Pada setiap bak dipelihara 30 ekor benih selama 30 hari. Percobaan dilakukan dalam dua tahap; tahap pertama menguji tiga jenis substrat (pasir, koral dan lumpur) yang ditempatkan di dasar bak dengan ketebalan 3 cm; sedangkan pada tahap kedua ditambahkan pelindung (shelter) berupa potongan pipa PVC yang berdiameter 0,75 inch dengan panjang 10 cm yang ditempatkan pada setiap bak masing-masing sebanyak enam buah.

In the first experiment mud crab seeds were reared in fiber glass tank of 50 x 40 x 40 cm3 at the initial stocking density of 30 crablet/tank. The tanks were filled with filtered seawater to a depth of 30 cm and aerated. Each tank was provided with a 3 cm thick layer of bottom substrate. The rearing substrate tested in this experiment were sand, coral and mud. Each treatment was run in three replicates. The second experiment was conducted by providing in each tank six pieces of PVC tube (0.75 inch diameter) of 10 cm long to serve as shelter. Pieces of shrimp were given as feed to mud crab once a day at 50 % of total body weight. No significant differences on survival was observed among treatments in the first experiment. After 30 days the survival of crab reared in sand, coral and mud substrates were 23.3 %, 20.0 % and 18.4 %, respectively. The growth, however, was significantly affected by the treatment. The crab reared in mud substrate had a significantly (P<0.01) better growth of carapace width (27.51 mm) and length (19.79 mm) as compared to the crabs reared in sand substrate (21.05 mm width; 15.11 length) and coral substrate (20.26 mm width; 14.54 length). In contrast, the growth of crab carapace was not significantly affected by the substrate treatment in the second experiment. The crab survival in this experiment was improved by providing shelters. The crabs reared in sand substrate had a significantly higher survival (41.3 %) as compared to the mud substrate treatment (29.3 %), but there was no significant difference with coral substrate treatment (34.7 %).
