Causes include systemic infection, poor water quality, supersaturation (gas bubble disease) and trauma. Fish have an amazing ability to heal, and as long as there are no underlying disease problems, they will frequently recover from a lost eye.

A fish in the wild could never survive without eyes because it couldn’t see predators approaching or find food. In a tank, however, they can live without being able to see.

Unlike what is possible with the human eye, fish are able to regenerate injuries to the retina at the cellular level. They focus on the retina of fish, since — unlike humans — fish are able to completely regenerate all retinal nerve cells upon injury. Special glia cells take on the function of stem cells.

Frog embryos can fully regrow their eyes after injury, debunking a belief that they can’t. Summary: Scientists have found that frog embryos can fully regrow their eyes after injuries, a breakthrough that may lead one day to the ability to orchestrate tissue regeneration in humans.

Unfortunately, axolotls can not regrow their head, because the brain controls the regeneration process through the nervous system. Losing their head, the brain will not be able to communicate with the organs and the regeneration will not happen.

When a fish is deprived of oxygen, food, and sunlight, it’ll lose its coloring very quickly – hence why it often turns white after it dies. The lack of 02 combined with the absence of sunlight and the loss of nutrients will strip the skin of its vibrant hue.

The lasting effects of popeye vary from a full recovery to cloudy, swollen or even a missing eye. Even in the case of a missing eye, the fish can live a full and normal life. If your fish looses his eye be sure to keep your water very clean to avoid any further infection while the socket is healing.

Because popeye is usually caused by negative environmental aquarium factors, fish suffering from popeye will often be stressed or diseased in other ways, as well. While popeye itself isn’t likely to kill a fish, affected fish could die from other problems, such as septicemia and Hexamita infections.

Call it the Olm, call it the Proteus, call it the Human Fish, call it what you will, but what it is without doubt is one of the most unique creatures on the planet. Averaging some 25-30cm in length, this tube-shaped salamander is the only vertebrate in Europe that is exclusively found underground.

That makes the bigmouth buffalo, which is native to North America and capable of reaching nearly 80 pounds, the oldest age-validated freshwater bony fish—a group that comprises roughly 12,000 species. “A fish that lives over 100 years?

What are the best fish to eat for health?

1. Wild-caught salmon. Share on Pinterest Salmon is a good source of vitamin D and calcium.

6. Cod.
7. Sardines.
8. Herring.

The 8 healthiest fish that Zumpano recommends:

• Salmon. The flesh of this oily fish has a characteristic orange to red color.
• Mackerel. Another oily fish, mackerel is a rich source of omega-3 fatty acids, vitamin D, magnesium, and phosphorus.
• Herring.
• Tuna.
• Lake trout.
• Freshwater whitefish.
• Halibut.
• Bass.

It’s simply too hard to replace adult muskie! But in places where they’ve been introduced, you’re actually helping out by keeping them. In this case, as long as you’re aware of the mercury contamination guidelines, eating muskie is perfectly fine. You’ll soon discover that muskie are a fine addition to your table!

it’s a fisherman’s joke. The muskie is known as ‘the fish of ten thousand casts’ because they’re so tough to catch; that is, not very aggressive. They are ambush predators, so extremely unlikely to attack in deep open water.
