CMFRI provides inputs on seaweed farming

Seaweed cultivation is perceived as an environmentally-benign types of mariculture activity. A feasibility study conducted in the seawater inundated areas in South Andamans by a team of CMFRI scientists has revealed that these regions are highly prospective for the seaweed farming, it said. 

As part of transferring the technology, the CMFRI provided practical training on methods of the farming practices to officials of the Department of Fisheries in Andaman. Training on fabrication of floating rafts with bamboo, tying of seed material (seaweed fragments) in the ropes, tying of seeded ropes in the bamboo rafts and positioning them in the sea were given to the participants.

The CMFRI provided technical inputs on monoline culture method of the seaweed to the officials of the Fisheries Department in Andaman. The expert group from the CMFRI also educated the officials on seaweed distribution and diversity in the Palk Bay and Gulf of Mannar regions and seaweed products, besides giving training on wild collection of seaweed and identification of commercially important seaweed species. 

A K Abdul Nazar, Scientist-in-Charge of Mandapam Regional Centre of CMFRI and Johnson B, Scientist at the Centre coordinated the training programme. The seaweed farming venture, to be launched off the Andaman coast, will definitely help meet the growing demand in the industry, said Nazar. “Seaweeds are renewable source of food, energy, chemicals and medicines and valuable source of raw material for industries like health, food, medicines, pharmaceuticals, textiles, fertilizers, animal feed, etc.”

Chemicals from brown seaweeds such as alginic acid, mannitol, laminarin, fucoidin and iodine have been extracted successfully on a commercial basis,” he said. 

CMFRI had developed an anti-diabetic nutraceutical, CadalminTM Antidiabetic extract (ADe) from seaweeds. The product is effective to combat type-2 diabetes. It also developed another medicinal product, Green Algal extract (CadalminTM GAe), from seaweeds to combat inflammatory pain and arthritis.
