|Abstract||The Pacific blue shrimp Litopenaeus stylirostris was introduced in New Caledonia thirty years ago. Because of its high inbreeding, a SPF strain domesticated in Hawaii, genetically differentiated from the Caledonian strain, had to be imported. The two strains’ reproductive performances were compared at different periods and cross breedings were assessed. The average results show that Caledonian animals give twice as many nauplii than the Hawaiian animals. The best cross breeding is obtained with Caledonian male x Hawaiian female. A possible explanation is the later age or weight of maturity for the Hawaiian strain compared to the Caledonian strain, difference which could come from the geographical origins and/or the zootechnical and climatic domestication conditions.|
