Rearing Pacific Salmon In Saltwater Ponds Fertilized With Domestic Wastewater : September 1974-November 1975

Two 0.15-hectare ponds (North and South Ponds) using mixtures of treated domestic wastewater and seawater were used to rear juvenile salmonids without supplemental feeding. Ponds are located within the periphery of an oxidation pond located on the north arm of Humboldt Bay, Humboldt County, Arcata, California. Forced air and surface spray systems of pond aeration and mixing of pond waters were employed to maintain water quality. Rearing experiments occurred in three seasons; October 1974 - January 1975 (Experiment IX) ; February - May 1975 (Experiment X), and May - November 1975 (Experiment XI).
