Being a scientist was never part of his career plan, but this young researcher is already making waves in aquaculture research with his award-winning study on the giant grouper, a “threatened” fish locally known as lapu-lapu. Peter Palma and his team recently bagged the prestigious Dr. Elvira O. Tan Awards – Outstanding Published Paper in the Aquatic Science Category for their paper that studied the sexual development of the hermaphrodite fish and debunked presumed norms on the origin of the male giant grouper. Their paper titled “Reproductive development of the threatened giant grouper Epinephelus lanceolatus,” published in the Aquaculture Journal last July 2019, presented evidence that male giant grouper do not need to pass through a female stage at an earlier …

In a bid to produce more of this aquaculture superfood and as efficiently as possible, Mandario recently established the optimal light conditions for the polychaete hatchery where the mudworm eggs are hatched, and larvae are nursed. The finding is important because the 10,000 species of polychaetes have varying responses to light at their different life stages.

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 …

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 …

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 …
