Fish, like people, are subject to deliberate or accidental exposure to high voltage electrical current. Electrical exposure causing death is referred to as electrocution.
Electric eels can generate an electrical charge of up to 600 volts in order to stun prey and keep predators at bay.
Some fish succumb to pH shock immediately. Others may exhibit symptoms including thrashing, darting, gasping, swimming near the water's surface and trying to jump out of the tank.
electric eel, (genus Electrophorus), any of three species of elongated South American knifefishes that produce powerful electric shocks to stun prey, usually other fish. All three species—the electric eel (Electrophorus electricus), Vari's electric eel (E. varii), and Volta's electric eel (E.
Such species include electric eels, torpedo rays, African freshwater catfish, and elephant-nose fish, all of which send out high-voltage shocks to incapacitate prey.
They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts.
If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress. Talk to your veterinarian about treatment and look into what may be causing the stress and alleviating it.
Fish, like people, are subject to deliberate or accidental exposure to high voltage electrical current. Electrical exposure causing death is referred to as electrocution.
Place the goldfish in a container filled with cool water from his tank. The cool water contains oxygen and will help to revive your fish. Some experts also suggest placing your goldfish right back into the water in his tank, even if he appears dried out.
The electric field does not kill fish but temporarily stuns or impairs those that swim within a 6- to 8-foot radius from the booms. The fish can then be scooped up and handled with little stress or injury.
Electrofishing is a technique used in fisheries science to sample fish populations. Sampling is when biologists study a number of fish from a certain area, measuring and examining them and recording the statistics.
They are actually shocking the water with a strong electrical charge to stun the fish into submission so they can be collected.
Check the fish's eyes.
Look at the eye as a whole. If they're sunken, your fish is dead or near death. Look for cloudy pupils, which is also a sign of death in most aquarium fish. If your fish is a pufferfish, walleye, rabbit fish, or scorpionfish, occasional eye cloudiness might actually be normal.
When water temperatures drop to a point that fish become stunned, it is often fatal. In controlled temperature experiments, fish have recovered after being stunned if they are immediately placed in warmer water.
If you use the back of the hand, the electric shock will cause your muscles to cramp, automatically pulling your hand out of the water. If you use the front of the hand the electricity will make your muscles close & your hand will submerge into the water.
Rather than creating an irregular narrow, ionised path, the charge from the lightning strike spreads out sideways and downwards in an expanding half sphere from the surface. Any fish within a few tens of metres of the same strike point would probably be killed but beyond that they would just feel a tingle.
Although fish and aquarium water can spread germs to people, illness due to keeping fish is rare. By giving routine care to your fish and their aquarium as well as following some simple health tips you are less likely to get sick from touching, feeding, or owning aquarium fish.
The recommended applied voltages to be selected for fishing in low conductivity waters should therefore be 300 - 400 Volts.
In a chronic stress situation, the immune system is weakened, allowing proliferation of parasites and bacteria. Some fish are more sensitive to parasites than others. You may see one fish flash occasionally, but this usually does not indicate an outbreak.
Swim bladder disease is when a fish loses its ability to regulate the air going in and out of its swim bladder. This causes the fish to swim strangely, on its side, or even upside down.
They reduce the danger to themselves by flexing their bodies in a shape that prevents the electric current from passing through their heart. When they are charging up, they stiffen into a line segment very much like a straightedge. This way, the electric current only runs parallel to their tail and behind the heart.
There are no known electric eels outside South America.
Electric Eels
Probably the creature most commonly associated with electricity, the electric eel both uses electricity to sense it's environment and to stun prey.
As previously mentioned, immediately after death, motor neurons maintain some membrane potential, or difference in ion charge, which then starts a domino effect down neural pathways causing movement.
