Abstract
This
paper reports on a new method of natural seeding which make attach
embryos released from the natural Sargassum fusiforme
community to a nori culture net (as a seeding apparatus) set near a
wild S. fusiforme bed. A natural seeding experiment
was carried out in the Awata Fishing Port, Eastern Seto Inland Sea,
Western Japan and total amount of 7,680 juveniles were obtained from a
nori culture net of 4.8 m2. The S. fusiforme
was cultured in the sea off the port for 152 days, and conse- quently
1.2 kg (wet weight) of S. fusiforme per 1 m of the
culture rope were harvested. Application of nori culture nets is
a practical method in natural seeding and raising seedlings of S.
fusiforme due to its ease of handling, low cost and
labor.
