A short description about magur fish.The walking catfish (Clarias batrachus) is a species of freshwater airbreathing catfish native to Southeast Asia, but also introduced outside its native range where it is considered an invasive species. It is named for its ability to "walk" across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it has the ability to use its pectoral fins to keep it upright as it makes a wiggling motion with snakelike movements.[2] This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams and rivers, flooded rice paddies or temporary pools which may dry up
In aquatic animals such as fish respiration takes place through special respiratory organs called gills, however lung fish respiration takes place through lungs. Gills are present on both the sides of the head of fish. The gills are covered by gill covers also called operculum. When the fish open its mouth, water is drawn into the buccal cavity and passed through the gills. The gills contain special type of cells that absorb the oxygen present in water. The absorbed oxygen is then supplied to all the cells of body through blood. In the cells, oxygen is converted into carbon dioxide and returned back to gills through blood. Ultimately, the gills release the carbon dioxide in water passing through them.
Respiration in Fish
The gills of fish are very efficient; it is estimated gills can extract about 80% oxygen dissolved in water. In addition to the respiratory organs, the gills have an important role in maintaining the right balance of salts in the body.
Almost all natural bodies of water bear fish life, the exceptions being very hot thermal ponds and extremely salt-alkaline lakes such as the Dead Sea and Great Salt Lake. The fishes belong to the most numerous and diversified group among vertebrates. They dominate the water bodies of the world through a variety of morphological, physiological and behavioral adaptations. They have been in existence for more than 450 million years. A total of 24618 species of fishes belonging to 482 families and 4258 genera have so far been described. About 58% of the fish species are marine while 41% are freshwater inhabitants and 1% migrants. In our Indian region alone, there are 2,500 species of which 930 are inhabitants of freshwater and the rest live in the seas. In other words, India harbours 11.5% of the fish fauna so far known in the world. There are over 800 living species of sharks and rays, 30 species of chimaeras and ratfishes, 6 species of lung fishes, 1 species of coelacanths, 36 species of long ray finned bichirs, sturgeons and paddlefishes. The Neopterygii are the rest of the known species of modem fishes. All these fishes inhabit various niches in the aquatic environment. The diversified habitats of fishes include open oceans, deep oceanic trenches, nearshore waters, saline coastal embayments, brackishwaters, estuaries, intermittent streams, tiny desert springs, vernal pools, cold mountain streams, lakes, ponds, etc.
Effects of Noise Pollution on Wild Animals.pptxhafiz muhammad
Our noisy world is harming wildlife. Traffic, construction, and other human activities create a cacophony that disrupts how animals use sound. Animals rely on sound for everything from finding mates to catching prey. This noise pollution makes it hard for them to hear each other, like yelling over a crowded room. Predators miss out on meals, while prey become more vulnerable. The constant din also stresses animals, weakening their immune systems and even affecting reproduction. In worst-case scenarios, animals may abandon their homes entirely to escape the racket. By keeping noise levels down, we can create a quieter world where wildlife can thrive.

How to Prevent and Reduce Sound Pollution / Noise Pollution
A sound, especially one that is loud or unpleasant or that causes disturbance.
Noise pollution is the disturbing noise with harmful impact on the activity of human or animal life. The source of outdoor noise worldwide is mainly caused by machines, transportation systems, motor
vehicles engines and trains. Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
Sound becomes unwanted when it either interferes with normal activities such as sleep, conversation, or disrupts or diminishes one's quality of life.
Noise pollution affects both health and behavior. Unwanted sound (noise) can damage psychological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.
Chronic exposure to noise may cause noise-induced hearing loss.

3. What is noise?
Noise is unwanted sound considered
unpleasant, It is indistinguishable
from desired sound, as both are
vibrations through mediums such as
water or air. The difference arises
when the brain receives and
perceives sound.
4. TYPES OF NOISE
Continuous noise
It is the noise that
produced continuously
without any interruption.
Impulsive noise
Venus has a beautiful
name, but it’s terribly hot
Intermittent noise
It is a noise level that
increases or decreases
rapidly
Low- Frequency noise
It’s make up part of
the fabric of our daily
soundscape.

5. HOW DOES SOUND EFFECT BEHAVIOR?
Noise pollution impacts the health and well being of wildlife. Loud noise cause the
Caterpillar’s hearts to beat faster and bluebird to have fewer chicks.
Animals use sound for variety of reasons:
• To navigate
• Find food
• Attract mates
• Avoid predators
• Convey warning
• Defend territories
Noise pollution makes it difficult for them to
accomplish these tasks, Which affect their ability
survive.
