ISA spread through red blood cells according to new research. In her doctoral thesis, Maria Aamelfot studied the how the interaction between Atlantic salmon and
the ISA virus leads to the development and spread of ISA in fish.
Aamelfot focused to finding out what type of cells are
receptive to the virus and what type of cells become
infected by the virus. Her findings describe the ability of the virus to
infect or damage certain cells, tissues or organs.
The Bureau of Fisheries and Aquatic Resources Region 2 (BFAR-2), The Philippines is
proposing a new technique in fish cage operations based on the result of
the harvest field day demo and research project at the Magat Reservoir.
Information Officer Max Prudencio said that the demo and research
project, which showcased the viability of fish cages in the Magat
Aquapark, aims is to revitalize the once-vibrant aquaculture industry in
said area.
A cooperative report between the salmon industry, environmental groups and academic institutions in British Columbia has identified the
optimum time to treat for sea lice to protect wild
fish migrating at the north end of Vancouver Island.
The paper, published this month in PLOS One, identifyied the
optimum time to treat for sea lice to protect wild
fish migrating at the north end of Vancouver Island.
Researchers developed a mathematical model for the population dynamics of parasitic
sea lice (Lepeophtheirus salmonis) on domesticated populations of Atlantic salmon (Salmo salar)
in the Broughton Archipelago region of British Columbia. The model was
fit to a seven-year dataset of monthly sea louse counts on farms in the
area to estimate population growth rates in relation to abiotic factors
(temperature and salinity), local host density (measured as cohort
surface area), and the use of a parasiticide, emamectin benzoate, on
farms.
