“…Due to the limited availability of land culture resources and the high demand of the consumer market, intensive aquaculture has become the main mode of culture in crustaceans (1,33,36) . Nevertheless, intensive aquaculture can cause physiological and metabolic disorders and hypoimmunity that can lead to increased disease (37) .…”

“…The mud crab (Scylla paramamosain), a typical marine omnivorous crab species, is widely distributed in tropical, subtropical and temperate zones of Asia (1) , and due to its delicious flavour and nutritional quality, it is increasingly favoured by seafood consumers (2) . However, wild populations of mud crab have dramatically declined in recent decades due to over-fishing and environmental deterioration (3) .…”

“…However, wild populations of mud crab have dramatically declined in recent decades due to over-fishing and environmental deterioration (3) . With the success of larval cultivation, mud crab has become one of the most important aquaculture crustacean species in Asia, especially China (1,(4)(5)(6) . Mud crab production in China reached 157 712 tons in 2018 and accounted for 66•5 % of total production (7) .…”

“…However, with increasing wild fishery and marine environmental protection, the traditional feeds of trash fish and shellfish are insufficient to meet the requirements of crab culture (8) . Thus, studies on the nutritional requirements of mud crabs are important to develop cost-effective, environmentally friendly and nutritionally balanced formulated feed for mud crab (1) . To date, studies have reported the nutritional requirements of mud crab for protein, lipid and phospholipid (2,(9)(10)(11) ; however, few researchers have focused on trace element requirements of mud crab.…”

The aim of the present study was to investigate the effects of dietary Zn level on growth performance, Zn bioaccumulation, antioxidant capacity and innate immunity in juvenile mud crabs (Scylla paramamosain). Six semi-purified diets were formulated to contain dietary Zn levels of 44·5, 56·9, 68·5, 97·3, 155·6 or 254·7 mg/kg. Dietary Zn level significantly influenced percentage weight gain (PWG), with the highest observed in crabs fed the diet containing 97·3 mg/kg Zn. Tissue Zn concentrations significantly increased as dietary Zn levels increased from 44·5 to 254·7 mg/kg. Retention of Zn in hepatopancreas increased with dietary Zn levels up to 68·5 mg/kg and then significantly decreased. Moreover, inadequate dietary Zn (44·5 and 56·9 mg/kg) reduced antioxidation markers including total superoxide dismutase (SOD) and Cu/Zn SOD activities and total antioxidant level. Crabs fed the diet with 44·5 mg/kg Zn also showed significantly lower expression of genes involved in antioxidant status, such as Cu/Zn SOD, glutathione peroxidase, catalase and thioredoxin than those fed diets containing 68·5 and 97·3 mg/kg Zn. The highest activities of phenoloxidase and alkaline phosphatase were recorded in crabs fed the diets containing 68·5 and 97·3 mg/kg Zn. Expression levels of prophenoloxidase and toll-like receptor 2 were higher in crabs fed the 97·3 mg/kg Zn diet compared with crabs fed the other diets. Based on PWG alone, the optimal dietary Zn level was estimated to be 82·9 mg/kg, with 68·5 to 97·3 mg/kg recommended for maintaining optimal Zn bioaccumulation, oxidation resistance and innate immune response of juvenile mud crabs.

“…Newly hatched mud crab larvae which lacks of yolk sac are hungry and need immediate feeding [35][36][37]. They are free swimmer and natural predator to the live prey, but the swimming activities of Z1 larvae are not so swift as to capture prey of the first movable objects, that indicates inefficient predator behavior and are passive feeders depending on options of encounter with food [38].…”

Effect of essential fatty acids (EFA) on growth and survival of the green mud crab (Scylla paramamosain) larvae was assessed by feeding with natural to commercial diets. The feeding schemes were: larvae reared with Artemia (T1); larvae initially fed with rotifers (up to Z2) and ended (Z3 to megalopa) with Artemia (T2); and larvae fed with rotifers up to Z2 and ended (Z3 to megalopa) with commercial diet (T3). The commercial diet had significantly (p<0.05) higher levels of docosahexaenoic acid (11.23%), ∑n-3's (15.90%) and ∑n-6's (4.21%); and lacked in eicosapentaenoic acid (2.25%) than rotifer and Artemia. The earliest commencement of megalopa stage within 15 days with significantly (p<0.05) higher larval stage index (LSI) of 5.90±0.17 was achieved from the feeding scheme of T2 than other two feeding schemes. This feeding scheme deposited 17.32±0.19% eicosapentaenoic acid (EPA) and 3.82±0.11% docosahexaenoic acid (DHA); the ∑n-3 to ∑n-6 ratio of 0.20 and EPA to DHA ratio of 0.22 in megalopa, that stimulated significantly higher (p<0.05) megalopa survival (20.00±6.96%) indicating the superiority over rest feeding schemes. Meanwhile, some deformities and mortalities in Z5 and megalopa stages suggested further studies for optimization of specific fatty acid requirements for late larval stages (Z5 and megalopa).
