How should a dead fish be disposed of legally in France?

Before disposing of a dead fish, decide whether it could support diagnosis. For unusual mortality, place it individually in a labelled leakproof package, keep it chilled without freezing unless instructed by the laboratory, and promptly ask the veterinarian or laboratory how it should be submitted.

For a pet fish that will not be tested, contact a veterinarian, animal crematorium or local authority to identify the locally accepted route. Do not flush the body or discard it into a watercourse or the environment. Garden burial is not automatically lawful: health, environmental or municipal rules may prevent it.

In farming or professional activity, dead fish are animal by-products. Collection, temporary storage and treatment fall under EU Regulation 1069/2009 (French summary) and national arrangements. The operator must use the authorised route established for the holding and retain the required collection and traceability records (French summary); a household rule based on the weight of one animal does not replace those duties. For freshwater fish farms subject to declaration under heading 3.2.7.0, the French-language page on the order of 1 April 2008 explains the rules for removing and storing dead fish before collection or destruction.

Wear gloves, prevent cross-contamination and review the precautions for diseases that fish can transmit to people. Clean equipment and record the date, tank or pond, species, number and observed signs.
