Aquacultural techniques for floating cage are unknown in Benin that limited the
agricultural policies to increase the fish production. This study aims to clarify that
situation. Indeed, a questionnaire has been developed and computed in KoBocollect
application. The survey`s team is 19 fish farmers. The survey took place in the first
quarter of 2019 and concerns technical data. Descriptive statistics were presented and
PCA was used for statistical analysis. It was concluded that 89.47% of the fish farmers
are men and only 03.30% are aquacultural technicians. In addition, it is noticed that
604 cages are operating on the lagoon with 78.95% of the fish farmers who are owners
of 01 to 24 cages and 05.26% own more than 100 cages. The most produced fish
species is tilapia (78%). Furthermore, 63.16% of the farmer feed their fish twice per
day while 26.32% feed three times per day. Tilapia yield varies between 836 kg and
1,220.22 kg compared to Clarias yield which ranges from 825 kg to 850 kg. The simple
rate of return is 1.52 and 1.77 for tilapia and Clarias respectively. Density, feeding
frequency, year of experience, number of cages and production cycle time influences
yield.
