Abstract The aquaculture industry requires good water quality for its successful operation but produces wastes that can cause environmental deterioration and pose high risks to the sector. Adequate waste treatment recycling are necessary make a sustainable profitable contribute circular economy. Polluted sources, excess feeding, overstocking, use of antibiotics/chemicals harmful algal blooms major causes low production in systems. Discharges untreated would have serious impacts on receiving bodies, eventually itself. Possible solutions include technological innovations environmentally friendly systems, efficient processes management improved legislation governance. Environmentally feasible technologies such as system, integrated multi-trophic aquaponics including features viable options schemes. Best practices integrating advanced technologies, supported by automation sensors, modeling artificial intelligence-internet things environment, stable value chain. In general, low-cost impact reduction through governance crucial achieving sustainability natural management.

Feeding an expected global population of 9 billion by 2050 is a daunting challenge that engaging millions farmers, food processors, traders, researchers, technical experts, and leaders the world over. Fish other aquatic products from aquaculture can will play major role in meeting dietary demands all people, while also security needs poorest. Recognizing critical importance aquaculture, need to exchange discuss reliable information further enhance its contribution sustainable development, Food Agriculture Organization United Nations (FAO), at request Members, collaborated with Network Aquaculture Centres Asia-Pacific (NACA) Ministry Rural Affairs People's Republic China, organize Global Conference on Millennium +20 (GCA +20), September 22–25, 2021 Shanghai, China.

Societal perceptions of aquaculture: Combining scoping review and media analysis

Reviews in Aquaculture, Год журнала: 2024, Номер 16(4), С. 1879 - 1900

Опубликована: Май 27, 2024

Abstract Aquaculture has been recognised for achieving multiple United Nations Sustainable Development Goals; its further growth depends on understanding, and responding to, societal perceptions in a broader context. Thus, this study aims to understand of aquaculture through scoping review media analysis. A identified 151 academic studies inclusion our five research clusters: (1) social acceptability, (2) development, (3) coverage, (4) sustainable aquaculture, (5) consumer perceptions. Further, newspaper articles ( n = 100) were sampled from the Kingdom, Denmark, France, Spain, Turkey, China; elsewhere all included (Poland, 79; Hungary, 29; India, 70). The findings suggest that scientific tend present sustainability aspects simplified form. Key stakeholder groups include fish farming enterprises, civil society, governmental officials, scientists, business leaders both within value chains (retailers/wholesalers, technology industry) outside them (fisheries, tourism). Also, other stakeholders public (indigenous groups, residents, consumers). perceived differently depending circumstances context, their ranged positive negative. Many factors influenced perceptions, including aquaculture's impact dimensions, knowledge, transparency, personal interests, types, location practises, regulations, experience, sociodemographic characteristics such as age, gender, education, income. We recommend practitioners focus context‐specific multifaceted strategies—prioritising communication, accountability—and provide essential knowledge ensure are based accurate, empirical information.

Zero hunger: future challenges and the way forward towards the achievement of sustainable development goal 2

Abstract Since 2020, the progress towards achievement of Sustainable Development Goal (SDG) 2– Zero Hunger has faced a sudden stall due to an ongoing “polycrisis”. While some countries are on track, great effort is still globally necessary achieve SDG2 targets. Here we provide brief background about SDG2, including its synergies and trade-offs with other SDGs. We then identify discuss main challenges that pathway zero hunger will have tackle. The lack systemic approach, together complex, global, nested dimensions food systems identified as key elements be carefully considered when designing sustainability strategies. This means variety stakeholders called simultaneously cooperatively act multiple fronts ensure safe, equal, just all populations SDG2.

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.
