    • Fecundity of sprat from the Norwegian coast 

      Torstensen, Else (ICES CM Documents;1985/H:56, Working paper, 1985)

    • Growth and maturity of sprat in Norwegian coastal waters 

      Torstensen, Else (ICES CM documents, Working paper, 1998)
      Data on length, age and maturity were analysed to study the growth and spawning of sprat in fjords on the Norwegian West Coast. The data were sampled in 4 fjord Areas in November 1993-1997 (for mean length and weight-at-age) ...
