Your question is too short. what you wish to know as trend? please elaborate

Fish is major diet in world after rice.

The attempt is not only for deep sea fishing but to protect fish from feeding on toxins and chemicals going in their body which in turn is consumed by humans. It is dangerous. Attempts are being made to clean up fish food and areas where fishing is done . Attempts are also being made for genome editing to improve resistance to diseases for fishes of various variety

The "blue transformation" is aimed at integrating fish food in global food security network. Fishes have many healthy ingredients as a food . India is second largest fish exporter with 8% market share and attempts are being made to improve infrastructure , import of healthy fish food for fishes by reducing import duty to 5%.

Here is an excerpt from GOI report

• For the fiscal year 2024-25, the Department of Fisheries received ₹2,616.44 crore, marking a 54% increase compared to the previous year. The Pradhan Mantri Matsya Sampada Yojana (PMMSY) received ₹2,352 crore to bolster the sector's development​Press Information Bureau​India Business Trade
• The Fisheries Infrastructure Development Fund (FIDF) offers concessional financing for aquaculture facilities, processing plants, and export infrastructure

Thank you very much Professor

Dear Doctor

[The 2024 edition of The State of World Fisheries and Aquaculture features the Blue Transformation in action, illustrated by activities and initiatives, led by FAO in collaboration with Members, partners and key stakeholders, to integrate aquatic foods into global food security and sustainability, enhance policy advocacy, scientific research and capacity building, disseminate sustainable practices and technological innovations, and support community involvement.]

[1.World fisheries and aquaculture production hit a new high in 2022. Successful initiatives should be upscaled to consolidate the vital role of aquatic foods for global food security, nutrition and livelihoods. THE STATE OF WORLD FISHERIES AND AQUACULTURE 2024 FAO REPORT : BLUE TRANSFORMATION IN ACTION

2. Aquaculture can meet the rising global demand for aquatic foods. Future expansion must prioritize sustainability and benefit regions and communities most in need.

3. Global capture fisheries production remains stable, but sustainability of fishery resources is a cause for concern. Urgent action is needed to accelerate fishery stock conservation and rebuilding.

4. Global demand for aquatic foods is projected to increase further. Expansion of sustainable production is vital to ensure healthy diets from healthy oceans, lakes and rivers.

5.Aquatic animal production is expected to increase by 10 percent by 2032. The Blue Transformation Roadmap aims to ensure sustainable fisheries and aquaculture growth while promoting equitable benefits and environmental conservation.

6.Small-scale fisheries are a vital source of nutrition and livelihoods for millions of people. Greater global recognition and action are needed to support and empower these communities.

7.Efforts to improve data collection and analysis must be strengthened. They are key to evidence-based policymaking and the effective management of fisheries and aquaculture.

8.Efforts to achieve the Sustainable Development Goal targets related to fisheries and aquaculture must accelerate. FAO urges the international community to step up actions to support implementation of the Blue Transformation Roadmap.]

Current Trends in the Fisheries Business

Currently, global fisheries trade is experiencing significant growth. This is driven by the rising demand for aquatic foods as a source of healthy and sustainable protein. Fisheries products, both from capture fisheries and aquaculture, continue to show increasing export value, especially in developing countries, which are the main suppliers for the global market. The demand for value-added products, such as processed fish and ready-to-eat seafood, is also growing in line with changes in lifestyle and consumer preferences.

In the future, projections indicate that the consumption of aquatic foods will increase by approximately 10% by 2032, particularly in Asia, Europe, and North America. Aquaculture is predicted to become the main contributor in meeting this demand, as capture fisheries stocks tend to stagnate or even decline due to overexploitation.

The Role of Small-Scale Fisheries and Aquaculture

Small-scale fisheries play a strategic role in supporting food security and local economies. Millions of coastal communities rely on small-scale fisheries as their primary source of livelihood. Moreover, this sector contributes around 40-50% of global catch production. However, it faces challenges such as access to markets, technology, and sustainable resource management.

Similarly, aquaculture has become the fastest-growing sector in global food production. It accounts for more than 50% of the total global aquatic food production. Innovative technologies, such as the use of eco-friendly feeds, recirculating systems, and biotechnology, are key to enhancing production efficiency. Aquaculture also plays a crucial role in reducing pressure on wild fish stocks.

Both sectors make significant contributions to food security, nutrition, and poverty alleviation. Small-scale fisheries fulfill the protein needs of local communities, while aquaculture meets the demand of global markets. Additionally, these sectors create employment opportunities, particularly in coastal and rural areas.

Strategies for Sustainable Fisheries Management

To ensure fisheries remain a leading commodity in the food sector, sustainable management strategies are required, including:

By implementing these measures, the fisheries sector can continue to contribute to the provision of high-quality food, job creation, and sustainable economic development.

The latest trend in the fisheries business is the increasing focus on sustainable and eco-friendly practices, such as aquaculture innovation, responsible sourcing, and traceability. Technologies like smart farming, AI for monitoring fish health, and sustainable feed alternatives are gaining popularity. Additionally, there's growing demand for plant-based and lab-grown seafood products, catering to health-conscious and environmentally aware consumers. The industry is also exploring marine conservation efforts to ensure long-term viability while meeting global seafood demand.

Stop ignoring small-scale fisheries in economic models

Economic policies are lacking in data on small-scale fisheries. A team of researchers is determined to change that...

"Small-scale fisheries contribute to the food and nutritional security of a large share of the world’s population. They support the livelihoods of hundreds of millions of people and make vital contributions to the cultural, social and economic cohesion of the communities in which they are embedded. A lack of systematic data collection at the national level renders many of these contributions uncertain. The Illuminating Hidden Harvests initiative begins to fill the gaps.

A collaboration between the United Nations Food and Agriculture Organization (FAO), Duke University, WorldFish and the Stanford Doerr School of Sustainability, the project brings together over 800 experts (researchers, practitioners, government officials, consultants and fish workers) to examine in a systematic way the contributions that small-scale fisheries make to various dimensions of sustainable development at the national, regional and global levels. In this collection, Nature and the Nature portfolio and partner journals present some of the project’s findings, together with opinion pieces on the initiative."

The latest trend in the fisheries business includes the adoption of smart aquaculture technologies such as AI-based monitoring systems, blockchain for traceability, recirculating aquaculture systems (RAS), and sustainability certifications that appeal to environmentally conscious markets, improving both yield and transparency.

The latest trend in the fisheries business includes a strong shift toward sustainable aquaculture, use of digital technologies like IoT and AI for fish tracking and monitoring, eco-certifications to appeal to environmentally conscious consumers, and increased vertical integration to streamline supply chains and enhance profitability.
