Tridge summary

Several breeding centers in Chile have experienced harmful algae outbreaks and death emergencies due to Thalassiosira Pseudonana, although it does not meet the "red tide" standards. As of November 17, 18 aquaculture centers have activated emergency plans, with 7 of them experiencing mass mortality events. So far, 650 tons of dead fish have been removed, and the situation is being closely monitored until the stress plan concludes.

On November 14, local time, Chile’s National Fisheries and Aquaculture Service (Sernapesca) reported that more than a dozen breeding centers in Los Lagos (Region 10) Reloncavi Estuary and Seno de Reloncavi discovered harmful algae outbreaks and large-scale death emergencies. The plan has been started. After scientific investigation, Thalassiosira Pseudonana is the culprit causing algal blooms. This algae does not affect bivalve molluscs and some other fish, so it does not meet the so-called "red tide" standards. Scientific community It is believed that in spring, ideal light and nutritional conditions are favorable conditions for algae blooms. There is currently no direct evidence that this algal bloom is related to the El Niño phenomenon in South America. Sernapesca reported that as of November 17, 18 aquaculture centers in Chile had activated emergency plans, and mass mortality events were detected in 7 of them. The total salmon and trout biomass affected by the algal ...
