The effect of Indomie industrial effluent discharge on the fish fauna of New Calabar River was investigated in order to ascertain the influence of BOD, COD, DO, TDS, TSS, pH, salinity, phosphate and temperature on the composition and distribution of fish fauna. The diversity of the fish fauna was found to be poor, only 12 fish species in 6 families were identified. The highest number (10) of fishes was recorded in station 4 while the least number (1) of fishes was observed in station 1. The fish families were: Cichlidae (38.89%), Clupidae (33.33%), Pomadasyidae (16.67%), Bagridae (11.11%) while Genidae and Muglidae had zero percentage of fishes in its abundant. The resident fish species (Ethmalosa fimbriata and Tilapia guinensis) were highly adapted to the changes in the study environment and this was dependent on their trophic relationship within the environment. These species had great affinity for indomie industrial waste, because they feed on waste remains, mud/sediment silts and annelids, juveniles of shrimps and crabs. The deterioration of water quality was evident by the high BOD (12.80mg/L), COD (130mg/L), TDS (37mg/L), TSS (62mg/L), pH (5.2), salinity (50.54mg/L), phosphate (0.14mg/L) and temperature (27 0 C) as well as the low dissolved oxygen (2.8mg/L) values observed. It was recommended that a routine treatment of the effluent before discharge into the water should be carried out so to maintain safe levels of industrial effluent in the immediate and extended environment.

“…The LBRB lies within the middle belt zone of Nigeria which is part of the 'derived savannah' located between the tropical rain forest of the south and the Sahel savannah of the North [17]. The basin boasts of favourable climatic and soil conditions making it good for growing almost all types of crops grown in the country and its rivers accommodate over 128 different species of fish [16]. There are potentially 51 sites suitable for locating small-scale hydropower schemes along the Benue River [18].…”

“…The LBRB comprises the whole of Benue, Plateau and Nasarawa states. It is defined as 'the Benue River basin downstream of the Faro-Benue confluence' [16]. Covering an area of 90,554 km 2 , it is just under 10% of the total area of Nigeria.…”

Assessing Community Perception and Attitude towards Flooding in the Lower Benue River Basin, Nigeria

In the Lower Benue River Basin, the majority of the population derives their livelihood from subsistent farming and fishing. With climate change expected to result in increased flooding, the impacts on these poor rural farmers will be significant and since adaptation is not cheap, prioritizing responses by sectors becomes essential. Such an analysis can bring to the fore the sectors that are most affected and by implication sectors of importance to the community. Two communities: Wadata and Anyim were selected for survey. Health, housing, agriculture, economic activities, transportation and water are the sectors evaluated. Results reveal agriculture; housing; and economic activities as the worst affected sectors. In furtherance, we argue that prioritization of adaptation by sectors can provide immediate relief for victims. Vulnerability in the region is exacerbated by 'late' and 'historic incorrect' environmental change communication. Household insurance is non-existent and somewhat non-customary thus, financial adjustments are presumably made with household savings or assets disposal.

A Length-based study of the age of Synodontis schall from the lower River Benue was conducted for a period of 12 months (January-December, 2013). Length measurements (cm) were conducted on 963 samples of the fish species during the period of study. Five length-based approaches were used in analyzing the length-frequency data obtained in the 12-month period and the following asymptotic length, L∞ values were obtained: Monte-Carlos Simulation, 31.26cm; Bhattacharya's method, 30.11cm; VBGF, 37.06cm; Powell-Wetherall, 35.59cm and Jones and van Zalinge, 37.06cm. It was noted that the Monte-Carlos and Bhattacharya's methods were simulative and could have recorded lower values due to individual variability in growth parameters, seasonal oscillation in growth, size-dependent selection, variable recruitment period and large length-class intervals used in grouping length data. It was also observed that Synodontis schall in lower River Benue attained its maximum length at age 3+ suggesting short longevity of lifespan. It was concluded that length-based age study was the most reliable approach in studying fish stocks in the tropics especially in these moments of ecosystem variability occasioned by global warming.
