Dear Researcher R. K. Mohanty,
Yes I can share my experience. I gathered some Thirteen (13) months of practical work experience as Junior Consultant (Part-time) starting from 01 July 2009/ 23 August 2010 in a fish farm namely Noakhali Integrated Agro Industries Limited (NIAI Ltd.), Sonapur, Noakhali Sadar, Noakhali, Bangladesh. In NIAI Ltd they rigorously used underground water for fish farming ad hatchery operation and many times they suffer from low dissolve oxygen (DO) and or even excess iron (Fe) in water. However, would you please explain or specify actually what kind of information you want to know.
Yes, In Namibia ( southern Africa) we have two grow-out aquaculture capital projects that are supplied with underground water. We farm with tilapia, common carp, and catfish at these projects and we always record a normal growth performance. One of the projects has been in operation for about 8 years now, and the water quality still remain good for both aquaculture and household consumption. We apply the same water quality management practices as we do at fish projects that use rain water from open reservoirs. At some regions in Namibia underground water is better preferred for aquaculture, for the reason that it is more clean (no suspensions) compared to open water which need too much preparation (settling) before it is used especially in the hatchery.
You can contact my colleague M.S. AZAZA ([email protected]), he works on Tilapia culture in geothermic waters in the south of Tunisia. Different topics were studied : eg; reproduction, growth, nutrition...
Please share my experience also. I was able to visit tilapia farm in Egypt which was operated in dessert area . They extracted geothermic waters from a deep well which depth was around 300m. Just water come to the surface there is a storage reservoirs (tank) consists of peddles wheels to circulate water with ambient oxygen before drain to tilapia ponds. They also suffers high concentration of Ferric in ground water but i was unable to grabbed the solutions.
Dear Pannipiti Arachchilage Don Ajith Kumara ,
Sincere thanks to you for sharing your experience and actually the problems with ground water in many parts of the Globe is some what more or less similar like this.
Regards
MM Hossain
I have managed a fish farm(5 ha) exclusively Gordon groundwater drawn by not well.this water was poor in o2,rich in iron,CA and always created problem in carp seed production especially egg fertilization 2 hatching.problem was solved by mixing earlier filled pond water in hatchery tanks during the breeding process.in culture practices water was drawn in pond, fertilized and allowed 2 mature for 10-15 d then stocked and follows culture practices.once/ week relinquished water about 10%of vol owing to seepage who h wS controlled in coming yr mistreatment of sod.carbonate.no other problem all grow out craps weighed 800g-1.2kg and production ranged 7,-8k kg /ha/ 9 months.
Respected Mr. Mohanty,
Here at the Fisheries research farms, university of Agriculture, Faisalabad, we exclusively use groudwater. Production is good.
Some aspects should be kept in mind while using the groundwater;
1: determine the alkainity of water.
2: determine the salinity of water.
3: determine the hardness of water.
4: water should be run in open channels for getting well oxygenated before putting in into the ponds.
I personally recommend the duck cum fish culture. This integration provides oxygen and natural fertilizer for the ponds. And you can get a handsome amount by selling the duck eggs and flesh in addition to fish protein.
Hi
What is the minimum limit required for sulphate in the underground water used for aquaculture of carp?
Let me share my experience. Me and some of my friends have already started the cultivation of vietnam koi fish (8000 fingerlings) in a land of approximately 3 decimal. We are providing underground water twice a week from a shallow (25 feet) through water pump. However, after 20 days we observed that, on an average, fingerlings of 3000 lines turns into 320 lines, i.e. a quite satisfactory growth rate. It is to be noted that, till now we have not suffered any water problems and the whole process undergoes in a smooth manner.
