BACKGROUND
Aqua culture is mainly effected by
DO control
Temperature control
Biological filtration
Water management
Traditional vs modern aquaculture
DO CONTROL
DO is important chemical parameter in aquaculture .
If DO level drops in a water body then the fishescould not survive.
Over a matter of hours, or sometimes evenminutes, DO can change from optimum to lethallevels.
Three factors effect the DO
oxygen is not very soluble in water so water has onlya limited capacity to “hold” oxygen.
the rate of oxygen use by fish and organisms living inthe pond mud can be high.
oxygen diffuses very slowly from the atmosphere intoundisturbed water
DO CONTROL
Dissolved oxygen levels can be managed with
aeration.
Response time for taking corrective measures is
short.
The Do level maintained should be 3-5mg/L.
If DO<4mg/L then pressure increases on fishes.
If DO <= 0.6 mg/L then it causes death of fishes.
To react to the situation, a fast and reliable
method of measuring DO should be done and
should activate the aeration.
TEMPERATURE CONTROL
Fishes are cold blooded and keep same
temperature around it.
The growth, feeding reproduction of fishes are
effected by temperature and metabolic rate in
fish doubles with increase in temperature.
Temperature increase make fishes irresistible to
diseases.
The optimum temperature to be maintained is
between 23 to 30o C.
As the temperature increases in the water the
DO decreases.
TEMPERATURE CONTROL
Axial flow devices on surface of water and air
diffusers at the bottom can propel water up ad
down to maintain temperature.
BIOLOGICAL FILTRATION
In many ways ammonia is produced in water.
Release of nitrogenous waste by fishes and other aquatic organisms from the gills
Urine and solid wastes.
Excess feeds left in water
Ammonia is toxic to fishes and result in poor growth and lower resistance to diseases.
The amount of ammonia is measure with PH (potential of Hydrogen) level.
PH value ranges from 0 to 14. Less PH more ammonia present.
The PH>6 and <8 in water and continuous monitoring is needed to maintain it.
WATER MANAGEMENT
The maintenance of good water quality is essential forboth survival and optimum growth of cultureorganisms.
Most of the water quality problems can be solved withadequate water exchange.
When stocking density increases, water should besupplied to maintain good water quality.
Besides aeration, sanitizers, zeolite water enhancer ,water exchange is still the most effective and widelyemployed method.
water exchange is used to adjust salinity as desired,to remove excess metabolites, to keep algae healthyand producing ample oxygen and to regulate pondwater temperature.
WATER MANAGEMENT
Controlled water exchange.
Co-ordinating water exchange and fertilization to
maintain populations of algae.
Avoid overfeeding through proper management of
feeding.
Aeration.
Continual or periodic removal of accumulated
organic material from the pond bottom.
Maintenance of a high density bacterial flock i.e.
probiotics combined with water circulation and
aeration.
NEWS
Hindu: The extremities in weather conditions delivered a deadly blow
on Jampana Rama Raju, a fish farmer from Tadinada village in Undi
mandal of West Godavari district. Around 5-6 tonnes of the fish in his
100-acre pond worth Rs. 5 lakh died in the last two days due to
deficiency in oxygen levels caused by sudden changes in the climate.
TRADITIONAL VS MODERN AQUA CULTURE
TRADITIONAL AQUA CULTURE
TRADITIONAL AQUA CULTURE
Farm scale will be larger and larger
More Human /labor required
Labor cost increasing
Maintenance of water resources and environment
is difficult.
Problems due to lack of timely response from the
farmers.
Controlling the machines and tools is manual.
MODERN AQUA CULTURE
MODERN AQUA CULTURE
High productivity
Automatic operation
Facility controlled
Ecological and safety

APPLICATION OF IOT TO AQUA CULTURE
Monitoring DO levels
Monitoring PH values
Water management
Send the SMS to farmer about the status of
these values.
Farmer switches on/off the pumps, motors ,
aerators or the diffusers based on response.
Monitoring fishes behaviors using Digital image
processing application.
REQUIREMENTS
Intel Galileo board
Sensors
GSM module to send the SMS
Relay controllers
ARDUINO AND GSM
CIRCUIT DIAGRAM
ARDUINO SOFTWARE
Arduino boards are able to read analog or digital
input signals from different sensors and turn it into
an output such as activating a motor, turning LED
on/off and many other actions.
You can control your board functions by sending a set
of instructions to the microcontroller on the board via
Arduino IDE (referred to as uploading software).
You can simply use a USB cable for uploading the
program.
Arduino IDE uses a simplified version of C
ARDUINO BOARDS
Various kinds of Aurdino boards are available
depending on different microcontrollers used.
Boards differ in Operating Voltage, clock speed,
and number of Digital I/O, Analog & PWM pins.
All Arduino boards have one thing in common:
they are programed through the Arduino IDE.
SET UP THE ARDUINO IDE
Step 1 − First you must have your Arduino board
and a USB cable.
Step 2 − Download Arduino IDE Software and
unzip the file.
STEP 3 − POWER UP YOUR BOARD AND
CONNECT THE ARDUINO BOARD TO YOUR
COMPUTER
STEP 4 − LAUNCH ARDUINO IDE.
STEP 5 − OPEN YOUR FIRST PROJECT.
STEP 6-SELECT YOUR ARDUINO BOARD
STEP 7-SELECT YOUR SERIAL PORT
STEP 8- COMPILE & UPLOAD THE
PROGRAM TO YOUR BOARD
SAMPLE CODE TO CHECK PH VALUE AND
SEND SMS
void setup()
{
Serial.begin(9600);
pinMode(2,INPUT);
int send=0;
delay(500);
}
void loop()
{
int a= analogRead(2); // return 0 to 1023
int ph=Map(a, 0,1023,0,14); // ph value is between 0-14.
if(ph<7 && send==0)
{
SendTextMessage();
Send=1;
}
}
void SendTextMessage()
{
mySerial.println("AT+CMGF=1"); //to send the SMS in text mode
delay(100);
mySerial.println("AT+CMGS=\"+919949555555\"\r");
// change to the phone number you using
delay(100);
mySerial.println("The Ph value is more take necessary action");
//the content of the message
delay(100);
mySerial.println((char)26); //the ASCII code of the ctrl+z is 26
delay(100);
}
AQUA MONITORING SYSTEM IMPLEMENTED
IN PONDS OF KRISHNA DISTRICT
MONITORING FISHES
Capturing the images of fishes with water proof
cameras.
Enhancing the images using digital image
processing techniques.
Observing the movements, populations of fishes,
their productivity, etc.
ADVANTAGES OF THE SYSTEM
Timely intimation to the farmer through SMS.
Saves manual intervention.
Reduces the time in checking the parameters.
High productivity.
Reduction of cost.
Remote access to the system.
Data available for analysis.
FUTURE WORK
We at ANU enhanced the images. Need to do still more research to analyze the enhanced images for the betterment of farmers.
We have measured only the Do, PH, temperature and water levels.
Still there are more parameters like tubidity, humidity, ammonia etc that need to be analyzed.
Automatic feeding system.
Intelligent Prediction, warning and controlling of the parameters.
Disease early warning and remote diagnostics.
Mobile APP to control the aerators, water supply remotely by the user.
