Freshly caught Heterotis niloticus obtained from Kware Lake in Sokoto State was processed into kilishi and packaged in plastic containers, paper envelopes and polyethylene bags for determination of appropriate storage media. Results of the 16 weeks storage experiment showed that fresh kilishi of H. niloticus stored in paper envelope recorded highest moisture contents of (15.33±1.15%). Protein content of the products stored in the three packaging media significantly (pkilishi of H. niloticus packaged in paper envelope. The highest microbial counts of 5.8 x 106 cfu/g for the kilishi of H. niloticus packaged in plastic containers were recorded in week 6, but zero counts were obtained for kilishi packaged in paper envelope and polyethylene bags in week 16. From the findings of the study, storage in paper envelope and polyethylene bagis the most appropriate for storage of kilishi of H. niloticus, with respect to moisture and bacterial counts.
