Federal-State Aquaculture Drug Approval
Partnership Project
  • 38 states, 3 Federal agencies, 8 sponsors,
    private sector involvement
  • 8 years, ended September 2002
  • 12 million
  • 8 drugs (AQUI-S?, chloramine-T, copper sulfate,
    florfenicol, formalin, hydrogen peroxide,
    oxytetracycline (oral immersion), potassium
    permanganate)

OTHER DRUGS UNDER DEVELOPMENT
13
Other Therapeutants Under Development
  • Emamectin benzoate (Slice)sea liceSponsor
    expending time funds to meet CVM requirements
  • Erythromycinbacterial kidney diseasealmost
    complete University of Idahoworking on
    antimicrobial resistance studies in response to
    CVM
  • N-Halamine (MC)columnaris disease,
    Ichthyophthirius, AeromonasNew INAD early
    development stage

14
Other Therapeutants Under Development

  • furunculosis/salmonids enteric
    septicemia/catfishapproved Sponsor
  • Resolved palatability issue
  • Needs no supplemental NADA for Type B medicated
    feed (Romet-TC)
  • Is considering development for other diseases and
    species

16

  • Sponsor met with CVM June 4, 2003
  • SponsorRD Plan in development
  • Efficacy, target animal safety,
  • human food safety studies underway
  • NEED FUNDS FOR RADIOLABELED
  • MATERIAL CONFIRMATORY METHOD
  • Initial approvalall salmonids
