Abstract The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in future. Its role for food security, nutrition, livelihoods, economies, cultures is not clearly visible Agenda 21 declaration. This may partly reflect state of development policies compared with its terrestrial counterpart, agriculture, possibly also because production has historically originated from a few key hotspot regions/countries. review highlights need better integration global system dialogues. Unpacking aquaculture's functions generation values at multiple spatiotemporal scales enables understanding present future potential contribution to SDGs. Aquaculture unique that encompasses all aquatic ecosystems (freshwater, brackish/estuarine, marine) tightly interconnected through, example, feed resources other dependencies. Understanding environmental, social, economic characteristics multifaceted nature provides more context‐specific solutions addressing both opportunities challenges development. includes rapid literature survey based on how links specific SDG indicators.

Abstract Feed‐food competition is the allocation of resources that can be used to feed humans animal instead, a current but unsustainable practise not well documented for aquaculture. Here, we analysed feed‐food in aquaculture using two measures; natural trophic levels (TLs) and species‐specific human‐edible protein conversion ratios (HePCRs). The HePCR equals ratio human edible (input) produce (output). To provide prospects on aquaculture's potential convert inedible by‐products into biomass, data production were collected categorized based TLs. HePCRs computed four species produced intensive systems: Atlantic salmon, common carp, Nile tilapia whiteleg shrimp. Under use, estimated shrimp considered net contributors by requiring ~0.6 kg 1 fillet/meat. Considering soya bean meal fishmeal as food‐competing ingredients increased ~2 turned all case‐study consumers protein. prevent this increase, use high‐quality such fishmeal, or products should minimized feed. In future, role circular food systems will most likely consist balanced mix at different TLs from systems, depending available.

Abstract A circular economy is considered one way to reduce environmental impacts of human activities, by more efficient use resources and recovery, resulting in less waste emissions compared linear take‐make‐dispose systems. Muscat et al. developed five ecological principles guide biomass towards a economy. few studies have demonstrated benefits applying these land‐based food systems, but date, not been explored aquaculture. The current study expands on provides narrative review (i) translate them aquaculture, while identifying implications for the main species production (ii) identify pathways make aquaculture circular. We show that underlying concepts ‘safeguard’, ‘entropy’, ‘recycle’ well researched sometimes implemented. In contrast, ‘avoid’ ‘prioritise’ much less; doing so would provide an opportunity decrease at food‐system level. One example prioritising contribute nutrition security, low thinking wider system scale avoid feed‐food competition identified six priorities could circular: increase demand most essential species, loss farm post‐harvest stages, (iii) support nutrient recycling practices multiple scales, (iv) adapt aquafeed formulations, (v) inform consumers about trophic levels other environmentally friendly aquatic foods, (vi) address urgent research gaps.

Fish, constantly exposed to environmental stressors due their aquatic habitat and high metabolic rates, are susceptible oxidative stress. This review examines the interplay between stress fish reproduction, emphasizing potent antioxidant properties of astaxanthin. Our primary objective is highlight astaxanthin's role in mitigating during critical reproductive stages, leading improved gamete quality, ovary development, hormone levels. We also explore its practical applications aquaculture, including enhanced pigmentation overall health. conducted a comprehensive literature review, analyzing studies on impact reproduction. Astaxanthin, carotenoid pigment, effectively combats reactive oxygen species, inhibiting lipid peroxidation maintaining membrane integrity. It significantly enhances success improves health aquaculture settings. reveals multifaceted benefits offering economic advantages aquaculture. Future research should delve into species-specific responses, optimal dosages, long-term effects astaxanthin supplementation inform sustainable strategies.
