Abstract

Proximate analyses, macro-, and micro-nutrient contents of the mature sea hare, Dolabella auricularia, and its egg strings were determined following the standard chemical analyses of the Association of Official Analytical Chemists (AOAC). Gravimetric method was used for moisture and ash content, Soxhlet for the crude fat, Macro Kjeldahl for the crude protein, UV-VIS for phosphorous and Atomic Absorption Spectrophotometer for Na, Ca, Mg Fe md Zn. The study showed that egg strings had higher concentration for moisture (93.32%), crude fat (2.01%), phosphorus (0.2266%), potassium (0.000869%), sodium (8.69%), magnesium (1.01%), iron (0.175%) and zinc (0.0282%). On the other hand, the mother sea hare showed higher concentration for ash content (39.78%), crude protein (33.25%) and calcium (8.77%). Based on the Recommended Energy and Nutrient Intakes (RENI), the egg strings are better alternative source of nutrients needed by our body.
