‘Spaghetti’ fed to shrimp in bid to cut aquaculture cost

Humans are not the only ones who enjoy eating spaghetti—shrimp can, too. Researchers are using nutritious green “spaghetti algae” in fish and shrimp feeds as part of a broader move to bring down the cost of expensive aquafeeds which account for over half the expenses of farmers. “The ultimate aim of using spaghetti algae, or any other alternative ingredient, in aquafeed is to bring down the feed cost in aquaculture,” said Joseph Biñas, associate researcher and feed mill supervisor at the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) in Tigbauan, Iloilo. Biñas further said that, “The use of alternative ingredients, especially if these are locally available and sustainably produced, may considerably reduce the cost of formulated feeds.” Chaetomorpha linum, …

Agri-wastes eyed as cheap, eco-friendly source of fish feed

AFFORDABLE and sustainable feed ingredients for fish farmers are in the works as researchers continue to develop fish diet formulations using discarded agricultural wastes and byproducts. Dr. Frolan Aya, a scientist at the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD), and his colleagues examined agricultural wastes and byproducts for potential inclusion in diets formulated for omnivorous fish such as Nile tilapia (Oreochromis niloticus) in their study, “Potential use of agricultural wastes in aquafeed production.” Fruit peels, pulps or brans, seeds, bagasse (sugarcane residue), molasses, and okara (soybean curd residue) comprise 40 to 60 percent of wastes generated from major crop industries such as coconut, banana, pineapple, mango, citrus, and sugarcane. While these agri-wastes have found some use as organic …
