Title: Warm Water Fish Production as a Niche Market and Diversification Strategy


1
Warm Water Fish Production as a Niche Market and
Diversification Strategy
2
Why aquaculture?
  • Aquaculture in the UK remains a mainly coastal,
    specialised enterprise
  • Not integrated with agriculture
  • Specialised knowledge, sites (water sources),
    markets
  • Off-farm feeds-linked with marine ecosystems

3
Why warm-water fish? Why tilapia?
  • Lack of suitable local species with the right
    qualities
  • Tastes good
  • Feeds low in the food chain
  • Tolerant of culture
  • In many contexts tilapia are raised integrated
    within a broader, terrestrial farming system

4
Warmwater..
  • Maintaining culture systems at the right
    temperature (28oC)
  • Insulated, underutilised farm buildings
  • Low value thermal heat-potential for use locally

5
a rationale diversification approach?
  • Diversification a common aim
  • Many constraints
  • No familiarity with technical and market issues
  • Level of capital required
  • Potential benefits
  • Can be based on locally available feedstock
  • Marketed as local and possibly organic

6
History..and the future
  • Tilapia start-ups in the UK over last two decades
    have been capital intensive
  • Commodity orientation, specialised
  • Now, massive production in the Tropics will make
    commodity market very competitive

7
Scale and function
  • Can tilapia production be simplified to produce
    relatively small amounts of high value fish to
    local and specialised markets?
  • And if so what technical and markets research is
    required?
  • What holistic benefits might result?

8
Technical challenges
  • Naturally tilapias graze on aquatic
    pastures-plankton, bacterial floc
  • Commercial systems tend to feed complete
    feeds-like broiler chickens
  • but they require feed supplementary to natural
    feed to grow well
  • Ok in ponds but..tanks?

9
Trials
10
Clean water or food-rich water?
  • Conventionally waste feed removed by a filter and
    fish raised in clean water
  • Can waste be retained in the system and used as a
    further source of feed?
  • Feeding the fish? Feeding the bacterial floc?
  • Results so far..fish are growing (slower than
    conventional recirculation (filtered) systems.

11
Waste or food???
Natural food rich
Natural food poor
12
But.
  • Water quality remains high without expensive
    filter (25kg/m3 )
  • Lower densities-appropriate,
  • lower risk approach
  • simple design and management of the system
  • Overall yield on 20 crude protein
  • Field beans and barley??

13
Other benefits
  • Without fishmeal/oils and associated problems
  • Only useful effluents-local nutrient reuse
  • Traceability, low fish miles
  • Potentially organic

14
Who will eat the fish?
  • We have identified two major groups
  • Ethnic markets
  • The foodies
  • Small quantities
  • Specialist retailers
  • Farmers markets
  • Internet sales
  • Direct restuarant

15
Ongoing research
  • Trying to understand how to best manage the
    floc system and produce fish profitably
  • Would this meet the needs of rural entrepreneurs?
    What types of farmers might be interested?
  • How could this system contribute to sustainable
    rural livelihoods?