6. • ANIMAL BEHAVIOR INCLUDES ALL THE WAYS
ANIMALS INTERACT WITH OTHER ORGANISMS AND
THE PHYSICAL ENVIRONMENT.
• BEHAVIOR CAN ALSO BE DEFINED AS A CHANGE IN
THE ACTIVITY OF AN ORGANISM IN RESPONSE TO
A STIMULUS
• SOME BEHAVIORS ARE INNATE, OR GENETICALLY
HARDWIRED, WHILE OTHERS ARE LEARNED, OR
DEVELOPED THROUGH EXPERIENCE. IN MANY
CASES, BEHAVIORS HAVE BOTH AN INNATE
COMPONENT AND A LEARNED COMPONENT.
• BEHAVIOR IS SHAPED BY NATURAL SELECTION.
MANY BEHAVIORS DIRECTLY INCREASE AN
ORGANISM'S FITNESS, THAT IS, THEY HELP IT
SURVIVE AND REPRODUCE
ANIMAL BEHAVIOUR
8. Anthropogenic Noise Pollution
➔Anthropogenic: originating in human activity.
➔Noise pollution: Different sounds and noises that disrupt the activity and
balance of human and animal life.
“Noise pollution consists on an array of disruptive sounds “
● Common Sources of noise pollution
1. Road Traffic
2. Aircraft noise
3. Railway noise
4. Construction and industrial noise
5. Active sonar devices
6. Seismic surveys for Oil
9. Terrestrial Noise Pollution
Community Noise
●is non industrial noise
●example roadway noise,
construction, public work and
neighborhood noise
●This noise comes from restaurant,
cafeterias, from live or recorded music;
sport events including motor sports;
playgrounds; car parks; and domestic
animals such as barking dogs.
Occupational Noise
●is industrial noise pollution
●example rotors, electrical
machines, blasting, and
pneumatic equipment
●Generated in ship-building,
mining, railroad work, welding,
and construction
10. Air Noise Pollution
Aerodynamic noise— from the
airflow around the surfaces of the
aircraft, especially when flying low at
high speeds.
Sources:
• Airports
• Residential planes
• Military aircrafts
11. Marine Noise Pollution
Sources:
• Ships – produce acoustic “fog” by
producing low-frequency sound
between 10 Hz and 1 kHz
• Sonar Devices – disrupts
echolocation used by animals like
whales and dolphins
• Seismic Surveys – produce loud
blasts of sound within the ocean
12. Ships
➔Ships tend to produce low- frequency
sounds between 10 kilo hz to 1 kilo
hz
➔This constantly generates an acoustic
“fog” masking natural animal sounds.
➔This type of lower level noise can
cause chronic illnesses in marine life
13. Sonar
➔Sonar is a technique that uses sound
propagation to navigate, communicate
with or detect objects on or under the
surface of the water, such as other
vessels.
➔Naval Sonars produce one of the loudest
underwater sounds.
➔Sonar sounds can be as loud as 235
decibels, while the average underwater
sound goes up to only 120 decibels
14. Seismic Surveys
➔ Seismic testing involves blasting the
seafloor with high-powered air guns (a
kind of powerful horn) every 10 seconds
and measuring the echoes
➔The “source level” of most air gun
arrays can be 200 to 240 decibels
➔These blasts disturb, injure and kill
marine wildlife

Animal Behavior?
16. 16
How noise Pollution?
Impacts of noise pollution on animals;
Noise pollution makes some animals more vulnerable to
predators , it can also have opposite effect.
Unpleasant sounds also cause negative behavior in animals.
Noise means stress and impairs the animals' immune
system which makes them more susceptible to illness in
general. Ocean noise pollution also causes
marine animals to flee and abandon valuable habitats,
either because of direct impact or because they have to
follow their fleeing prey.
High sound levels will interfere with their communication
and can induces fear, which can force species to abandon
their habitat. In loud places, studies have found that: High
intensity sound induces fear, forcing animals to abandon
their habitat.

Insects
Insects are involve in pollination, soil aeration
and they create Biological Foundation.
1- Caterpillar ; Noise cause the collision of long tentacles.
Noise raise their heart beat and make them scared as they
feel obstacles in metamorphosis.
2- Honey Bee; They get bothered by the massive intensity of
noise( 300hz to 1kHz). Noise put these bees in shock.
3- Grasshopper; Noise are upsetting their matting system.
Face difficulties in sending signals.
4- Spider; They get fereeze when exposed to low frequency
of sounds. They also don’t tolerate the high
pitched vibration of a vacuum.
18. 18
Animals
Animals are our companions, our workers, our eyes
and ears, and our food. They appear in ancient cave
paintings, and on modern commercial farms. We
have domesticated some of them, while others
remain wild and are sometimes endangered by our
activities.
