Results of accelerated rearing of Atlantic salmon, Salmo salar L., smolts by use of warm waste water
The results of rearing salmon smolts, using warm water in winter time, are presented. Fishes weighing 25–50 g were released in spring time at the age of about 1 year, while smaller fishes were left to grow in ponds for release at age 2 years. As a result of warm‐water wintering of fingerlings, the y...

| Summary: | The results of rearing salmon smolts, using warm water in winter time, are presented. Fishes weighing 25–50 g were released in spring time at the age of about 1 year, while smaller fishes were left to grow in ponds for release at age 2 years. As a result of warm‐water wintering of fingerlings, the yield to the fishery was at least doubled, while there was no decrease in fish size, nor in gamete quality. Three thousand to 5000 spawners entered the Narova River (Baltic Sea) per annum and the trend is to exceed these totals. |
