NOFIMA -Remarks and proposals about Latvian
future aquaculture -A demonstration station -Fish
farms combined with spare-time
activities - Duckweed

Eastern Baltic Conference Riga May 2008 2
statements from the conference below
One outsider will ask himself Is this just nice
words or is it genuine expressions for a
prosperous fish farming in Latvia?

3
Fish farming in Latvia to day
  • A modest production
  • Market production 500 t, mostly carp
  • Carp with low selling prize
  • Latvian Bureaucracy in general
  • Advantage or disadvantage for progress?
  • Farm gate sale
  • -Loosing control of correct statistic.
  • -Reduction of income from taxes
  • Federal authorities responsible for aquaculture
  • -More interest in preservation, like threaten
    species, than progress/innovation for profit when
    farming fish.

4
Opportunities for fish farming in Latvia may
depend on
  • The authorities
  • Arrange administration and work out laws and
    guidelines that is a benefit for fish farmers
  • Arrange administration giving advantage to
    innovation
  • Establish institutions directed at education and
    trainee
  • The fish farmers themselves
  • Get together and work out strategy plans for
    profit from farming. Work together.
  • Establish a fish farmers union, mostly based on
    professional interests. Then as a result the
    relevant authorities will have access to an
    established forum when the authorities arranging
    guidelines, taking decisions and treating with
    fish farming questions. A close cooperation
    between authorities and fish farmers
  • Instead of blaming authorities start dialogued
    for improved collaboration!
  • When the intention is a profitable farming go
    for one or two species and priority on crayfish
    and trout.
  • Extend further processing of high value species.
    Resulting in a higher selling price and the total
    production of fish/crayfish may still be moderate
    as forecasted.

5
Latvian Aquaculture Idea no.1 for the future
  • A demonstration plant or a research station

6
LATVIAN DEMONSTRATION FARM
  • Purpose
  • Trainee for new and old farmers in farming
    methods.
  • Technicians and managers. A demo plant working
    as a site for farmers coming together
  • Students.
  • Practical tests. Trainee period
  • Veterinary facilities.
  • Wet lab.
  • Fish disease diagnosis. Training in fish
    virology techniques
  • Water treatment.
  • Use of equipment as CO2 stripper, aeration
    facilities for ponds
  • Breeding Facilities for selected species
  • Crayfish
  • Start feeding, densities, fertilization,
  • Keeping broodstock, growth tests
  • Access to ponds

7
LATVIAN DEMONSTRATION PLANT
  • Purpose
  • Environmental topics
  • Running and demonstration of facilities for
    cleaning the farm outlet. Environmental control.
  • Practices correct feeding. Feeding the fish
    only, not feeding the water. Environmental
    control.
  • Taking care of threaten species or valuable
    stocks
  • Freezing of sperm
  • Keeping alive populations of threaten species
  • Build up a GenBank
  • In Norway 33 threaten stocks of salmon in
    GenBanks

Latvian Demonstration farm One part of the
station with broodstock and hatchery
  • Income. Financing the management of a station
  • -Start with buying selected broodstock
  • -Build up a Latvian broodstock of trout
  • -Build up a Latvian broodstock of crayfish
  • -Strong veterinary control
  • -Management like a quarantine station
  • -Deliver eggs and fry from controlled
    populations income to the station

Latvian Aquaculture Idea no.2 for the future
  • Combination at one farm site with fish/crayfish
    farming and different activity offer to tourists
    and visitors
  • But first some remarks, from one outsider,
    concerning the situation in Latvia to day and
    some modest hope for the future

12
Latvian Aquaculture Idea no.2 for the future
  • Combination of different activity offers to
    visitors and tourists and combined with fish
    farming
  • This has been practices in Latvia for a long time
  • Enlargement and upgrading of this combination may
    be an proper income in the future. Meaning
    expanding the number of activities to the whole
    family, not only the crazy male fishermen
  • Offering a variation like a product of
    wilderness, beautiful countryside, blue lakes,
    added offer of various activities, a farm with
    different animals, for family members, combined
    with income from selling farmed fish.

DUCKWEED

Duckweed
25
Duckweed ????? / udenslecas
  • Use of duckweed as fish feed is by far the most
    widespread application. Duckweed can be fed fresh
    to fish as the only feed, or in combination with
    other feed components to a polyculture of Chinese
    and Indian carp species

26
Duckweed
  • Results indicate that duckweed meal can be
    produced for approximately 25 EUR per kilo in
    Norway - with only 5 months growth season. The
    production costs will presumably be less than 0,2
    EUR per kilo in Southern Africa, if duckweed can
    be grown all year.

27
DUCKWEED
  • It is actually the most efficient protein
    producer in the world with at least three times
    larger crop than soya, up to 45 protein content

An extensive FAO study from 1998 titled
"DUCKWEED A tiny aquatic
plant with enormous potential for agriculture and
environment" http//www.fao.org/ag/AGAinfo/resou
