§16§Master's Thesis from the year 2004 in the subject Biology - Zoology, grade: M SC, Jahangirnagar University (Faculty of Biological Sciences), course: Fisheries (Zoology), language: English, abstract: To inquest a pertinent technology of preservation seasonal (summer, autumn, winter) nutritive values, effects of potassium sorbate, gamma radiation and their combinations preserved at low temperature on sensory, chemical and microbial properties of freshwater prawn (Macrobrachium rosenbergii, de Man-1879) as well as isolation and identification of associated micro-flora with their sensitivity to potassium sorbate and gamma radiation were investigated during February 2003 to April 2004. Nutritive analysis marked seasonal and body-part variations in moisture, protein, lipid, ash, calcium and phosphorus contents i.e., summer, autumn and winter as 80.07%, 80.37%, 76.99%; 19.20%, 18.03%, 21.30%; 1.23%, 1.07%, 2.99%; 1.48%, 2.00%, 1.21%; 0.19%, 0.21%, 0.14% and 0.10%, 0.08% 〓16§-part while 77.27%, 76.27%, 73.34%; 16.45%, 17.03%, 19.79%; 1.40%, 1.02%, 4.33%; 6.60%, 7.33%, 6.25%; 2.24%, 2.78%, 1.67% and 0.17%, 0.15% 〓16§illus subtilis (20.33%), Micrococcus varians (16.67%) and Escherichia coli (13.33%) were frequent species. Among 10 mould strains - seven (70.00%) were collected from control, three (30.00%) from radiation treated while no colonies were found from chemical and combined treated samples. Total 4 genus of moulds were identified in which Aspergillus (40.00%) was dominant.
