Results are shown on Tables (1, 2 and 3) of studied fish meat (Clarias sp.) using different types of drying methods. The chemical composition revealed no significant difference (P> 0.01) among the moisture, dry matter, and ash content, but fat and protein revealed recorded a significant difference (P<0.05). These results are in line with those reported by many authors. For example, Dirar (1993) studied the proximate composition of Hydrocynus sp. and recorded ( 34% moisture, 8.7% protein, 6.7% fat, 16.6% ash), and Ikeme (1991) who studied characterization of traditional smoked dried fish in Nigeria and found that the ranged of chemical composition parameter of protein (60-80%),fat(6- 15%), moisture (7-19%) and ash (5.4–15). The findings of this study are also in agreement with Ali et al.(1996) and Babiker and Dirar (1993) who studied the fermented and dried fish species of Sudan, Labeosp., Tilapia sp. and Clarias sp. and found, the chemical composition of moisture was ranged between 7.1- 9%, protein 55- 65%, fat 11.3-18.2% andash 12.5 - 22.9%. Table 1 shows that the highest average values of chemical composition parameters of dried fish were by using the open air drying method (5.95 % moisture, 94.05 % dry matter, 52.65 % crude protein, 7.95% fat, 8.1 % ash, and 25.35% nitrogen free extract N.F.E) followed by plastic sheet method (5.05% moisture, 94.95% dry matter, 59% crude protein, 6.8% fat, 8.85% ash and 20.45% N.F.E) and rabbit wire tent method ( 4.55% moisture, 95.45% dry matter, 61% crude protein, 7.1% fat, 8.55% ash and 18.05% N.F.E).This result is in agreement with the findings of Mahmoud (1977)who studied the meat quality of some common Nile fishes. The later author reported that the proximate composition of the fish species were in the range of 63.29-75.19%, 14.99-22.01%, 0.36-2.50%, and 0.45-1.94% for moisture, protein, fat, and ash, respectively. Chemical composition may vary widely, not only for fish of the same species, but also within an individual fish, according to age, sex, and environmental conditions (FAO, 2005). Sensory assessment as judged by the organoleptic test carried out on dried fish generally depends on the taste of panelists as presented in Table 2. The results show the color, texture, flavour and juiciness appears higher in plastic sheet than rabbit wire and open air methods. The effect of drying method on fish meat using plastic sheet was found to be better in terms of the overall acceptability (5.90) than chicken wire and open air methods which were recorded 5.73 and 5.36 respectively. This result is in agreement with other investigations (Verbeke, 2005; Greenhoff, 1994; McEwan, 1996). Most of these studies showed that, the consumers may have strong opinions and they usually find it difficult to explain in detail why they prefer one product to another. Results may be difficult to interpret; they also mentioned that, the descriptive sensory analysis carried out by trained sensory panels provides accurate and detailed description of the sensory properties of the products under study. The consumer acceptance or preference might be related to the sensory characteristics of products and preference mapping. It could be concluded that, the solar dryer tents covered by sheet (plastic and rabbit wire) in this study produce well-dried products in the terms in chemical, organoleptic indices and hygienic conditions
