Fish Disease Diagnostic Laboratory
Information Required with Fish Submission
In addition to a good representative sample of sick fish (see How to Collect and Prepare Samples), the laboratory staff needs a thorough history of the fish, system, and problem in order to make the best recommendations for treatment and prevention.
Not all diseases are infectious (caused by parasites, bacteria, viruses, or fungi). Many diseases are non-infectious (caused by environmental, nutritional, or genetic problems). Fish usually become sick or die because of a combination of factors, so addressing only one factor (e.g., presence of a parasite) may not solve the current problem or prevent additional problems in the future. Some primary causes of disease, such as poor water quality, may not be recognized if only the fish are examined. The initiating cause of a disease problem may have occurred weeks or even months before fish began showing clinical signs.
Important details such as stocking densities, water quality information, system set up, nutrition, number of sick and/or dying fish, and previous treatment information help to fill in different pieces of the puzzle.
When submitting fish and/or water to the Diagnostic Lab for evaluation, please fill out the Client History Form and submit it with the sample. Please fill out the form completely. The Laboratory cannot provide a diagnosis without a thorough history. Complete a separate form for each batch of fish being submitted. Answer questions only as they pertain to the current problem and the batch of fish being submitted, except as appropriate in the “Previous Problems” section. Please label fish and/or water sample bags with business name, contact name, phone number, fish species, and unit (vat/tank/pond) number or identifier.
As with any veterinary practice, the Tropical Aquaculture Laboratory adheres to a strict policy of client confidentiality.
