Fig. 5. Correlative cost of protein synthesis in embryos (open circles), unfed larvae (open squares) and fed larvae (filled squares) of L. pictus. Cost of protein synthesis was calculated from the slope of the relationship between protein synthesis and metabolic rate. The broken line is the regression of metabolic rate and protein synthesis for all stages of development studied (embryos, unfed and fed larvae). Slope of regression=8.41±0.49 J mg^-1 protein; r²=0.95; N=17). Solid line is regression for fed larvae alone=7.69±1.36 J mg^-1 protein; r²=0.91; N=5).
