  abstract = {{A}ll predictions agree that tilapia is destined to become the major aquaculture species of tomorrow. {T}ilapia is grown in more than 100 countries and production reaches 4.3 million tonnes making this fish group the second largest for global aquaculture, after that of carp. {T}he modern development of its breeding requires energy for production systems e.g. to supply oxygen equipment or automatic food vending machines or the heating of livestock ponds. {T}his work proposes to valorise the waste resulting from the activities in fish farming by the processes of anaerobic digestion to produce energy. {F}or this, faeces of {T}ilapia {O}reochromis niloticus were sampled periodically and their methanogenic potential ({BMP} test) determined and compared to a reference substrate (poultry droppings); with or without inoculum. {T}he μ{CG} analysis made it possible to determine the relative proportions of methane ({CH}4) in the biogas as a function of the duration of production. {B}iochemical methane potential ({BMP}) tests showed rapid kinetics of biogas production of fish faeces in the presence of inoculum (+ inoculum) compared with the production of biogas in faeces alone. {T}his kinetics of biogas production is reversed between the third and fourth week. {I}n both cases, the proportion of methane is generally greater than 60% from the second week of incubation, which shows the quality of the biogas produced. {T}he composition of {CH}4 and {CO}2 does not change with or without inoculum. {H}owever, there is a significant difference in total {CH}4 volume which is twice as large with inoculated fish faeces than uninoculated fish or poultry droppings. {O}ur results show that fish droppings are good methanogenic substrates and the use of the inoculum allows for a quick start of biogas production and avoids {MO} losses. {R}ealized on a large scale, the valorisation of aquaculture fish faeces could constitute a source of green energy for the development of fish farming in {A}frica. {A}nd thus a smart initiative to fight against climate impact on small pelagic fish stock displacement in tropical areas.},
