“…While both products increased the length of the intestine and presumably its absorptive capacity, the higher values were observed for 1% LB Gh . As in other marine fish species 41 , the inclusion of different microalgae in fry 42 and juveniles 43 of the gilthead sea bream increases enterocyte absorption surface. The same effect has been observed through dietary supplementation with Bacillus -based probiotics 44 .…”

The aim of this work was to evaluate two functional feeds for the gilthead seabream, Sparus aurata, containing low inclusion of two microalgae-based products (LB-GREENboost, LBGb; and LB-GUThealth, LBGh). Fish (12–13 g) were fed for 13 weeks a control diet or one of the four diets supplemented with both products at 0.5% or 1%. LBGb and LBGh did not affect specific growth rate or survival, but increased feed efficiency by decreasing feed intake and enlarging the intestines. LBGb increased hepatosomatic index and reduced cortisol levels in plasma, while both products lowered plasma lactate. Extensive metabolite and metabolic enzyme profiling revealed that microalgae supplementations, especially 1% LBGh: (i) decrease plasma lactate and increase hepatic glycogen, (ii) reduce hepatic gluconeogenesis, (iii) enhance hepatic lipogenic activity and lipid secretion, (iv) led fish to double triglyceride content in muscle and to stimulate its lipid oxidative capacity, and (v) increase the content of monounsaturated fatty acids and the omega-3 alpha-linolenic acid in muscle. This study demonstrates that both microalgae-based products are suited to improve feed efficiency and orchestrate significant changes in the intermediary metabolism in gilthead seabream juveniles.

“…As for the other ingredients included in the EMERG diet, macroalgae inclusion at levels of 50 g/kg, similar to the ones used in the current study, did not affect growth and FCR in gilthead seabream juveniles, but reduced the amount of intestinal proteases (Vizcaíno, Mendes, et al, ). Concerning microalgae, dietary inclusion of Scenedesmus does not seem to cause any adverse effect on gilthead seabream (Vizcaíno et al, ), but other microalgae ( Tetraselmis suecica and Tisochrysis lutea ) resulted in negative effects (Vizcaíno, Saéz, et al, ). Data on the digestibility of each individual microalgae species are still clearly needed.…”

“…Data on the digestibility of each individual microalgae species are still clearly needed. Contrary to previous studies (de Cruz et al, ; Vizcaíno, Saéz, et al, ), the current study used a diet containing a mixture of different microalgae at higher percentage levels, while fishmeal inclusion levels were kept to a minimum (50 g/kg). This may be a possible explanation for the reduced growth and nutrient digestibility found in fish fed the EMERG diet.…”

“…Data on the digestibility of each individual microalgae species are still clearly needed. Contrary to previous studies (de Cruz et al, 2018;Vizcaíno, Saéz, et al, 2016b), the current study used a diet containing a mixture of different microalgae at higher percentage levels, while fishmeal inclusion levels were kept to a minimum (50 g/kg). This may be a possible explanation for the reduced growth and nutrient digestibility found in fish fed the EMERG high inclusion levels of dietary poultry meal (Wang et al, 2015), but similarly to our study, feeding giant croaker (Nibea japonica) on a diet based on poultry meal and feather meal did not increase phosphorus losses (Wu et al, 2018).…”

Alternative formulations for gilthead seabream diets: Towards a more sustainable production

To support the expected increase in aquaculture production during the next years, a wider range of alternative ingredients to fishmeal is needed, towards contributing to an increase in production sustainability. This study aimed to test diets formulated with non‐conventional feed ingredients on gilthead seabream (Sparus aurata) growth performance, feed utilization, apparent digestibility of nutrients and nutrient outputs to the environment. Four isonitrogenous and isoenergetic diets were formulated: a control diet (CTRL) similar to a commercial feed and three experimental diets containing, as main protein sources, plant by‐products, glutens and concentrates (PLANT); processed animal proteins (PAP); or micro/macroalgae, insect meals and yeast (EMERG). Diets were tested in triplicate during 80 days. The EMERG treatment resulted in lower fish growth performance, higher FCR and lower nutrient and energy retentions than the other treatments. The lowest protein digestibility was found for the EMERG diet, which caused increased nitrogen losses. The PLANT and PAP treatments resulted in better fish growth performance, higher nutrient and energy retentions, and lower FCR than the CTRL treatment. The significant improvement in FCR found for fish fed PLANT and PAP diets and the high protein digestibility of these diets contribute towards minimizing the environmental impacts of seabream production.

“…Gilthead seabream ( Sparus aurata ) is an important species for Mediterranean aquaculture, with carnivorous feeding habits. Information regarding the effects of microalgae supplementation in gilthead seabream juveniles diets is limited (Cerezuela, Fumanal, et al, ; Cerezuela, Guardiola, González, Meseguer, & Esteban, ; Cerezuela, Meseguer, & Esteban, ; Reyes‐Becerril, Guardiola, Rojas, Ascencio‐Valle, & Esteban, ; Vizcaíno et al, , ), and, to our knowledge, only one study addressed Nannochloropsis sp. inclusion in gilthead seabream diets and its effects were evaluated only at the immune response level (Cerezuela, Guardiola, Meseguer, & Esteban, ).…”

Nannochloropsis gaditana was tested as functional ingredient in low fishmeal diets for gilthead seabream juveniles, and its short‐term effects were evaluated in terms of intestinal morphology, digestive function, intestinal immunological and oxidative status, and intestinal microbiota. A diet with 850 g/kg of the protein provided by plant feedstuffs and 150 g/kg provided by fishmeal was used as control, and three other diets identical to the control were supplemented with 5, 7.5 and 15 g/kg N. gaditana meal and fed to 56.6 g fish for 37 days. At the end of this period, intestinal mucosa integrity and digestive capacity (luminal enzyme activity and absorption) were not altered by dietary microalgae supplementation. Intestinal transcript levels of key markers of inflammation (IL‐1β and TNF‐α) and of key enzymes involved in redox homeostasis (CuZnSOD, MnSOD and catalase) were also similar across experimental groups. However, microbiota richness increased with dietary supplementation of microalgae, and such modulation requires further investigation, particularly regarding its potential effects on disease resistance at short and long term.
