Neocaridina heteropoda heteropoda, also known as "red cherry" shrimp, is very popular as ornamental species. This study analyzed the effect of temperature on male growth, biochemical composition and reproductive system structure. Recently differentiated males were exposed during 90 days to one of the following temperatures: 24°, 28° and 32°C. Males were maintained in plastic containers with continuous aeration and Java moss. Results showed higher final weight and total lipid content in males exposed to 24°C (12.67 ug/mg versus 9,48 and 8,5 ug/mg for 28°C and 32°C, respectively) with no differences in protein content among treatments (~ 16 ug/mg). This may reflect a better efficiency in using energy reserves. No effect of temperature was detected on the histological structure of testes and vasa deferentia so it would be expected no effect of this temperature range on reproductive function.
