Introduction to In-Pond Raceway Systems
(IPRS)
 IPRS integrates fish in a portion
of the pond with flowing water
system.
 circulate and mix pond water to
optimize fish growth while
preventing environmental
discharge.
In-Pond Raceway System – The Theory and
History
 IPRS started in the late 1980s in the US at
Auburn, Clemson & Mississippi State
University, led by Drs. David Brune, Mike
Masser & Andy Lazur
 With support from the ACES and USSEC
research refined IPRS leading to the creation
of WWUs.
 Since its introduction, IPRS has spread to over
18 countries including Tanzania (TANLAPIA)

 Adequate and reliable
water supply
 Sufficient land area
 Topography and Climate
considerations
Site selection for in pond race way
 Access to essential utilities
such as electricity
 regulatory requirements and
permits
 Proximity to markets and
distribution channels
Components of in pond race way
 Whitewater Units (WWU)
create a vertical and horizontal water
flow
 Raceway Cells
5m x 2.3m x 30m, have mesh ends.
Cells divided into CZ, PZ, and QZ
segments.
 Supplementary Aeration (SA)
Supplementary aeration enhances
fish health and waste treatment.
Cont..
 Working Walkways (WW)
1.8-2m supports feeding&
maintenance. made of steel,
fiberglass, concrete/wood.
 Confinement Gates (CG)&Gate
slots
located at both ends of the PZ,
serve to retain fish and optimize
water exchange.
The Baffle Wall (BW)
It guides water from the IPRS cells &
WWUs. Allow mixing and aeration.
made of earthen material/UV-
protected HDPE
Cont..
 Electrical and Back-up Power
Systems
 Spare Equipment and Backup
Systems
 Waste Management and Extraction
Submerged vacuum head drawn across QZ floor by
cable & Vacuum system on rail structure travels along
QZ length.
 Filter-feeding or Service Species
Culture Techniques, Operation and
Maintenance of IPRS
 Stocking density
It base on biomass, harvest size,
volume; ranges 100-150 kg/m3.
involves healthy, uniform
"stockers,“(20-25g)
 Management of Filter feeding
and Service Species
The "80:20" principle developed
USSEC
Feeds and Feeding
Hand-feed fish to
satisfaction.
Feed Storage
first-in, first-out
Cont..
 Water and Water Quality
Management
No water exchange, as the aerated
system ensures stability, with minimal
fluctuations in D.O, pH, and NH3
 Confinement Gates management
Clean and debris-free gates with
properly sized mesh ensure robust
water movement while retaining fish
 Floating Waste Solids
fish species e.g. tilapia, floating fecal
matter pose challenges Adjusting feed
formulations can mitigate this issue
 Fish Health Management in
Raceways
stocking healthy fingerlings, quality
feed, water quality and liming
Cont..
Harvesting from In-Pond Raceways
 IPRS facilitates stress-free,
cost-effective fish harvests.
 No need for seining
equipment; fish are harvested
at target size, minimizing stress.
Record Keeping and IPRS Performance
Monitoring
 Detailed records should
be maintained to track
various parameters such
as water quality, fish
health, feeding regimes,
and maintenance activities
Maintenance of In-Pond Raceway Systems
 Timely maintenance, including filter
cleaning and diffuser inspection, prevent
issues like clogging or malfunctioning.
 Backup generators must be checked and
tested weekly
 The baffle should be inspected on a
monthly schedule for rips, holes or
deterioration.
Economics of IPRS
Investment and Construction Costs
 Land acquisition/rental, pond
construction, water & electrical
systems installation
 machinery & equipment such as
feed storage bins, buildings,
feeding equipment, water
chemistry kits, WWUs, harvesting
gear &vehicles.
Variable Costs
 expenditures for fingerlings, feed,
labor, electricity, chemicals, and
other items necessary for fish
production.
 Feed costs 40%-75% fingerlings
9% -49%, electricity 4%-6%)&
management/labor 3%-13%
Cont..
Fixed Costs Fixed
 costs are those that an operation incurs
whether fish are produced or not
 land, pond construction, equipment,
machinery, repairs, maintenance, taxes and
insurance.
Revenue
 come from selling the fish quantity raised
and harvested at one or more price points
 Tanzania farm gate price 7000/=/kg of
tilapia fish
Marketing
 wholesalers, middlemen, retailers,
and individuals
 Advertisement
How IPRS differ from other aquaculture
farming methods
Advantage of IPRS
 Enhanced Environmental Sustainability
 Increased Production Yield
