Introduction
The module has been devised by VET-AQUA INTERNATIONAL.
This learning module on Fish Health was developed as part of the Student Workshop Initiative 2004 co-ordinated by AquaTT. It is designed to provide a detailed analysis of the current sampling techniques for disease diagnosis focusing on parasitological, histological, bacteriological, blood and virological sampling.
It also outlines the necessary steps for Gram staining and inoculation of an agar plate (streak plate technique) in a clear and concise manner with diagrams and photographs. This learning unit is an essential tool for students to enhance their sampling and laboratory skills.
The author, Dr Hamish Rodger, has devised a series of presentations focusing on Sampling for Disease Diagnosis, Prevention and Disease Control in Finfish Farming, and Biosecurity and Hygiene in Aquaculture. These presentations document the current methods employed in the field.
The module concentrates on five fish health case studies; a Sea Bass and Sea Bream Hatchery in the Mediterranean region, a Carp and Koi Carp farm in Europe, an Atlantic Salmon freshwater cage site in Europe, a Rainbow Trout freshwater tank site in Europe and four (mainly Atlantic Salmon) sites in Norway at harvest-time. The case studies with comprehensive photographs identify the clinical signs, differential diagnosis, and the methods of investigation, the findings, diagnosis and actions relevant for each site. A glossary is also included as a reference to describe scientific terms and abbreviations used throughout this module.
