“…The outcome of vitamins in this study was closely consistent with the report made by Woodward (1994). Results obtained for rainbow trout are applicable to at least some other fin fishes (Dongmeza et al, 2009), including C. gariepinus. The vitamin and mineral contents in this study were adequate to support the growth and survival of C. gariepinus fingerlings.…”

Article HistoryIn order to evaluate cassava roots yield of two varieties at three harvesting dates and assess the effect of harvesting date on physico-chemical composition of roots and quality of gari and baton de manioc, a study was done. Cassava roots of a popular variety (local white) and the improved variety 8034 were harvested in small holder farmers' fields in the mono-modal humid forest zone and the bimodal humid forest zone of Cameroon. At harvest, the yield was evaluated, the physico-chemical composition of roots evaluated and a sensory test carried out on gari and baton de manioc after processing. Results showed that harvesting date has an effect on the cassava roots yield, for both local white and variety 8034. Cassava yield varied according to agro-ecological zones, with higher yield in the mono-modal humid forest zone than the bimodal humid forest zone. The nutrient content in cassava root varied with the variety and age of roots. There was an increase with the age of roots for K, P and dry matter content for the variety 8034. With the local white variety, there was an increase in total N and dry matter content. In contrary, there was a gradual decrease of percentage Mg, K, Na with the age of cassava roots for the variety 8034.Baton de manioc obtained from variety 8034 at 10-12 months and gari obtained from same variety were scored the highest global quality. Contribution/Originality:This study is one of very few studies which have investigated the right harvesting time and the best cassava variety to be used to obtain good cassava based-products.

“…The gross relationship, in the case study ponds, between the amount of green fodder applied (FM) and the net gain in grass carp biomass (FM) showed that 1 kg of grass carp was produced when approximately 68 kg of grass and leaf material were applied to the pond. Table 8.3 shows the gross chemical composition of some typical feeds used in the study area -data partly published by Dongmeza et al (2009). Most of the feeds applied here have high moisture and fiber content and relatively low protein content.…”

“…Most of the feeds applied here have high moisture and fiber content and relatively low protein content. Dongmeza et al (2009) found that the general quality of the applied feeds was rather poor; however, certain feeds such as cassava and mulberry leaves contained high crude protein contents (20-30 %) ), though high protein content does not necessarily indicate a better quality diet, as demonstrated by authors such as Shireman et al (1978) and Tan (1970). Low fiber content is also an important factor, and the digestibility coefficients for crude protein and gross energy; for example, decline significantly with increased fiber content of the plant feed (Hajra et al 1987).…”
