Nutritional evaluation of some small coastal fish in Sri Lanka
Small pelagic fish play a very important role in human nutrition and health. Lipids of these fish differ remarkably from plant and other animal lipids. The aim of the study was to describe the proximate composition of thirty-three small pelagic fish species commonly available in Sri Lanka. Fish species were collected from Negombo and Chillaw fish landing sites and subjected to analysis for moisture, ash, protein and total lipid content. Tiger tooth croaker (Otolithus ruber) was found to have the highest moisture percentage (80.0%) followed by Clarias sp. (78.9%), Indian anchovy (Steloporus indicus) and Comerson's anchovy (Stelophorus commersonii), (78%). The lowest percentage of moisture, 69.4%, was recorded in white sardinella (Sardinella albella). Indian ilisha (Ilisha melastoma) was found to have the highest amount of ash (10.1%) followed by Otolithus sp. (8%) and big-eye barracuda contained the least amount (2.5%). Carassius Carassius, pick handle barracuda (Sphyraena jello) and Indian mackerel (Rastrelliger kanagurta) contained higher amounts of protein, 24.3, 20.6 and 19.2% respectively. The lowest protein content (10.1%) was found in Indian scad (Decapterus russelli). The protein content of the fish was in the range of 13-15%. The results revealed that the small fish are moderate protein sources. The total lipid content varied between 0.6-8%. White sardinella recorded the highest percentage of lipid (8%) where tiger tooth croaker contained the lowest percentage (0.6 %). The study showed high fatty species to contain low amount of moisture and vice versa establishing an inverse relation between fat and moisture quantitatively.
