Comparative evaluation of different carbohydrates as dietary energy source for the mud crab Scylla serrata megalopa
The study was conducted to determine the type of dietary carbohydrate source essential for the survival, molting, efficient growth and body protein content of the megalopa larvae of mud crab Scylla serrata. Following a completely randomize design, eighty (80) S. serrata megalopa larvae were fed diet...

| description | The study was conducted to determine the type of dietary carbohydrate source essential for the survival, molting, efficient growth and body protein content of the megalopa larvae of mud crab Scylla serrata. Following a completely randomize design, eighty (80) S. serrata megalopa larvae were fed diets containing different carbohydrate sources: (i) starch, (ii) sucrose, (iii) glucose and (iv) dextrin until they were able to molt into the crab instar I stage. The feeding trial results showed no significant difference (p |
