“…In this study, the super-small type or ss-type rotifer Brachionus rotundiformis was used, which has a size range of 90-160 µm; such a size range is likely too small for the C. retusa larvae to either capture or despite being consumed, energy budget was poor so that could not sustain successful development to the next stage. Similarly, in southern rock lobster, Jasus edwardsii, phyllosoma larvae showed prolonged development when live prey was too small (Ritar et al, 2003). Indeed, the relationship between prey size and larvae is a critical factor to consider in larval feeding, the disproportion of the size between food particles and larval feeding appendages may incapacitate the larvae to effectively capture the prey or despite larvae can capture and consumed the prey, they would eventually die due to unable to acquire a sufficient energy to sustain normal development (Guarizo et al, 2020;Ritar et al, 2003;Ruscoe et al, 2004;Sui et al, 2008).…”

Decorator crab Camposcia retusa is a popular marine ornamental species; however, it has never been bred previously. To establish a feeding regime for C. retusa larvae, which include two zoeal and a megalopal stage, three experiments were conducted. In all experiments, ≥60% of unfed 1st zoeal (Z1) larvae survived to the next stage, combined with the orange guts observed in larvae fed Artemia, suggesting Z1 larvae are facultative lecithotrophic. Experiment 1 evaluated the suitability of ss‐type rotifer Brachionus rotundiformis as prey. Z1 larvae were fed rotifer at a density from 0 to 90 ind./ml. There was no significant difference in Z1 survival among treatments (56.7–68.3%, p > 0.05); therefore, ss‐type rotifer is considered an unsuitable prey for the larvae. Experiment 2 examined the suitability and optimal density of Artemia nauplii, and co‐feeding copepod Pavocalanus crassirostris with Artemia, for larval rearing. The larvae fed 10 Artemia/ml had the highest survival to megalopae (91.3 ± 3.1%, p < 0.05). However, high mortality occurred in megalopae, resulting in poor survival to the 1st crab stage (1.3%–12.5%) in all treatments (p > 0.05). Meanwhile, co‐feeding copepods with Artemia showed significantly inferior survival and development to megalopae when compared to that of 10 Artemia/ml treatment. Experiment 3 evaluated the effects of Artemia enrichment on larval performance. The results suggested that Artemia enrichment did not improve larval survival or development. Based on our results, Artemia nauplii fed at 10 ind./ml throughout larval development appears to be appropriate for C. retusa.
