Fish Pathology Archive


Fish Pathology Archive

This section was developed alongside the necropsy manual and designed to give an overview of some lesions attributed to both infectious and non-infectious diseases of the species covered. We have included external and internal images for reference, which are intended as a guide for the pathologist.  Full descriptions and histological detail are available  for  salmonids, but examples from flatfish and gadoids are not widely available. We hope readers will benefit from having these images included as part of the necropsy manual. Please note that the images are subject to Crown Copyright and should not be copied from this web site.
