This study assessed the marketing practices and strategies of smoked fish within selected markets in Maiduguri. The findings revealed that males dominated the marketing of smoked fish with 69 (86.25%), primarily within the age range of 41-50 years with 28 (35%), with Arabic education as the predominant educational qualification with 37 (46.25%). The majority of marketers were of Kanuri ethnicity with 45 (56.25%) and operated as retailers with 53 (66.25%), utilizing public transportation with 49 (61.25%) for fish distribution. Clarias gariepinus was identified as the most marketable fish species with 35 (43.75%), with cartons being the preferred packaging material with 49 (61.25%). Open market display was the dominant marketing strategy with 45 (56.25%), with texture being the primary factor determining price with 59 (73.75%). High-quality packaging was also found to significantly influence sales with 48 (60%). However, marketers faced challenges such as price fluctuations, lack of government incentives, limited capital, and high transportation costs. The study’s findings provide valuable insights into the marketing practices and strategies of smoked fish in Maiduguri, highlighting areas for improvement and potential interventions to support marketers.

Study on the ichthyofauna and physico-chemical parameters of Guma River, Obi Local Government Area of Nasarawa State, was carried out for a period of four months (April-July, 2021). Fish specimen were obtained from the fishers fishing in the river while water sample were analysed twice a month using Lamotte aquaculture testing kit. The result showed that a total of 21 fish species belonging to 10 families were present in the river which was considered rich enough for that type of water body. The families Cichlidae, Characidae, Mormyridae, Bagridae and Clariidae constituted the dominant fish species in the river with 31.11%, 15.98%, 15.00%, 11.95% and 8.20% respectively. The result further shows that most of the fish species has condition factor above 1, with Sarotherodon galileaus having the highest condition factor of 3 while Clarias anguillaris has the lowest condition factor of 0.88. The result of water quality showed slight variations in the monthly means and station values. Despite these variations, the values obtained were within the recommended range for f ish culture, for most of the tropical freshwater fish’s production.
