Good Aquaculture Practices
Pond Preparation
Why is Pond Preparation necessary?
  • To provide me a clean rearing environment and optimal conditions for my growth and survival.
  • Poor pond preparation can result in deterioration of the soils during the crop, with release of nutrients and toxic compounds to the water column, creating stress for the shrimp and environment.
  • Good pond preparation is also a proactive measure for disease management strategy.
DO NOT MISS THESE STEPS..
  • After the harvest, Completely drain and clean the pond without water and other aquatic animals.
  • Strengthen the pond and restore the Sluice gate ,inlet and outlet in good condition, to increase the water holding capacity of the pond.
  • Completely remove the deposited organic waste and black soil in pond area and plough if necessary.
  • Sundry the pond bottom until it cracks, to remove moisture, kill algal spores, benthic algal mats, and other aquatic organisms. Till the dry pond and compact to reduce turbidity and seepage.
  • Do pH check and apply Lime (kgs per hectare) as follows.
    • pH Agri lime CaCO3 (x 1) Dolomite CaMg(CO3)2 (x1/1.09) Burnt Lime (CaO) (x1/1.79) Hydrated Lime (Ca(OH)2 (x1/1.35)
    5.5 750 682 419 556
    6.0 500 455 279 370
    6.5 250 227 140 185
    6.8 100 91 56 74
  • Do proper layout of aerators to achieve maximum aeration without damaging the walls and bottom.
WATER CULTURE
Steps to follow...
Day - 1 Fill water up to 1.2M average water depth, Leave for 2 days to settle.
Day - 3 Add Bleaching 30ppm at night time when pH is low and Prepare Fermented Juice
Day - 4 Dolomite 100 Kg/pond at Noon Time and Run Aerator.
Day - 5 Add Fermented Juice 1st dose at Noon Time 100L to pond. Spread the Fermented juice
Day - 6 Add 100 Litres of Fermented Juice as 2nd dose at Noon time to the pond. Repeat Day 5
Day - 7 Add all the 200 Litre Fermented Juice as 3rd dose to the pond.
Day - 8 Apply VIRZON AQUA (Pond Water Sanitizer) 1-2 Kg /pond ,and simultaneously start
Day - 9 Apply Dolomite 50 Kg/pond and Growup (Pond Minerals) 10 Kg /pond.
Day - 10 Apply TOXBEAT 1 Kg (Soil Probiotic), RIDER 20 Kg (Zeolite) and Fermented Juice 100Litre
Day - 11 BACCHECK 1 Kg / BUG BEAT 1 Kg (Water Probiotic) and Fermented Juice 100 Litre (2nd dose) and make up fewrmented juice to 200 Litre
Day - 12 Growup 10 Kg (Pond Minerals) and Fermented Juice 200 Litre (3rd dose).
Day - 13 EDTA 5 Kg /pond at evening time.
Day - 14 Add SeedOne Growout 200 g / pond (SEED STOCKING PROBIOTIC), minimum 4 to 8 hrs

Note: Apply Fermented Juice during algal problems, pond preparation, low bloom,
