“…This, according to them, was because of its cost-effectiveness in terms of design and management as well as the limited impact on the environment. The findings of Imade and Egbodon, (2021) [16] also toed the same line when they reported that the mean levels of technical efficiency (TE) of the farmers under the production systems in Delta State, South-south Nigeria, were earthen pond (0.77), concrete pond (0.76) and plastic/tarpaulin pond (0.73) respectively. This was also the case in terms of output as Abasiekong, Ogban, and Idiong, (2021) reported that there were significant differences (P<.01) among the mean output of fish per ponds from the three production systems, with earthen pond having the highest value, followed by concrete pond, and mobile pond in Cross river State, South-south Nigeria.…”
