Presentation Transcript

  1. Applied Research at Lethbridge Community College (an emphasis on Aquaculture) By: John Derksen

  2. Introduction • The LCC research philosophy. • Aquaculture research at LCC • past, present and future. • organizational framework. • funding, and driving forces.

  3. LCC Research Philosophy • Emphasis - applied research v.s. pure. • Research is curriculum driven. • Focus on increasing student skills, experience and practical knowledge. • STUDENT INSTRUCTOR RESEARCH

  4. Aquaculture Research • Past Present • Cooperative Aquaculture Research Project (CARP) • A 5 year cooperative study to explore the viability of... • “Eliminating Aquatic Weeds in Irrigation Canals using Triploid Grass Carp”

  5. Grass Carp Project • Native to Eastern Asia. • Can reach 1m in length and weigh 45 kg. • Can consume 20-30% body weight per day.

  6. Over 8000 km of canal in Alberta. Vegetation can reduce flow by as much as 80% by August. Need for Vegetation Control

  7. Farm dugouts, also areas of concern. Northern Water Milfoil – a common aquatic plant in Alberta. Vegetation Control

  8. Carp Project (participants) • Initiated by Alberta Agriculture. • Committee formed to oversee all research. • Research and development by: • Alberta Forestry, Lands and Wildlife • Alberta Environment • Agriculture Canada • Alberta Irrigation Projects Assoc. • LCC and University of Lethbridge

  9. Funding • Initially - Irrigation Council of Alberta & Alberta Agriculture. • Later - LCC + Alberta Agriculture + Eastern Irrigation District (EID).

  10. Feasibility Studies • Research concentrated on: • Grass carp requirements • Winter & summer survival in dugouts. • Fish survival in flowing systems (canals). • Effectiveness of fish to control aquatic plants. • Preference of aquatic plant by fish.

  11. LCC’s involvement • Applied for acknowledgement as an Applied Research Site. • Together with EID, LCC constructed a recirculating aquaculture facility on campus to spawn and raise grass carp.

  12. Virtual Tour of Campus Facility

  13. LCC’s Grass Carp Hatchery

  14. The Inner Workings

  15. Early rearing • Larval grow out tanks • Early rearing fry tanks

  16. Birds’ eye view of fish

  17. Advanced Technology

  18. Certified Triploid All triploid Grass Carp are verified and tagged before they leave the building.

  19. Expansion of Research

  20. Silver Carp Hypopthalmichthys molitrix

  21. Aquaculture Centre of Excellence

  22. Aquaculture Centre of Excellence • Research Programs • Eagle Lake Strain Rainbow trout (2000-2002) • Aquaponics – fish waste nutrient transfer (2000-2002) • Aquaculture Engineering – ozone applications (1999-2000) • Aquaculture Wastes – effluent management (2000-2002)

  23. Summation • Curriculum drives the research. • Partnerships have: • - transferred technology • - enhanced provincial aquaculture • - provided environmental solutions

  24. A final thought! “Research is a perpetual loop, for every question answered two or more questions arise.”
