Shrimp birthing center ends unnecessary abortions

  Back in 2018, eggs from infected shrimp spawners would be promptly chlorinated and disposed – all 200,000 to 1 million of them per brood – to quell notorious pathogens that continue to devastate shrimp farms worldwide to the tune of billions of dollars yearly. This was the practice at the SEAFDEC/AQD Tiger Shrimp Spawner/Broodstock Facility in Iloilo, Philippines where incoming spawners are screened for pathogens, through polymerase chain reaction (PCR) tests, before allowing their eggs into a highly biosecure hatchery. Upon releasing their eggs, the spawners, are tested for the white spot syndrome virus (WSSV), monodon baculovirus (MBV), infectious hypodermal and hematopoietic necrosis virus (IHHNV), yellow head virus (YHV), acute hepatopancreatic necrosis disease (AHPND), and the parasite Enterocytozoon hepatopenaei (EHP).

‘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, …
