‘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, …

Disease-afflicted PH seaweed farms see hope with help of scientists

Seaweed farming, a multi-million dollar export industry in the Philippines, is at the centerpiece of a worldwide effort by scientists to better address the outbreak of diseases and pests that are plaguing the farms. With an estimated 116,000 families in the country reliant on seaweed farming, SEAFDEC/AQD as part of the UK Research and Innovation (UKRI) – Global Challenge Research Fund (GCRF) GlobalSeaweedStar Project, is working to better understand outbreaks of “ice-ice” disease and epiphyte infestations in farms which have inflicted losses worth as much as 15 percent of the total seaweed production. According to Joseph Faisan, Jr. an associate researcher at SEAFDEC/AQD, “ice-ice” disease (IID) outbreaks are caused by extreme environmental conditions (temperature, salinity, pH, siltation) and are characterized …
