Gracilaria is a genus of red algae ( Rhodophyta) notable for its economic importance as an agarophyte, as well as its use as a food for humans and various species of shellfish. Various species within the genus are cultivated among Asia, South America, Africa and Oceania. Gracilaria bursa-pastoris and Gracilaria multipartita have long been.
Gracilaria is a group of warm water seaweeds. There are more than one hundred species in the world, some of which have very important economic value. Gracilaria is used as food and in the preparation of food products.

The genus Gracilaria was established by Greville in 1830 and is the third largest genus in the red algal group with over 150 species worldwide. Nearly 28 species of Gracilaria have been reported from the Indian coast (Sahoo et al., 2001). Gracilaria can grow in a wide range of salinities from 5 to 34 ppt, which makes it a common seaweed of brackish water, mangrove swamps, and the sea.
Gracilaria parvispora has solid, commonly compressed branches, 1 - 4 mm in diameter, with long narrow, pointed tips. The plant grows tall, to 30 cm or more, with a single dominant axis, 0.8 - 3.5 mm diameter, usually with 3 orders of branching or, if more, the last order is short, slender and spine.
Gracilaria salicornia is one of the most successful invasive algae on reef flats. It appears competitively linked with the native G. coronipfolia and G. parvispora, but its mat form allows for a more robust growth rate, and it is hardier than the natives.

Found in most seas Gracilaria tikvahiae (Graceful Redweed, above) in particular is common around the water of where I now live, Florida. In fact, it is one of the major seaweeds — with G. confervoides, left — in the brackish lagoon called Indian River, about 50 miles east of here. Further, the Keys ship G. tikvahiae to Hawaii for covert and overt use.

Gracilaria gracilis of Lesina Lagoon is a natural marine biomass which has already been found interesting for several applications including agar, as mesoporous material and for bio-oils production. The results of this study highlight that this marine biomass seems to be also a promising source of R-phycoerythrin if it is harvested in winter time. In the same season, the red seaweed also.

Human uses: The Gracilaria species are a major source of food-grade agar. The seaweed is both harvested from the wild and farmed for commercial applications. On farms, they are grown on ropes. A wide range of Gracilaria species have commercial uses. About 30,000 tons of Gracilaria species.

A beautiful species of Gracilaria featuring rigid, flame shaped branches that form a tight symmetrical bush. It is lightly calcified so the addition of calcium is recommended. In shallow water it is often found in very large clumps covered in colonial tunicates or encrusted with epiphytic bryozoans. The coloration varies between deep crimson.
