Bottom Line: These results suggest growth was delayed at 24 °C, but only for 30 days after hatching.During the growth period, shrimps reached sexual maturity and mated, with the highest proportion of ovigerous females occurring at 28 °C.All the females that matured and mated at 32 °C lost their eggs, indicating a potentially stressful effect of high temperature on ovarian maturation.

ABSTRACT
The effect of water temperature on biochemical composition, growth and reproduction of the ornamental shrimp, Neocaridina heteropoda heteropoda, was investigated to determine the optimum temperature for its culture. The effect of embryo incubation temperature on the subsequent performance of juveniles was also evaluated. Ovigerous females and recently hatched juveniles (JI) were maintained during egg incubation and for a 90-day period, respectively, at three temperatures (24, 28 and 32 °C). Incubation period increased with decreasing water temperature, but the number and size of JI were similar among treatments. At day 30 of the 90-day period, body weight and growth increment (GI) at 24 °C were lower than those at 28 and 32 °C. On subsequent days, GI at 24 °C exceeded that at 28 and 32 °C, leading to a similar body weight among treatments. These results suggest growth was delayed at 24 °C, but only for 30 days after hatching. The lipid concentration tended to be lowest, intermediate and highest at 28, 32 and 24 °C, respectively, possibly as a consequence of the metabolic processes involved in growth and ovarian maturation. Protein and glycogen concentrations were similar among treatments. Both the growth trajectory and biochemical composition of shrimps were affected by the temperature experienced during the 90-day growth period independently of the embryo incubation temperature. During the growth period, shrimps reached sexual maturity and mated, with the highest proportion of ovigerous females occurring at 28 °C. All the females that matured and mated at 32 °C lost their eggs, indicating a potentially stressful effect of high temperature on ovarian maturation. Based on high survival and good growth performance of shrimps at the three temperatures tested over the 90-day period it is concluded that N. heteropoda heteropoda is tolerant to a wide range of water temperatures, with 28 °C being the optimum temperature for its culture.

Body weight (mean±SE) of shrimps during the Growth period of Experiment 1 (A) and Experiment 2 (B).Neocaridina heteropoda heteropoda juveniles were reared at three different water temperatures (24, 28 or 32°C) over a 90-day period, and the body weight was recorded every 30 days. Different letters at days 30 and 60 indicate statistically significant differences among treatments (P < 0.05); the letter “a” at day 90 indicates the absence of statistically significant differences among treatments (P > 0.05). In both experiments, body weight of shrimps maintained at 24°C was lower than that of shrimps maintained at 28°C at days 30 and 60, but this difference was no longer significant at day 90.

Mentions: At days 30 and 60 of the Growth period of both experiments body weight was lowest, highest and intermediate (P < 0.05) in juveniles maintained at 24, 28 and 32°C, respectively. However, at day 90 this variable was similar (P > 0.05) among treatments (Fig. 3). The growth increment (GI) was significantly lower (P < 0.05) at 24°C than at the other temperatures tested over the first 30 days. This was completely reversed during the following 60 days, with the GI of shrimps at 24°C exceeding that of shrimps at 28 and 32°C (P < 0.05). At the end of the Growth period, GI was lowest, intermediate and highest (P < 0.05) at 28, 32 and 24°C, respectively (Fig. 4).
