Nutritional and shelf-life studies of dry smoked and gamma irradiated shrimps (Penaeus notialis) from three different water sources in Ghana

Figures & data

Table 1. Treatment means for the effect of dose obtained from a multifactor ANOVA of physicochemical indices of shrimps

Doses (kGy)	Treatment means ± standard error
	Crude protein	Ash	Fat	Moisture
0	34.35 ± 1.30^b	15.42 ± 0.09^d	1.72 ± 0.01^d	12.92 ± 0.06^d
4	29.00 ± 1.30^a	14.94 ± 0.09^c	1.02 ± 0.01^c	10.32 ± 0.06^c
8	30.06 ± 1.30^a	14.31 ± 0.09^b	0.95 ± 0.01^b	9.73 ± 0.06^b
10	27.40 ± 1.30^a	13.80 ± 0.09^a	0.90 ± 0.01^a	9.36 ± 0.06^a

Means within each column with different letters are significantly different (p ≤ 0.05).

Lagoon	30.26 ± 1.13^b	13.74 ± 0.08^b	0.85 ± 0.01^b	9.81 ± 0.05^b
River	34.42 ± 1.13^c	11.85 ± 0.08^a	0.76 ± 0.01^a	9.22 ± 0.05^a
Sea	25.93 ± 1.13^a	18.25 ± 0.08^c	1.83 ± 0.01^c	12.72 ± 0.05^c

Means within each column with different letters are significantly different (p ≤ 0.05).

Table 3. Treatment means for the effect of months (initially and 4th month) obtained from a multifactor ANOVA of physicochemical indices of shrimps

Month	Treatment means ± standard error
	Crude protein	Ash	Fat	Moisture
Initially	28.41 ± 0.92^a	13.95 ± 0.06^a	1.25 ± 0.01^b	11.10 ± 0.04^b
