The macro mineral profile of four Nigerian species of earthworm; Hyperiodrilus africanus, Eudrilus
eugeniae, Libyodrilus violaceus and Alma millsoni was conducted. using the atomic absorption
spectrophotometer. Five macro minerals calcium, magnesium, potassium, sodium and phosphorus were
determined. Comparatively H. africanus recorded the highest mean Ca (0.494 ±0.038%) while A. millsoni
recorded the lowest (0.318±0.034%). Hyperiodrilus africanus also recorded the highest mean Mg
(0.154±0.015%) whereas L. violaceus recorded the lowest (0.118±0.017%). Alma millsoni recorded the highest
mean K (0.045±0.003% ) whereas H. africanus recorded the lowest (0.027±0.002%). The highest mean Na
(74.209±13.699 ppm) was recorded by A. millsoni while the lowest (19.813±2.087 ppm) was recorded by
H. africanus. Also A. millsoni recorded the highest mean P (0.701±0.022%) while H. africanus recorded the
lowest (0.456±0.034%). A significant difference was observed in the mean % Ca, % M g, % K, ppmNa and %
P between the four species of earthworms (p<0.01). The study revealed that these five macro minerals which
are requirements of animals w ere well represented and adequate in the earthworms. Therefore, the use of meal
prepared from these species as mineral supplement in fish diets could be encouraged.
