Bartel R., 1985. Growth of tagged rainbow trout (Salmo gairdneri Rich.) released to the Baltic Sea. Acta Ichthyol. Piscat. 15 (Suppl.): 51-63.
On the basis of 2436 tag returns (10.3%) from 23624 one- and two-year old rainbow trout released into the Gulf of Gdańsk and the Vistula mouth, calculations were made of the fish growth. After the first year rainbow trout released at the age of one year attained 43.8 cm and 1048.8 g, while those released at the age of two years reached 48.7 cm and 1408.7 g. After the second year the respective values amounted to 59.8 cm and 2631.6 g, and 62.4 cm and 3251 g.
