift to bioeconomics. As experts at the IX International Fishery Industry Forum emphasize, \"bioeconomics is not a new trend but a course of development for the entire industry, integrating technology, ecology, and economics.\" This refers to a model of business activity based on the use of biotechnologies and scientific knowledge of living systems to increase the efficiency of natural resource use and ensure sustainable development. In other words, the future of fishing is not just resource extraction but reproduction, a deep understanding of ecosystems, and the integration of advanced biological and digital solutions.

The Food and Agriculture Organization of the United Nations (FAO) calls this process the \"Blue Transformation\" — an ambitious program aimed at maximizing the contribution of aquatic products to global food security, combating poverty, and economic development. This means that fish and seafood are no longer just a commodity; they become a strategic resource on which the well-being of billions of people depends. The industry employs nearly 64 million people, and if we consider the entire chain from processing to trade, it provides a livelihood for about 600 million people on the planet.

Aquaculture: from \"addition\" to \"foundation\"

The most significant transformation is happening in aquaculture. For the first time in history, farming operations have produced more fish than was caught in the ocean. This \"turning point\" for the global food system makes aquaculture the main source of fish for humans. And this is not coincidental: farming fish is the most efficient way to transform plant protein obtained in agriculture into high-quality animal protein.

The leader in the industry remains Asia, but production is also rapidly growing in African and Latin American countries. For many rural areas, aquaculture becomes an opportunity to escape poverty and improve their own nutrition. Especially promising are small farms that can provide local communities with fresh fish. According to forecasts, aquaculture should ensure stable growth in production volumes, and the Russian strategy, for example, envisions a growth to 600,000 tons by 2030. The per capita consumption of fish worldwide has already reached a record of 20.7 kilograms per year.

digital ocean: how artificial intelligence and robots are changing the fishing industry

If aquaculture is the \"farm of the future,\" then its \"engine\" becomes digital technology. Fishing and aquaculture are experiencing a profound transformation due to the introduction of artificial intelligence (AI), the Internet of Things (IoT), and big data. Smart technologies become the core of sustainable and high-quality development of the industry.

What does this mean in practice? IoT-based monitoring systems allow real-time tracking of many parameters of the aquatic environment — from temperature and oxygen levels to acidity. Computer vision and machine learning are used to assess biomass, behavior of fish, early detection of diseases, and intelligent feeding. Algorithms can count the number of fish, determine their weight, size, and even differentiate between living and dead individuals.

Underwater robots and automated farms are gradually displacing manual labor. Unmanned aerial vehicles and satellite remote sensing help predict catches, manage stocks, and optimize logistics. Technologies are emerging that allow modeling and optimizing aquaculture processes with the help of \"digital twins\" — virtual copies of real farms. And the blockchain ensures full transparency of the supply chain — from farm to shelf.

Artificial intelligence also helps solve the problem of energy efficiency. New solutions allow to reduce energy consumption by 15-30% through optimizing water circulation, intelligent management of feed, and optimizing routes of fishing vessels. This is not just economy — this is a reduction in the carbon footprint of the entire industry.

Challenges: the flip side of records

However, rapid development of the industry has its downside. Fish farms, if poorly managed, can pollute water, spread diseases, and harm ecosystems. The FAO calls on governments to toughen control and develop eco-friendly farming methods. In addition, about one-third of the world's fish stocks remain overfished, and illegal, unreported, and unregulated fishing removes 8 to 14 million tons of fish annually, bringing $9-17 billion in illegal revenue.

Climate change adds another level of uncertainty. Oceans are warming, water becomes more acidic, fish change their usual migration routes. This has a very negative impact on fishermen and coastal communities that depend on the sea. The FAO report calls for urgent action: from investments in climate adaptation to ending harmful subsidies and fighting illegal fishing.

Future: smart, sustainable, and fair

Despite the challenges, the future of fishing looks optimistic. The demand for sustainable fish will grow, and consumers will increasingly ask questions: how much CO2 was produced during the fishing or farming of this fish, and how does this compare to other sources of protein. Environmental awareness is becoming a new standard.

The way ahead lies in further integration of technology. Biotechnology, digital twins, the Internet of Things, edge computing, and multi-omics (collective analysis of genes, proteins, and metabolites) form a unified system that will allow managing the entire chain — from breeding to processing. A closed-loop intelligent industrial system will be created where each decision is based on data rather than intuition.

It is important that \"smart fishing\" will not only focus on profit. Its main goal is the conservation of water biodiversity, the restoration of ecosystems, and \"green\" management of production. And this is not just words: sustainable management is already yielding results. For example, the fishing pressure in the Mediterranean Sea has decreased by 50 percent since 2013, and fish biomass has increased by 25 percent.

Fishing of the future is not just resource extraction. It is a complex, high-tech, and environmentally responsible system designed to feed a growing population on Earth without destroying the oceans from which life on Earth depends. And this transition has already begun.
