(2020) Negative impact on the reproductive potential of blue jack mackerel Trachurus picturatus by Kudoa sp. infection of the ovary.

Diseases of Aquatic Organisms, 141, 47-52. DOI:10.3354/dao03515 (IF2020 1,753; Q2 Veterinary Sciences)
Summary:

Reproduction of Trachurus picturatus off the western Portuguese coast was studied over 1 yr. During histological analyses, the presence of Kudoa sp. was detected in advanced vitellogenic oocytes. Kudoa infections are known to cause economic loss through the induction of post-mortem liquefaction of fish muscles, but ovarian infection as reported in this study will seriously affect the reproductive potential of the species and thus impact fisheries productivity. Only females showed gonad infection which led to total degradation of advanced vitellogenic oocytes. No macroscopic, somatic or condition indices revealed differences between infected and uninfected females, rendering this infection event a concealed suppression of reproduction.
