Influence of Probiotics on Water Quality and Fish Yield in Fish Ponds
Increased production of fish through intense culture practices often leads to not only stress and disease problems but also alteration in water quality. The organic wastes and bad water quality influence the growth of pathogenic microorganisms. Bioremediation using pond probiotics is considered a promising way to circumvent these problems. For this study, three earthen fish ponds stocked with P...
متن کاملManaging Ammonia in Fish Ponds
Ammonia in water is either unionized ammonia (NH3) or the ammonium ion (NH4). The techniques used to measure ammonia provide a value that is the sum of both forms. The value is reported as “total ammonia” or simply “ammonia.” (In this publication, “ammonia” refers to the sum of both forms; the specific forms will be referred to as appropriate.) The relative proportion of the two forms present i...
متن کاملOptimal water quality for keeping ornamental fish in the aquarium
Ornamental fish keeping is the second most popular hobby in the world, and its popularity is growing every day. The ornamental fish farming industry provides entrepreneurship and income generation opportunities, so it is important to focus on various aspects of ornamental fish farming. Several physical and chemical parameters of water are discussed in this study, including pH, hardness, a...
متن کاملEffects of rainfall on water quality in six sequentially disposed fishponds with continuous water flow.
An investigation was carried out during the rainy period in six semi-intensive production fish ponds in which water flowed from one pond to another without undergoing any treatment. Eight sampling sites were assigned at pond outlets during the rainy period (December-February). Lowest and highest physical and chemical parameters of water occurred in pond P1 (a site near the springs) and in pond ...
متن کاملWater quality management in earthen ponds using an optimum carbon/ nitrogen ratio
The main goal of the current study was to evaluate the effects of C/N ratio on water quality parameters and production level at high stocking density pond. The C/N ratio of the experimental ponds were arranged by addition of corn starch to the pond. There were three treatments in the current study; control one without corn starch addition and treatments two and three which contain C/N rations o...