1- Elephants ; They use infrasonic sounds to communicate
but noise producing activities are leaving disrupting
elements.
2- Dogs; Just as in humans, loud noises can harm the
delicate structures of a dog's middle and inner ear. "Most
commonly, noise-induced hearing loss results
from damage to the hair cells in the cochlea that vibrate in
response to sound waves," Foss said.
3- Cats; just as in humans, all cats have some degree of
normal fear when they hear loud, sudden or strange noises.
It's part of our survival instinct. Some cats, however, are
especially sensitive to noise or display exaggerated
responses to certain sounds.
19. 19
Aquatic animals
Unwanted sound, or noise, can have a
large impact on the marine environment,
because noise can blanket a very large area,
potentially preventing fish or whales from hearing
their prey or predators, finding their way, or
connecting with mates, group members, or their
young.
1- Dolphins ; These noises not only disrupts communication,
they can cause temporary hearing loss and permanent
tissue damage in dolphins as well. Noise disrupts
communication between dolphins, hinders their navigation
patterns, and inhibits their ability to find food; ultimately
causing them to suffer from chronic stress.
2- Whales; Noise in the form of naval sonar or seismic
surveys can be deadly to cetaceans in at least some
cases. Whales have been found to die within hours, by
stranding or deaths at sea, from even a transient and
relatively brief exposure to moderate levels of mid-frequency
military sonar.
3- Fishes; Noise change the direction of their migration
route. It could also mask natural sounds that are important to
the fish, such as communication sounds from other fish,
20. 20
Birds
Researchers suggest that noise pollution
affects their behavior, their fitness, breeding and
growth, and often leads to chronic stress. ...
Scientists say that constant noise may form an
acoustic blanket muffling the audio cues birds rely
on to detect predators, competitors and their species.
1- A bird startled by a loud noise will usually take off
and can bang into a wall or other object,
which can definitely kill them
2-Hearing loss and rapid increase in heart rate are some of
the ill-effects of noise pollution on birds. High
intensity sound induces fear, which can force species to
abandon their habitat.
3-The researchers found that noise pollution also has a
huge impact on the natural migration of birds.
Many birds will avoid noise polluted areas during migration
which in turn, affects where they will establish their long-
term homes to raise their young.
22. Harmful Impacts of
Human Noise
● Noise can seriously damage the wildlife . There
are many ways in which noise can indirectly
have a heavy impact on the wildlife . Following
are some of them.
• Masking :It is the inability to hear important
environmental clues and animal signals.
• Physiological Impacts : Noise causes and
increase in heart rate and respiratory difficulties
while also at the same time gradually increasing
stress
• Behavioral Impacts : It results in different
behavioral patterns which could also result in
abandonment of territory and even loss of ability
to reproduce.
23. Harmful Impacts of Human Noise
• Ecological Impacts : It leads to migration of
birds which also disturbs the ecosystem.
• Annoyance : It creates annoyance to the
receptors due to sound level fluctuations. The
periodic sound due to its irregular occurrences
causes displeasure to hearing and causes
annoyance.
• Loss of Hearing : Long exposure to high sound
levels causes loss of hearing. This is mostly
unnoticed but has an adverse impact on
hearing function.
• Causes Stress/Fear : The Chimes of vehicle
horns strikes fear in animals and wards them
off having an detrimental effect on them.
24. Impacts on Animals
• Nervous System : Noise pollution damages the
nervous system of animal. Animal looses the
control of its mind. becoming dangerous.
• Increases Mortality : increasing risk of mortality
by changing the delicate balance in
predator/prey detection and avoidance, and by
interfering with their use of sounds in
communication especially in relation to
reproduction and in navigation.
• Lombard Vocal Response :Noise also makes
species communicate louder, which is called
Lombard vocal response. Scientists and
researchers have conducted experiments that
show whales' song length is longer when
submarine-detectors are on.
25. Impacts on Animals
Beached Whale
● One of the best known damage caused
by noise pollution is the death of certain
species of beached whales, brought on
by the loud sound of military sonar.
European Robins
● European Robins living in urban
environments are more likely to sing at
night in places with high levels of noise
pollution during the day, suggesting that
they sing at night because it is quieter,
and their message can propagate through
the environment more clearly.
26. Impacts on Health
Problems of Noise Pollution Noise pollution makes men more irritable. The effect of noise
pollution is multifaceted & inter related. The effects of Noise Pollution on Human Being,
Animal and property are as follows
● FATIGUE PUPIL DILATION : Noise Pollution causes dilation of the pupil of the eye
because of Noise Pollution, people cannot concentrate on their work. Thus they have
to give their more time for completing the work and they feel tiring.
