Shrimp aquaculture in India: Present status and way forward 16 4. The yield, quality, size and uniformity of stock are all significantly impacted by water quality parameters, which must be closely monitored and controlled for the best results. One of the major limiting factors in aquaculture production is poor water quality which can negatively affect the yield from aquaculture venture. Most aquatic organisms need oxygen to survive and grow. 0000002194 00000 n Each water quality parameter interacts with and influences other parameters, sometimes in complex ways. You may need to "scoop" water into the bag by drawing it through the water upstream and away from you. Do not fill the bottle completely (so that the sample can be shaken just before analysis).
