The contribution of aquaculture systems to global aquaculture production

Abstract

Since 2000, aquaculture became well‐integrated into the global food system. Aquaculture systems are highly diverse, producing globally equal amounts of fed and extractive species. In Asia and Africa, inland aquaculture provides the bulk of aquaculture production, while in the Americas, Europe, and Oceania, marine aquaculture dominates. The realized growth of annual production since 2000 is due to intensification, the use of more and better feeds, improved production management, and increased attention to biosecurity. Fed and extractive aquaculture, both need to pay more attention to scaling, site selection, and the health of the wider production environment. In terms of land use, aquaculture is more efficient than terrestrial animal production. Still, water use remains a challenge. More attention should be given to water recycling in land‐based systems, reducing water consumption and facilitating nutrient recovery and reuse. Future development should focus on making aquaculture climate neutral and on reducing environmental impacts, both inland and at sea. More attention must be given to making aquaculture an important part of local food systems on all continents, as is the case in Asia today. Integration of aquaculture into local nutrition‐sensitive, circular, and sustainable food systems should become the major driver for future aquaculture system development.

Partial Replacement of Fishmeal with Seafood Discards for Juvenile Penaeus japonicus: Effects on Growth, Flesh Quality, Chemical and Fatty Acid Composition

“…In the present study, the n-3/n-6 ratio was lower than this value in all the experimental groups. 2 Total SFA-saturated fatty acids (C12:0 + C14:0 + C16:0 + C17:0 + C18:0 + C20:0); 3 Total MUFA-monounsaturated fatty acids (C16:1 n7 + C16:1 n9 + C18:1 n9+ C20:1 n9); 4 Total PUFApolyunsaturated fatty acids (n-6 + n-3); 5 Total n-6 (C18:2 n6 + C18:3 n6 + C20:4 n6 + C22:5 n6); 6 Total n-3 (C18:3 n3 + C20:5 n3 + C22:5 n3 + C22:6 n3); Means having different superscripts within the row are significantly different; a, b : p < 0.05. Likewise, the concentration of C20:1n-9 was significantly (p < 0.05) higher following the control and 25% fishmeal replacement diet, while the percentage of total monounsaturated fatty acids (MUFAs) did not differ among groups.…”

“…The shrimp aquaculture industry has grown rapidly in recent decades and represents the most important aquaculture sector in Europe [1,2]. Consumer shrimp demand has increased in recent decades, leading fish nutrition experts to study the inclusion of vegetable by-products in aquatic animal feeding [3][4][5].…”

Horticulture Irrigation Systems and Aquaculture Water Usage: A Perspective for the Use of Aquaponics to Generate a Sustainable Water Footprint

“…These ecological impacts are the over usage of natural resources due to aquaculture production, being two of the biggest problems the high use of freshwater [101] and the water pollution because of untreated wastewater discharges into the environment [102] which is causing a high impact for the ecosystem [103]. Inland aquaculture food production has a high freshwater consumption rate and has a high dependency on nearby natural water resources [104] and requires nearby water streams, lakes or groundwater deposits [105].…”

Influences of the Integrated Rice-Crayfish Farming System with Different Stocking Densities on the Paddy Soil Microbiomes

“…With the ongoing global population increase, food security has emerged as a critical worldwide challenge. Rice and aquatic products, as fundamental food sources, are pivotal to addressing this issue [1][2][3]. Recent advancements in agricultural production patterns, notably integrated rice-fish farming, have brought significant improvements in sustainable agricultural production and adequate food supply [4,5].…”
