Analysis of Practice of Cage Aquaculture System in TohoTodougba Lagoon, Southern Benin (West Africa)

Abstract

Aquacultural techniques for floating cage are unknown in Benin that limited theagricultural policies to increase the fish production. This study aims to clarify thatsituation. Indeed, a questionnaire has been developed and computed in KoBocollectapplication. The survey’s team is 19 fish farmers. The survey took place in the firstquarter of 2019 and concerns technical data. Descriptive statistics were presented andPCA was used for statistical analysis. It was concluded that 89.47% of the fish farmersare men and only 03.30% are aquacultural technicians. In addition, it is noticed that604 cages are operating on the lagoon with 78.95% of the fish farmers who are ownersof 01 to 24 cages and 05.26% own more than 100 cages. The most produced fishspecies is tilapia (78%). Furthermore, 63.16% of the farmer feed their fish twice perday while 26.32% feed three times per day. Tilapia yield varies between 836 kg and1,220.22 kg compared to Clarias yield which ranges from 825 kg to 850 kg. The simplerate of return is 1.52 and 1.77 for tilapia and Clarias respectively. Density, feedingfrequency, year of experience, number of cages and production cycle time influencesyield.
