We are providing the following services to farmers . We are operating aqua labs to assist the farmers in the following ways.
Soil :
	Sandy clay soil is suitable for aquaculture. By testing soil pH ( optimum range 6.4 to 7.2 ) we know the requirement of lime for pond preparation. CaO (Calcium Oxide) either from shell/rock is ideal to avoid acid. Sulphate soil which is having low pH and Iron pyrites leads to stunted growth. Organic carbon should be 0.5 - 1 ppm which will indicate the nutrient quality of the soil.
Water pH :
	Optimum pH ( 8.2 to 8.6 ) will indicate the pond conditions and other parameters like DO and water color bloom density. pH, DO and bloom density are interlinked. Over bloom will lead to high pH and chances for DO problem will arise because of more O2 required by over blooms respiration during night time. pH and Suggestions: Low pH - addition of agriculture lime Stabilize pH - maintain the same pH High pH - bring down to optimum pH by application of Alum/Gypsum
Water Temperature :
	Animal behaviour, activeness, feeding depends upon water temperature. Low Temperature -reduce water exchange, change feeding time to 7 AM High Temperature - exchange more water, immediate filling one by one aerator running in noon.
Productivity of the Pond :
	Maintain the algal bloom. Early PL's consume the algal bloom also. Transparency level 40 - 50 cm of secchi disc is optimum. When the size increases it needs more turbidity. So we have to maintain the transparency level 25 - 30 cm. This transparency level is checked by secchi disc. Identification of toxic algae and thier control measures. Blue green algae such as Nostoc and oscillatoria will produce some toxin which internally necrosis the alimentary canal of the animal which leads to secondary infections of bacteria. Toxic algal blooms is controlled by more water exchange during noon and application of chelated copper. Ammonia, Nitrite, Nitrate are the urinary ( nitrogenous ) and metabolic waste products. Optimum range below 0.1ppm. These are tested by test kits. These are eliminated by more water exchange and other methods of control by probiotic of deuitrifying bacteria. Zeolite also controls the abnoxius gases. Bore water pumping source should be tested for iron content. If it is more than 1ppm shows stunted growth. Iron forms Iron Pyrites and which gets deposited on the body and delays the moulting. If whole area of the site having iron bore means pump to reservoirs and from there surface pumping to the required pond. Periodical application of lime will reduce iron content to some extent. H₂S is the by-product of decomposition of organic deposits in the pond. Optimum level is not more than 0.33ppm. It will be controlled by bottom water exchange and application of zeolite and water probiotics of sulphate reducing bacteria. More than 20ppm of sulphate will affect mouting. It reacts with the calcium ions in the ponds and forms calcium sulphate which will be deposited on the surface of the animal due to which shells looks very rough and hard, makes it very difficult for moulting.
Alkalinity Test :
	Carbonates and bicarbonates of calcium and magnesium ions of water are tested by titration method. Carbonate alkalinity optimum level range is 20 - 50ppm, Bicarbonate alkalinity optimum level range is 300 - 350ppm.
Microscopy :
	Identification of ecto commensal organisms like protozoans, fungal and filamentous bacteria and thier control methods.
Microbiology :
	Vibrio by TCBS method. Total plate count and their control methods. By using antibiotics in the severe conditions or periodical usage of soil, water and feed probiotics.
Virus Test :
	Testing for MBV and SMBV are done at our labs for nominal cost
Quality Control :
	Identification of red gill, black gill, gill fouling organisms, loose shell, soft shell, hepatopancreatic symptoms, tail rot, antennae cut, vitamin deficiency syndrome, pre and post moult condition, severe condition of white - spot.
