Economics of cultivating Kappaphycus alvarezii using the fixed-bottom line and hanging-long line methods in Panagatan Cays, Caluya, Antique, Philippines
(Springer Verlag, 1996)
A socio-economic survey was conducted among the Kappaphycus alvarezii planters of Panagatan Cay, Caluya, Antique, Philippines to determine some social information, farming practices and cost and returns of farming the ...
Growth of Gracilaria sp. (Gracilariales, Rhodophyta) in brackishwater ponds at different stocking densities.
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The specific growth rate (% per day) and net production rate (g per m<sup>2</sup> per day) of Gracilaria sp. cultivated in net cages in a brackishwater pond were determined at different stocking densities (200, 250, 300 ...
Growth rate, yield and economics of Gracilariopsis bailinae (Gracilariales, Rhodophyta) using fixed bottom long-line method
(Science and Technology Information Institute, 1997)
Vegetative thalli of Gracilariopsis bailinae weighing 10 g each were tied to a 5-m monofilament line with plastic strips and laid horizontally on the substrate and were observed to grow at 30 d interval for 9 months. The ...
Vertical rope cultivation of Gracilaria (Rhodophyta) using vegetative fragments
(Walter de Gruyter, 1990)
Preliminary field culture of Gracilaria using vegetative fragments inserted between braids of ropes suspended vertically inside a floating cage was undertaken to assess the daily growth rate and monthly yield as influenced ...
Gracilaria (Rhodophyta) farming in Panay, Western Visayas, Philippines
(Elsevier, 1992)
Interviews were conducted among eight Gracilaria growers in Panay, Western Visayas, Philippines from March to July (1990) using a structured questionnaire. The "rice planting" method was employed by farmers growing seaweeds ...
Carrageenan properties and proximate composition of three morphotypes of Kappaphycus alvarezii Doty (Gigartinales, Rhodophyta) grown at two depths
(Walter de Gruyter, 1995)
Three morphotypes (brown, green and red) of Kappaphycus alvarezii grown at two depths were evaluated for carrageenan properties and proximate composition. The green morphotype was significantly different from the brown and ...
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 ...
Agar yield, gel strength and sulfate content in Gracilariopsis heteroclada farmed in brackishwater canals
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)
This paper aimed at determining the optimum NaOH pretreatment strength and duration and the monthly variations in gel strength, agar yield and sulfate content of agar from Gracilariopsis heteroclada (Zhang et Xia) farmed ...
Cage culture of Kappaphycus alvarezii var. tambalang (Gigartinales, Rhodophyceae)
(Springer Verlag, 1992)
Kappaphycus alvarezii var. tambalang was cultured in a 3 × 3 m bamboo raft installed inside a 4 × 4 m floating net cage of Lates calcarifer (sea bass) broodstock at SEAFDEC Sub-station Igang, Guimaras, Philippines, from ...
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 ...
