Study on the prevalence and intensity of three parasites in sturgeon fingerlings cultured in earthen ponds

In 2001, we studied 2600 sturgeon fingerlings including: 2242 Acipenser persicus, 150 Acipenser stellatus, 150 Acipenser nudiventris and 58 Huso huso from Shahid Beheshti and Yousefpour hatcheries for parasitic infection. We found three parasites including Diplostomum spathaceum, Trichodina sp. and Gyrodactylus sp infesting the fish. The prevalence and average intensity of Diplostomum spathaceum was 5.49% and 1.66 for Acipenser persicus, 0.66% and I for Acipenser stellatus and, 22.41% and 5.38, for Huso huso fingerlings respectively. No Diplostomum infection was observed in Acipenser nudiventris. The prevalence and average infection intensity of Trichodina sp. was 45.05% and 76.14 for Acipenser persicus, 44% and 51.36 for Acipenser stellatus, 36% and 63.51 for Acipenser nudiventris, and 32.76% and 34.73 for Huso huso fingerlings, respectively. Totally, the prevalence of Gyrodactylus sp. was 0.46% in the two hatcheries. The prevalence of infection with Gyrodactylus sp. was 0.36% in Acipenser persicus and 2.66% in Acipenser stellatus.
