If the radiation levels are high and the fish is almost always near the surface, UV radiation can cause damage to the skin, leading to infection due to oportunistic bacteria present in water. In nature, this may not happen as UV radiation is reflected to the sky in the hours of maximum radiation (it hits the surface vertically and water acts like a mirror) and fishes do not approach the surface in full daylight (as they protect themselves of being sen by predators). So, in laboratory conditions you can kill fish with UV radiation, but in Nature this would not be so.
A different scenario is worth mentioning for eggs and larvae of fish, these are found in masses near the surface and they lack of protection (pigmented skin) and ability of moving up or down in the water column. This is the case of mayor fisheries species, such as anchovy, herring and sardines and increases in UV radiation can kill a great amount of them. This is the case of all zoplancton, specially in the waters surrounding the South Pole.

What else can I help you with?
How are phytoplankton affected by UV radiation?
Ozone depletion allows the UV rays to come in. These rays kill the planktons.
Can UV light kill fish?
Yes, prolonged exposure to UV light can harm and potentially kill fish by damaging their skin and eyes, disrupting their immune system, and affecting their overall health. UV light can also lead to the growth of harmful algae in fish tanks or ponds, which can further harm the fish.
Does uv rays affect food?
No. Uv (ultraviolet radiation) rays are used on food to kill unwanted bacteria withoud harmful chemicals.
Which are more energetic photons of UV-A radiation or photons of UV-B radiation?
Photons of UV-B radiation are more energetic than photons of UV-A radiation. UV-B radiation has shorter wavelengths and higher energy levels compared to UV-A radiation. UV-B radiation is classified as potentially harmful to human health, while UV-A radiation is less energetic and is more commonly associated with tanning and aging effects on the skin.
Which are more energetic photons of UV A radiation or photons of UV B radiation?
Photons of UV B radiation are more energetic than photons of UV A radiation. UV B radiation has a shorter wavelength and higher energy compared to UV A radiation, making it more damaging to the skin and eyes.
How do uv rays affect your skin?
UV radiation causes skin problems to humans. It can also alter our DNA.
Increased UV radiation causes a type of chain reaction in the oceans?
Increased UV radiation can damage the DNA of phytoplankton and other marine organisms, disrupting their growth and reproduction. This can lead to changes in the food web, impacting higher trophic levels such as fish and marine mammals. Overall, it can alter marine ecosystems and biodiversity.
Which of these is not a reason to avoid UV radiation?
uv radiation destroys vitamin D
Does ozone reflect or absorb UV radiation?
Ozone absorbs UV radiation.
What are five things that kill bacteria outside body?
Heat, UV Radiation, Vinegar, Bleach, Lysol.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.
Which does not belong vitamin D cholesterol UV radiation or keratin?
Hemoglobin
