Electroreception and Communication in Fishes

  • 1 November 1996
This concise review focuses on recent advances in the function and mechanism of electroreceptive systems in lower aquatic vertebrates and elucidates the sophisticated principles of communication,
Intraspecific variability of the pulse-type discharges of the African electric fishes, Pollimyrus isidori and Petrocephalus bovei (Mormyridae, Teleostei), and their dependence on water conductivity.
TLDR
The occurrence of multiple discharges per primary neural command signal at very low conductivities, indicates that P. isidori is adapted to conductivities above 17 microS/cm, and P. bovei to those above 5 microS/, and need not be the result of intraspecific selection.
Electric organ discharge interaction during interspecific agonistic behaviour in freely swimming mormyrid fish

  • 1 September 1974
SummaryA data acquisition technique is described, which uses a digital analyser to measure off-line the lengths of intervals between events on two (or more) lines. The method compensates for
The Sexually Dimorphic Jamming Avoidance Response in the Electric Fish Eigenmannia (Teleostei, Gymnotiformes)
TLDR
None of the 14 fish showed a frequency difference vs response curve close to optimal for the purpose of jamming avoidance, and the JAR showed strong habituation.
A morphological study on species of African Mormyrus (Teleostei: Mormyridae) and their electric organ discharges
Five species of Mormyrus Linné 1758, three from West Africa and one each from East and southern Africa, were compared morphologically, and their electric organ discharges (EODs) recorded in the
No sex difference in the waveform of the pulse type electric fish,Gnathonemus petersii (Mormyridae)
TLDR
Gnathonemus petersii very likely relies on mechanisms other than discrimination of intraspecific EOD waveforms for mate recognition, and in none of four quantitative EODWaveform measures can a sexual dimorphism be discerned.
Electrosensory prey detection in the African sharptooth catfish, Clarias gariepinus (Clariidae), of a weakly electric mormyrid fish, the bulldog (Marcusenius macrolepidotus)

  • 24 August 2000
TLDR
The results suggest that sharptooth catfish rely heavily on their acute electrical sense during hunting, and an important function for electroreception in an African catfish has been identified.
Electrocommunication in Teleost Fishes: Behavior and Experiments
  • B. Kramer
  • Biology, Environmental Science
  • 18 October 1990
TLDR
This volume provides a detailed account of bony fishes' biology and behavior and their sophisticated sensory capacities as well as the physiology and anatomy of the electrosensory-motor system and the integration to form an efficient intelligence system.
