摘要：

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 in natural drainage canals and ponds. Initial harvests are made 15-60 days after planting. Higher production [7-14 t (dry) ha-1 year-1] are obtained from cultures in canals than in ponds [3-4 t (dry) ha-1 year-1]. The net income derived from culture in ponds is estimated at P698BAR/crop or P6313BAR/year (US$234/year). A higher net income of P4936BAR/crop or P41 766BAR/year (US$1547/year) was generated from Gracilaria farming in canals. Returns on investment (ROI) from farming in ponds and canals are 39% and 908%, respectively. Payback period is 2 months in canal farming and 1.8 years in pond farming.
