“…Cotton core electrodes (Northmore and Muntz, 1970;Matsuda and Wilder, 2010) and metal electrodes (Horodysky et al, 2013;Kopperud and Grace, 2017;Warrington et al, 2017;Kingston et al, 2019) can also be used. After the 1960s, glass microelectrodes began to be used in numerous applications (Karita et al, 1973;Clark, 1975;Mccormick et al, 2019;Venkatraman et al, 2020;…”

“…Other kinds of electrodes, such as stainless steel electrodes (Fuentespardo et al, 1997) and polyethylene pipe steel electrodes (Weber, 1982), are less commonly used. To date, tungsten halogen lamps (Weber, 1982), xenon lamps (Karita et al, 1973;Clark, 1975;King-Smith and Cronin, 1996), and light-emitting diodes (LEDs) (Vetter et al, 2019;Hasenei et al, 2020) are the main light sources used in ERG studies, and the light intensity and wavelength range are controlled by neutral filters and interference filters.…”

The light environments of natural water sources have specific characteristics. For the majority of aquatic organisms, vision is crucial for predation, hiding from predators, communicating information, and reproduction. Electroretinography (ERG) is a diagnostic method used for assessing visual function. An electroretinogram records the comprehensive potential response of retinal cells under light stimuli and divides it into several components. Unique wave components are derived from different retinal cells, thus retinal function can be determined by analyzing these components. This review provides an overview of the milestones of ERG technology, describing how ERG is used to study visual sensitivity (e.g., spectral sensitivity, luminous sensitivity, and temporal resolution) of fish, crustaceans, mollusks, and other aquatic organisms (seals, sea lions, sea turtles, horseshoe crabs, and jellyfish). In addition, it describes the correlations between visual sensitivity and habitat, the variation of visual sensitivity as a function of individual growth, and the diel cycle changes of visual sensitivity. Efforts to identify the visual sensitivity of different aquatic organisms are vital to understanding the environmental plasticity of biological evolution and for directing aquaculture, marine fishery, and ecosystem management.
