The FISH test, or fluorescence in situ hybridization, identifies chromosomal changes in cancer cells. It helps doctors find genetic abnormalities, classify cancers like breast cancer and leukemia, and customize treatments. FISH is essential for determining HER2 status in breast cancer and guiding targeted therapies for lung cancer and other types. Doctors often use FISH to … Read more

Fish survive winter under ice by slowing their metabolism. Their body temperature drops, leading to slower breathing and heart rates. Cold-blooded fish enter a resting state, conserving energy in deep water. They depend on omega-3 fatty acids for cell health and use enzymes to cope with the cold. Fish also utilize specific areas of the … Read more

To sustain fish stocks, we must reduce overfishing and bycatch with effective fisheries management. Global cooperation is essential to establish legal catch limits based on scientific evidence. Sustainable fishing practices protect ecosystems and support livelihoods, allowing fish populations to recover. Conservation efforts are crucial in this process. Conservation efforts play a crucial role in sustaining … Read more

Fish such as zebrafish and medaka can regenerate organs like fins, heart, and spinal cord after injury. This process includes dedifferentiation of nearby cells, enabling them to form new tissue. Unlike humans, fish regenerate without scar tissue. Studying these mechanisms could enhance human organ regeneration treatments in the future. Zebrafish are particularly notable for their … Read more

Saltwater fish survive in salty environments through osmoregulation. They drink seawater for hydration and use their kidneys and gills to excrete excess salt. This keeps them from becoming dehydrated and maintains their water balance. These adaptations help saltwater fish thrive where freshwater fish cannot. First, these fish actively drink seawater to replenish lost fluids. The … Read more

Fish live in saltwater by drinking seawater for hydration. They remove excess salt through special cells in their gills and via their kidneys. This process is known as osmoregulation. Species like salmon and bull sharks can adapt to both freshwater and saltwater environments, showcasing evolution and adaptation in marine life. Additionally, these fish have efficient … Read more

Freshwater fish thrive in rivers and lakes due to special adaptations. Their gills filter gases suited for low salt concentration. Unlike saltwater fish, they absorb water and retain salts using specialized kidneys. This process, called osmoregulation, helps them balance their internal salt levels in their ecosystems. Additionally, freshwater fish showcase remarkable behavioral adaptations. Many species, … Read more

Deep-sea fish live at the ocean’s bottom due to special adaptations. Their bodies are mostly water, preventing compression under pressure. They use trimethylamine N-oxide for pressure management. These fish do not have gas-filled swim bladders, which helps them thrive in high-pressure and low-oxygen environments. Additionally, many deep-sea fish have large, expandable bodies. This adaptation allows … Read more

Fish farms can reduce overfishing by controlling production and monitoring fish populations. This ensures sustainable practices and less pressure on wild fish. Aquaculture offers a reliable food source, enhances food security, creates economic opportunities, and helps prevent the overuse of wild species, supporting fish conservation efforts. Moreover, fish farms often implement practices that minimize environmental … Read more

Fish farming depletes ecosystems by using harmful chemicals like fertilizers and antibiotics. These chemicals pollute local waters and degrade water quality. Nutrients from fish waste can reduce oxygen levels. Overfishing for feed also threatens wild fish populations, harming marine habitats and reducing overall sustainability. To address these environmental impacts, sustainable solutions are essential. Implementing integrated … Read more
