“…Further studies related to the optimal density of the M per unit area need to be carried out in the future. The stocking of M with densities of 10, 20 and 30 ind/m 2 in net cages within earthen ponds was shown to attain an average 50.5% survival rate [27] while the rearing of M in an aquarium with a density of 133 ind/m 2 had a survival rate between 11.7-31.7% on different dietary treatments [19]. Beside the stocking density, another factor that needs to be considered in determining the stocking density of M is the optimal water depth that can be used during the maintenance process for water efficiency.…”

“…Artemia is often used as the main feed during the maintenance of M to crablet stages with additional dried shrimp, dried mud worms, prawn/shrimp meat, fish meat or artificial feed (shrimp larvae feed) being added as high as a 1-5 mg/L concentration or greater [16,19,45,48]. Chen et al [49] clarified that M were able to capture prey whose sizes ranged from nauplii up to small adult Artemia.…”

“…The impact on wild populations could be lessened if sufficient support was received from the aquaculture sector in the form of seed supply from hatcheries [2,6,7]. In addition, mud crab grow-out and fattening activities incorporated within the mangrove area-known as silvo-fishery techniques [8][9][10], culture in earthen ponds [11,12] or in concrete ponds [13] and grow-out activity in indoor conditions [14,15]-could all contribute to the hatchery replacement of a wild catch. However, mud crab hatchery activities continue to be constrained by low survival rates; hence, the supply of seeds is still very limited for large-scale aquaculture purposes [2,16].…”

“…Mud crab hatcheries typically involve the maintenance of larvae to crablet size (>5 mm) before being marketed to farmers [12,18]. The maintenance of mud crab larvae in the hatchery has three stages: the Zoea 1 (Z1) to Zoea 5 (Z5) larvae, Z5 to Megalopa (M) and the maintenance of M to the crablet phase [19] (Figure 1). The hatchery production process of mud crab crablet takes about 30 days (starting from Z1 to Crablet 2-3 (C2-C3)) [20].…”

The nursery stages of mud crab, genus Scylla, proceed from the megalopa stage to crablet instar stages. We review the definition and several of the key stages in mud crab nursery activities. The practice of the direct stocking of megalopa into ponds is not recommended due to their sensitivity. Instead, nursery rearing is needed to grow-out mud crabs of a larger size before pond stocking. Individual nursery rearing results in a higher survival rate at the expense of growth and a more complicated maintenance process compared with communal rearing. The nursery of mud crabs can be done both indoors or outdoors with adequate shelter and feed required to obtain a good survival percentage and growth performance. Artemia nauplii are still irreplaceable as nursery feed, particularly at the megalopa stage, while the survival rate may be improved if live feed is combined with artificial feed such as microbound diet formulations. Water quality parameters, identical to those proposed in tiger shrimp cultures, can be implemented in mud crab rearing. The transportation of crablets between different locations can be done with or without water. The provision of monosex seeds from mud crab hatcheries is expected to become commonplace, increasing seed price and thus improving the income of farmers. Numerous aspects of a mud crab nursery including nutrition; feeding strategies; understanding their behaviour, i.e., cannibalism; control of environmental factors and practical rearing techniques still need further improvement.

This study attempted to explain the definition, objectives, and key stages in mud crab nursery activities. The nursery stages of Scylla spp was started from megalopa stage to several crablet instar stages or started from earlier crablet stage to several crablet stages. Direct stocking of megalopa into ponds is not recommended due to their sensitivity. Instead, nursery rearing is needed to produce mud crab of larger size before stocking. Individual nursery rearing results in higher survival rate (up to 100%), but with reduced growth rate, and a more complicated maintenance process compared with communal rearing. Nursery of mud crab can be done indoors, or outdoors, with adequate shelter and feed required to obtain good survival and growth performance. Artemia nauplii are the main, established nursery feed, particularly at megalopa stage, while survival rate may be improved if combined with artificial feed, such as micro bound diet formulations. Water quality parameters, identical to those proposed in tiger shrimp culture, can followed. Crablets may be transported to the pond location with, or without water. The provision of monosex seeds from mud crab hatcheries is expected to become more common, increasing seed price, and thus improving income of farmers. Numerous aspects of mud crab nursery, including nutrition, feeding strategies, understanding of their behaviour, i.e., cannibalism, control of environmental factors, and practical rearing techniques, still need further improvement.

Crab is a fishery commodity with a high economic value. The development of crab rearing business is expected to increase in the future. Crab production has decreased, thus it requires the strategy crab rearing business. The purposes of research are to identify internal factors, external factors and to crafting strategies of mangrove crab rearing business use natural method. This result shows that strengths are suitable position area, water characteristic, good product, distribution system, available land, own land, short harvest period, and farming period. The weaknesses are farmer knowledge, lack of fledgling in nature, lack fund, less management and little output. The opportunities are suitable clime, open possibility of market, secure area, and mangrove area. The threats are value sale, agricultural extension, pest attack, input costs, covid-19 effect, assistance government, and crab cannibalism. The suitable strategies to be developed are in quadrant I, namely aggressive strategies.
