The eels raised in this operation were judged to be of good quality for eating, with soft skin and tender flesh. Fishermen in the New Brunswick area were pleased with the project because it tended to control the eel population in the rivers, thereby reducing eel predation on salmon and trout. However, trials suggested that the station was not economical; in fact, a recent assessment of the potential for eel aquaculture rates this species as very low. Current Status of Aquaculture Species whose culture can now be pursued vigorously on a commercial scale include chinook, coho, and sockeye salmon, rainbow and brook trout, and Atlantic and Pacific oysters.
Aerial spraying of aqueous solutions of inorganic nitrogen and phosphorus can increase production of young sockeye salmon in nutrient-deficient lakes. Nutrient enrichment increases phyto- and zooplankton production, thus providing more food during the lake-dwelling period of the sockeye. In British Columbia, smolts leaving most fertilized lakes were larger than in pretreatment condition, and observed marine survival of returning adults surpasses anticipated levels. Salmon farming in British Columbia took a giant leap forward during 19859, going from approximately 107 mt to about 13,600 mt.
