 ABSTRACT

In the present study biological method with 15 % molasses and 10% curd were used for preparation of fish silage. The important findings are summarised as: the chemical analysis of fish market waste was observed on wet basis to be moisture 77.09 ± 0.14 %, crude protein 15.20 ± 0.15 %, lipid 4.03 ± 0.07 % and ash 3.30± 0.11 %. Rice bran was used as co-drying material for drying liquid silage. The proximate composition of rice bran contained moisture, crude protein, fat and ash as 9.45 ± 0.19 %, 16.05 ± 0.08 %, 13.42 ± 0.15 % and 10.44 ± 0.14 % respectively on dry weight basis. Powder fish silage was prepared by mixed liquid silage with different quantity of rice bran.  For neutralizing the liquid fish silage 1.5% sodium carbonate was added and measured pH value was 6.45. Mixtures were dried within 2-3 days in solar tunnel drier. The proximate composition of powder fish silage made with different quantity of rice bran 10, 20, 30, 40 and 50% contained moisture content as 13.74 ± 0.12, 12.54 ± 0.30, 10.91 ± 0.13, 10.18 ± 0.05, 9.18 ± 0.02 % respectively; crude protein content as 29.50 ± 0.22, 28.56 ± 0.12, 27.66 ± 0.10, 26.53 ± 0.18, 25.73 ± 0.08 % respectively; fat content as 16.28 ± 0.11, 15.71 ± 0.14, 14.45 ± 0.11, 13.73 ± 0.17, 12.60 ± 0.10% respectively; ash content 14.21 ± 0.12, 14.55 ± 0.11, 15.27 ± 0.13, 15.65 ± 0.15, 15.99 ± 0.12 %  respectively. Considering all the limitation, powder fish silage with 30 % rice bran was found to be better and carried for further storage study. During storage, moisture content of powder silage was increased in the range from 10.91 ± 0.14 to 11.15 ± 0.10 ,whereas the protein content was decreased in the range from 27.66 ± 0.10 to 27.04 ± 0.06 %, fat content decreased in the range from 14.45 ± 0.11 to 13.42 ± 0.10 %, ash content decreased in the range from 15.27 ± 0.11 to 14.60 ± 0.09 %, Fiber content decreased in the range from 9.89 ± 0.06 to 9.64 ± 0.07 %, Carbohydrate content increased in the range from 21.82 ± 0.07 to 23.14 ± 0.11 %, pH increased in the range from 6.45 ± 0.05 to 6.59 ± 0.14 and TPC increased in the range from  2.10×104 to 2.36 ×104  cfu/g during the storage period from 0 to 90 days.
From above study it can be concluded that fish market waste is suitable for preparation of fish silage powder.  At room temperature powder fish silage could be stored up to more than 3 months without loss of major nutrient components.
