“…The growth performance of the larvae was not affected by the systems used, where the ammonia level also did not show significant different among the system (Ong et al, 2019). The biofloc water was identified provide natural food sources through the floc particle that comes from the bacteria, protozoa, phytoplankton, zooplankton, nematodes, ciliates and rotifer as diets (Manan et al, 2017) such as the compositions of live feed found in the green water system (Ong et al, 2019).

“…Research conducted on the application of biofloc water system, green water and RAS system on the survival and growth of mud crab, Scylla paramamosain larvae from zoea to megalopa stages identified that the highest survival and good quality of larvae reached to megalopa stage was from the green water system as compared to other system (Ong et al, 2019).

Biofloc technology is instrumental in improving growth performance and yield in shellfish aquaculture, while leading to enhanced water quality through maintaining the nutrients level within a safe range. More specifically, toxic nitrogenous wastes are converted into beneficial microbial biomass known as “biofloc”, contributing to improve shellfish immune system. Among the various parameters affecting the efficiency of the process is the carbon source and C:N ratio. In light of these, the present work critically reviews the effects of biofloc systems on growth performance, immunity and diseases resistance in shellfish production. Moreover, it scrutinizes the microbial diversity and nutritional composition of biofloc. Then, the application of the technology in various shellfish cultures, including shrimp, freshwater prawn, crabs, crayfish, clam, and oyster, are presented. Overall, biofloc systems contribute to enhanced shellfish survival rate to the highest value of 96-100% for marine shrimp, 95-99% for freshwater prawn, 70-83% for crayfish, 83-100% for oyster, Crassostrea sp. and up to 2% for mud crabs larvae through substantially reducing the ammonia level in the culture (summarized in table 1- table 5). Finally, the main challenges in utilizing biofloc systems, i.e., suitable aeration and mixing and microbial mechanisms involved are also explained to shed light on future research directions in the field.

“…Water quality parameters can play a vital role in regard to all aquaculture practices especially to maintain the healthy larvae (Gunarto and Sulaeman 2017). Suitable water quality variables ensure higher growth rate, survivability and production in mud crab larvae rearing (Ong et al 2019). In the present study, the temperature of the rearing tank varied within the range of 29.1~31.0ºC.…”

Orange mud crab (Scylla olivacea) is an important aquaculture species in Southeast Asian countries, especially in the Southwest costal region of Bangladesh. Due to unavailability of hatchery produced seeds the farming of S. olivacea in exclusively depends on the wild for small juveniles resulting in exploitation of this species in Bangladesh. The development of proper hatchery techniques considering better understandings related to larval development are needed to increase the survival and growth rate of S. olivacea in hatchery conditions. Therefore, this study aimed to optimize the water treatment strategy for the upgrading of water quality, minimizing mortality and shortening the metamorphosis duration during larval rearing of mud crab. Newly hatched larvae were reared in three different rearing conditions where the water was treated with both prebiotic (Super-TCT-Biotic, 5 ppm) and probiotics (Fish probiotic, 0.5 ppm) in treatment-1 (T1) but only prophylaxis (mixure of 0.025 ppm Teflan and 0.3 ppm Furazolidone) in treatment-2 (T2). In treatment-3 (T3), prebiotic (5 ppm) and probiotics (0.5 ppm) were combinedly used during first 10 days and prophylaxis (0.3 ppm) was also used from day 14 to day 25. The stocking density was maintained as 50 zoea.L-1 and rotifer, liquid rotifer, enriched Artemia and liquid Artemia were used as feed for the larval growth. The findings revealed that hydrological parameters viz., temperature, salinity, pH, dissolved oxygen and ammonia in all the treatments were similar and found within the acceptable ranges for mud crab larvae rearing. The value of larval stage index (LSI) was found significantly higher (p<0.05) on 21st day of rearing in T3 (6.87±0.06) than T1 (6.74±0.04) and T2 (6.61±0.07). Between, zoea1 and crablet phase, the significantly higher survival rate was observed in T3 (7.00±1.00) than T1 (5.00±0.00) and T2 (4.00±1.00). The result of the present study suggested that combined water treatment with prebiotic, probiotic and prophylaxis can shorten the metamorphosis period and enhance the survival rate of S. olivacea.
