Process Of Seaweed cultivation
1. Seedlings are tied on ropes at a fixed distance and the ropes are tied parallel to the water movement between the two ends in the container like in Fixed off-Bottom method .
2. Water is filled to a suitable height through the inlet pipe .Outlet pipe shutter is opened and motor is turned on to ensure continuous water movement .Motor is run using the energy stored in the Solar Panel.
3. Thermostat and TDS meter is used to measure and control temperature and salinity from time to time.
4.After 45-60 days seaweeds are ready to be harvested.The entire ropes are removed together and seaweed is harvested.
5.The seaweeds can be processed for further use.

Benefits of our Prototype
1.Motor ensures water movement which prevents parasite growth.
2.The design is closed structure so that it prevents rabbit fish grazing.
3.Thermostat and TDS meter measures and controls temperature and salinity to the required range.This controls the spreading of Ice Ice disease which is caused due to sudden changes in temperature,salinity and other environmental factors.
4.Increase in Seaweed yield.

Water Temperature- best grown in the range of 25 °C to 30 °C
Salinity- minimum water salinity required is about 28 ppt (parts per thousand) or more
Water movement- moderate water movement

Seaweed can be processed for following uses:
1. Fertilisers and soil conditioners-has a good content of Nitrogen and Potassium
2.Animal feed-cattle,sheep,horse
3.Fish feed
4. Biomass for fuel
5.Cosmetics
6.Integrated aquaculture-source of raw material for agar industry
7.Wastewater treatment-remove heavy metals from water

We are working on creating an app which helps us to connect seaweed farmers,poultry farms and biodiesel plants. The app will help us to create a platform where all the three can sell and buy seaweeds at negotiable price. The video demonstrates the working of our app.

On time On target - Design Statement

Major problems
1) Shortage of nutritional food.
2) Insufficient land for cultivation.
3) increasing use of harmful pesticides.
4) use of heavy metal contaminated water that reduce crop yields.
5) climate change reducing crop yields.

We want to develop a method which should-
1) help mitigate climate change so that their is not much reduction in crop yields.
2) it should have the essential nutrients which are missing in the current modern day diet.
3) to have excellent fertilizer and pesticide which will not harm the soil.
4) in future, this will create a new market which will support farmers.
5) help in removing heavy metals from polluted water and soil.

From a consumer perspective-
1) it should be tasty and nutrition.
2) it should not heavy side effect.
3) it should be cheap and easily accessible.

Current scenario
while seaweed cultivation has started in south east Asia and other parts of the world, still india remains as a sleeping giant. It is that unfortunate India is importing agar-agar while she has huge wealth of seaweeds. We have more than 800 species of seaweed not even one species is taken up so far for cultivation on commercial scale.

Insight+Insight+Insight

Insight 1:
"Ice-Ice" disease is a major problem in seaweed farming. Affected plant parts become whitish,soft and eventually disintegrates. This is a result of sudden change in environmental conditions such as salinity,temperature and light intensity.Seaweed growth is dependent upon the factors like water temperature,salinity,turbidity and other environmental changes. Prolonged exposure of seaweed to the air (especially for Cottonii) and algal parasites also affect its growth.Moreover,grazing by fishes pose a big problem.We can design a structure that controls temperature,salinity,turbidity and prevent the growth of algal parasites.Along with this the structure should also prevent exposure to the fishes.

Insight 2:
It has been reported that seaweed increases iodine content and improves colour of the yolk of the egg of the poultry. Thus,significance of seaweeds as a feed for poultry and cattle or other animals has been recognised. Species like Ulva, Enteromorpha ,Gracilaria, Hypnea, Sargassum, Padina, Dictyota etc are used in cattle feeds.Poultry feed is also made by mixing seaweeds with fish meal.Uses of seaweed as animal feed increase fertility and birth rate.Seaweed and other algae is increasingly looking like a viable substitute. About 50% of seaweed's weight is oil, which can be used to make biodiesel for cars, trucks and aeroplanes. Scientists at the University of Indiana recently figured out how to turn seaweed into biodiesal four times faster than other biofuels. Low seaweed demand in India discourages farmers towards seaweed cultivation. To ensure that the farmers have seaweed buyers for sure we can establish a connection between farmers, poultry farms and biodiesel plants.All the three are interdependent and interconnected. Thus, establishing a connection among the three can solve the problem of lack of demand.

Insight 3:
Lack of labours and lack of knowledge in the field of seaweed cultivation is yet another cause of low seaweed cultivation in India even after its wide scope in the country.We can conduct training camps where the farmers having good knowledge of seaweed cultivation would train the novice farmers and the people in need of an occupation. This will encourage employment in seaweed farming and ensure that the country uses the untapped seaweed wealth to its full potential.
