Effect of short-term immersion of Kappaphycus alvarezii (Doty) Doty in high nitrogen on the growth, nitrogen assimilation, carrageenan quality, and occurrence of “ice-ice” disease
(Springer Verlag, 2015)
Short-term immersion of Kappaphycus alvarezii (Doty) Doty in a high-nitrogen-containing medium was tested to increase growth, improve the quality of carrageenan, and decrease “ice-ice” disease occurrence. Tank-reared ...
The seasonality and economic feasibility of cultivating Kappaphycus alvarezii in Panagatan Cays, Caluya, Antique, Philippines
(Elsevier, 2001)
Vegetative thalli of brown and green <i>Kappaphycus alvarezii</i> were cultivated in Panagatan Cays, Caluya, Antique, Philippines, over 60- and 90-day periods using hanging-long line (HL), fixed off-bottom (FB), and hanging ...
Polyculture of milkfish Chanos chanos (Forsskal) and the red seaweed Gracilariopsis bailinae (Zhang et Xia) in brackish water earthen ponds
(Wiley-Blackwell, 2004)
Growth, net production, and survival rates of milkfish cultured with Gracilariopsis bailinae at two stocking density combinations (T<sub>1</sub>– 30 fingerlings 100-m<sup>−2</sup> pond+1-kg G. bailinae 4-m<sup>−2</sup> net ...
Carpospore germination and early stages of development in Gracilaria edulis (Gmelin) Silva and Gracilaria rubra Chang et Xia (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1993)
Carpospore germination and early stages of development in Gracilaria edulis and Gracilaria rubra of the Philippines are described for the first time. Both species follow the "Dumontia type" or the immediate discal type of ...
Deep-sea farming of Kappaphycus using the multiple raft, long-line method
(Walter de Gruyter, 2002)
Farming practices of Kappaphycus seaweed planters using the multiple raft, long-line method were assessed in three major cultivation areas of Zamboanga del Sur, Mindanao. Results show that this cultivation method is ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
The effects of different stocking densities and some abiotic factors on cage culture of Gracilaria sp. (Rhodophyta, Gigartinales)
(Walter de Gruyter, 1992)
Specific growth rates (% day<sup>-1</sup>) and production rates (g m<sup>-2</sup> day<sup>-1</sup>) of Gracilaria sp. reared in net cages on a bamboo floating raft from March 1989 to February 1990 were determined at different ...
Improvised filter unit for agar extraction/filtration
(San Carlos Publications, University of San Carlos, 1993)
Agar is a high-priced phycocolloid usually extracted from red seaweeds (Rhodophyta). It has many uses in the food and pharmaceutical industry (Chapman 1970, Armisen and Galatas 1987). Worldwide production of agar has reached ...
Effects of gel depth and gel surface area on agar gel strength
(San Carlos Publications, University of San Carlos, 1993)
Agar is a high priced phycocolloid extracted from red seaweeds (Rhodophyta) called agarophytes. It is a mixture of polysaccharides whose basic monomer is galactose (Armisen and Galatas 1987). Agar has many uses in the food ...
Effect of stocking density and nutrients on the growth and agar gel of Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1995)
The effect of additional nutrients and varying stocking densities (500, 1000, and 2000 g m<sup>-2</sup>) on the growth and physical properties of Gracilariopsis bailinae was determined. Growth was significantly higher (L ...
