Fish swimming behavior is a commonly measured response in aquatic
ecotoxicology because behavior is considered a whole organism-level effect
that integrates many sensory systems. Recent advancements in animal
behavior models, such as hidden Markov chain models (HMM), suggest an
improved analytical approach for toxicology. Using both new and
traditional approaches, we examined the sublethal effects of PCB126 and
methylmercury on yellow perch (YP) larvae (Perca flavescens) using three
doses. Both approaches indicate larvae increase activity after exposure to
either chemical. The middle methylmercury-dosed larvae showed multiple
altered behavior patterns. First, larvae had a general increase in
activity, typically performing more behavior states, more time swimming,
and more swimming bouts per second. Second, when larvae were in a slow or
medium swimming state, these larvae tended to switch between these states
more often. Third, larvae swam slower during the swimming bouts. The upper
PCB126-dosed larvae exhibited a higher proportion and a fast swimming
state, but the total time spent swimming fast decreased. The middle
PCB126-dosed larvae transitioned from fast to slow swimming states less
often than the control larvae. These results indicate that developmental
exposure to very low doses of these neurotoxicants alters YP larvae
overall swimming behaviors, suggesting neurodevelopment alteration.
As described in the journal article, this data was generated by Ctrax
tracking software using videos of fish free swimming in petri dishes. All
tracking errors have been corrected in this data and distance and turning
angles have been calculated using the movement criteria stated in the
manuscript. This data is the data used to conduct the Hidden Markov Chain
models and calculate average individual fish behavior endpoints.
