Human urine contains something called nitrates, which can cause increased algae in the water, making it toxic to the fish and other wildlife. "Urine, although sterile, is considered a biohazard and should be discarded appropriately.
Fish pee the same just as you and me. Fish kidneys, usually tucked above their swim bladder, are responsible for filtering out all the bad things in their blood and peeing them out into the water. In fish, some products are actually pushed out through a similar fashion in the gills.
No, you should not pee in lakes and pools. Because they're smaller than oceans, urine can make up a larger percentage of the water in lakes and pools. Business Insider explains that urine can cause algae blooms in lakes, which can poison fish.
No, urinating underwater is unlikely to attract fish or sharks. While it's true that some marine animals are attracted to the scent of urine, the amount of urine that is typically released by a person is not enough to make a significant difference in the water.
Fish pee is full of ammonia, a nitrogen containing compound, and phosphorous, both nutrients that plants crave. These also help feed algae and coral reefs, like a liquid fertilizer that helps keep aquatic ecosystems healthy. Fish are little swimming, urinating, nutrient recycling plants.
Un-ionized ammonia begins causing gill damage at approximately 0.05 mg/L and death at approximately 2.0 mg/L. Keep in mind that most test kits measure total ammonia and not un-ionized ammonia but may make no reference to the difference.
Human Urine: Human urine has been found to have no repellent effects on fish. It seems counter intuitive but if you got a whole bunch of sun screen or bug spay on your line and lures, then peeing on them might actually help you catch more fish.
Repellents: human skin oils, nicotine, bug sprays, sun screens, scented and perfumed soaps, any petroleum distillates like gasoline, marine grease, oil, diesel........ The author of this article is a FISHING CHARTER CAPTAIN on the Treasure Coast of Florida.
Freshwater fish will passively intake water from their environment and then, as their insides are saltier than their surroundings, will excrete a diluted urine. Saltwater fish have to drink water more actively and, as their surroundings are saltier than their insides, will expel a more concentrated urine.
So what if you filter it? Again, sorry to disappoint, the answer is no. The dissolved salts, ions and molecules, like urea, that are present in urine are too small for backpacking filters and even purifiers to remove.
“When urine combines with chlorine, it forms chemical compounds that can be harmful to your eyes, skin and respiratory system.” In virtually every instance then, it's probably better to hold your bladder until you can use a restroom instead of peeing in a public pool.
Yes, fish experience both physical and emotional pain. Scientists say that it's likely a different type than what humans experience, but it's pain nonetheless. Fish have nerve cell endings called nociceptors, which alert their bodies to potential harm such as high temperatures, intense pressure, and harmful chemicals.
Neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain. Fish, like “higher vertebrates,” have neurotransmitters such as endorphins that relieve suffering—the only reason for their nervous systems to produce these painkillers is to alleviate pain.
Can you just urinate straight into the fish tank? Sure, but the problem is that since that urine will take a while to convert into ammonia you will have no way of telling just how much potential ammonia you have in there. The levels will read very low, and then all of a sudden one day they will explode.
A hard hit to the head
It consists in hitting a fish's head with a blunt, heavy object that will stun it. A method used to kill large fish species but unfortunately not always effective. Decapitation should be applied after hitting the fish. If successful, this method of euthanizing fish kills them immediately.
A quick blow to the head
Since it's an instantaneous kill, the fish does not suffer for several minutes on shore before dying, as with some other methods. This technique is relatively painless, and also clean for the angler. If you're out in the field without gadgets, a rock will do the trick.
Even if this stuff did work as an attractant, it's not worth the impact to the environment. The WD-40 company has directly stated that they don't recommend using their product as a fish attractant.
“People think that goats are chasing them when really they're just following them, waiting for a handout.” But mountain goats aren't alone in their quest for liquid gold. A surprising number of creatures—from reindeer to locusts—have a known affinity for human urine.
So unfortunately, peeing in your garden won't repel them! It is thought that since we are not their natural predators, they know they do not need to avoid us and our scents. On the other hand, foxes are a natural predator to mice – so fox urine is much more likely to deter them.
A fishy smell in pee can result from dietary factors, an infection, and other health issues. It can also be a sign of trimethylaminuria (“fish odor syndrome”) which often has a genetic cause. If fishy-smelling urine is the only symptom, a person may want to wait for a couple of days to see if it clears up.
If you want to know how to get rid of ammonia smell, you'll need white vinegar, baking soda, and hydrogen peroxide. Use vinegar to spray the area with the odor. The baking soda will remove the smell from carpets. Mix the peroxide with water to clean the area with ammonia.
Ammonia may be present in drinking-water as a result of disinfection with chloramines. The presence of ammonia at higher than geogenic levels is an important indicator of faecal pollution (5).
Even the smallest amount of ammonia can cause gill damage in fish and extremely high levels are oftentimes fatal. But if you can catch this problem very early in its progress and treat the water immediately, the fish can live normally. Fish treated for ammonia burns will respond to treatment within three to five days.