● Aggressive Behavior Digestive problems : Noise above 80 dB may increase
aggressive behavior. Annoyance is defined as a feeling of displeasure associated with
any agent or condition believed by an individual to adversely affect him or her. It also
causes digestive spasms and stomach disorders
● HEARING IMPAIRMENT : Levels greater than 165 dB, even for a few milliseconds,
are likely to cause acute cochlear damage. There is also general agreement that
exposure for more than 8 hours to sound levels in excess of 85 dB is potentially
hazardous

PREVENTIVE
MEASUREMENTS
28. NOISE MANAGEMENT
“Noise Management” is to maintain low noise exposures in order to assure that
the health and well-being of humans as well as animals is protected.
Noise can be tackled through :
Reduction at
source
opt for
alternative
quieter
methods
Prevention or
reduction of
propagation
29. ● These steps must be taken in order to effectively and efficiently control noise
pollution.
● . Identify the sound sources
● . Identify the path of the noise from the source
. Determine the sound level of each source
. Determine the relative contribution to the excessive noise of each source
and drank the source accordingly
● . To obtain significant noise attenuation the dominant source should be
controlled first
● Know the acceptable exposure limits identified in the health and safety
legislation and quantify the necessary sound reduction
● Identify solutions by taking into consideration the degree of sound
attenuation, operation and productivity restraints and cost
30.
31. NOISE
MITIGATION
" Noise Mitigation" is a set of strategies
adapted in order to reduce exposure to
noise and noise pollution.
● The exposure to noise can be
reduced by;
● eliminating the source of noise
● substituting the source with a
quieter one
● applying engineering modifications
● using administrative controls
● trying to prevent propagation
32.
33. ELIMINATION
● Elimination is a process that eradicates the
noise source it is the most effective way to
prevent risk
● It should always be considered
when designing new work equipment on
machinery
● It includes avoiding the use of noisy
machinery , outsourcing the noisy work
process
● Preferring natural means of
transportation, communication ,navigation
and life as a whole over the hazardous
artificial ways of life
● Elimination is the control of noise at its
source
34. SUBSTITUTION
● Substitution is a process of
replacing noisy machinery or
equipment with quieter
alternatives
● when elimination is not
possible substitution of the
noisy machinery or equipment
for quieter ones may be the
next best alternative to
protect living organisms from
exposure to noise
35. ENGINEERING CONTOLS
● engineering controls are all about making changes to
processes, machinery or equipment so that the
environment is exposed to less noise
● for example using screens barriers enclosures and
absorbent materials
● enclosure of noisy machinery with sound absorbing
material
● avoiding metal to metal contact by using plastic
bumpers
● using absorbent lining on surface is to cushion the fall or
impact of objects
● fitting sound absorbing materials to hard reflective
surfaces
● using conveyor belts rather than rollers
● using acoustical silencers in intake and exhaust systems
● maintaining optimal speed of machinery or its particular
components
36. ● can you please sing lose rotating parts worn bearings and gears
● undertaking regular maintenance on equipment
ADMINISTRATIVE CONTROLS
● Administrative controls are the way work is organized to reduce either the
number of organisms who are exposed or the length of time they are
exposed to noise
● Administrative controls should be used when it is not possible to reduce
noise exposure through elimination ,substitution or engineering noise
control measures
● Increasing the distance between noise sources and the habitat of living
organisms
● Providing sufficient information instructions and training to the workers for
the proper use of work equipment and the knowledge of the place where
the equipment should be used
37. ● Each and every person that works
with noise producing equipment
machinery gadgets and vehicles should be
aware of harmless decibel standard as
well as the harmful impact of high levels
of noise on living organisms specially
animals
38. LEGISLATION
• In Pakistan unfortunately there is
no legislation to deal with noise
emanating from railway engines,
aircraft ,airport ,industrial or
constructional activities activities
• The absence of national standards
for noise is one of the biggest
hurdles in the way to protect our
environment and biodiversity
39. • Even though the rapid spread of human development
an associated anthropogenic noise have impacts on
wildlife and biodiversity, it is not always logistically,
politically or economically feasible to eliminate or even
minimize noise
• The realistic and more common policy approach
should be to set noise standards in the hope of
limiting the level of noise that development produces
• the production of noise can then be reduced
structurally or operationally to meet these standards
• regulations necessarily balance the economic and
environmental tradeoffs involved in allowing
development to proceed and as a general route the
more information that can be brought to bear on this
balancing process the better
• The first priority in the development of noise
standards should be the protection of biodiversity an
environment
CONCLUSION
