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 …

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, …

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.

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 …
