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
4. Biomass for fuel
6.Integrated aquaculture-source of raw material for agar industry
7.Wastewater treatment-remove heavy metals from water
