In this study, we used Asian seabass (Lates calcarifer) with initial weight of 29.0 ± 1.0 g as the model organism to investigate the effects of dietary Sargassum ilicifolium and Padina australis on various aspects of growth and immune response. We formulated three diets in which fish meal (FM) was gradually replaced by S. ilicifolium (SIM) and P. australis meal (PAM) at a substitution level of 6% (SIM 6 (S6) and PAM 6 (P6)). The control diet (C) did not contain any macro algae. Our findings revealed that the group given the P6 diet exhibited significantly higher growth and feed utilization than the control group (P < 0.05). Our findings indicate that the inclusion of P. australis in the diet had a significant impact on red blood cells (RBC), haemoglobin (Hb), hematocrit (Hct), white blood cells (WBC), lymphocytes, neutrophils, and cholesterol (P < 0.05). Furthermore, the S. ilicifolium diet resulted in significantly higher levels of total protein and triglyceride in the fish as compared to the other groups (P < 0.05). Our study showed that the group fed with 6% P. australis had significantly higher levels of immunoglobulin and lysozyme in both skin mucus and serum compared to the control group (P < 0.05). Furthermore, the group fed with 6% S. ilicifolium exhibited significantly higher levels of serum immunoglobulin (P < 0.05). However, there were no significant differences in alternative complement activity and serum lysozyme among all treatment groups (P > 0.05). After evaluating the activity of digestive enzymes, including protease, lipase, and amylase, we observed no significant differences among the treatment groups (P > 0.05). Additionally, we measured the expression levels of growth-related genes, such as insulin-like growth factor I (IGF-I), lysozyme (LZ), and interleukin-1β (IL-1β). Our findings indicate that the P6 group had significantly higher expression levels of these genes compared to all other treatment groups (P < 0.05). In conclusion, our research demonstrates that incorporating Padina australis into the diet of Asian seabass juveniles and partially replacing fish meal has positive effects on their immune system and growth performance.

In the present study, Asian seabass (Lates calcarifer) with an initial mean body weight of 29.0 ± 1.0 g (in your materials and methods -31.0 g- which one is correct?) has been used as a model organism to establish the effects of dietary of Sargassum ilicifulium and Padina australis, as partial substitution of fish meal on growth performance, body composition, hemato-immunlogical response, digestive enzymes and immune and growth-related genes. Three diets were formulated in which fish meal (FM) was gradually replaced by S. ilicifolium (SIM) and P. australis meal (PAM) at 6% (S6 & P6, respectively) whereas in the control diet (C), FM was not replaced with macroalgae. Asian seabass juveniles were fed for six weeks with experimental diets. At the end of the experiment, growth and feed utilization parameters in P6 group were significantly higher than those of the control group (P < 0.05). The P. australis dietary supplementation showed differences significantly in RBC, Hb, Hct, WBC to write in full during 1st mention, lymphocytes, neutrophils, and cholesterol contents (P < 0.05). It was observed that the levels of total protein and triglyceride in fish fed S. ilicifulium diet significantly increased compared to the other groups (P < 0.05). The skin mucus total immunoglobulin (Ig) and mucus lysozyme in the group fed on P6 were significantly higher than the control group (P < 0.05). The serum total Ig in the group fed on S6 was significantly higher with respect to the control group (P < 0.05). No significant differences were recorded in the contents of ACH50 in full during 1st. mention and serum lysozyme among all treatment groups (P > 0.05). There was no significant difference in the contents of protease, lipase, and amylase among all treatments (P > 0.05). At the end of the experiment, the insulin-like growth factor I (IGF-I), lysozyme (LZ), and interleukin-1β (IL-1β) in P6 were significantly higher than other treatments (P < 0.05). The results obtained in the present study showed that P. australis as a partial replacement for fishmeal in the diet of Asian sea bass juveniles is beneficial for its immune system and growth performance stimulatory effects.

Eucheuma cottonii has been extensively studied in the field of aquaculture due to its potential as a natural immunostimulant. In this review, we explore the impact of using Eucheuma cottonii as an immunostimulant in aquatic animals. Based on recent literature, we conclude that Eucheuma cottonii can enhance the immune response in aquatic organisms, including increasing Total Haemocyte Count, phagocytic activity, and gene expression related to the immune system, thus enabling aquatic organisms to combat bacterial and viral infections. The mechanism of action of Eucheuma cottonii is believed to involve bioactive compounds such as sulfated polysaccharides that stimulate non-specific immune responses. The implications of using Eucheuma cottonii in aquaculture include the potential to improve the health and production performance of aquatic animals. However, challenges such as quality control of extracts, interspecies effectiveness, and potential environmental risks need to be addressed. Suggestions for further research include a deeper understanding of the mechanism of action, comparative studies among species, development of production technologies, environmental risk management, as well as education and training for aquaculture farmers. With careful and sustainable approaches, the use of Eucheuma cottonii as an immunostimulant has the potential to enhance the sustainability of the aquaculture industry and the overall health of aquatic animals.
