The aquaculture of mangrove crabs Scylla spp. has increased over the years, primarily due to the need to meet the high consumer demand and to reduce wild harvest. The price of the crab corresponds to the crab quality; hence, the health and nutrition of the early stages of crabs in culture are intensively studied for profit maximization. In this study, Zoea (Z1) were obtained during a spawning episode and were fed with SELCO®-enriched and non-enriched rotifers. The stocking density of the zoea were recorded every two days whereas the growth and development of zoea individuals were monitored daily. In midst of the study, an incidental occurrence of Vorticella parasitism occurred in both treatments. Although an increase in zoea mortality was observed over the days, the stocking density of parasitized zoea fed with both treatments were significantly different – lower mortality was observed in parasitized zoea fed with SELCO®-enriched rotifers. In addition, Z1 fed with SELCO®-enriched rotifers managed to metamorphose into Z2 more readily; the stocking density, however, crashed two days later after Z1 that was fed with non-enriched rotifers. In another study, crablets (C1) were fed with formulated feed and seafood. The carapace length and weight of crablets were significantly different – crablets fed with formulated feed were larger and heavier, suggesting that formulated feed provided more nutrients than seafood. Results observed from these two studies inferred the benefits of bioenrichment and the importance of nutrient availability for the optimal growth and development in the early stages of crabs.
