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

Eastern Baltic Conference Riga May 20082 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?

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.

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.

Latvian AquacultureIdea no.1 for the future

• A demonstration plant or a research station

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 speciesCrayfish

Start feeding, densities, fertilization,Keeping broodstock, growth tests

Access to ponds

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

GenBank

Latvian Demonstration farmOne 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 AquacultureIdea 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

Latvian AquacultureIdea 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.

• Next:Pictures showing examples

Pesque-PagueFish and pay

Creyfish

• Nofima with a new start feed for creyfish

• Results will be open in spring time

• Next picture a king crab

DUCKWEED

Greenhouse and outdoor test culture of duckweed at Kvithamar.

Duckweed

Duckweed ряска / ūdenslēcas

• 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

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.

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"

• Dear friends :Good luck with crayfish in the future

• Thank you
