Abstract

M. Khailov The Institute ofthe Biology ofthe Southern Seas ofthe Ukrainian Academy of Sciences, Sevastopol, USSR. (Received 10. !. 76) For Ascophyllum nodosum, Fucus vesiculosus, Fucus inflatus and Rhodymenia palmata in the Barents Sea a quantitative description isgiven of the relationship between length (L) and weight (W) ofthe thallus, and for/4. nodosum also between weight (W) and age (7"). The weight of the thallus has also been related to the intensity of two physiological functions - photosynthesis (/*,·) and the consumption of organic substances (P0) dissolved in the water.
