Fish And Beer: A Curious Friendship

Fish can get drunk, and even become anti-social daredevils when alcohol is mixed with energy drinks, according to a paper published in the Journal of Psychiatric Research. A 2014 study by scientists at the NYU Polytechnic School of Engineering's Dynamical Systems Laboratory concluded that fish could get drunk in the same way as humans. In fact, a video from 2016 shows a fish gulping down beer from a can in Brazil.

However, it is important to note that fish do not drink alcohol in the same way that humans do. Instead, they absorb alcohol through their gills via a process called osmosis. While it may be tempting to try and get your pet fish tipsy, it is crucial to remember that high concentrations of alcohol can burn their sensitive gill tissue and skin, and even cause toxicity and death.

Fish absorb alcohol through their gills

Fish do not drink alcohol in the traditional sense, but they can get drunk. Fish absorb alcohol through their gills via a process called osmosis. Osmosis is a process of absorption or diffusion, which is how fish drink water. When alcohol is added to the water, it is absorbed through the gills, along with the water.

A 2014 study by researchers at the NYU Polytechnic School of Engineering's Dynamical Systems Laboratory found that fish can get drunk in the same way as humans. The study placed individual fish in water with different concentrations of ethanol alcohol (0.00, 0.25, 0.50, and 1.00%). The fish were then observed for changes in behaviour and motor skills.

The results showed that fish exposed to lower concentrations of ethanol became more energetic and swam faster, both on their own and when placed back with their school. The sober fish also swam faster to keep up with the drunk fish. However, fish exposed to the highest concentration of ethanol became slower and more lethargic, with some exhibiting confused behaviour.

The effects of alcohol on fish are temporary, and within a day, the drunk fish returned to normal. Nonetheless, it is important to note that too much alcohol can burn the gills and skin of fish and even cause death. Therefore, while it may be intriguing to observe the effects of alcohol on fish, it is crucial to prioritise their health and well-being and avoid exposing them to harmful substances.

Drunk fish may become more confident and assertive

Fish can get drunk, and they exhibit behaviours similar to drunk humans. They lose their inhibitions, swim faster, and become more assertive.

In a study, researchers at NYU exposed zebrafish to various environments of EtOH (a technical term for alcohol) to observe their behaviours. The highest concentration was only 1% EtOH. After getting the fish drunk, the researchers monitored their swimming trajectory and interactions with other sober fishes.

The researchers found that the drunk fish swam faster in a group setting than when observed alone. The sober fish also swam faster in the presence of a drunk fish, indicating that they were influenced by the drunk fish's alcohol-induced boldness and confidence.

The study also found that the most drunk fish tended to lag behind, likely experiencing the sedative effects of alcohol.

Therefore, drunk fish may become more confident and assertive, leading the group and influencing the behaviour of their sober peers.

Alcohol can be harmful or fatal to fish

Fish can indeed get drunk, and it is important to note that alcohol can be harmful or fatal to them. Fish do not drink alcohol in the traditional sense, but they absorb it through their gills via a process called osmosis. This means that when ethanol alcohol is added to the water in which a fish is swimming, the fish becomes drunk.

While it may be surprising that fish can get drunk, it is not surprising that they are affected by alcohol, given that it is a drug that influences the nervous system of many animals. A 2014 study by scientists at the NYU Polytechnic School of Engineering's Dynamical Systems Laboratory concluded that fish exhibit altered behaviour and motor skills when exposed to alcohol.

The study found that fish exposed to low concentrations of ethanol became more energetic and swam faster, influencing the other sober fish to swim faster as well. However, fish exposed to high concentrations of ethanol became slower, lethargic, and even confused. In addition to these effects, alcohol can burn the sensitive gill tissue and skin of fish, and cause toxicity and death, especially if it comes into direct contact with their gills without being diluted.

It is worth noting that the effects of alcohol on fish are temporary, and they return to normal within a day. Nonetheless, it is crucial to emphasise that experiments involving fish and alcohol should never be recreated outside of carefully controlled scientific conditions. While fish may be able to tolerate small amounts of alcohol, it is incredibly easy to add too much, which can have harmful or fatal consequences.

Fish can get drunk on beer

It is true that fish can get drunk on alcohol, just like humans and other animals. However, it is important to note that fish should never be given alcohol, as it can cause them harm and even kill them.

Fish do not drink alcohol in the same way that humans do. Instead, they absorb alcohol through their gills via a process called osmosis. Osmosis is a process of absorption or diffusion, and it is how fish breathe underwater and take in water. Therefore, when alcohol is added to the water that a fish is swimming in, the fish will absorb the alcohol through its gills and become intoxicated.

A study conducted by researchers at the NYU Polytechnic School of Engineering's Dynamical Systems Laboratory in 2014 confirmed that fish can indeed get drunk, and that their behaviour and motor skills are affected in a similar way to humans. The researchers exposed zebrafish to different concentrations of ethanol alcohol (ranging from 0.00%, 0.25%, 0.50%, and 1.00%) and observed their behaviour.

The results showed that fish exposed to lower concentrations of ethanol became more energetic and swam faster, both on their own and when placed back with their school. Interestingly, the sober fish also increased their speed to keep up with the drunk fish. On the other hand, fish exposed to higher concentrations of ethanol became slower, more lethargic, and displayed signs of confusion.

In addition to changes in swimming speed, the study also found that drunk fish exhibited altered inhibitory behaviour and leadership skills. Fish with a slight buzz threw their inhibitions out the window, showing little fear or hesitation. They also displayed signs of leadership, with their assertive movements steering the direction of the entire group.

While it may be tempting to speculate about the parallels between drunk fish and human behaviour, it is important to remember that these experiments should never be recreated outside of a carefully controlled scientific environment. Alcohol can burn the sensitive gill tissue and skin of fish, and even cause toxicity and death if the concentration is high enough. Therefore, while fish can indeed get drunk on beer, it is crucial to prioritize their health and well-being by refraining from exposing them to alcohol.

Drunk fish may be more likely to take risks

Fish can get drunk, and a study by researchers at NYU found that intoxicated fish may be more likely to take risks. The study exposed zebrafish to various environments of EtOH (a technical term for alcohol), with the highest concentration being 1% EtOH. The researchers then observed the behaviour of the drunk fish when placed in a group of sober fish.

The study found that the drunk fish swam faster when in a group setting than when observed alone. The sober fish also swam faster when in the presence of a drunk fish, indicating that the intoxicated fish became a leader and the sober fish followed.

In addition, the study found that when exposed to a predator, the drunk fish exhibited bolder and more aggressive behaviour. This is similar to the effects of alcohol on humans, where alcohol can reduce inhibitions and increase feelings of relaxation and euphoria.

Another study, published in the Journal of Psychiatric Research, found that zebrafish exposed to alcohol and energy drinks were more likely to venture towards a model of a natural predator compared to fish that were only exposed to alcohol or water. This suggests that mixing alcohol with energy drinks may increase the negative effects of alcohol, such as reducing fear and impairing judgement.

While it may seem surprising that fish can get drunk, it is important to note that fish absorb water and any additives in it through their gills via a process called osmosis. Therefore, when alcohol is added to the water that a fish is swimming in, the fish can become intoxicated.
