The Effects Of Diatom-Specific Polyunsaturated Aldehydes On Larval Zebrafish (Danio Rerio), Rachel Raymer
WWU Graduate School Collection
Diatoms are ubiquitous in marine planktonic and benthic environments and are common in diets for many lower-trophic organisms. Certain species of diatoms produce polyunsaturated aldehydes (PUAs) that can exist in particulate and dissolved forms. Diatom PUAs are known for negatively affecting the fecundity of their primary consumers, including invertebrate grazers like copepods and echinoderms. However, little is known about the effects of diatom PUAs on vertebrates that may be exposed to dissolved or ingested PUAs due to overlapping distribution with diatom populations. The purpose of this study was to test whether dissolved diatom PUAs affect the early life stages of …

This research provides insight on the effects that polyunsaturated aldehydes (PUAs) have on model species zebrafish heart rate and mortality. Zebrafish were used as an analog for forage fish, which are of both ecological and economic importance. Forage fish often interact with diatoms, some species of which have been known to emit allelopathic chemicals, PUAs. These chemicals can have a deleterious effect on invertebrates that cohabitate with or consume diatoms, but their effects on vertebrates was unknown. In the lab, zebrafish eggs were exposed to three different concentrations of PUAs plus two controls and observed to determine any effects on …
