Lime sludge waste of paper mill as an alternative source of liming in fish farming

Abstract

LIME SLUDGE WASTE OF PAPER MILL AS AN ALTERNATIVE SOURCE OF LIMING IN FISH FARMING The thesis consists of five chapters under the broad headings of (i) Introduction (ii) Materials and Method (iii) Results (iv) Discussion and (v) References. CHAPTER 1: INTRODUCTION In this chapter a brief description of the pisciculture has been incorporated. The importance of fish has also been illustrated. A brief description of the freshwater aquaculture of our country has been illustrated with main role of fish farming. The status of the fishery in Assam has also been incorporated. The different physico-chemical properties required for fishery has also been illustrated. The importance and benefits of liming in fisheries and also the different liming materials in fishery were incorporated. Since the focal point of the present work is the alternative source of liming in fishery. The role of industrial solid waste specially the lime sludge waste of paper mill has been incorporated since it is used in the present investigation. The effects of this solid waste on soil quality and water were highlighted with some relevant literatures. The chapter is basically a review of some selected literatures on topics related to the present study. Though there is lack of literatures directly related to the present work yet, some important literatures were highlighted which were indirectly related to the present work. The importance of the present investigation has also incorporated. At the end of the chapter the objectives of the study were also discussed. The objectives are------ also incorporated. At the end of the chapter the objectives of the study were also discussed. The objectives are------ To analyze the various physico-chemical properties and toxic metals present in the lime sludge waste of Jagiroad Paper Mill of Assam. To study the impact of application of lime sludge waste on water quality parameters and also on fish growth in experimental aquaria cultured in the laboratory. To evaluate the impact of application of lime sludge waste...
