Full Description

"Oyster toadfish choruses occurred on both sides of the high tide but were present in similar amounts from _60° to 60° tidal phase (Fig. 8)."

"Persistent toadfish choruses were not observed in Deployment I and were most numerous during Deployment II, peaking in mid-July (Fig. 9). Toadfish chorusing was present at all times of day, though there were fewer occurrences during the mid-day hours (10:00_ 14:00 h) than in evening and early morning hours (21:00 to 06:00 h) (Fig. 10)."

Observation Environment Quotes

"Passive recorders were deployed at 8 sites, within a mixture of seagrass, saltmarsh, oyster reef and soft-bottom habitats, and sampled for 2 min every 20 min between June and August 2014."

Full Description

"The high-frequency band was selected to exclude energy associated with perch chorusing frequencies (which extend up to ~5 kHz), and to include energy in frequencies associated with snapping shrimp (Au & Banks 1998), also a major contributor of acoustic energy to estuarine soundscapes (Lillis et al. 2014, Bohnenstiehl et al. 2016)."

"Silver perch choruses occurred during falling high tides (0_100° tidal phase), with the most choruses present at 20° to 40° tidal phase (Fig. 8)."

"Silver perch were most prominent in Deployment I, with choruses dying off by mid-August (Fig. 9). The perch choruses may also have been influenced by lunar phase, as fewer choruses were present between the full and new moon phases but would increase in duration and abundance around the new and full moon (Fig. 9). Perch choruses occurred at night, after sunset, through the early morning hours, and were not present during daytime recordings (Fig. 10)."

"Though sound production by silver perch is associated with spawning and not feeding, previous studies illustrate that perch use and move into flooded habitats during nighttime and high tide, suggesting that they may do the same when spawning. A previous study found that both maximum daily sound production, as well as appearance of eggs and larvae for the silver perch, occurred between 17:00 and 22:00 h, further supporting the fact that silver perch are active at night in these estuarine habitats (Mok & Gilmore 1983)."

"Soniferous fish, such as silver perch, produce sounds associated with spawning to attract mates (Mok & Gilmore 1983)."
