Toxicity of a veterinary medicinal product (VMP) to the Norwegian Lobster Nephrops norvegicus (Linnaeus, 1758)
The study will use post-larval (stage IV) of the Norwegian Lobster to determine the lethal and sub-lethal effects of exposure to a veterinary medicinal product (VMP) coated on salmon feed pellets. The test will be performed in a flow-through seawater system. Individual lobsters (n=20 per treatment) will be fed known quantities of pellet (3 mm) that have been treated with five concentrations of the chemical in addition to a control and solvent control group, for the first 7 days. Uneaten pellets will be removed the following day and recorded. Daily observations for abnormal appearance or behaviour will be recorded. The length of the exposure will include 2 moults recorded in the control group(s). The expected duration is between 30 to 40 days.
To minimise stress, animals will be held in separate chambers for the test, since high rates of cannibalism are expected. The number of lobsters per treatment is adapted from the guidelines for mysid shrimps, as there are no available guidelines for Decapoda.

Etterevaluering
Forsøket er betydelig belastende.
Begrunnelse for etterevalueringen
Grunnet manglende tilgang på forsøksdyr (sjøkreps) ble ikke forsøket gjennomført.
