Seasonal variations in the energy density of fishes in the North Sea
The energy density (E-D, kJ g(-1) wet mass) of saithe Pollachius virens, haddock Meleanogrammus aeglefinus, whiting Merlangius merlangus, Norway pout Trisopterus esmarki, herring Clupea harengus, sprat Sprattus sprattus, sandeel Ammodytes marinus and pearlsides Maurolicus Muelleri, from the North Sea, increased with total length, L-T.
However, there was not always a significant (P >0(.)05) linear relationship between L-T and E-D. Seasonal differences in E-D were obvious in mature fish, while geographical differences were insignificant. For all species there was a highly significant correlation (P
