“…Nevertheless, integrated mangrove-shrimp cultivation can help to sequester blue carbon (Ahmed et al 2018). Because of high energy consumption, GHG emissions from recirculating aquaculture systems are higher than other fish culture methods, and are ranging from 7 to 27 kg CO2eq kg -1 live weight fish (Liu et al 2016;Badiola et al 2017). Converting paddy fields to fish farms in China can increase GHG emissions from 8.15 to 28 tons CO2eq ha -1 (Yuan et al 2019).…”

“…Generally, the efficiency of the RAS is enhanced, in order to reduce the amount of energy required to produce a kg of fish, while maximizing the stocking density of the fish (typically 61-122 kg/m 3 , but in some cases, may exceed 545 kg/m 3 ). The system is therefore successfully applied to rear smolts in many salmon producing countries [20]. In Norway, a total of 12-20 million smolt per year are produced under RAS [21].…”

With an estimated global value of US$15.6 billion, farmed salmonids represent a precious food resource, which is also the fastest increasing food producing industry with annual growth of 7% in production. A total average of 3,594,000 metric tonnes was produced in 2020, behind Chinese and Indian carps, tilapias and catfishes. Lead producers of farmed salmonids are Norway, Chile, Faroe, Canada and Scotland, stimulated by increasing global demand and market. However, over the last 2 years, production has been declining, occasioned by effects of diseases as well as rising feed costs. Over the last year, production has declined sharply due to effects of covid-19. This chapter reviews the species in culture, systems of culture, environmental footprints of salmon culture, and market trends in salmon culture. Burden of diseases, especially Infectious pancreatic Necrosis, Infectious salmon anemia and furunculosis, as well as high cost of feed formulation, key challenges curtailing growth of the salmon production industry, are discussed. A review is made of the international salmon genome sequencing effort, selective breeding for disease resistance, and the use of genomics to mitigate challenges of diseases that stifle higher production of salmonids globally.

“…Since the farm is located in the temperate climate region featured by long winter with drastic temperature changes in a day, heating water to maintain the temperature at 28 • C for shrimp is essential, however, electricity consuming. Similarly, Badiola et al (2017) indicated electricity use in RAS for water temperature regulation as the hotspot. Electricity was also used for aeration to increase the dissolved oxygen concentration in water required for shrimp rearing in the closed system.…”

Shrimp is the most popular seafood in the United States; its production plays an important role in the aquaculture industry. However, shrimp farming causes various environment impacts that must be mitigated to ensure the sustainability of shrimp production. This study performed a life cycle assessment (LCA) on two US-based and one Vietnam-based shrimp production chains from cradle to US market covering three farming systems and eight shrimp feed formulae. Midpoint environmental impacts including terrestrial acidification, freshwater eutrophication, and global warming were determined. For the intensive production chain (IPC), feed production was identified as the main contributor to the terrestrial acidification potential (TAP) and global warming potential (GWP), and its freshwater eutrophication potential (FEP) was dominated by shrimp farming. Poultry by-product and fish meals were the feed ingredients contributing high TAP and GWP. However, soybean, wheat, and corn gluten meals produced higher FEP; hence, substituting plant-based proteins for animal-based ones in shrimp feeds did not all have positive environmental consequences. Shrimp farming was the hotspot of all the environmental impacts of the semi-intensive production chain (SPC) and extensive production chain (EPC), except for the TAP of the EPC. Among the three production chains, the IPC had the highest FEP due to the on-farm discharge of phosphorus-containing wastewater, and the SPC caused the highest TAP because of the intensive uses of electricity and fertilizers for pond cultivation. Although the EPC was most sustainable in terms of TAP and FEP, open farming in mangrove areas produced the highest GWP owing to land transformation. This LCA study is expected to serve as US shrimp farmers' decision-making guidelines to adapt farming practices with lower environmental footprint.
