Article Synopsis
  • The study focuses on the Largemouth Bass, a significant freshwater fish in the U.S., and its vulnerability to the bacterial pathogen Francisella orientalis, which can cause severe disease and mortality.
  • The researchers documented three cases of francisellosis in Largemouth Bass from a public display system in Florida and conducted controlled laboratory tests to assess how susceptible Largemouth Bass fingerlings were to this infection.
  • Diagnostic methods confirmed the presence of F. orientalis in the fish, establishing the first known occurrences of this disease in Largemouth Bass in public exhibits and highlighting the importance of considering this infection in cases of granulomatous disease in the species.

The intensive culture of characid teleosts for ornamental trade is highly dependent on live feed organisms, particularly Artemia nauplii, to provide nutrition through the larval stage. Live feeds have inherent disadvantages relative to prepared microparticulate diets (MDs), specifically availability, labor and cost. In this research, the dependence of larval Paracheirodon innesi on live Artemia was confirmed via a nutritional trial.

Echinoderm mass mortality events shape marine ecosystems by altering the dynamics among major benthic groups. The sea urchin , virtually extirpated in the Caribbean in the early 1980s by an unknown cause, recently experienced another mass mortality beginning in January 2022. We investigated the cause of this mass mortality event through combined molecular biological and veterinary pathologic approaches comparing grossly normal and abnormal animals collected from 23 sites, representing locations that were either affected or unaffected at the time of sampling.
