Nutritional Enhancement of Farmed Salmon Meat via Non-GMO Nannochloropsis Gaditana: Eicosapentaenoic Acid (EPA, 20:5 n-3), Docosapentaenoic Acid (DPA, 22:5 n-3) and Vitamin D3 for Human Health

Omega-3 long-chain polyunsaturated fatty acids (n-3 LC PUFAs) and vitamin D3 are essential components of human nutrition. A regular human diet is highly deficient in n-3 LC PUFAs. Fish like salmon are highly recommended in the human diet as they are a major source of high-value n-3 LC PUFAs and vitamin D3. The levels of these nutrients have been decreasing over the last few years in farmed salmon, whose production urgently needs sustainable sources of these nutrients. The microalga Nannochloropsis gaditana (NG) is known for its naturally high potential for the production of eicosapentaenoic (EPA, 20:5 n-3) fatty acid. A commercial diet for Atlantic salmon was supplemented with 1% and 10% of spray-dried NG grown under controlled conditions for a high EPA content. Salmon were harvested on day 49, following which, boneless and skinless salmon meat was recovered from fish and analyzed for the fatty acid profile, total fat, and vitamin D3. Vitamin D3, EPA, and docosapentaenoic fatty acid (DPA, 22:5 n-3) levels were significantly increased (p < 0.05) by supplementing the basal diet with 10% NG, thus, NG represents a novel, functional, natural ingredient and a sustainable source of n-3 LC-PUFAs that can raise the levels of healthy fats and vitamin D3 in farmed salmon meat.

“…They also have great potential to be utilized as raw materials and functional feed additives [18]. Microalgae have good nutritional profiles, which have emerged as good candidates for use in aquaculture [19,20]. Algae can promote growth, stimulate the immune system, and enhance fish color, in addition to utilizing waste-derived nutrients such as nitrate, nitrite, and TAN (total ammonia nitrogen) [21].…”

Most of world’s fish and seafood are produced by aquaculture, which is one of the biggest contributors to the world’s food security. The substantial increase in prices of conventional feed ingredients and the over-exploitation of natural resources are some of the biggest constraints to aquaculture production. To overcome this stress, different approaches and techniques are used, among which the use of non-conventional feed ingredients in the aquaculture sector is the most recent approach. Different non-conventional feed ingredients such as plant-based products, algae (both micro and macroalgae), single-cell protein (bacteria and yeast), and insect meal are currently used in aquaculture for sustainable food production. Amongst all these novel ingredients, insects have greater potential to replace fishmeal. The existence of about 1.3 billion tons of food and agriculture waste from the food chain supply poses a serious environmental threat. Insects are tiny creatures that can thrive on organic waste and thus can convert the waste to wealth by the bioconversion and nutritional upcycling of organic waste. Insects have the potential to recover nutrients from waste aquaculture products, and many fish species feed on insects naturally. Therefore, employing insects in the aquaculture sector to replace fishmeal is an eco-friendly approach. The present review briefly highlights emerging non-conventional feed ingredients, with special attention given to insects. The current review also focuses on the nutritional value of insects, factors affecting the nutritional value of insects, potential insects that can be employed in the aquaculture sector, the physiological response of fish when fed with insect meal, techno-functional properties of insect meal, and emerging approaches for addressing possible downsides of employing insect meal in fish diets. Finally, it suggests avenues for further research into these inventive fishmeal replacements.

“…The partial replacement of sh oil with Nannochloropsis sp. in the form of pure powder biomass or its lipids in feed has led to improvements in the growth and fatty acid pro le of shrimp larvae, post-larvae, and juveniles (Oswald et al 2019;Oswald et al 2020). Also, the partial replacement of sh meal with the microalga in turbot feed increased the concentration of essential amino acids in the meat and improved the organism's antioxidant capacity (Qiao et al 2019).…”

Microalgae of the genus Nannochloropsis are highly valued in aquaculture due to their protein, fatty acid, and carotenoid content, offering potential as additives or substitutes for fish meal or oil. However, large-scale production encounters challenges, particularly concerning the culture medium. Thus, this study aimed to assess the impact of substituting artificial sea salt with common salt and standard medium with agricultural fertilizer in Nannochloropsis oculata production. Initially, the effects of reduced salinity were evaluated at salinities of 30, 10, 5, and 1 ups, followed by an examination of the effects of replacing artificial sea salt with common salt and using agricultural fertilizer on microalgae growth. Salinities of 30 and 10 exhibited the highest growth parameters. The salt source had no significant impact on culture growth, while the agricultural fertilizer enhanced it. Common salt increased the concentration of eicosapentaenoic acid compared to artificial sea salt, although the total lipid concentration was higher in microalgae cultured with artificial sea salt. The developed medium was validated through semi-continuous cultures in 100 L flat vertical bags, showing to be an economically viable alternative without hindering N. oculata growth.
