The regulation of a sea lice medicine, not currently in use on Scottish fish farms, is being consulted on by SEPA, the Scottish Environment Protection Agency.
SEPA is seeking views from interested parties on its proposal to introduce a method for licensing the use of a new sea lice medicine containing the active ingredient deltamethrin.
The deltamethrin product has been sold for a number of years in Norway under the brand name "Alphamax" but is soon to be introduced in the UK for the first time.
SEPA is encouraging anyone with an interest in fish farming and the environment to read its proposal and feed back their support and concerns to the organisation.
Full details of the proposals are available and comments can be made to SEPA by May 19.
