“…As a result, previous studies partly support our results regarding growth performance. Man et al (2020) found an increase in fish growth after Spirulina application in Sabah giant grouper (Epinephelus fuscoguttatus × E. lanceolatus), but growth in our study was not significantly increased. Adel et al (2016) found that 10% Spirulina platensis provides the best growth performance and immune responses for great sturgeon (Huso huso).…”

This research was conducted to reveal the effects of dietary Spirulina (Arthrospira platensis) meal on the growth performance, immune responses and resistance against Vibrio anguillarum in European seabass (Dicentrarchus labrax). In the study, the fish (5.74 ± 0.02 g) were fed with control (C) and three different levels (1%, 2.5% and 5%) of Spirulina meal‐containing diets (SP1, SP2.5 and SP5) for 60 days. The adaptive and innate immune responses of fish were determined every 30th day of the study. The results showed that respiratory burst activity (RBA) was significantly elevated on the SP2.5 and SP5 groups on the 30th day of the study. Lysozyme activity (LYS) was increased on the SP1 group on the 30th day and the SP5 group on the 60th day (p < 0.05). Myeloperoxidase activity (MPO) was raised on the 60th day of the SP2.5 and SP5 groups compared with the C (p < 0.05). IL‐1β gene expression increased in the kidney and intestine of fish on the 30th day and in the spleen on the 60th day. IL‐10 gene expression in the intestine of fish fed the Spirulina‐containing diet was elevated at each sampling time relative to the C group (p < 0.05). Elevated IL‐6 activity was determined in the kidney and the intestine on all Spirulina‐fed groups compared with control at both sampling times. Similar to IL‐6, IL‐8 gene expressions were elevated in all Spirulina‐fed groups (p < 0.05). TNF‐α was up‐regulated in the kidney and intestine of all Spirulina‐fed groups compared with the C group on the 30th day of the study (p < 0.05). TGF‐β gene expression was increased in the kidney and intestine of all Spirulina groups compared with the C group on all sampling times. COX‐2 gene expression in the kidneys and intestines of fish fed with Spirulina diets was significantly elevated compared with the C diet at days 60th and 30th respectively. Hepcidin gene expression of all groups was elevated in all tissue samples on the 30th day of the study. The survival rate of fish infected with V. anguillarum was higher in all Spirulina‐fed groups than in the C group. The feed conversion rate and protein efficiency ratio of fish fed with a 1% Spirulina diet was found to be better than those fed with other diets. These results show that up to the 5% inclusion of Spirulina meal in European seabass diets promotes some growth parameters and supports immunity in fish.

“…Feeding rainbow trout juveniles diets with 5% Schizochytrium limacinum biomass increased gut microbial diversity and induced a higher abundance of lactic acid bacteria (LAB) after 15 weeks [91]. An increase in microbial diversity was also found in juvenile hybrid grouper fed diets with 5 or 30% Arthrospira platensis biomass, associated with higher growth at the lowest inclusion level [92]. However, the most promising results have been shown when using macroalgae as alternative protein source.…”

Aquaculture has been challenged to find alternative ingredients to develop innovative feed formulations that foster a sustainable future growth. Given the most recent trends in fish feed formulation on the use of alternative protein sources to decrease the dependency of fishmeal, it is fundamental to evaluate the implications of this new paradigm for fish health and welfare. This work intends to comprehensively review the impacts of alternative and novel dietary protein sources on fish gut microbiota and health, stress and immune responses, disease resistance, and antioxidant capacity. The research results indicate that alternative protein sources, such as terrestrial plant proteins, rendered animal by-products, insect meals, micro- and macroalgae, and single cell proteins (e.g., yeasts), may negatively impact gut microbiota and health, thus affecting immune and stress responses. Nevertheless, some of the novel protein sources, such as insects and algae meals, have functional properties and may exert an immunostimulatory activity. Further research on the effects of novel protein sources, beyond growth, is clearly needed. The information gathered here is of utmost importance, in order to develop innovative diets that guarantee the production of healthy fish with high quality standards and optimised welfare conditions, thus contributing to a sustainable growth of the aquaculture industry.
