5203 |a"Declining salmonid stocks in the Indian River prompted enhancement activities in the area during the 1970's. Nine separate sites in the Indian River watershed were drilled and tested for water quality between 1972 and 1982. All groundwater samples showed excessively low buffering capacity and hardness, slightly acidic water and low mineral content. The Indian River surface water showed similar characteristics. In addition, unacceptably high levels of iron and zinc occurred in some of the wells. To test the suitability of well No. 2 groundwater for culture of chinook, approximately 250,000 chinook eggs were transported from the Capilano hatchery to the Indian River pilot hatchery during November 1979. In June 1980, approximately 194,300 chinook smolts each weighing approximately 3 - 6 g were released into the Indian River; of these fry, 102,512 were tagged with code 02-18-39. Although egg-to-ponding survival was 91% and egg-to-release survival was 78%, rearing mortality could be related to inferior water quality and would be likely to be more severe under production fish culture conditions. Wells No. 7b and No. 9 may be most suited for fish culture purposes, but would. require treatment in the form of aeration and mineral enrichment. These studies indicate that water quality is marginal for fish culture purposes in the Indian River watershed"--Abstract, page v.
