2.2 million hatchery produced postlarvae of the green tiger prawn Penaeus semisulcatus were searanched in the Gulf of Mannar. |
|
Experimental farming of Penaeus monodon yielded 1051 kg of shrimps with an FCR ranging from 1.59 to 1.77. |
|
Induced maturation and breeding of P. monodon by artificial insemination technology is standardised. |
|
Third generation of P. monodon seeds is produced from domesticated broodstock. |

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 |
