“…The formulation and proximate composition of the experimental diets in the second trial Considering the close relationship between the digestive enzymes and the growth condition of fish (Carneiro et al, 2020), the activity of intestinal digestive enzymes was detected. The results indicated that the activity of intestinal amylase was not significantly different among dietary treatments (p > .05) (Figure 1a).…”

With the development of processing technology, cottonseed protein concentrate (CPC) has been widely used as a new protein source to replace fish meal in aquaculture. But whether CPC can replace soybean meal still needs investigation. A ten-week experiment was designed to evaluate the impact of replacing soybean meal (SBM)[45%], CPC75 [75%] and CPC100 [100%]) on Nile tilapia (Oreochromis niloticus). The results showed that 45% or higher CPC substitution significantly retarded the growth performance. Increased intestinal permeability was found in the CPC75 and CPC100 treatments. To investigate whether the residual gossypol is account for the intestinal dysfunction, an 8-week feeding trial including a control diet (CON), a control diet supplemented with 150 mg/kg gossypol (ML) and 300 mg/kg gossypol (MH) treatments, was conducted. The results showed that the transepithelial resistance (TER) was significantly decreased in MH treatment. In conclusion, the replacement of 30% SBM protein by CPC can be used for Nile tilapia's dietary needs, while 45% or higher CPC substitution of SBM influenced the intestinal health and growth condition of Nile tilapia.

“…cruentum increased activities of digestive enzymes in Penaeus vannamei . The fluctuation of digestive enzyme activity in fish is a direct response to changes in nutrient concentration and food sources, thus modulating digestion and absorption of nutrients (Carneiro et al, 2020). High activities of digestive enzymes can explain the remarkably promoted growth performance of animals (Sun et al, 2020; Zhao, Fang, et al, 2020).…”

The marine unicellular microalga Porphyridium sp. synthesizes several bioproducts consisting of sulphated polysaccharides, arachidonic acid and phycoerythrin, of which sulphated polysaccharides prominently exhibit antiviral, anticancer, anti‐inflammatory, antioxidative and immunomodulatory properties. This study aimed at appraising the feasibility of Porphyridium sp. in diets for Trachinotus ovatus. Three experimental diets were formulated to contain 0 (PS0), 10 (PS1) and 50 g/kg (PS5) Porphyridium sp. powders. After 6 weeks of feeding trials, the supplementation of Porphyridium sp. significantly boosted the growth performance and activities of digestive enzymes (pepsin and lipase). Fish fed with PS1 and PS5 diets showed greater villus length than those fed with PS0 diet. The antioxidant capacity of fish fed the diet with Porphyridium sp. powders was pronouncedly enhanced via stimulating the Nrf2‐ARE pathway and elevating antioxidant enzyme activities. Moreover, Porphyridium sp. supplementation not only promoted liver health of fish by suppressing mRNA levels of pro‐inflammatory cytokines and apoptotic genes, but significantly boosted non‐specific immunity via up‐regulating the mRNA levels of c‐type lysozyme and complement C4 and down‐regulating the mRNA levels of heat shock protein 70. These results suggest that microalga Porphyridium sp. promotes the growth performance and immune function, and thereby strengthens the health of T. ovatus.

“…It has been suggested that an increase of alkaline phosphatase activity can be considered as an improvement of immune status, so the decrease could be considered a negative diet effect [76]. Recently, Carneiro et al [77] replaced fish meal with Chlorella sp. meal in a zebrafish diet, and observed that the increase in alkaline phosphatase activity contributed to improving the overall efficiency of zebrafish juvenile digestive and absorptive processes.…”

Fishmeal (FM) is still the most important protein source in aquafeeds. However, due to the reduction of wild fish stocks used for FM production, its manufacturing it is now unsustainable. Insect meal represents a valid alternative to FM, due to the low carbon footprint of its production and its high nutritional value. The aim of this study was to investigate the potentials of replacing FM with black soldier fly (Hermetia illucens) meal (HIM) in aquafeeds, using zebrafish as the animal model. Four diets were formulated with increasing HIM/FM replacement rate (the control diet contained 20% FM). Mortality rates, growth performances, and feed consumptions were measured, and fish intestine samples were collected for histological and enzymatic analysis. After 49 days, all groups almost tripled their initial body weight (cumulative body weight gain ranged between 143.9 and 155.2 mg), and no statistically significant differences among treatments were observed in relation to growth performances and histological traits. Contrarily, trypsin, alkaline phosphatases, and alpha amylase–glucoamylase activities were significantly reduced when the FM replacement rate was increased. In conclusion, HIM may represent an alternative to FM, since no adverse effects were observed when it was included up to 20% in the zebrafish diet, even when replacing 100% of the FM.
