The SpiroFri project seeks to gain increased knowledge about the Spironucleus salmonicida fish parasite to prevent infection. 

The microbiome of a parasite – meaning everything that lives inside the parasites – can play a role in salmon health, a new study says. 

The Canadian government is providing $2 million to help revitalize the Cape Breton oyster farming industry destroyed by MSX parasite. 

Study says floating cages could help revitalize the Cape Breton oyster farming industry destroyed by MSX parasite 20 years earlier. 

Cawthron Institute has developed “BeNeZe” – a new web tool to help fish farmers manage parasitic infection in Kingfish and Amberjacks 

This article presents the results of a study using environmental DNA methodology for the early detection and quantification of various pathogens in farmed barramundi, where the technique showed to be a powerful and novel tool to predict fish mortalities. 

The preventive use of common salt (sodium chloride) by commercial producers of freshwater fishes has many benefits, including helping with the routine prevention of losses due to diseases, stress and mishandling during transport, harvesting, grading, counting, weighing and induced spawning. 

Quantification of fish behavior is complex and depends on the experimental setup and biomarkers applied. A simple method was tested to quantify locomotor behavior to evaluate the effects of simulated water treatment scenarios using peracetic acid. 

The authors conducted a study to evaluate whether treatment of Trichodina-parasitized tilapia with formalin would improve fish survival and reduce F. columnare infection. Tilapia not treated with formalin showed significantly higher mortality than treated fish. 

Obligate and opportunistic parasites play a critical role in determining the productivity, sustainability and economic viability of global finfish aquaculture enterprises. Without stringent and appropriate control measures, the impacts of these pathogens can often be significant.
