Problems of Raw fish and Moist pellet
Concern of water environment pollution when supply diet⇒ Feed waste amount is higher than EP dietEasy to be infected because non-sterilized feedsLimiting supplementation of raw fishNutrient Imbalance ⇒ difficult to culture fish in nutritional method
![Page 44: Present status and future prospects of Korean and world ... · Dept. of Aquaculture / Feeds & Foods Nutrition Research Center (FFNRC), Pukyong Natl.

Merits of Formulated Practical feed
Possible to produce nutrient balanced feedsPossible to set up auto feeder system⇒ easy to manage and supply feeds, reduce labor cost
Easy to store (possible store for 3 months at room temperature)
Planned production possible
healthy culture, reduce the possible of disease infection
