[Paper] Atlantic Salmon: Smolt Production, Growth, and Maturation Effects

The study examines the long-term impact of different smolt production strategies on Atlantic salmon. Researchers investigated how varying freshwater photoperiods and diets, combined with different post-smolt rearing environments, affected mortality, growth, maturation, and the occurrence of melanized focal changes (MFC). The findings suggest that rearing post-smolts on land might compromise fish welfare and reduce harvest yield compared to direct transfer to sea cages. Land-based rearing at higher salinity increased MFC, while specific freshwater photoperiods influenced male maturation. Ultimately, the study emphasizes the complex interplay between freshwater and seawater rearing conditions in salmon aquaculture and calls for further research.

[Paper] AI in Aquaculture: Current State, Challenges, and Future Directions

This research article examines the current state of artificial intelligence (AI) within the aquaculture industry, highlighting its transformative potential and various applications. It identifies challenges currently facing aquaculture, including disease, feed costs, and environmental concerns, and explores how AI can address these issues through monitoring, disease detection, feed optimization, and reproduction management. The review further investigates commercially available AI-enabled products and the obstacles hindering the broader adoption of AI technologies, such as acquisition costs and the lack of technical expertise. Finally, the study proposes future research directions to improve productivity and sustainability in aquaculture systems, emphasizing the importance of making existing AI solutions affordable, reliable, and accessible. The authors conclude that AI can revolutionize aquaculture through continued collaboration between technologists, farmers, and policymakers, emphasizing the need to solve AI adoption challenges before creating new AI applications.REF: Fernandes, S., DMello, A., 2025.

[Report] DNV Marine Aquaculture Forecast: Outlook to 2050

The DNV Marine Aquaculture Forecast report provides projections for the marine aquaculture industry through 2050, examining trends in production, demand, and technology. It forecasts a substantial increase in marine aquaculture production to meet rising global food demand, driven by population growth and changing dietary preferences. The report anticipates shifts in production technologies, with increased adoption of offshore and onshore farming methods, particularly for high-value finfish species. It also addresses sustainability challenges related to feed, space utilization, and biodiversity impacts. The study emphasizes the importance of transparency, traceability, and innovation for the sustainable growth of the marine aquaculture sector. Regional differences in production and consumption patterns are highlighted, with Asia remaining a dominant player. REF: DNV Marine Aquaculture Forecast: Oceans . DNV.

[paper] Mooring Line Breakage Effects on Grid Moored Fish Farms

This research explores the impact of mooring line failures on the structural integrity of Norwegian fish farms, a critical concern as aquaculture expands into more exposed locations. Utilizing numerical simulations with the FhSim program, the study analyzes how breakages in mooring lines affect tension distribution and buoy displacement in both single-cage and multi-cage systems under various current conditions. The findings suggest that while a single breakage might not cause immediate collapse under normal currents, it increases the risk of structural failure and fish escape in harsher conditions.

[Report] Guidelines for Sustainable Aquaculture: A Comprehensive Framework

The FAO's "Guidelines for Sustainable Aquaculture" (GSA) is a comprehensive framework to promote responsible development within the aquaculture industry. It addresses the need to balance economic growth with environmental stewardship and social responsibility. Developed through extensive consultation, the GSA provides guidance for policymakers and stakeholders to create sustainable aquaculture practices. The guidelines emphasize good governance, responsible resource use, and the well-being of aquaculture-dependent communities. Ultimately, the GSA aims to ensure aquaculture contributes to global food security, poverty reduction, and the preservation of aquatic ecosystems for present and future generations.
