Summary: In this study, different carbon sources were used to compare the growth performance of giant river prawn postlarvae in a biofloc technology system. It was found that the maize starch treatment had the best feed conversion rate, while the final weight, weight gain, and specific growth rate were similar among the five treatments. Additionally, the maize starch group had higher gross return, net return, and benefit-cost ratio compared to other groups. The highest lipid content was observed in the maize starch bioflocs.

Summary: Integration of tilapia in shrimp biofloc systems can reduce suspended solids and does not compromise shrimp productivity. This study evaluated the effects of different tilapia stocking densities on shrimp growth and system clarification time. The results showed that tilapia densities did not affect shrimp growth and lower tilapia density reduced clarification time.

Summary: Aquaculture is a rapidly growing industry that plays a vital role in providing food for the increasing global population. The integrated multitrophic aquaculture (IMTA) system is a sustainable approach that simultaneously produces multiple aquaculture species using all food levels. By selecting suitable culture species and considering their appropriate population size, IMTA can improve ecosystem health and industry sustainability.

Summary: The results of the experiment indicate that Nile tilapia reared in a biofloc system exhibit better growth, feed intake, and protein efficiency, with higher feed conversion rates. The feed conversion rate is influenced by protein levels and the availability of biofloc, while the apparent digestibility of total protein increases with higher levels of dietary crude protein.

Summary: The global increase in population has raised food demand, leading to aquaculture as a solution to hunger and poverty. However, sustainable aquaculture development is hindered by limited resources and environmental impact. Biofloc technology offers a promising solution with high productivity, reduced resource usage, and minimal environmental impact, making it a viable option for sustainable aquaculture.

Summary: Biofloc technology aims to maximize fish farming productivity by effectively breaking down ammonia and nitrite, promoting healthy flocculation, and enhancing the growth and immunity of cultured animals. Microbial inoculums containing beneficial microbes can significantly improve the water quality, gut health, and immune responses of fish in the biofloc system. This study provides a proof-of-concept approach for assessing microbial inoculums on fish species and developing biofloc technology for sustainable aquaculture.

Summary: The study found that different sources of organic carbon in biofloc systems can affect water quality and microorganism communities, but do not significantly impact the zootechnical performance of juvenile Mugil liza. Liquid molasses was particularly effective in maintaining water quality and reducing water consumption compared to clear water.

Summary: In this study, two nitrifying suspended growth bioreactor processes based on biofloc technology were investigated in recirculating aquaculture systems. The conversion of nitrifying bioreactor to denitrifying biofilter via adding carbohydrates was studied. The results showed that the dominant functional microbes in the nitrifying biofilters were ammonia-oxidizing bacteria, denitrifying bacteria, phosphorus/glycogen accumulating organisms, and nitrite-oxidizing bacteria. The addition of carbohydrates significantly improved the removal efficiency of nitrate and soluble reactive phosphate.

Summary: Water and land scarcity pose significant challenges to aquaculture, but biofloc technology offers a solution by increasing production and promoting sustainability. Tilapia, a highly adaptable species, has been successfully cultivated in biofloc conditions due to its unique characteristics. Factors such as cultivation period, size and stocking density, carbon to nitrogen ratio, and the type of carbon source used impact the growth and immune activity of tilapia in biofloc systems.

Summary: Aquaculture intensification, specifically through recirculating aquaculture systems (RASs) and biofloc technology systems (BFTs), has the potential to contribute to the United Nations Sustainable Development Goals associated with food security. However, the rapid growth of these systems has raised concerns about animal welfare, ecological protection, water treatment effectiveness, and public health. This review explores the influence of macro-infrastructure on the microenvironment in aquaculture tanks and provides insights into improving system performance and environmental management.

Summary: Two laboratory studies with clownfish juveniles Amphiprion ocellaris found that body coloration depends on carotenoid source in the diet and tank background color rather than light spectra. It is recommended to include a minimum of 0.5% astaxanthin in the diet and keep the fish in tanks with a black background to maintain the intense red coloration of the species.

Summary: The study investigated the molecular expression of digestive enzymes in Mayan cichlid larvae during the initial ontogeny, showing that gene activation for digestive organ formation and enzyme secretion is influenced by epigenetic factors such as transition from endogenous to exogenous feeding. This activation leads to increased digestion efficiency and optimal nutrient utilization.

Summary: This study examined the effects of Lactococcus lactis on Macrobrachium rosenbergii postlarvae. The results showed that prawns fed with L. lactis in biofloc and probiotic treatments exhibited better growth and survival compared to the control group. Moreover, the microbial community in prawns' gut and culture water differed among the treatments, possibly due to the colonization capacity of different bacteria in each treatment.

Summary: The use of chitosan in fish diets can enhance the biochemical and immune response in juvenile red tilapia, resulting in higher levels of lipids, triglycerides, cholesterol, carbohydrates, and glucose at lower concentrations, and better protein content at higher levels. Additionally, supplementing with 3% and 4% chitosan showed increased levels of superoxide dismutase and leukocytes in the fish.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
