The presence of an easy accessible source of live food for marine fish larvae in Europe will reduce the dependency of supplies of Artemia. Copepod nauplii are smaller of size and have a higher nutritional value compared to Artemia. Therefore, several salt-water fish species that cannot be reared on Artemia, might be successful aquaculture species, if reared on copepods.
The POCEFF project involved description and practical testing of several production systems for calanoid copepods, including intensified indoor production.
The main objectives of the project were to optimise the technology for breeding and harvesting copepods, to develop preservation technology for copepod eggs and to test the use of copepods for rearing salt-water fish species. This included:
1.Identification of copepod species suitable for use as cultivated live food organisms in marine larviculture (e.g. species that secure high survival and good growth, normal pigmentation and development of the fish larvae).
2.A technological manual on how to induce subitaneous egg production in adult female copepods.
3.Studies on the effects that various preservation techniques may have on hatching rate, viability and nutritional value of eggs and hatched nauplii of copepods species relevant to the aquaculture industry.
4.A report on the effects of different concentrations of various traditionally used disinfectants on the viability and hatching rate of subitaneous eggs of copepod species relevant to the aquaculture industry.
5.A manual on production of juvenile cold water species such as cod (Gadus morhua) and halibut (Hippoglossus hippoglossus) based on feeding the larvae with calanoide copepods.
6.A manual on production of juvenile temperate water species such as turbot (Scophthalmus maximus) and flounder (Platichthys flesus) based on feeding the larvae with calanoide copepods.
7.A manual on production of juvenile warm water species as seabass and seabream with the use of copepods as live food.
The presentation will reveal overall objectives, problems and results.
