It is considered that most infections caused by pathogen agents in fish species raised in the closed medium like fishing farms originate from the natural environment, thus there are few information on virus transmission from species raised in aquaculture programs to the wild ones. This issue is important taking into account that the wild sturgeon populations are critically endangerment, and regarding to the IUCN Red List, two of these are already declared extinct. Within Danube Basin, environmental and anthropic factors series (reproduction habitats lost, hydrotechnical works) have caused the sturgeon distribution area to be restricted mainly in the lower segment of the river. In addition, intensive fishing or the introduction of invasive species have produced negative effects and hence the decrease in the population effectiveness. As result, from six native sturgeon species within Danube Basin, in our days, only four are still found. This review shall include an analysis of the status of knowledge, regarding the possible influence which the transmission of some viruses within sNCLDV from aquaculture species to the wild ones, also it shall propose an assessment of the risk of infection within Danube ichthyofaunal.

Shortnose sturgeon are listed as a species of special concern in Canada and as endangered in the US. Increasing knowledge about this species, particularly in the area of reproductive biology, will better the management of wild populations and aid in the development of assisted reproduction protocols. However, access to wild sperm is limited, so short-term and long-term storage of sperm from sturgeon is crucial for reproductive studies. Here we report on testing and development of a short-term storage protocol for shortnose sturgeon. Milt samples were collected from wild shortnose sturgeon caught in the Wolastoq River. Subsets of semen were mixed with different extenders with or without oxygen; control treatments without extenders were also run. We used computer-assisted sperm analysis (CASA) to determine sperm motility and swimming kinematics for the different treatments. All groups were examined immediately after collection and treatment application, and then 1, 2, and 7 days after storage in a fridge (4°C) for experiment 1, and days 1, 3, 7, 10, 14, 17, 21, and 24 for experiment 2. The response variables motility, curvilinear velocity (VCL), linearity (LIN), and wobble (WOB) showed an overall decrease over time with differences between extender treatments. While untreated milt maintained some motility up to day 21, the addition of an extender reduced decline in motility and improved longevity up to day 24. Milt treated with the Park and Chapman extender had the slowest motility decline of extenders used, and milt treated with the modified Tsvetkova extender showed less potential for contamination.
