This paper examined climate change adaptation strategies in fish farming and the effect of such methods on the profit of fish farmers in the Niger Delta region of Nigeria, Africa’s most populous country. Using cross‐sectional data obtained from 420 fish farmers from the region and applying multivariate probit and instrumental variable regressions, the study found that fish farmers have adopted a broad range of strategies to address climate risk and that these have significantly increased farmers’ profit. Our findings indicated important relationships between certain farm, socio‐economic and institutional characteristics and the adaptation actions. The study provides useful insight into factors that potentially encourage the adoption of livelihood‐enhancing climate risk adaptation strategies by fish farmers in the Niger Delta region and similar contexts.

This experiment was conducted to investigate the effect of two processing methods (smoking and solar drying) on the proximate content, organoleptic characteristics and nutritional qualities of Clarias gariepinus. The moisture content of the smoked fish sample was lower (8.10%) than that of the sun dried sample (25.00%). The crude protein, carbohydrate, fat, ash, crude fibre and nitrogen free extract of the smoked fish sample were 67.20, 1.75, 13.20, 5.50, 3.68 and 2.32%, respectively, compared to 52.50, 4.07, 17.40, 11.40, 2.00 and 18.30% observed in the sun-dried fish, respectively. Mean scores of organoleptic evaluation showed that both processed fish products were preferred (≥ 7.00) by the trained panellists. However, there was significant difference (p<0.05) between the two processed fish products in terms of organoleptic assessment. Smoked fish had better flavour, taste, texture and general acceptability than the solar-dried fish as revealed by the panellists. With better reduction in moisture content and higher protein content observed in fish subjected to smoking, it is concluded that smoking is better than solar drying in the processing of C. gariepinus.

The present study measured household hunger in South-East Nigeria amidst the COVID-19 lockdown. A total of 1209 households (urban and rural locations) were sampled. Household hunger was determined using the Radimer–Cornel hunger scale. Results show that before the COVID-19 lockdown, hunger prevalence in the urban areas was 85.5%, whereas prevalence in the rural areas was significantly lower, at a prevalence of 79.9% (7.3% level of association—X2 = 6.499, p = 0.012). During the COVID-19 lockdown, the prevalence of hunger in the urban areas rose to 98.0% and 99.2% in the rural areas (4.9% level of association was X2 = 2.888, p = 0.089). It was also observed that the COVID-19 lockdown significantly affected food prices. The major coping strategy employed by households was relying on less expensive foods (81.14%). High household hunger was identified as a short-term cost of the COVID-19 lockdown in South-East Nigeria. Only a few households (16.3%) benefited from the food aid programs and 16.9% from the government palliative cash transfer. It is recommended that the government setup a formidable unit that will develop physical and digital plans for effective implementation during a COVID-19 lockdown situation or other emergencies.
