4. Introduction
Aquaculture engineering is a multidisciplinary field of engineering that
aims to solve technical problems associated with farming aquatic
vertebrates, invertebrates and algae.
Aquaculture engineering requires knowledge of the many general
aspects of engineering such as material technology, building design and
construction, mechanical engineering and environmental engineering.

5. Basic Criteria For Site Selection In Aquaculture Engineering

6. Physical Criteria
Meteorological and hydrological information
Air, Temperature, Rainfall, Evaporation, Sunshine, Speed and Direction of winds,
Floods, Water.
Bottom Topography
 The low land may be made up of potential acid sulfate soils.
 Deeper ponds cannot be built and complete drainage is impossible.
 Construction costs in swamp land are always higher.
Climate:
The coastal aqua farm should be located in areas with no pronounced dry or wet
seasons.

7. Soil Type
 Sandy soil
 Clay soil
 Silt soil
 Peat soil
 Chalk soil
 Loam
Physical Movement of water
Temperature, turbidity, colour, water movements, water conditions and
depth; stratification of water; tidal amplitude and its seasonal changes
in coastal sites.

8. Soil Quality
Content Amount
pH 6.5 to 8.5
Total Nitrogen 0.1%
Total Phosphorus 0.1%
Organic Carbon >1.0%
Free Calcium Carbonate 5%
Sandy and peaty soils are not suitable because they do not hold water
and are not good dike materials
Chemical Criteria

9. Some Important Water Quality Parameters

10. Biological Criteria
Characteristics of Culture Species
It should have a fast growth rate
It should have ability to feed on natural food and artificial diet.
It should be hardy and resistant to disease.
It should be herbivorous or omnivorous,
Feed availability:
Obtaining feed from the nearest source and transporting these feed to the
farm site within the shortest possible time.
Seed supply:
Proximity to sources of wild fry and/or hatcheries reduces transport costs of
the farmer as well as transport stress of the fry.

11. Engineering Criteria
Filtration Facilities
Mechanical filters , which remove particulate debris from the water, need to be
checked and cleaned regularly.
Biological filters enable bacterial colonies to propagate and break down wastes
Electricity :
To ran an aquaculture farm electricity is playing a vital role .The site must have power
facilities.
Work Shop Facilities
An ideal aquaculture farm should have a workshop where the labour can receive any
kind of practical mechanical knowledge about different kinds of technologies (Pump,
Aerator, Generator, Filtration etc.) which are mainly used in aquaculture.

12. Pump and Pipe Facilities
 To construct an aquaculture farm the site must have sufficient
requirement of pump and pipe facilities.
 Three types of pumps are used in aquaculture, the most common is the
centrifugal (radial flow) pump .
Aeration
 Water aeration is the process of increasing or maintaining the oxygen
saturation of water in both natural and artificial environments
 The main purpose of aerators is providing oxygen and mixing to
disperse oxygen throughout the pond

13.  Information on the local financing methods or credits
 Human interference (Poaching)
 Religion Effect
 Availability of construction materials
 Location of markets for the produce and determination of demand
 Availability of organic and artificial fertilizers, drugs and chemical
materials
 Availability of supplementary feeds
 Costs of equipment, materials, feeds, etc. needed for running the
project
 Availability of suitable transport facilities

14. Other Criteria
 Accessibility
 Availability of manpower
 The existing and future sources of pollution
 Legal aspects
 Transportation
