Abstract:
This study was carried out to assess the zootechnical performance of a domesticated strain of Clarias gariepinus compared with a wild strain of Clarias senegalensis. This work was performed on 4g juveniles reared in tanks and obtained by artificial reproduction using 3 males and 2 females for each species. The experiments were carried out in the hatchery of the Agence Nationale de l'Aquaculture (ANA) fish farm in Richard-Toll. Fish were divided into two ponds, with 38 juveniles of C. gariepinus in pond P1 and 37 of C. senegalensis in pond P2. During the 21-day rearing period, temperature values (ranged from 25°C to 29.5°C) and pH (from 7.48 to 8.13) were those recommended for the breeding of species of the Clarias genus. Growth data were obtained by evaluating various growth parameters. Data on average weight gains showed that C. gariepinus had the best results with an average weight gains (AWG) of 8.13g, compared with 4.47g for C. senegalensis. Concerning the feed conversion ratio (FCR), C. gariepinus had the lowest value (1.80 compared with 2.21 for C. senegalensis), which also means that this fish assimilates the food more efficiently. Similarly, C. gariepinus also showed the best Specific Growth Rate (SGR) (9.97%/day) compared with C. senegalensis (7.13%/day). These results revealed that C. gariepinus performed better than C. seneglensis for all the variables studied, but suggest that this latter species of Senegalese strain could indeed be reared in captivity.
