Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. II. Seasonal variations in the agar quality of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)
Three species of agarophytes (Gracilaria changii, G. manilaensis and Gracilariopsis bailinae) collected along the mud flats of Iloilo were investigated to determine the monthly variation in agar yield (%), gel strength (g ...
Acceptability of territorial use rights in fisheries: towards community-based management of small-scale fisheries in the Philippines
(Elsevier, 1992)
The granting of territorial use rights in fisheries (TURFs) to fisherfolk associations, similar to that practiced in Japan, is recommended as a management tool for small-scale fisheries in the Philippines. This study, ...
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 ...
A combined upflow and fluidized sand filter for recirculating systems
(Society of Aquaculture Engineers of the Philippines, Inc., 1999)
The process required and options for water treatment in recirculating systems have been clearly identified. The four most critical processes are: (1) solids removal, to take out fecal waste, uneaten feed, excess bacterial ...
Induction of oocyte maturation and ovulation in the freshwater Asian catfish, Clarias macrocephalus by LHRHa and pimozide
(Blackwell Publishing, 1992)
Three experiments were conducted to determine the effects of a simultaneous injection of varying doses of luteinizing hormone-releasing hormone analogue (LHRHa; 0.005–0.10 μg)/body weight (BW) in combination with a fixed ...
Tilapia cage culture and the dissolved oxygen trends in Sampaloc Lake, the Philippines
(Springer Verlag, 1993)
The 28-hectare tilapia cage culture that occupied the 104-hectare Sampaloc Lake, a crater lake, shifted to intensive method in 1986 when tilapia growth slowed done at the beginning of 1982. Thus, commercial feeds became ...
Biomass and reproductive states of Gracilaria heteroclada Zhang et Xia collected from Jaro, central Philippines
(Walter de Gruyter, 1996)
Biomass production and reproductive states were investigated to determine the abundance of Gracilaria heteroclada Zhang et Xia at Jaro, central Philippines from March 1990 to February 1991. Biomass of Gracilaria heteroclada ...
Participation of women in oyster and mussel farming in Western Visayas, Philippines
(Blackwell Publishing, 1995)
This paper provides baseline information on the involvement of women in small-scale coastal aquaculture such as the farming of slipper oyster, Crassostrea iredalei (Faustino 1933), and green mussel, Perna viridis (Linnaeus ...
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. I. Seasonal variations in the biomass of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)
Monthly biomass (g dwt m<sup>-2</sup>) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii ...
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 ...
