Melanosis Project 2022

#Aquabench has started in may of 2022 a project that has as objective to identify factors associated with the presentation of melanosis muscle in salmon farming, and to define measures to reduce its presentation. In this project involved 9 companies that represent approximately 70% of the national production.

The #melanosis muscle, is an injury that affects the three salmonid species farmed in Chile, but with a special intensity to the atlantic salmon. Is variable at 3 growing regions of southern Chile (X, XI and XII regions), reaching a high incidence (in some cases up to 40%) in some centers of culture, generating a high economic impact for companies, because of losses due to degradation of the product, removal of the affected portion, and an increase of the process time.

In relation to the variables of risk, is considered as a presentation box multifactorial, where it is likely to be associated with different risk factors (trauma, handling, diet, infectious diseases, etc), which can have an impact on the presentation of different types of melanosis observed. Even when the inflammatory process has been addressed by various groups of researchers, both in Chile and in other producing countries, has not yet been generated sufficient evidence to identify the factors of risk and/or protective specific in the presentation of each pattern of melanosis muscle.

Our company proposed an approach to the problem similar to the one used in projects #Caligus and SRS, which is based on the generation of knowledge from a collaborative and continuous between the producers, focused on the lifting of standardized information for each company with the objective to characterize the clinical picture, assess the factors associated through epidemiological studies and coordinate the development activities of R & D experts in the area.
