B. orientalis, fairy shrimp, is often among the most conspicuous invertebrates inhabiting temporary aquatic habitats with a typical variation in environmental conditions. Its life history characteristics and biochemical composition were studied under four different photoperiodic regimes (24L:0D, 0L:24D, 16L:8D, and 12L:12D). The significantly highest cumulative and initial hatching rates (48 h) were obtained at 24L:0D (p < 0.05). Cultivating the larvae under different photoperiods did not significantly affect specific growth rate (SGR) (p > 0.05). However, higher final total body length and daily growth rate were recorded under constant darkness. Higher lipid content was found at 24L:0D to the extent that it was more than two times higher than that at 16L:8D and 12L:12D (p < 0.05). There was also a remarkable increase in body crude protein content at 24L:0D (p < 0.05). Body fatty-acid profiles of the fairy shrimps were also affected by culture condition (p < 0.05). Extension of lighting period resulted in a subtle increase in body contents of arginine, lysine, histidine, isoleucine, leucine, valine, methionine, and phenylalanine, especially in the group kept under a 16L:8D regime. The highest and lowest digestive enzyme activity was observed at 0L:24D and 24L:0D, respectively (p < 0.05). In contrast, the highest and lowest soluble protein content was recorded at 24L:0D and 0L:24D, respectively (p < 0.05). Similarly, antioxidant status was significantly higher at 0L:24D (p < 0.05). In conclusion, a 16L:8D light–dark cycle might be an optimal condition in terms of growth performance and physio-biochemical characteristics. These findings could be helpful in optimizing the rearing conditions for upscaling B. orientalis production.

Abstract This study investigated the effects on survival, growth performance and water quality of algae, yeast and photosynthetic bacteria as diets for larval and immature/mature Streptocephalus sirindhornae. Survival of the larvae fed with the alga Chlorella vulgaris and the photosynthetic bacterium Rhodopseudomonas faecalis for 5 days was higher than 80%, while those fed with the yeast Saccharomyces cerevisiae was 4.4%. After feeding the 6-day-old fairy shrimp until they reached 30 days of age, those fed with bacteria showed the highest survival and growth rate. Ammonia, nitrate and nitrite concentrations in the water treated with R. faecalis were the lowest. The highest ammonia concentration, the lowest dissolved oxygen, and excessive turbidity were found in the yeast treatment. Frequent water replacement could not overcome this, which resulted in the low survival rate. Utilization of photosynthetic bacteria in fairy shrimp culture is for the first time reported herein, and the disadvantages of using yeast in S. sirindhornae cultivation are discussed.
