COUNTRY | RP NO. | RESULTS OBTAINED | INDUCED RESULTS | SUSTAINABILITY AND CONTINUITY OF EFFECTS | LIMITING FACTORS | CAUSES FOR EVENTUAL FAILURES |
IVC | 3 | C. nigrodigitatus fry available from state hatchery (high unit cost); on-growing production system available to lagoon farmers | Initial development of artisanal lagoon fish farming | Average, at least while assistance project is active | - High cost of fry - Centralised fry production - High initial investments - High production costs - Advanced technology - Limited market for highly -priced fish | Lack of fry/feeds Lack of loans/credit Technical support stops |
8 | Economically viable production system developed for extensive or semi-intensive farming of O. niloticus, based on locally available agro byproducts | Development of artisanal rural aquaculture | Average, at least while technical support remains available | - No credit system for small-scale farmers - Limited access to land for young people/women - Extension system inadequate | ||
NIR | 1 | Stocking of NIFFR small water bodies, using clupeid, tilapia and catfish | SWB production increased by more than 20% | Good | Govt funding | |
2 | Standardized technology for breeding out of season, C. nigrod, C. gariep, H. bidorsalis and hybrids Clarias × Heterobr. | Increased by availability of these species | Good | Govt funding | ||
3 | Tilapia/catfish cageculture | On-going research | Limited | Interbreeding in cages of O. niloticus/S. galilaeus | ||
5 | High quality feeds for tilapia and catfish | On-going research Feeds for farmers | Good | High cost of feeds | ||
6 | Selection of various species (Heterobranchus and hybrids) | On-going research New species for farmers | Good | Lack of credit for farmers High cost of feeds | ||
7 | Standardized integrated polyculture fish/broiler chickens introduced to farmers | Initial development integrated fish/an. husbandry farming | Limited | Lack of credit for farmers High cost of feeds | ||
8 | Identification of breeding/nursery grounds along entire coastline (6 major groups fish/FW prawn/shrimp) | Ab. 70% nat. demand fish for farmers non-covered by wild fry collections | Good | Lack adequate transport for fry Fry mortality | ||
CMR | Very few results from programme initiated in 1991 | |||||
PRC | 1 | C. gariepinus fry available from state farms to fish farmers; simple technology ready for private farmers | - Semi-profess. video film on simple technology available for training - Polyculture in state and private farms - increased prod./returns | Good, at least while assistance project was present | - No adequate facilities for artificial propagation - Bad water quality during rainy season - Limited number of protected ponds for fry production | |
2 | Stocking density of imported chicken over pond water for good organic fertilization was determined | - | Very limited | - Use of imported chicken breed; unreliable supply - Water management difficult in ponds arranged in series - Great losses of chicken feed in ponds | Problems with importation of one-day old chickens | |
3 | Standard norms available for feeding. Wheat bran to O. niloticus, on a sound economic basis with or without org. fertilization | - Increased fish food and economic benefits for state farms and private farmers using wheat bran | Good, at least while assistance project could ensure wheat bran availability | - | ||
4 | First indicative results obtained are encouraging | - | - | - Availability of cassava at research ponds limited | ||
CAF | 1 | Production of high quality feeds for tilapia/catfish | Initial development small scale commercial aquacult. in rural areas | Bad in absence of technical assistance | - High cost of pellets - Ltd market for fish due to low purchase power in rural areas | |
2 | Standardized technology for culture tilapia/African catfish | Increased fish prod. and soc. econ. benefits | Bad in absence of efficient extension | - Availability of fry especially African catfish | ||
3 | Standardized farming tilapia/catfish integrated with ducks, chickens, pigs | Increased fish/an. husbandry productions and soc.econ. benefits | Very limited | - Availability fish/livestock - Problems with pigs - Availability feeds for livestock | ||
4 | Standard technology for induced reprod., fry rearing and fingerling production of African catfish | Initial development of small-scale commercial aquaculture in rural areas | Very limited | - Lack pituitary glands - Lack Artemia cysts |
