In vitro Study of the Microsporidian Parasite Loma morhua, Using Cod-derived Cells and Novel Culture Techniques
The cod populations of the Canadian Atlantic were once highly productive, generating enormous annual harvests and attracting fishing fleets from many nations. However, through the late 1980s improved fishing technology, unprecedented capture rates, and poor fishery management brought wild stocks bey...

The cod populations of the Canadian Atlantic were once highly productive, generating enormous annual harvests and attracting fishing fleets from many nations. However, through the late 1980s improved fishing technology, unprecedented capture rates, and poor fishery management brought wild stocks beyond the point of collapse. Dwindling harvests in the early 1990s resulted in cod fishing moratoriums, and an end to the productivity for which the fishery was once renowned. Atlantic cod remains a popular food worldwide and the collapse of cod fisheries has done little to abate market demands. Consequently, the cod is considered a prime candidate for aquaculture production, providing the impetus for commercial-scale farming operations. As aquaculture efforts continue to grow, disease management challenges have become a prominent concern. Many parasites are prevalent on cod farms, including intracellular pathogens such as viruses and microsporidians. Detailed research into diseases affecting farming operations is imperative if commercial-scale cod aquaculture is to develop.
