Summary
The document outlines health management practices in Atlantic salmon aquaculture at Mowi ASA, Ireland. It details key processes such as the selection and management of the breeding stock, egg fertilization and incubation, health monitoring, vaccination, and biosecurity. Additionally, it addresses common diseases, including salmon rickettsial septicemia, tenacibaculosis, and amoebic gill disease, as well as control strategies such as the use of cleaner fish. Finally, it highlights challenges such as the proximity of farming stations and the need to reduce antibiotic use through vaccination programs.

Summary
The production of turbot in Galicia has become a key industry and a source of employment, highlighting the role of companies such as Stolt Sea Farm. This Master Thesisintroduces the production process of turbot, as well as the organizational structure and facilities that the Quilmas plant has to achieve efficient production. The functions of the welfare department are further developed, focusing on the health control of the farm and the main pathologies affecting it. The tasks of the production department are also described, with special emphasis on food management and population density control.

Summary
This master’s thesis describes the activities carried out during my traineeship at the Lira turbot (Carnota) aquaculture plant, owned by the Stolt Sea Farm. An introduction is included on the current status of aquaculture and the importance of the culture of turbot (Scophthalmus maximus). In addition, the facilities and organization of the farm are described, as well as the main pathologies detected in the plant. The tasks performed in the Welfare and Production departments are detailed, highlighting the importance of health control and efficient management of food to ensure optimal crop development and improve productive results.

Summary
Climate change is predicted to negatively affect mussel (Mytilus galloprovincialis) culture in Galicia. In order to take measures against that impact, it is necessary to understand the molecular mechanisms of the species involved in heat resistance. Heat Shock Proteins (hsp) are a key factor in cellular homeostasis as well as the biological response to thermal stress. However, comparative analyses of HSP gene expression in different conditions of thermal stress have not yet been carried out. This research establishes the bases to carry out such analyses by characterizing HSP genes, establishing the phylogenetic relationships of their gene families and calibrating specific primers for quantitative PCR experiments. Ten genes potentially involved in the response to thermal stress were chosen and sequenced. Their phylogenetic analysis showcased interspecific grouping of the orthologous genes according to gene sub-family rather than to species. Primers for six HSP genes and one housekeeping gene were successfully designed and calibrated. Their standard curves and their efficiencies for qRT-PCR analyses were also established. This study provides a molecular tool to quantify the differential expression of HSP genes in response to in vitro induced thermal stress in M. galloprovincialis.

Summary
Report on external internships in the Avramar company located in the province of Alicante, Valencian Community, during the months of September and January (2024 - 2025). In the company, croaker, sea bream and sea bass species are grown in a total of 48 cages, some 25 meters in diameter and others 38 meters in diameter. Feeding is automated from a platform - silo located within the offshore facility. In this, the feed is loaded into different tanks depending on the type of feed and the size of the pellet. The feed is directed from the office or from the platform itself. Finally, I was lucky enough to participate in all the maneuvers carried out on the farm, such as fishing or planting fingerlings.
