“…Similar observation was reported by Mustapha (2009) and Dankishiya et al (2012). The present finding also conforms with the works of other authors within the same ecological zone such as Lamai and Kolo (2003) who identified 4 fish families consisting of five (5) In the present study Tilapia zilli (family Cichlidae) was the most abundant with (36.7%) in the dam while Protopterus sp. had the least with (2.8%).…”

The diversity, length-weight relationship and condition factor of fish species of Thomas Dam, Dambatta Kano were studied fortnightly between November, 2016 and February, 2017. Fish species were collected using line nets, cast nets, hooks and traps; weighted to the nearest gram and standard length measured to the nearest centimeter. A total 313 fishes comprising of 7 families and 11 species were identified.

“…The result of this study agrees with the finding of (Nazif and Abubakar, 2013), where they have identified fifteen (15) species of fish representing eleven (11) families in dadin Kowa Dam Gombe State. While the result of this study Disagrees with the finding of (Lamai and Kolo, 2003), where they have identified five (5) species of fish representing four (4) families in Dan-Zaria dam. The result of this study Disagrees with the findings of (Ekeanyanwu, 1980) in river delmi jos where seven (7) genera were identified, Anthony et al (1986) recorded four (4) species in Auree reservoir near plateau state.…”

Introduction Freshwater ecosystems are among the most dynamic and diverse ecosystems and are estimated to maintain over 10,000 species of fish (Nelson, 1994). Nigeria is blessed with over 14 million hectares of reservoirs, lake, ponds and major rivers able of producing over 980,000 metric tons of fish annually (FDF, 2003). Statistical surveys have shown that the need for fish in the country exceeds supply also; domestic production is still very low, in view of the increasing human population. Production from aquaculture is growing compare to artisanal sources and supplied between 5-22% of total domestic fish production between 2000 and 2007 (FDF, 2007). This increasing production is not capable to meet up the growing rate of consumption because of the wide gap between fish demand and supply, which is on the increase as a result of population outburst in the country in the recent years (Falaye and Jenyo Oni, 2009). Fishes are also play an importance role for the supply as much as 17% of the world's animal protein (Olusola and Arawomo, 2008).Gubi reservoir is one of such numerous reservoirs in the country not primarily constructed for fisheries purposes, but could serve as a potential water body for fish production. Justification of the study: Aquatic environment become a major habitat for waste disposal, planting of crops, fishing, washing and bathing etc. These have a major impact on water quality as well as fish species diversity. Fish species diversity served as a bio indicator, bio accumulation and bio remediation. The aim of this study is to assess the fish species diversity in Gubi reservoir Bauchi State. The objective of this study is to determine the fish diversity in Gubi reservoir. 2. Material and Method 2.1. Description of Study Site Gubi reservoir has a total surface area of 590 km 2 , a depth of 27m, top crest width of 10m, base width of 190m and has a total catchment area of 179km 2. the surface of the water in Gubi reservoir is mainly coming from three tributaries namely, Gubi river, tagwaye river, link with shadawanka and ran river, is located at firo a village about 12 km north east of Bauchi metropolis and 8 km off Bauchi Maiduguri road. The primary purpose of providing potable water to Bauchi and its environs. A part from improving water supply to the populace, it provides the bulk of fish consumed in the town as well as providing suitable sites for fadama farming resulting in the production of some highly favoured selected crops (Ezra and Nwankwo 2001). The reservoir lies within the boundary of longitude 10 0 25' N to 10 0 26' N and latitude 9051' E to 9 0 52' E (Wufem et al 2009).

“…Abdullahi and Indabawa (2005) show that the phytoplankton of River Hadejia consists of Chlorophyta (40%), Cyanophyta (30%) Bacillariophyta (24%), Euglenophyta (35), Dinophyta 1%) and Chrysophyta (0.6%). Lamai and Kolo (2003) studied the zooplankton of Dan-Zaria dam and observed about 40 taxa dominated by the Rotifers (35.38%), Protozoa (27.03%) Cladocerans (25.54%) and the Copepoda (12.05%).…”
