Shellfish, like any farmed livestock, may harbor disease-causing pathogens that are harmful to shellfish health and, potentially, human health. Sometimes, disease-causing pathogens, like species of Vibrio and Aeromonas bacteria, directly affect health outcomes. Water used for larval shellfish hatcheries is typically treated by filtration, UV, or ozone which have varying levels of success at consistently reducing bacteria. One concern with these treatment systems is that they may leave organic material behind in the water while also failing to kill all bacteria, leading to increased growth of potentially pathogenic bacteria on the organic material left behind. Outside of the United States, shellfish can also be treated with antibiotics in order to manage these harmful bacteria. Studies have shown that use of these antibiotics has been linked to the development of resistant bacterial strains. Probiotics provide a more environmentally friendly alternative to manage disease risks to successfully rear larvae in ...
