Special Issue Information

Dear Colleagues,

With the intensification of aquaculture production, fish have become more susceptible to stress and, consequently, diseases, making it necessary to develop technologies that reduce these negative impacts and promote greater efficiency in the growth and better health of these animals. Dietary supplementation, whether through the use of essential nutrients such as proteins/amino acids, lipids/fatty acids, carbohydrates, vitamins and minerals or also through non-nutritional compounds, such as prebiotics, probiotics, herbal medicines, plant extracts, etc., has become increasingly important, as many studies have confirmed its benefits on growth performance, immune response, resistance to diseases and well-being in many fish species. Therefore, we invite researchers to submit works that address topics related to the use of dietary supplements and their effects on the growth and health of fish, with the aim of making a significant contribution to expand knowledge about the productive chain of these animals in a global context.

Dr. Gisele Cristina Favero

Additives in fish feeds are used worldwide to provide better productivity and improve fish’s health in facing disease outbreaks. This study aimed to identify the protective effect of taurine on the immune-related parameters and antioxidant enzyme activities of Seriola rivoliana juveniles after being challenged with LPS (lipopolysaccharide). Previously, the fish were submitted to a feeding trial for 60 days with feed enriched with different doses of external taurine (0, 1%, and 2%). Juveniles fed on different doses of taurine were injected with LPS (0%, LPS+T0%; 1%, LPS+T1%; 2%, LPS+T2%), and a control group was injected with saline solution (LPS-). The immune-related mRNA expression was evaluated, as were lysozyme enzyme activity and antioxidant enzyme activities (superoxide dismutase—SOD; catalase). Regarding immune mRNA expression, all the treatments had a peak of expression at 24 h post-LPS-injection, with a sharp decrease at 72 h post-injection, reaching similar mRNA expression as at 0 h post-injection. The results showed that the LPS+T2% treatment improved the expression of il1-β, tnf-α, and tlr-3 at 24 h post-LPS injection. Antioxidant and lysozyme activities were higher in both treatments with taurine when compared to the LPS+T0% and LPS- groups after 72 h post-LPS injection. These results suggest using 2% of exogenous external taurine can improve immunocompetency and counteract the oxidative stress caused by exposure to LPS in S. rivoliana juveniles. Full article

Chinese herbal medicines have become a new green feed additive in the aquaculture industry. The aim of this study is to investigate the effects of traditional Chinese herbal medicines (Isatidis radix, Forsythia suspensa, and Schisandra chinensis) on the growth performance, antioxidant capacity, and intestinal microbiota of hybrid snakehead (Channa maculata× Channa argus ♂). A total of 600 fish (mean weight: 15.85 ± 0.15 g) were randomly assigned to five groups, including the control group (CG), I. radix extract group (IRE), F. suspensa extract group (FSE), S. chinensis extract group (SCE), and the Chinese herbal medicine mixture group (CHMM; a mixture of extracts of I. radix, F. suspensa, and S. chinensis at the ratio of 1:1:1) for 6 weeks. The results show that the IRE-supplemented diet improved the survival rate (SR), feed efficiency ratio (FE), and condition factor (CF) compared to others. Compared to the control group, the activity of superoxide dismutase (SOD) in plasma and intestine was significantly increased in the FSE and CHMM groups, whereas the content of malondialdehyde (MDA) in plasma and liver was significantly reduced in the SCE group. A 16s rRNA analysis indicates that dietary supplementation with FSE significantly promoted the proliferation of Fusobacteriota, while IRE supplementation increased the alpha diversity of intestinal bacteria. In conclusion, the addition of I. radix to the diet of hybrid snakehead improves growth, antioxidant capacity, and liver and intestine health, and modulates the intestinal microbiota of snakehead positively.
