Nitrogen excretion in Streptocephalus Dichotomus Baird (Crustacea: Anostraca)

  • R. Bernice


The total nitrogen excreted by Streptocephalus dichotomus is 1.5177 mg/g/day for males and 1.3875 mg/g/day for females at 30°C.

The main excretory product of S. dichotomus is ammonia (75.3%). The rate of excretion of ammonia increased with increase in temperature up to 30°C and at 33°C it decreased.

Analyses of covariance revealed that the ‘F’ ratios are not significant in the case of rate of total nitrogen excretion between the two sexes at 30°C and in the case of rate of ammonia excretion between the two sexes or when comparison is made within the sexes at the different temperatures between 20° and 30°C.
