Clarias gariepinus Burchell, 1822 is a catfish with high commercial value in the Democratic Republic of Congo and in several African countries. The breeding of this species is controlled, but Congolese fish farmers are confronted with the problem of a lack of compound feed in the form of granules. The recovery of local agricultural waste would be essential to fill this gap. The objective of this study is to evaluate the effect of three types of food based on local agricultural by-products on the growth of C. gariepinus. The 25%, 41% and 51% crude protein feed formulas were tested in duplicate for 96 days. Fry averaging 2.20±0.43 g were distributed in 6 closed-loop plastic containers. The fish were fed twice a day by hand. Weighing and measuring took place every 14 days. The results obtained show that the highest final average weight (g) and specific growth rate (%/d) (F = 2.87; p = 0.002) are obtained with food A1: 27.5±1.9 g and 0.25±0.15% /d respectively. It took 812.6 Congolese francs to develop food A1, 942.6 congolese francs to produce the A2 ration and 836.6 congolese francs to produce food A3. The A1 ration is the one that gave a better compromise in price and quality by promoting fish growth at a lower cost (3.827 congolese francs).

The current state of large cities in Democratic Republic of Congo highlights the necessity of reinventing cities. More than fifty years after the independence, these major cities, like Kinshasa the capital city, are in a state of are in a state of disrepair. They are damaged, dysfunctional, and more vulnerable. Today, these legacy cities do not meet the international requirements of livable cities. Democratic Republic of Congo faces the challenge of rebuilding its cities for sustainability. The movement for independence of African countries enabled the shift from colonial cities to legacy cities. It is important to understand the cultural and ideological foundations of colonial city. Commonly, colonial cities served as purpose-built settlements for the extraction and transport of mineral resources toward Europe. What's required is a creative reconstruction to achieve a desired successful urban change. Creative reconstruction tends to ensure urban transformation in relation with urbanization, by making continuous and healthy communities. Creative reconstruction seems appropriate way of building back cities in harmony with cultural values. The article provides a framework for urban regeneration. The study is based on principle of thinking globally and acting locally in building back better cities.
