Scientists wanted to understand how this fish handles saltwater, especially as it moves into
The western mosquitofish (Gambusia affinis) stands out in polluted waters. It often thrives where other fish cannot. Why does this happen? This question has been explored in a recent study. Scientists looked at how different fish handle selenium. Selenium is a tricky element. It can be useful

Yet, when it comes to understanding their senses, especially taste, there is a lot of mystery. Most studies on fish senses have focused on other spe
Fish can be very sensitive to changes in their environment. Two types of fish, Colossoma macropomum and Piaractus brachypomus, were put through a temperature test. This was to see how their bodies reacted to a sudden drop in temperature, followed by a return to normal. The fish were kept in water

A recent study explored how propylene glycol (PG) affects the growth and health of young striped catfish, also known as Pangasianodon hypophthalmus, when they are raised in chilly waters. The experiment lasted for 60 days and took place in a controlled aquaculture system. This system had a steady wa
The ocean is full of tiny particles that can mix with oil spills. This mix can create something called marine oil snow. This snow can sink and harm sea life. One big question is how fish waste, or fecal pellets, play a role in this process. The study looked at how different types of oil and fish
