TADPOLE SHRIMP IN AN ANTIBIOTIC SOUP: ARE WE CREATING MONSTERS?
To keep up with a growing human population, U.S. farmers have turned to using antibiotic growth promoters to increase the size of livestock raised and decrease microbial growth amongst populations. The current literature states that 70-90% of these antibiotics are unmetabolized and excreted into the environments surrounding farms, including surface waters. It is understood that antibiotics are prevalent in surface waters, however, it is unknown how it affects the aquatic organisms that inhabit them. To investigate the effects of the antibiotics on aquatic invertebrates, generations of tadpole shrimp (Crustacea: Notostraca: Triops), were exposed to varying concentrations of the antibiotic chlortetracycline in 1L microscosms to determine if it affects the shrimp’s survival, size, and lifespan. We have found that chlortetracycline has not affected shrimp size, survival, and lifespan at ecologically relevant concentrations. Factors such as competition have also been taken into account in order to asses the antibiotic’s ecological impact. A concentration in which no shrimp are able to survive is currently being investigated. We hope this information will contribute to the body of knowledge that guides the regulation of antibiotics in livestock.
