• Resumen

  • Over the past years, global production of fish from aquaculture has grown rapidly, contributing to significant quantities to the world’s supply of fish for human consumption. Unfortunately, the sustainable expansion of this sector is currently hampered by a number of factors constraining fish production and development in terms of quantity and quality. Amongst those factors we find the intensification which leads to overcrowding and the decrease of water quality, facilitating the spread of pathogens and increasing disease outbreaks such as oxidative stress and infectious diseases causing high mortalities within diverse fish species. To control the emergence of pathogens in aquaculture, antimicrobial agents are employed, but their overuse has lead to the spread of resistant bacteria that puts a huge pressure on aquatic animal’s health as well as consumers. Thus, in this work we aim to extract Origanum compactum essential oil. Then, study its antibacterial and antioxidant activities against two fish pathogens and evaluate their capacity to substitute antimicrobials for a further in vivo investigation in aquaculture as dietary supplements to further increase fish immunity, hematological responses and growth performance.
