How a fish gene fights deadly infections

Scientists found a protein in farmed tilapia that acts like an infection alarm. Called IRF5, it helps fish cells recognize threats like viruses and bacteria. When attackers show up, IRF5 gets more active in the fish’s head kidney—a place where immune cells are stored. This isn’t just some minor reac

Fish Vaccine That Triggers Cell Death to Stop Virus

Scientists studied a live fish vaccine that weakens a deadly virus in goldfish. The vaccine was made by changing the virus’s DNA. They found seven small changes, five missing pieces and one swapped section in important genes. One key change removed the start of a gene that normally stops cells from

Tilapia Muscle Cells: A Leap for Lab-Grown Fish Meat

Scientists have created a new type of muscle cell from a special kind of tilapia. They named it ONM, short for Oreochromis niloticus muscle. These cells were grown using a technique called explant. The cells did well in a special growth environment. They thrived in an L-15 medium with 5% fetal bovin

Why Fish Feed is Messing with Our Water Surveys

In the world of water studies, scientists often use environmental DNA (eDNA) to spot fish. But there's a problem: fish feed can fool these tests, making it seem like fish are present when they're not. This is a big issue, especially near fish farms, because it can give wrong results. Researchers to

How Fish Fight Germs: A Look at Tilapia's Tiny Defenders

Fish live in water. This water is full of germs. Fish are born ready to face these germs. They have a built-in defense system. This system is always on guard. It is called the innate immune system. One of its key weapons is tiny proteins called antimicrobial peptides, or AMPs. These AMPs help fish f

Turning Trash into Treasure: How Bugs Can Help Farms and Fish Tanks

Aquaculture is growing fast. This means more fish farms, and more fish waste. This waste is wet and hard to deal with. It costs a lot to get rid of. But what if this waste could be turned into something useful? Enter the black soldier fly. These bugs are like tiny recycling machines. They can eat o

Temperature Fluctuations and Fish Health: What's Happening to Hybrid Groupers?

Hybrid groupers are a big deal in the aquaculture industry, especially in Asia. But, climate change is causing temperature swings in the oceans. This is bad news for these fish, particularly the young ones. Scientists wanted to see how these temperature changes affect hybrid groupers. They looked at

Fish Gut Changes: How Heat Affects Olive Flounder

The olive flounder is a popular fish in East Asia. It is farmed for food. But, the fish faces a big problem. The water where it lives is getting warmer. This is due to climate change. Warmer water can make the fish sick. It can also slow down the fish's growth. Plus, it can change the tiny living th
