| Zusammenfassung |
| The paper presents an empirical model describing the growth rate and stage duration of
specific size-classes of Temora longicornis. The quantitative expressions describing the effect
of food concentration on the above parameters were developed. The stage duration of
Temora longicornis was calculated on the basis of experimental data. According to
these data, the growth rates of Temora longicornis were obtained by the numerical
solution of polynomials of the appropriate degrees. The polynomials were described
by:
( )
(Wi + Wi gmax) 1+ gmax + g2max + ...+ gnmax +gdmax = Wi+1
where Wi is the mean body weight of specific size-classes, D = n + d is the stage
duration
and Dis a known quantity and gmax is the growth rate. Empirical model computed here
may be used with good precision in mathematical models of pelagic communities. |
