Top best answers to the question «How to detect fish underwater»
Fish finders detect the presence of fish primarily by detecting the air in their swim bladders. The air conserved in the swim bladder changes the sound path and reflects energy back. The fish finder detects this reflected energy and converts it into fish images on the screen.

Those who are looking for an answer to the question «How to detect fish underwater?» often ask the following questions:
🌊 Can you detect emeralds underwater?
How can you tell if an emerald is a genuine emerald?
- Examine the edges of the emerald carefully. A genuine emerald has a good amount of hardness, varying from 7.5 to 8 on the Mohs scale. If the edges seem worn out or damaged, it implies that what you're looking at is probably glass.

🌊 How to detect underwater earthquakes?
- For earthquakes in the ocean, hydrophones can be used to detect and measure submarine earthquakes. Seismic energy from submarine earthquakes is converted into acoustic energy at the seafloor-water boundary. A Tertiary wave (or T-wave) is the acoustic signal from these earthquakes. A T- wave typically has frequencies ranging from 4 to 50Hz.

🌊 How do underwater seismologists detect underwater explosions?
- They are extremely sensitive and pick up acoustic waves from underwater events, including explosions, vast distances away. T-phase stations are located on oceanic islands and use seismometers to detect the acoustic waves generated by explosions in the oceans.

We've handpicked 28 related questions for you, similar to «How to detect fish underwater?» so you can surely find the answer!
Can fish drown underwater?- The answer is yes, fish can drown underwater by getting suffocated. Similar to humans, fish also cannot survive without oxygen. Oxygen plays important role in producing energy which is essential for the metabolism in living organisms.
If you are trying to ask .... " If they can hear us then its yes and no" However fish can communicate with EACH OTHER.
Can a fish drown in a bowl of water?
- You may be wondering: can fish drown? The answer is yes, fish need oxygen to survive just like humans. If the water a fish is swimming in becomes devoid of oxygen, a fish can drown in water; this can frequently occur if you leave a goldfish in a small bowl without a running filter.
Unlike humans who don't smell much underwater, fish actually do have rather good olfactory abilities. Fish use their sense of smell to find food, avoid predators, identify each other, spot safe habitats, and even locate spawning grounds.
Do fish bleed underwater?- Do fish bleed underwater? yes, but submerging a cut in water causes the blood to flow/diffuse away in a way that air exposure doesn’t, so the platelets would not fix in place and scab nearly as quickly. Should you bleed snapper? If you plan to keep your fish to eat, kill it quickly!

Do fish blink underwater?
Fish don't “blink” their eyes quite like humans do… So, what about fish? Obviously fish live underwater so the risk of their corneas being exposed to the air is not an issue to them. So they do not have eyelids.
Do fish breath underwater?Do fish breathe out carbon dioxide?
- Fish don't breath using lungs like humans but they absorb dissolved oxygen from the water through their Gills and expel carbon dioxide also via their gills.

Do fish breathe underwater?
Does fish breathe underwater?
- The lungs of mammals would not work very well for a fish, because one breath underwater would fill them with fluid and make them useless. Nonetheless, fish need oxygen to breathe, too. In order to remove oxygen from the water, they rely on special organs called "gills.". Gills are feathery organs full of blood vessels.
- The answer is yes, fish can drown underwater by getting suffocated. Similar to humans, fish also cannot survive without oxygen. Oxygen plays important role in producing energy which is essential for the metabolism in living organisms.
Fish live underwater… Fish do not breathe air. They get the oxygen they need from the water they live in. Fish have special filters in the sides of their body called 'gills' that act as their 'lungs'.

How fish see underwater?
Can fish see underwater/in the dark?
- This proliferation of Rh1 genes may help deep sea fish to see in the depths of the ocean. Also, to avoid predation, many species are dark to blend in with their environment. Many deep-sea fish are bioluminescent, with extremely large eyes adapted to the dark.
- By determining the time between the emission of the sound pulse and its reception, the transducer can determine the range and orientation of the object. Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales.
- This technology also relies on sound waves to detect objects. However, sonar is typically used underwater. This sonar image shows the entrance to Portsmouth Harbor, N.H. Lower areas are in blue, higher areas in red. NOAA/NOS/Office of Coast Survey
- Underwater Dock & Fish Lights to Attract Fish Anywhere! How Do Fish Lights Work? Our fish lights reflect off of small particles in the water that attract baitfish. As a result, these baitfish attract larger fish! So, these dock lights truly bring your backyard to life! The species of fish you will see depends on your area.
- Absence of boiling sound makes it difficult to detect an underwater eruption, even with the help of hydrophones. These days, remote operated vehicles are used to study the effects and patterns of underwater volcanic eruptions.
Is a fish under water considered'wet or'dry?
- Humans are dry in contact with air, but if we come out of the water, we are wet. If a fish is out of the water, it is wet.
Wetness can only be considered in a dry environment. On that basis, a fish in the water is not wet. But take a fish out of the water, you see water on its skin, so, it is not dry, it is wet… The same swallowed water is excreted through the gills to keep the fish dry and to manipulate gravity, so it is not wet.
Are fish wet underwater science?When is a fish underwater, are they wet or are they dry?
- One argument is the fish is dry because the fish is constantly surrounded by water so it isn't considered wet until it is removed from the water. The other argument is the fish is wet because water = wet.

Are fish wet when underwater?
- Is a fish wet underwater? According to the scientists, the fish are covered by a kind of single layer that keeps them dry. When you take the fish out of the water it is when it is considered wet, when it is already out and touches the air it is when it can be said that it is wet, because now there is the concept of wet and dry. Can fire be wet?
- Taking a fish out of water will naturally cause it to suffocate, as it isn’t able to pull oxygen from the air with its gills. As for how a fish could suffocate underwater, this can happen in a couple of ways.
Yes, all fish can breathe underwater, though some fish are able to breathe air as well, for short periods of time. There are certain aquatic mammals, such as dolphins and whales, which can NOT breathe under water. These can often be mistaken for fish, but they are mammals, like humans.
- Water is not airtight that's why fish can breath in it so I think a dog would be able to smell it. Maybe if you submerged it in coffee would be even better cuz you can't see through it. Also maybe add a couple spoonfuls of bleach to the water
Large Ocean Fish
As mammals, they have lungs and can hold their breath for long periods of time underwater They can also live for months on land, but will eventually have to return to the water to provide support for their bodies, or else their weight will crush their organs.
Science tells us that fish have eyes similar to humans, but they also have protective film over their eyes so that they can see more clearly underwater. Their eyes have rod and cone cells on their retinas, so we know that they can see color as well as in shades of grey, light and dark.
