Summary: This study aimed to compare the enrichment capacity of polyunsaturated fatty acids (PUFA) and the long chain polyunsaturated fatty acids (LC-PUFA) of two dipteran species, Hermetia illucens (black soldier fly) and a blowfly, Chrysomya putoria, and its influence on the growth, digestive activities, and immune responses of Nile tilapia. The results showed that the CP larvae had better efficiency in LC-PUFA enrichment compared to BSF larvae, resulting in higher stimulation of fish nutrient utilization processes and a higher growth capacity. All dipteran larval meal stimulated the immune status regardless of the insect species or dietary essential fatty acids.

Summary: High-throughput sequencing was used to study bacterial diversity in a Biofloc aquaculture system and its effect on digestive enzyme activity in Nile tilapia. The study found that the biofloc group had higher bacterial diversity and a different composition compared to the control group. Certain bacterial genera correlated significantly with enzyme activity. The biofloc microbiota provided enzymes that improved digestion and nutrient assimilation in the fish.

Summary: This study aimed to investigate whether xylanase can alleviate the adverse effects on the gut barrier induced by soybean meal in Nile tilapia and to explore the possible mechanism. The results showed that dietary xylanase improved intestinal morphology and decreased the concentration of lipopolysaccharide (LPS) in serum by inhibiting the perk/atf4 signaling pathway and up-regulating the expression of mucin2 (MUC2), which enhanced the gut barrier function of Nile tilapia.

Summary: Fish meal is widely used in aquaculture, but its availability is decreasing and prices are rising. This study found that substituting fish meal with poultry by-product meal had no adverse effect on the growth of Chinese soft-shelled turtles and even improved their performance and health. Therefore, poultry by-product meal can be a viable protein source to replace fish meal in turtle feed.

Summary: The current study showed that increasing the level of insect meal originated from Spodoptera littoralis (SLM) in diets of Nile tilapia resulted in decreased growth performance and lowered lipid content, while feed conversion ratio increased. The inclusion of SLM did not have significant effects on hematological variables, immune responses, and antioxidative indices in tilapia diets, suggesting that it can be used as a partial replacement for fish meal in profitable production of Nile tilapia.

Summary: The activity of enzymes in the digestive tract is crucial for its proper function. Flaxseed and hemp seed, important sources of nutrition, can improve enzymatic activity in the digestive tract and enhance nutritional intake. This study examined the effects of flaxseed, hemp seed, and their combination on various enzymes in the digestive tract of broiler chickens. The addition of flaxseed and hemp seed increased enzyme activities, resulting in improved growth performance. Feeding a combination of flaxseed and hemp seed has economic benefits.

Summary: The emergence of viral diseases in fish, such as tilapia lake virus (TiLV), can cause high mortality and disrupt aquaculture production. A study found that different genetic strains of tilapia have varying levels of resistance to TiLV, with one strain exhibiting a survival rate of nearly 100%. The resistant strain showed lower viral loads and pro-inflammatory responses, suggesting that a stronger antiviral response and reduced pathology contribute to its resistance. These findings suggest the possibility of using TiLV-resistant strains as a cost-effective solution, but integrated measures of biosecurity, diagnostics, and vaccination should still be employed.

Summary: This study analyzed the molecular signatures and phylogenetic relationship of lutjanids in Malaysia and identified five distinct species. Significant genetic structuring was found between different regions of the South China Sea, possibly due to loss of gene flow caused by oceanic currents. However, population and species showed genetic homogeneity between the South China Sea and the Straits of Malacca.

Summary: In this study, the application of Amphora coffeaeformis diatom in the diet of Nile tilapia was found to improve growth performance, enhance immune and antioxidant responses, and control Aeromonas hydrophila infection. The 2% and 3% concentrations of A. coffeaeformis showed the most significant effects. Immunological and antioxidant improvements were maintained even after the challenge with A. hydrophila. The histopathological examination also demonstrated the protective effects of A. coffeaeformis against A. hydrophila infection in various organs of Nile tilapia.

Summary: Nonalcoholic fatty liver disease (NAFLD) affects about 24% of people worldwide and is characterized by increased liver fat, inflammation, and cell death in severe cases. This study aimed to investigate the effects of a high-cholesterol diet on lipolytic gene expression, liver function, lipid profile, and antioxidant enzymes in rabbits, and the potential modulatory effects of Lactobacillus acidophilus (L. acidophilus) probiotics. The findings showed that a high-cholesterol diet induced hepatic vacuolation and upregulated lipoprotein lipase (LPL), hepatic lipase (HL), and cholesteryl ester transfer protein (CETP) gene expression, while downregulating low-density lipoprotein receptor (LDLr) gene expression. Additionally, it resulted in increased liver enzymes, cholesterol, triglycerides, and decreased high-density lipoprotein, total protein, albumin, and liver antioxidants. Probiotic supplementation, particularly L. acidophilus, helped to restore all parameters to normal levels.

Summary: The present study evaluated the effects of long-term salinity stress on juvenile Pangasianodon hypophthalmus and found that higher salinities led to decreased growth, feed intake, and survival rates. Additionally, stress and oxidative stress biomarkers were significantly increased in fish exposed to different salinities, with the highest levels observed in the highest salinity group. Histological changes and pathological lesions were also more pronounced in groups exposed to higher salinities. Based on the findings, it is suggested that P. hypophthalmus can tolerate salinities up to 8, with 4 being the most suitable salinity with no adverse effects on growth and minimal impact on histology and physiological responses.
