Growth of Gracilaria sp. in the laboratory
Hydrobiologia, 1987Gracilaria species are important agarophytes along the coast of Chile. About 80000 tonnes (air dried) are exported annually as raw material, producing an income of US$ 8 x 106 (Servicio Nacional de Pesca, 1984). In spite of the economic importance of Gracilaria, few aspects of its biology have been investigated. Observations on morphology, taxonomy and

SUMMARY Japanese populations of the red alga Gracilaria blodgettii Harvey (Gracilariaceae, Gracilariales) were reinvesti-gated by morphological and cultural studies. Plants of populations growing on the Pacific coast of central Japan (Shizuoka and Chiba Prefectures) produce deep pot-shaped, Verrucosa-type spermatangial conceptacles and are entirely ...

Culture of Gracilaria sp. in outdoor tanks: productivity
Hydrobiologia, 1987Gracilaria is one of the main commercial seaweeds exploited along the Chilean coast. In 1983, 10.6 x 105 tonnes of this alga were exported as raw material, returning a revenue of 7 x 106 dollars (Servicio Nacional de Pesca, 1983). Gracilaria has been planted on sandy bottoms in protected bays with normally calm water using uncomplicated methods.

Journal of the Marine Biological Association of the United Kingdom, 1977
Two species of Gracilaria, G. foliifera (Forsk.) Børg. and G. verrucosa (Huds.) Papenf., have been recorded from the Maritime provinces of Canada (South & Cardinal, 1970), although in recent years only G. foliifera var. foliifera is listed (South, 1976). These species are also known from the British Isles (Parke & Dixon, 1976).

Antonie van Leeuwenhoek, 2015
A Gram-negative, strictly aerobic, beige-pigmented, non-motile, rod-shaped bacterial strain designated N5DB13-4(T) was isolated from the red alga Gracilaria vermiculophylla (Rhodophyta) collected at Sodegaura Beach, Chiba, Japan. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the novel isolate is affiliated with the family ...

Importance of coalescent development of Gracilaria sp. tetraspores
Phycological Research, 2016SUMMARYGracilaria spp. are dominant macroalgae inhabiting the intertidal zone and are exposed to constant wave action and currents. In wild Gracilaria populations, fronds tend to occur in clusters, being grouped close to one another on the shore. It is rare to find thalli growing individually, but the reason for such a clustering development is unknown.

Utilizzazione di reflui di acquacoltura per l'allevamento di Gracilaria sp.
1996Gracilaria is one of the main commercial seaweeds, cultivated in many countries to produce agar, an industrial colloid. By growing this alga on the wastewater of an aquaculture plant, pollution may be reduced and alga production costs lowered. Preliminary results of cultures of G.

Experimental tank cultivation of Gracilaria sp. (Gracilariales, Rhodophyta) in Ecuador
Hydrobiologia, 1996This paper describes experiments to grow a local and still unidentified species of Gracilaria in shrimp hatcheries in Ecuador. The experiments used outdoor tanks of 1 and 18 m3 capacity, with continuous aeration and water renewal every two and five days, respectively.

ANALISIS HISTOLOGI SEL Gracilaria sp. PADA MEDIA TERCEMAR MERKURI (Hg)
Jurnal Perikanan UnramGracilaria sp. memiliki sifat filter feeder yang memiliki kemampuan dalam menyaring atau mengakumulasi segala unsur yang ada di lingkungannya. Kemampuan tersebut tentunya memungkinkan makroalga dapat mengadsorbsi logam berat merkuri (Hg) yang ada di lingkungan perairan. Oleh karena itu, untuk mengetahui respon sel Gracilaria sp.
