Problem Statement:

Develop a concept to improve the methods for fish waste removal in an average raceway (hatchery). Also, to develop a test apparatus that will simulate and test current methods as well as our improved conceptual method for waste removal. It must be easily to manufacture with minimal tools and skills.

Some of the needs and wants of the customer:

Maintenance:

  • Maintenance Free (2-5 years).
  • Has ability to be backflushed.
  • Write up a likely maintenance schedule.
  • Consideration of down time when pulling maintenace.

    Functional performance:

  • Effectively takes waste off bottom of raceway.
  • Low fish mortality rate.
  • Minimize height to maximize volume to raise fish.

    Spatial constraints:

  • Must fit in bottom of virtually any raceway.
  • Tentative max height: 1 ft.
  • Must be retro-fit into existing raceway.
  • Adjustability in respect with retro-fit.

    Manufacturing:

  • Easy to fabricate with minimal tools.
  • Built in sections to be easily installed/transported if necessary.

    Appearance:

  • Should look clean, professional, and finishes like a snug-fit.

    Cost:

  • $1500/less to design and build initial prototype.
  • Tentatively $500-1000 to build finished product for average raceway of 100’ X 10’.

    Time:

  • Needs to cycle around 24 hours.
  • Consideration of water conservation (short cycle).
  • Must have a reasonable lifetime (w.r.t. cost).
  • Consideration of downtime.
