• Target: It’s a treatment for sea lice (like Lepeophtheirus salmonis) on farmed salmon.
• Application: It’s mixed into feed pellets (10 mg/kg/day for 7 days) and eaten by the fish.
• Efficacy: It’s effective against young lice (chalimus and preadult stages) and reduces overall infestation.
• Parasite Stages: Calicide is effective only against the developing (moulting) larval and pre-adult stages of the sea lice.
• Treatment Strategy: If adult lice are present, a separate appropriate “adulticide” treatment is recommended prior to using Calicide to ensure comprehensive control of the infestation.

ADMINISTRATION

• Treatment Duration: Treatment typically lasts for a specific number of consecutive days.
• Mixing and Preparation: The product is a powder premix that is intended to be incorporated into commercial fish feed pellets. This is often achieved by coating the pellets with the powder, frequently using fish oil to help the medication adhere properly. This mixing process is typically conducted in an approved feed mill.
• Feeding:
  • It is important that all fish consume a sufficient quantity of medicated feed for the treatment to be effective.
  • The necessary amount is often included in a portion of the daily feed ration and given as the initial feed of the day.
  • Any additional feeding can be provided using unmedicated feed.
  • The intake of medicated feed can be influenced by the clinical condition of the animals, such as their appetite. Therefore, accurate dosing may need to consider actual feed consumption.
