1. INTRODUCTION

I was assigned to the project fish culture station in , where I worked for two years. My work involved the construction of the fish station, organising the research and production on the station and managing the extension programme.

All goals were surpassed. The station, which was more than doubled in area, is now producing over two tons of Tilapia per year. The extension programme, whose goal was one hundred private fish ponds now has 481 private fish ponds.

2. STATION CONSTRUCTION

Slightly over one hectare (10,062 m2) of fish ponds four houses (481 m2), 750 m of road and 1014 m. of canal were built entirely by hand labour. The total cost was 19,202 U.S. $. The fish ponds cost 1.18 U.S.$ per m2 and the locally fabricated buildings with tin roofs cost 6.96 U.S.$ per m2 (A conversion of 230 F.EFA = 1 US $ is used throughout).

3. STATION PRODUCTION AND RESEARCH

Full details of all pond stockings and drainings were record and while these do not form a cohesive unit, they provide a basis for future research at the station. Species used were Tilapia nilotica and Clarias lazera. The mean nette production with T. nilotica was 2,787 kg per hectare per year. The mean conversion ratios for the fish feeds used, chrushed cotton seed and abattoir waste, were 8.01 and 22.74 respectively. The crushed cotton seed cost 7.06 F.CFA per kg and abattoir waste 0.7 F.CFA per kg giving costs per kilo of fish produced of 56.5 F.CFA and 15.9 F.CFA respectively.

The growth of the young Clarias lazera fingerlings which were brought to the station was carefully monitored (max 3.23 gm per d than mature females of C. lazera were available reproduction tria were made. Lack of suitable ponds and lack of mature females, limited the Clarias research. A total of 177 one-month-old Claria lazera fingorlings were obtained from 22 attempts at induced reproduction (17 spawns) using the synthetic hormone DOCA. From 19 attempts at natural reproduction (8 spawns) 1807 one month-old fingerlings were obtained. It is confidently hoped, that observat recorded at the station during the months of August and Sept 1976 will be extremly in providing mature females of C. lazera throughout the year, which up to now has been a major stumbling block in the culture of this species.

4. THE EXTENSION PROGRAMME

The two extension agents began by explaining to local agricultural workers the benefits of fish farming. During the two years technichal advice on pond construction and pond management was given to 369 private fish farmers who built 481 ponds.

These ponds, which have a mean area of 105 m2 were stocked with 85,375 Tilapia nilotica fingerlings (558 kg) supplied by the newly built fish culture station. The fingerlings were sold at 100 FCFA per kg to the fish farmers, who stocked their ponds with 2 fingerlings per m2.

The mean nette production of these ponds is 16.13 kg per are per year. This production represents a cash value of approximately 30 US $ per year per fish culturist. This income is of considerable importance since per capita income is less than 125 US $ per year. The mean cost of pond construction is 17 US $. This is the cost of the labour. No matorials are involved.

The extension programme in Bouar thus represents a total capital investment of 8,177 US $ by pond owners, who produce 14,430 US $ worth of Tilapia per year (8,1 tons).

5. THE TECHNICHAL ANNEX

The sixty-odd pages of information contained in the annex form a unit which bridges a gap in our knowledge of African fish culture.

A detailed costing of the construction of a fingerling production station is presented (pp. 12–14); the operating costs (pp. 15–19) and the fish production (pp. 20–28) of the station over a two year period are detailed. A valid criticism may unfortunatly be made, that the station construction costs are slightly atypical due to the poor siting of the station.

The fish production of 156 private ponds (pp. 30–38), construction information for 172 private ponds (pp. 39–43) and details of private pond management and feeding (pp. 44–47) are given.

This data, which contains all the elements necessary for a comple cost-benefit study has already been put to use in planning the ‘new project’-a 3-year UNCDF financed prolongation of the present programme Some of the tables prepared for the UNCDF project feasability study are included (pp. 57–66).

6. DIFFICULTIES

Throughout my two years in Bouar the difficulties encounterod were continous. No vehicle was available for the last year. At the time of writing the 23 station labourers have not been paid for over six months. Houses and bridges were built by buying sacks of cement sac by sac with funds accruing from fingerling sales. Construction tools-wheelbarrows picks and shovels were so worn at my departune as to be almost useless. Internal politics created many problems among the staff. Alcololism and bad health among the extension agents also caused difficulties.

These problems originated almost entirely from the lack of couterpart funding as agreed in the project document.

ACKNOWLEDGEMENTS

I would like to sincerely thank the officials and workmen of the Station Piscicole de la Paya for their companionship and for sharing thei genial philosophies, in particular I wish to thank Mr. Jacques Bisset who built the fish station and Mr. Anselme Zaboua-Gendama who ran the extension programme.

I am very grateful for the latitude that my Project Manager, Mr. M. Vincke allowed me in my work. My thanks to Mr. J. Miller for his technichal advice, his optimism, and for always showing moral rigour. I wish to thank Mr. Z. Maletoungou for the lessons he taught me and Dr. E.P. Lindley, FAO, Bouar, for his advice and realism.
