Ammonia exposure can be considered more stressful for aquatic animals when it coincides with high temperature. This study was conducted to detect the effects of ammonia and heat stress their interactions on histological features gills liver tissues expression responses immune antioxidative related genes in Nile tilapia. Thus, 180 fish were divided into four groups (triplicates), where first third kept clean water without total ammonium nitrogen (TAN) exposure. At same time, second fourth exposed 5 mg TAN/L. After seven days, temperature raised (without toxicity) (exposed TAN/L) up 32 °C under these conditions 24 h. While optimum (27.28 °C) then dissected. Marked upregulation keap1 seen ammonia/heat stress.

The aquaculture sector is one of the main activities contributing to food security for humanity around globe. However, aquatic animals are susceptible several farming stressors involved in deteriorated growth performance, reduced productivity, and eventually high mortality rates. In some countries still, antibiotics chemotherapies comprehensively applied control biotic stressors. Aside from apparent benefits, continuous usage develops bacterial resistance, deteriorates populations, accumulates these compounds environment. Alternatively, environmentally friendly additives were used avoid direct indirect impacts on ecosystem human health. aquaculture, medicinal herbs extracts extensively approved their growth-promoting, anti-inflammatory, antioxidative properties. Herbal essential oils contain many bioactive components with powerful antibacterial, antioxidative, immunostimulant potentials, suggesting application animals. Essential can be provided via diet benefit by improving well-being health status. use aquafeed has been studied a variety determine beneficial roles optimum doses. outputs illustrated that herbal exciting alternatives prominent promotion, roles. Herein, we reviewed aquaculture. This review also aims describe trends use, mainly commercial fish species, analyze different factors affect oils' efficacy immune responses finfish species.

Fish are among the best-studied aquatic animals due to their economic and ecological values. meat is most affordable protein source for economically weaker section of people. The environment almost all ecosystems has a specific influential role on or by fishes. Therefore, studying stress biology, especially oxidative stress, vital because it can influence growth, production, reproduction, etc. To review above topic, peer-reviewed electronic databases, including Web Science, science direct, PubMed, Google Scholar, Scopus, AGRICOLA, were searched with keywords associated fish, diseases, abiotic such as effects water dissolved oxygen, temperature, salinity, hardness, alkalinity, pH, pollutants, heavy metals, anthropogenic activities, was reviewed in current article draw conclusion updated relation that exists between fish physiology, disease, stressors. Oxidative redox regulatory levels under parameters anti-stress responses differ various models. Undoubtedly, factors modulate health status greater extent, therefore, these must be considered priority basis improve general immunity fish. statement remains valid both saline freshwater habitats.

Sustainable development of the largemouth bass industry is hindered by limited freshwater resources. Consequently, expansion farming space brackish and saline water aquaculture has become imperative. Largemouth an economically important fish species. However, there presently a lack germplasm resources with capacity to adapt hypertonic environments maintain rapid growth. A genome-wide association study technique used for detection genetic variants associated specific phenotypic traits. In this study, we firstly applied explore potential single-nucleotide polymorphism (SNP) locus candidate genes growth adaptation environment bass. total 10 growth-related SNPs were obtained on chromosome 16, SNP16:4120214 was significant SNP peak. Based these SNPs, 23 annotated in genome, including Nkcc1, Mapkap1, Hmgcs1, Slc27a6, Shroom3.

Balanced aquafeed is the key factor for enhancing productivity of aquatic animals. In this context, animals require optimal amounts lipids, proteins, carbohydrates, vitamins, and minerals. The original plant animals’ ingredients in basal diets are insufficient to provide with suitable Concurrently, elements should be incorporated doses, which differ based on diets’ species, age, size, composition. Selenium one essential trace involved various metabolic, biological, physiological functions. Se acts as a precursor antioxidative enzyme synthesis leading high total capacity. Further, can enhance immune response tolerance infectious diseases. Several metabolic mechanisms, such thyroid hormone production, cytokine formation, fecundity, DNA synthesis, sufficient addition. recent progress nanotechnology industry also applied production nanoparticles.

Abstract African catfish is a freshwater species with high ability to resist brackish water conditions, but heat stress may impair the health status of fish. Thus, impact varying levels salinity (0, 4, 8, and 12 ppt) was investigated on growth performance, survival rate, blood biochemistry (average weight: 180.58 ± 2.8 g average length: 38 1.2 cm) for 4 weeks; then, fish were stressed temperature (32 °C) 72 h. The performance rate markedly higher in reared 0, 8 ppt than ( p < 0.05).
