This is an exciting time to practice fish medicine as the field is growing rapidly, techniques and standards are evolving, and information exchange is easy and fast. Veterinary medicine for public aquariums, pet fish, aquaculture, fisheries, and research are converging as never before, allowing better care across the disciplines. Increased focus on fish welfare and sustainability is helping to refine the care of individuals and populations.

Leigh and I talked for many years about a fish medicine textbook for the busy clinical veterinarian in practice; a book that could serve as a practical reference for those starting out or already active in the field. Companion animal species have textbooks formatted to provide clinically relevant information that is easy to access during a hectic day. Why not something similar for fish vets? Eventually, we moved from talking about it to making it a reality. This is the result.

This text provides practical clinical information to help veterinarians, biologists, technicians, and students manage cases and situations effectively and efficiently. We want to help people quickly understand the information they need to consider when faced with clinical cases. We have tried to cover important topics across disciplines, with a goal of building an integrated fish health program that can be generalized to different situations. While we feel it is applicable across disciplines, we are sure it speaks most to vets working in public display facilities and pet medicine, as that is what we know best.
