The results indicate that, at densities tested, white legged shrimp addition to the intensive farming of tiger shrimp polyculture is viable as species increase crop production Key words: Penaeus vannamei, P. No adding effects were found on the water quality parameters. Final  affected by white legged shrimp addition. Growth rate and total yield affected by addition of this species. White legged shrimp added at 70 day at 8Â☒ individuals/m2. Tiger shrimp were stocked in 2800-3400 m2 earthen ponds at 40 individuals/m2 and reared for 133 days.
The objectives were to assess the effect of adding white legged shrimp ( Penaeus vannamei on growth and survival of tiger shrimp ( Penaeus monodon in intensive Farming.

In the present study, the hypothesis tested was that Penaeus monodon post-larvae (PL) experience lower growth when exposed to crushed conspecifics, which was achieved by exposing individual P. The results indicated that when water was completely frozen (ω = 1 or 100%), the optimal fre.Įffects of crushed conspecifics on growth and survival of Penaeus monodon Fabricius post larvae The result obtained was built the mathematical model (19) to determine the rate of freezing water according to the freezing temperature of Penaeus monodon.
The method of determination the rate of freezing water in Penaeus monodon of freezing process was established on base the equation of energy balance in warming up process Penaeus monodon after freezing to determine specific heat of Penaeus monodon.
