Hardbound. Zustand: As New. Contents: Preface. 1. Introduction. 2. Environment and organism. 3. Pond bottom treatment. 4. Fish diseases. "To enhance aquaculture production, high stocking rate followed by heavy dose of fertilizers and feed influence the environmental stress factors exceeding acclimation tolerance limits of the cultured stock. As a result the occurrence of frequent fish disease epizootic lead to mortality of fish and decline in fish population.In fact, the production of fish show negative correlation with the environmental stress and disease. The various fish diseases of economic importance identified until now include ulcerative dropsy, columnaries disease, trichodiniasis, white gill spot, white scale spot, dactylogyrosis,black spot, ligulosis, ergasilosis, lernaeosis, argulosis, branchiomycosis and saprolegniasis, have been outlined in the book.
