‘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 …

It’s online learning for PH aquaculture extension workers

Learning online isn’t just for students, it is also for the Philippines’ aquaculture extension workers who listened to lectures and practical sessions on milkfish and mangrove crab culture via an online platform. Forty-eight participants, mostly staff of the Bureau of Fisheries and Aquatic Resources (BFAR) from the different administrative regions, recently completed the FishKwela Training Course to enhance their skills on the hatchery production of milkfish and mangrove crab. The training course was the first technology and commodity-based online training course prepared by the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) in collaboration with the National Fisheries Research and Development Institute (NFRDI). Although SEAFDEC/AQD has been conducting online courses on fish health management and aquaculture nutrition since 2002, Caryl …

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 …

Seahorses get second life with SEAFDEC and NegOc islanders’ help

The coral reefs north of Negros Island are once more teeming with seahorses after a seven-year partnership between researchers and the local island community successfully protected and replenished their wild population. At Molocaboc Island in Sagay City, Negros Occidental, divers assisted in scientific surveys of seahorse populations, technicians maintained seahorse breeding facilities, the local government’s Bantay Dagat (sea patrol) enforced protection, and schools gladly embraced information and educations campaigns. The island is within the Sagay Marine Reserve, a marine protected area chosen as the project site of the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) to protect and revive the dwindling population of the tiger tail seahorse (Hippocampus comes).   During assessments done from 2012 to 2013, local divers …
