The Effect of Mango Seed Extracts on the Nutritional Value of Fish Feed

Mango fruit is a type of fruit that are widely being used by the people of the world not just as a food but also as an ingredient in cosmetics and medicine. However, there are several scientific researches that found the whole mango fruit are not fully utilised where the skin and seed parts of the mango which are 35 to 60 percents of the mango are being discarded as waste. The purpose of this research is to use the seed part of the mango by extracting it and making the mango seed extraction as a raw material for fish feed. Extraction of the mango seed used soxhlet extractor with water as solvent. Data of the nutrient content of the altered feed were taken from proximate analysis of the feed. Feeding trial was conducted for 6 weeks in which the weight of the fish were sampled every week. The findings of this research provide scientific information on the nutritional value of the fish feed when mango seed extraction was added. From the proximate analysis result of the altered feed, the crude protein, crude fat, crude fibre, moisture and ash content increased as the mango seed extract were added, while carbohydrate content decrease. The fish that were fed with the altered feed had gained more weight than the fish that were fed with controlled feed. This project also aim to utilise the mango parts that are usually being discarded as waste as a raw material for feed
