Summary: The addition of enzymes in fish feed can enhance the digestibility and absorption of plant- and animal-derived ingredients, leading to increased growth in aquacultural animals. Studies have shown that the use of digestive and non-digestive enzymes can improve the quality of fish feed, but critical steps in the production process should be carefully monitored to ensure enzyme activity is maintained.

Summary: Ornamental fish husbandry faces challenges and losses, such as transport stress and disease outbreaks. This review discusses measures to prevent or control fish diseases and the role of natural and sustainable microbial feed additives (such as probiotics, prebiotics, and synbiotics) in enhancing the health, reducing transport stress, and promoting growth and reproduction of farmed ornamental fish. The review aims to fill the knowledge gap in advanced and sustainable practices in ornamental fish production.

Summary: This study conducted a quantitative analysis to investigate the application effect of spirulina meal in aquaculture feeds. The results showed that the moderate addition of spirulina meal significantly improved the weight, growth rate, and protein utilization of aquaculture animals, while reducing the feed conversion ratio. The growth-promoting effect of spirulina meal as a feed additive was significant, but its effect as a feedstuff was not. The optimal inclusion levels were 1.46%-2.26% for fish diets and 1.67% for shrimp diets. Up to 22.03%-24.53% and 14.95%-24.85% of spirulina meal as a fishmeal substitute did not have a negative effect on the growth and feed utilization of fish and shrimp.

Summary: The aim of this study was to investigate the effects of dietary supplementation with Spirulina platensis on the growth and immunity of Mystus cavasius. The results showed that replacing 7.5-10% of fish meal with S. platensis significantly improved the body weight, growth rate, and immune indicators of M. cavasius. Therefore, it is recommended to replace 7.5-10% of fish meal with S. platensis in the feed formulation.

Summary: Spirulina shows potential as a protein source in poultry and pork production, as well as aquaculture. However, using spirulina as a feed can have implications for system productivity and product quality, depending on the animal production system. Further research should focus on sustainability analysis and product processing and acceptance to investigate the trade-offs of incorporating spirulina into poultry and fish diets.

Summary: The study evaluated the effects of dietary phenylalanine and tyrosine on stress response and metabolism in gilthead seabreams and meagres. Results showed that supplementing diets with these amino acids reduced stress markers in fish, with interspecific differences observed. Additionally, the stress condition led to increased amino acid mobilization towards the brain, particularly in supplemented diets, suggesting a potential use of excess amino acids as energy substrates to cope with stress.

Summary: The aim of this study was to assess the presence of Enterococcus species in ornamental animal feed and characterize their antimicrobial resistance and virulence factors. A total of 103 Enterococcus isolates were recovered from 57 samples of ornamental animal feed, with Enterococcus faecalis and E. faecium being the most frequently identified species. The isolates exhibited high resistance to rifampicin and erythromycin, and many were classified as multidrug-resistant. These findings highlight the public health concern of antibiotic-resistant Enterococcus spp. in ornamental animal feed and the increasing interaction between these animals and humans.

Summary: The phenolic compounds of Spirulina show good antimicrobial activities in fish and seafood products. Studies have shown that these compounds can eliminate and control the growth of pathogenic bacteria and fungi. Therefore, Spirulina as a natural food additive has the potential to combat pathogenic fungi and bacteria.

Summary: The study aimed to test the retention capacity of carotenoids in tissues of Lophiosilurus alexandri juveniles fed diets containing different levels of synthetic astaxanthin. Results showed that the inclusion of astaxanthin did not significantly impact the growth and feed efficiency of the fish. Interestingly, the highest levels of carotenoids in blood and muscle were observed at the 100 mg/kg inclusion level.

Summary: The growing global demand for fish and the stagnation of capture fishery production pose challenges for aquaculture. Aquaculture relies on fishmeal, which is criticized for its environmental impact. To achieve sustainable growth, alternative protein sources such as spirulina are being considered as substitutes for fishmeal. A study conducted in Germany found that informed consumers preferred trout fillets with the unusual yellow color caused by spirulina over conventional white fillets. Additionally, consumers showed a strong preference for domestically-produced fillets and feed claims had a marginal impact on consumer preferences.

Summary: The study identified and localized geological hazards in the construction phase of Ahvaz Subway Line 1 and assessed the environmental impacts in the surface and subsurface sections. The results showed potential environmental hazards at Stations 1, 2, 11, and 12 in the surface section, and the possibility of subsidence in the subway route due to the type of alluvial material and lithology. Seismic stresses and soil corrosion potential were also identified as key factors to consider along the subway route.

Summary: The study investigated the accumulation of heavy metals in contaminated sediments and Sole fish from Musa estuary. Results showed significant differences in metal values between the liver and gill of fish species, with higher metal concentrations found in the liver. Pearson correlation analyses revealed a positive correlation between sediment and fish for metal concentrations. Geoaccumulation index and enrichment factor analyses indicated high pollution with anthropogenic sources in multiple sampling sites.

Summary: Carotenoprotein extracted from Pacific white shrimp processing waste using alcalase and pepsin showed high protein and carotenoid content, with essential amino acids and dominant non-essential amino acids. The extracted samples also contained high amounts of mono and polyunsaturated fatty acids, with differences in fatty acid compositions between alcalase and pepsin extracted samples. Mineral content was significant in the extracted samples, with higher levels of certain minerals in alcalase-extracted samples. The results suggest that carotenoprotein from processing residue of Pacific white shrimp can be used as a valuable and nutritious food or feed powder.

Summary: This research investigated the concentration of heavy metals in the sediments, gill and muscle tissue of Siganus javus, Padina australis, and Sargassum vulgare collected from the Persian Gulf coasts of Bushehr province. The uptake of metals in the gill and muscle tissue followed the trend Cu > Ni > Pb. The study also calculated the estimated daily intake, estimated weekly intake, allowable fish consumption rate limit, and target hazard quotients for the consumption of this fish. The concentration of heavy metals in the edible parts of the fish did not exceed the permissible limits proposed by relevant authorities, but the Ni concentration was higher than standard. The consumer risk indexes for non-cancerous diseases were lower than standard.
