Green House HDPE Liner Pond-Enhanced Hatchery Seed Production In Malaysia Condition

Malaysia is in the tropical region with annual rainfall ranged from 1500-2500 mm. The monthly average rainfall is from 120-200 mm, during raining season, the water of the aquaculture ecosystem will  be affected.

The nature of rainwater normally with pH 5.5-6.5 ,salinity is 0 ppt, alkalinity is  0-5 ppm. During raining dissolved oxygen will be lower than normal with lower temperature as well. Rain water seepage during raining day results low pH low alkalinity and high soluble iron in coastal aquaculture earth ponds excavated on acid sulfate soil. Low and poor survival of the seed production in tropical countries are  teething problems for the hatchery operators that result financial lost.

With many years of hatchery operation in open mesocosm system in earthen pond that experienced , STAC provided a consultancy  commercial project in 2006 in Labuan and 2010 in Tanjong Karang using Green House HDPE Liner Pond for hatchery production of marine fish seed and marine crab seed production, the results proved the system is commercial viable and sustainable.

A third project is carried out at Bagan Segaris of Pantai Remis of Perak in a 6.5 acres coastal land with acid sulfate in nature where 3 x 1000 m2 Green House and HDPE Liner Ponds,3 x 250 m2 Green House HDPE Liner Ponds Brood Stocks and 3 x 3 000 m2 Liner Pond for nursery and reservoirs are in operation.
