Digital Twin technology has emerged to become a key enabling in the ongoing transition into Industry 4.0. A is essence digital representation of an asset that provides better insight its dynamics by combining priori knowledge system through mathematical models with online data acquired from sensors and instruments deployed or at physical asset. While seeing increased use across several different industrial, governmental research sectors, scientific disciplines, application within aquaculture still infancy. However, due rapid development technological methods aquaculture, increasing number building blocks required make for purposes are becoming available. We set out explore these possibilities first defining — what components it should contain, how be constructed, outlining capability levels finished Twin. Our next step was then state-of-the-art technologies thereby identifying current foundation developing this sector. Following this, we developed concrete case studies elaborate upon existing new tools could envision Twins three areas high industrial relevance, namely oxygen conditions sea-cages, fish growth sea-cages in-cage robotics vehicle operations. In conclusion, present our thoughts on potential being component ushering 4.0 outline pathway way onward towards achieving goal.

Offshore aquaculture in China

Reviews in Aquaculture, Год журнала: 2023, Номер 16(1), С. 254 - 270

Опубликована: Май 30, 2023

Abstract The mariculture industry is planning to move offshore due the decline of China's inshore fishery resources, deterioration water environment, inefficient industrial structure and other influencing factors. This article first analyses imbalance between supply demand aquatic products, development space aquaculture supporting policies, thereby concluding that China has significant potential develop aquaculture. Subsequently, status in examined. research progress facilities, marine hydrology, environmental carrying capacity, technology operation equipment are also summarized. Furthermore, problems existing pointed out. On this basis, future ideas for can be planned terms sea area layout, optimized improved seed production systems, pellet feed. relationship ecological protection should coordinated. Additionally, an energy security system built based on clean energy, related industries driven through complementary division labour. present work aims provide a reference promoting China.

Fasting and its implications for fish welfare in Atlantic salmon aquaculture

Reviews in Aquaculture, Год журнала: 2024, Номер 16(3), С. 1308 - 1332

Abstract Periods of fasting occur for a multitude reasons in Atlantic salmon aquaculture. Feed withdrawal is widely used prior to transport, parasite treatments, preslaughter and depuration purposes recirculating aquaculture systems. Voluntary coping response when fish have poor health or are exposed farm environments. Owing increased attention animal welfare aquaculture, concerns been raised regarding ethical issues farmed subjected fasting. However, thorough science‐based recommendations feed‐withdrawal regimes lacking. The purpose this review provide synthesis the various causes evaluate their associated implications so that guidelines appropriate practices can be formulated. To interpret impacts, we describe biological responses tolerance limits consider adaptations wild. Fry parr highly sensitive feed withdrawal. post‐smolts adults well‐adapted endure prolonged without experiencing compromised functionality health. Here, short periods operations should therefore not constitute significant concerns. Serious instead with voluntary may continue weeks. We emphasize environmental extremes exceed appetite impairing thresholds must avoided. Additionally, lead chronic stress induce cessation appetite. Diseases parasites impair also mitigated. Fasting here symptom rather than cause welfare.

Resolving the term “offshore aquaculture” by decoupling “exposed” and “distance from the coast”

Frontiers in Aquaculture, Год журнала: 2024, Номер 3

Опубликована: Июль 5, 2024

The terms “offshore” and “open ocean” have been used to describe aquaculture sites that are further from the coast or in higher energy environments. Neither term has clearly defined scientific literature nor a legal context, often interchangeably. These other related (for example “exposed”, “high-energy”) variously refer aspects of site such as geographic distance shore infrastructure, level exposure large waves strong currents, fetch, water depth, some combination these parameters. ICES Working Group (ICES, 2024) on Open Ocean Aquaculture (WGOOA) therefore identified need define terminology reduce ambiguity for types more precisely, to: (1) promote common understanding avoid misuse different classifications; (2) enable regulators identify characteristics marine site; (3) allow farmers be able assess quantitatively compare development; (4) equip developers producers operational parameters which equipment vessels will operate; (5) provide insurers investors with consistently risk premiums; (6) circumvent emergence narratives root cognitive interpretations public discourse. This paper describes evolution use “offshore aquaculture” most relevant shift definitive robust “exposed can inherently relay clearer information. Adoption this definition “exposed” user than just shore. Key differences importance discussed affect various interest groups. Follow-up articles compilation members WGOOA well scientists outside incorporated develop set definitions rigorous index.

Challenges and potential solutions for the global optimization of "Offshore Wind Energy — Multi-Marine Resources" integration system in the Beibu Gulf of Guangxi

Deleted Journal, Год журнала: 2025, Номер 2(1), С. 100073 - 100073

Опубликована: Янв. 1, 2025

<p>The development of a national energy base and modern system in the Beibu Gulf Guangxi requires an innovative system. General only consists single marine resource, this work introduces "Offshore Wind Energy—Multi-Marine Resources" integration system, which distinctively centers on offshore wind power while incorporating seawater hydrogen production, pumped storage, desalination, aquaculture, other resource utilization complexes. Its potential challenges during its future construction solutions for global optimization that need to be addressed are as follows: 1) creating high-precision speed prediction model across multiple scales; 2) developing under uncertainties; 3) proposing resilience assessment method systems subjected unconventional external shocks. This can contribute comprehensive resources establishment Province around world.</p>
