Title:	Growth rate of Pseudocalanus spp. as a function of food concentration, body weight and temperature
Authors:	Dzierzbicka-Głowacka Lidia Zieliński Andrzej
Abstract:	This paper does not report the results of original research; it is an analysis of data from the literature. The aim of this project was to develop quantitative expressions to describe the effects of food concentration, temperature and body weight on the growth rate of copepodid stages of Pseudocalanus spp. Calculations were done for two geographically separate populations of Pseudocalanus â one from Puget Sound (Washington, USA) and the other from the southern North Sea - based on experimental data from the literature. The relationships between the growth rate of Pseudocalanus from Puget Sound and temperatures in the range of 8 - 15.5^oC, food concentration and body weights ranging from 1.5 to 10 ug d.w. (case 1) and 0.51 to 3.7 ugC (case 2) were determined, as were those for Pseudocalanus from the southern North Sea at a high food concentration and at temperatures ranging from 4 - 15^oC. The results demonstrate that the maximum growth rate decreased as temperature fell and that it become less dependent on temperature at higher body weights. The critical food concentration for growth increased with body size proportionally more at high than at low temperatures. Slight differences in growth rate were also detected between the two species of Pseudocalanus.
