A fish controls its depth by increasing or decreasing the amount of air in its swim bladder.
When a fish has more air in the swim bladder, it is more bouyant and rises to the surface ,but when it lets out the air and the swim bladder fills with water, it becomes less bouyant so the fish sinks.

What depth fish can live?
the maximum depth fish can live is 400 meters under water
Why would the depth suddenly change if the equipment were detecting a shoal of fish?
The depth would change if the equipment were detecting a shoal of fish because the sonar waves emitted by the equipment would bounce off the fish, leading to a different reading. This could make it appear as if the water was shallower than it actually is due to the presence of the fish in the water column.
What water depth does a puffer fish live in?
Depth of 1.5-2 m
Why the position of the fish inside the water seems to be at less depth than of its actual position?
Light coming from the fish under water deviate from its original path due to refraction phenomenon and its image is displaced from its actual position. The image of fish is appeared at shallower depth than its actual depth
What do the side fins do for a fish?
They assist in stabilizing the fish so that it doesn't roll side to side. It also helps it change its depth in the water working like a wing so it can move up and down.
How can currents help the fishing industry?
the fish like warm or cold water. the currents tell were the fish are. like what depth
Why does velocity of water change with depth?
The velocity of water changes with depth due to variations in pressure and friction. Near the surface, water velocity is typically faster due to less friction, while deeper in the water column, velocity may decrease due to increased pressure from the weight of the water above. This change in velocity with depth is also influenced by factors such as the slope of the river or ocean floor and the density of the water.
Type of entry used for unknown depth in cloudy water?
A weighted line or a downrigger can be used to fish at an unknown depth in cloudy water. This equipment helps to accurately control and adjust the depth of your bait or lure, increasing your chances of catching fish in these conditions.
How do you change the water in the tank if one fish dies and one lives?
put the live fish in a bag filled with water and change the tank then put the fish back in.
How much water is in a fish tank of width 29 depth 15 and width 13?
(INCHES)
Which information is most important when passing near a lighthouse?
Depth of water
Are PFD's more buoyant in deep water than in shallow water?
No, the buoyancy of a PFD does not change based on the depth of the water. The buoyancy of a PFD is based on its design and materials, not the depth of the water. It will provide the same level of buoyancy regardless of the water depth.
