Summary: The study indicates that thyroid hormones play a crucial role in the adaptation of Mozambique tilapia to freshwater environments by interacting with branchial deiodinases to modulate their activities. External osmotic conditions do not directly affect the gene expression of branchial deiodinases, while systemic signals may stimulate thyroid hormone metabolism.

Summary: The presence of gut microbiota, especially arsenic-resistant bacteria such as Stenotrophomonas maltophilia, plays an important role in the accumulation and transformation of arsenic in fish. Removing the gut microbiota through antibiotic treatment significantly reduces the levels of total arsenic and arsenobetaine in the intestines and muscles of fish. Arsenic exposure alters the composition of the fish gut microbiota, with S. maltophilia becoming the dominant species. In vitro experiments demonstrated that the gut contents of untreated fish can metabolize arsenate to arsenite and organoarsenicals, while antibiotic-treated fish lose this ability.

Summary: This paper introduces a new classification approach based on swarm optimization to investigate the effects of ammonia concentration on fish protein level and bioactivity, with the aim of guiding decision-makers to review the fish's pathophysiological status. By applying the MFO-SVM method, revolutionary advances have been achieved, outperforming other machine learning approaches.

Summary: This study evaluated the effects of dietary supplementation with L-carnitine on growth performance, gut and muscle histological parameters, blood hematology, plasma biochemical parameters, and antioxidant enzymes in Nile tilapia juveniles. Results showed that supplementation with L-carnitine improved growth performance and reduced lipid content in the filet, while also increasing the activity of the enzyme catalase in the liver. Different inclusion levels of L-carnitine had varying effects on weight gain, fat deposition, and triacylglycerol in the fish.

Summary: This study evaluated the influence of tilapia production in cages on the presence of GSM and MIB in water and sediment. The findings suggest that eutrophication caused by fish farming and inadequate governmental policies lead to off-flavors in fish products.

Summary: This study analyzed the characteristics of three types of tilapia scale gelatins. The results showed that they had good gel strength, foaming properties, and emulsifying properties. Compared to mammalian gelatins, tilapia scale gelatins exhibited better performance and could be used as a potential alternative.

Summary: Despite the enormous potential of tilapia farming in Bangladesh, its culture has yet to become established due to socio-economic, technical and marketing constraints. Lack of capital to invest in tilapia farming and high feed prices were identified as the most critical constraints. Education, farm size, and experience in fish farming were significant determinants to the degree of constraints in tilapia farming.

Summary: This study found that the co-exposure of microplastics and triclosan enhanced the bioaccumulation of triclosan in tilapia tissues. Metabolomics analysis showed that microplastics mainly disturbed lipid and energy metabolism in fish. However, triclosan had a stronger impact on lipid and energy metabolism.

Summary: This study assessed the use of Ocimum americanum and Lippia alba essential oils as anaesthetics in Nile tilapia, showing that Ocimum americanum oil induced deep anaesthesia faster than Lippia alba oil and resulted in higher sensory scores for fillets. The essential oils were effective in inducing deep anaesthesia, providing a potential alternative to hypothermia for fish pre-slaughter handling in Brazil.

Summary: The study evaluated the impact of regulation on antimicrobial resistance in bacteria isolated from fish. It found significant differences in resistance levels within and between semiregulated and unregulated fish value chains, suggesting the need for improved practices and management to reduce the risk of transmitting resistant bacteria to consumers.

Summary: Aquatic collagens have gained attention as alternative sources of mammalian collagen due to their low-cost, low-antigenicity, biocompatibility, and biodegradability. A study examined pepsin-soluble collagens from the skins of Oreochromis mossambicus and Gadus macrocephalus, revealing their potential applications in tissue engineering as biomedical materials. The collagens showed similar triple helical structures and good biocompatibility, and promoted cell proliferation.

Summary: Tilapia tilapinevirus (TiLV) is a newly emerged virus that causes a novel disease and reduces tilapia populations worldwide. It has been reported in 17 countries, causing high mortalities. Currently, there are no therapeutics or vaccines specifically designed for TiLV control. Vaccination has shown potential in inducing protective immunity in tilapia. Various vaccine strategies are being explored, but a comprehensive overview of their efficacy is lacking. This review discusses recent advances in TiLV vaccine development, highlighting the need for further research and the incorporation of different approaches to enhance vaccine effectiveness.

Summary: The study investigated the effects of antioxidants on the physicochemical stability of tilapia mechanically separated meat during frozen storage. It was found that antioxidants could reduce oxidation reactions, while green tea and propolis extracts did not significantly delay lipid oxidation.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
