 note = {Sediment flux in coastal culture farms was observed in order to estimate an environmental load resulting from fish feeding. Observations were made 63 times, between October 1977 and February 1980, in the farms located around the Fisheries Research Laboratory of Kagoshima
University.
The sediments were collected from 3 stations: St. 1 in a sea bream farm, St. 2 in a yellowtail farm,
and St. 3 in a non-culture area. Water depth in the St. 1, 2, and 3 were: 8 to 12 m, 14
to 16 m, and 12 to 13 m, respectively. Polyethylene columns, 5 liters capacity with 17 cm
opening, were set on the sea bottom at each station, and renewed every 4-days during the
culture seasons. The samples were filtered after collection, and dried at 60°C for 5 days.
The food quantity and quality were noted every day in each farm.
Average daily amounts of sediments in St. 1, 2, and 3 were calculated to be: 33.8, 23.0, and 14.6 g/m^<2>, respectively. The sedimentations were related to the amount of foods supplied,
and to water depth. Some diffusion of biodeposits was observed in a deeper farm. The
type of food supplied also affected the amount of sediment flux. The amounts of sediments
ranged from 4.1 to 5.9 g/m^<2> when the fish were fed daily on 1202 kg of fresh anchovies, but such
amounts increased about 4 times, 17.0 to 21.6 g/m^<2>, when 1247 kg of frozen mackerel were
supplied.},
