“…Engle [10] appropriately points out other important logistical considerations that are often overlooked when evaluating new aquafeed ingredients, such as those based on microalgae. These include the importance of considering what impact(s) dietary inclusion of the novel ingredient might have on the functional and rheological properties of combined diet mixtures, finished pellet quality, product shelf-life and how it fits into established complex ingredient distribution and feed processing infrastructure within aquafeed production facilities.…”

Microalgae-based ingredients have potential to ensure continued growth of salmonid a q u a c u l t u r ef o rg l o b a ls u s t a i n a b l ef o o ds e c u r i t yi nt h eb l u ee c o n o m y .A l g a lb i o r e f ineries must valorize the entire crop to grow profitable microalgae-based economies. With massive growth and demand for novel sustainable ingredients, farmed salmonid feed sectors are highly promising areas to focus on. Microalgae-based ingredients for salmonid feeds may have market advantages in terms of lower input costs, aerial footprint, wastewater remediation benefits and carbon credits for industrial CO 2 conversion. A handful of microalgae-based ingredients have been proposed as candidates to supply well-balanced nutrients and immunostimulatory compounds. However, technical gaps exist and need addressing before the industry could economically incorporate microalgae-based ingredients into commercial feeds. Current knowledge on comprehensive biochemical composition is incomplete, highly heterogeneous, and information on their nutritional value is scattered and/or inconsistent. The aim of this chapter is to consolidate relatively fragmented data on biochemical composition and nutritional value of microalgae-based ingredients focusing on farmed salmonid feeds. Presented are discussions on the potential for such 'next-generation' ingredients, opportunities/challenges for their use and a compendium of studies evaluating their performance in feeds for economically relevant farmed salmonids, including rainbow trout (Oncorhynchus mykiss), Arctic charr (Salvelinus alpinus) and Atlantic salmon (Salmo salar).

“…As a result, pig farmers use non-conventional feedstuffs to minimise losses and improve sustainability of these enterprises. Previous studies [1,2,3] concluded that non-conventional feedstuffs are rich in some nutritional components and therefore could be beneficial as pig feed in tropical production systems. However, most non-conventional feedstuffs vary in their dietary composition and this often reflects on finished diets.…”

“…Regarding progress towards the development of novel ingredients, it is imperative to determine the nutritional evaluations of each ingredient, which includes the determination of nutritional value, palatability and feed intake, and digestibility, and requires researchers to conduct nutritional feeding experiments in the lab and feeding/growth trials at commercial farms [ 156 ]. Some ingredients may require additional processing to improve digestibility, the FCR, and reduce the antinutritional factors.…”

Aquaculture, the world’s fastest growing food sector, produces over half of all fish for human consumption. Aquaculture feeds include fishmeal and fish oil, extracted from wild-caught fish such as sardines, and poses ecological, food security, and economic drawbacks. Microalgae, yeasts, fungi, bacteria, and other alternative ingredients show promise as potential ingredients in aquafeeds that provide protein/amino acids, lipids, or omega-3 sources and sources of bioactive molecules. This review article discusses the issues that the literature often lacks data on, such as the recent development of using microorganisms, technological innovation, challenges, and opportunities to develop a low environmental footprint of aquaculture diet. The ingredients often require novel processing technology to improve digestibility and fish growth and reduce antinutritional factors. This is an important gap to fill because microalgae are the most frequently used organism in fish feed, particularly as a dietary supplement or mixed with other ingredients. The production, processing, and formulating steps can affect the nutritional qualities. Stepwise strategies are required to evaluate these ingredients for feed application, and in this article, I articulated the stepwise key approaches of evaluating nutritional and environmental response metrics to develop highly sustainable aquaculture feed using these microorganisms, which would guide a more judicious inclusion of these novel ingredients.
