The main objectives are as follows:
* To characterise species, populations and strains of autochtonous Clariidae and Pangasiidae catfish.
* To contribute to the knowledge of their life history.
* To implement monitoring tools that could be used subsequently for the characterisation and monitoring of genetic diversity in cultivated fish stocks (ie. development of DNA microsatellite loci).
* To assess and compare the aquaculture potential of species, populations and hybrids in the Pangasiidae and Clariidae.
* To develop artificial propagation techniques adapted to local conditions in pangasiid species for which captive broodstocks are available.
The work carried out in this project should provide new basic information on the biodiversity and zootechnology of the clariids and pangasiids in the SE Asian region. The precise description and characterisation of species, populations and strains represents an important precondition to the sustainable management of their cultivated and natural stocks and to guide conservation efforts of these economically important resources. It will also contribute to a better knowledge of their phylogenetic and zoogeographic relationships. The evaluation of the aquaculture potential of the autochtonous species (diversification) and the optimisation of their rearing cycle (particularly artificial propagation) through technologies adapted to the local conditions are essential elements for a better production in the future.
The key activities envisaged are:
* Identification and characterisation of species, populations and strains using three complementary disciplines and methods: morphometry, genetics and parasitology (specific Monogenea). The genetic studies will include different techniques adapted to the research goals: Protein electrophoresis, mitochondrial DNA analysis and microsatellite DNA analysis.
* Evaluation and comparison of zootechnical performances (survival, growth, sexual maturation) by means of culture trials carried out in experimental aquaculture stations.
* Identification of environmental requirements of broodfish to attain full sexual maturity under rearing conditions and optimisation of induced breeding, artificial insemination and egg incubation procedures.
* Identification of the natural prey preferentially selected by the larvae and of their feeding requirements; optimisation of larval rearing methods.
