“…Considering reported criteria for skin disorders in rainbow trout (Oidtmann et al, 2013) and the findings reported in this study, the skin lesions were consistent with RMS. This is the first report of RMS affecting rainbow trout in a RAS system and the evidence that RMS could affect rainbow trout under 50 g (smallest was as necessary to confirm the RMS status of these fish (Metselaar et al, 2022).…”

“…This is the first report of RMS affecting rainbow trout in a RAS system and the evidence that RMS could affect rainbow trout under 50 g (smallest was 35 g) of weight, developing severe lesions similar to what occurs in market size fish. The manuscript by Oh et al ( 2019 ) describes several cases of the disease in rainbow trout in South Korea, in which macroscopic lesions resembling RMS can be seen in juvenile rainbow trout weighed less than 30 g. The high level of mortality observed by Oh et al ( 2019 ) does not reflect the classic case definition for RMS though and further investigations were suggested as necessary to confirm the RMS status of these fish (Metselaar et al, 2022 ).…”

“…Red mark syndrome (RMS) is a widespread, self-resolving skin disease associated with the presence of a Midichloria-like organism (MLO) (Metselaar et al 2022). The first appearance of a syndrome with clinical signs and histopathological findings consistent with RMS dated back to the late 1960s in the USA (Erickson 1969), and the first described outbreak possibly linked to an individual batch of eggs (Nevada Department of Wildlife 1974).…”

Red mark syndrome (RMS) is a widespread skin disease of rainbow trout (Oncorhynchus mykiss). Its aetiological agent is believed to be a Midichloria-like organism, an intracellular bacteria of the order Rickettsiales. RMS has been reported on several occasions, however, a comprehensive analysis of the epidemiology of this disease and its actual economic impact on the trout aquaculture industry is missing. Through a questionnaire-based survey, we estimated the prevalence of RMS and the implications of this infection on trout farms in Italy in 2020-2021. One hundred and nine farms, representing 64% (around 22,000 tons) of the total national production, were surveyed. In short, the results show that RMS in Italian farms is consistently and persistently present on Italian territory, affecting about 30% of farms. RMS is observed to have similar features to those generally described in the literature. Clinical disease is observed more often in springtime; size-wise, the most commonly affected groups are fish close to market size and fish weighing less than 100g (22% of cases). Most interestingly, the recurrence of clinical signs in the same batch of fish was observed in 64% of cases. Despite its diffusion, the disease is not perceived as a major concern in the national trout sector, mainly due to its intermittent nature, low mortality and spontaneous resolution. The main costs associated with RMS were related to antibiotic treatment and commercial downgrading; however, it was impossible to estimate the impact of these on production costs.
