There is a variety of synthetic and natural antimicrobial compounds used to control the growth of microorganisms. The use of natural antimicrobial agents, due to the low side effects and high antibacterial potential, has captured the attention of scientists. The main aim of this study was to produce polylactic acid-based biodegradable active films containing lemon verbena Essential oil nanoemulsion to control the growth of two common foodborne pathogenic bacteria (Staphylococcus aureus and Escherichia coli) in Rainbow Trout. To aim this, the antibacterial activity (in vitro) of the films were assessed under MIC and MBC assays using the microdilution method. The nanoemulsion was prepared by ultrasonic waves. Based on dynamic light scattering, the mean droplet size was reported at about 22.4 nm. Based on the antibacterial results, the growth of both microorganisms was significantly decreased after 0, 3, and 7 days of storage in comparison with the control group (p <0.05). To sum up, the presence of Lippia citriodora Nanoemulsion in the matrix of the polylactic acid film showed notable antibacterial activity during 7 days of storage at 4˚C (refrigerator). It can be concluded that this film can be a good candidate for food packaging purposes to control the growth of microorganisms.  }, Keywords = {Antimicrobial packaging, Polylactic acid, Lippia citriodora, Nanoemulsion, Rainbow trout, Shelf life}, volume = {8}, Number = {1}, pages = {1-15}, publisher = {Iranian Association of Aquatic Animal Health}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.52547/ijaah.8.1.1}, url = {http://ijaah.ir/article-1-249-en.html}, eprint = {http://ijaah.ir/article-1-249-en.pdf}, journal = {Sustainable Aquaculture and Health Management Journal}, issn = {2821-1383}, eissn = {2821-1383}, year = {2022} } @article{ author = {Rahanandeh, M and Tizkar, babak and Rahanandeh, M}, title = {Research Article: The effects of Datura stramonium L. seed extract on anesthesia of farmed Cyprinus carpio in Guilan province}, abstract ={The anesthetic effect of Datura seed extract was evaluated on 15 pieces of young Cyprinus carpio weighing approximately 25 to 50 g.

Though environmental pollution and the incidence of the disease have always been the significant challenges in the use of aquatic products. Increasing the antibiotic resistance rate in fish pathogens has attracted attention to searching for alternatives to antibiotics. In this regard, nanotechnology as a new and innovative strategy has a range of applications in aquaculture and preserving sea animals and can provide a reliable way to protect farmed fish from pathogens. The producers, therefore, try to eliminate barriers in food fields using nano-based tools and cause growth, proliferation, aquaculture, and water purification to increase production in the aquaculture industry. One of the most outstanding issues that researchers point out nano-scale is finding appropriate methodologies for the synthesis of environment-friendly and non-toxic nanoparticles. The specific chemical, physical and biological properties of nanoparticles have increased the incentive to produce them. Today these agents have found their way into many medical applications, including detection, vaccinations, medicine, and gene transfer. Moreover, the use of nanoparticle-based vaccines for many viral pathogens is a developing field in fish disease research. So, Nanoparticles have been widely taken into consideration as a special and sensitive tool to identify bacterial, fungal and viral diseases in aquaculture.

This can change the pattern of ocean currents and marine productivity to be redistributed, especially to higher latitudes, and reduce the global concentration of phytoplanktons, increasing ocean acidity, creating deoxygenated zones, and inducing episodic shocks to marine systems.
