Comparative visual function in five sciaenid fishes inhabiting Chesapeake Bay

Abstract: SUMMARYMaintaining optimal visual performance is a difficult task in the photodynamic coastal and estuarine waters in which western North Atlantic sciaenid fishes support substantial commercial and recreational fisheries. Unavoidable tradeoffs exist between visual sensitivity and resolution, yet sciaenid visual systems have not been characterized despite strong species-specific ecomorphological and microhabitat differentiation. We therefore used electroretinographic techniques to describe the light sensitiviti… Show more

“…The CFF threshold of fish correlates with their lifestyle (Horodysky et al, 2008) and a high CFF is likely to reflect the need to react to fast events in their habitat, at the cost of reduced performance at low light conditions. Pelagic fish CFF varies from around 25 Hz in species living in deeper water, to 80 Hz in the surface-dwelling yellow-fin tuna or the dolphin fish (Fritsches et al, 2005).…”

“…A visual system viewing a flickering light source has a critical flicker fusion (CFF) threshold, above which the flicker becomes too fast for the system to follow (Fritsches et al, 2005), and the light appears continuous to the animal, and not flashing. The CFF threshold varies between animals, and is often related to lifestyle and illumination level, being fast in rapidly moving organisms in bright light and slow in nocturnal slow-movers (Horodysky et al, 2008;Smolka et al, 2013). It is therefore likely that reduced CFF could impair the capacity to react to fast events such as prey capture and predator avoidance.…”

“…Light intensity and photoperiod drive the activity rhythms of marine organisms, especially highly mobile animals such as fi shes (Horodysky et al 2008). In the wild, animals time their activities to coincide with what for them is the most advantageous phase of the solar day, a concept widely known as biological rhythm (Reebs 2002).…”

“…This likely allows them to get the maximum information about the environment around them, especially about predators and prey, as well as to maintain body orientation and coordination of movements during swimming (Kasumyan 2004). The largest otoliths with a high sulcus : otolith ratio were obtained in scianids, which produce low-frequency sounds during competition for feeding or during the breeding season (Horodysky et al 2008).…”
