Broodstock Development |
|
Farming & Sea Ranching of Spiny & sand Lobsters |
 |
Successful maturation and breeding of the spiny lobster Panulirus homarus was achieved by regulation of light intensity (500 lux) and on feeding with green mussel |
|
Fecundity, egg quality and percent hatch of captive lobsters is higher than broodstock obtained from the wild. Feeding phyllosoma larvae with Artemia nauplii hatched out from infected cysts leads to protozoan infestation. Treatment of cysts with chlorine at 200 ppm for 10 minutes keeps the larvae free from infection. |
|
Delay in feeding of phyllosoma larvae by 24 hrs. after hatching may result in delayed moulting and low survival. |
|
Short term fattening of lower priced smaller grade lobster to a higher priced larger grade is profitable |
