Fish live in frozen lakes by using the liquid water below the ice. Ice provides insulation, keeping the water’s temperature stable. Fish enter a torpor state to lower their metabolism. They adapt to the cold by surviving with reduced oxygen levels, which remain in deep water habitats during winter. This helps ensure fish survival in … Read more

Farmed fish receive treatments like vaccines and antibiotics to maintain health. They often lack legal protections and face welfare issues. Aquaculture practices focus on infection control and proper diet. Despite these measures, farmed fish can still spread diseases to wild populations, impacting their health. Cruelty is another serious issue. Fish often experience stress from confinement … Read more

Farmed fish are usually killed through methods like asphyxiation, carbon dioxide exposure, and electric stunning. Some practices, like gilling without stunning, cause suffering. Humane methods aim to reduce stress and pain. The best approaches involve quick and lethal techniques to ensure fish welfare during slaughter. Welfare standards for farmed fish emphasize the importance of treating … Read more

Farmed fish are harvested using methods like large nets or vacuum systems. After catching, fish are cleaned, iced, and sent to market. Fish farming, or pisciculture, takes place in controlled environments. This improves breeding and harvesting efficiency while minimizing the environmental impact. Another important practice is the use of recirculating aquaculture systems (RAS). RAS reuses … Read more

Farmed fish are caught using methods designed for aquaculture. Common methods include netting in ponds, tanks, or net pens. Farmers use nets and traps to capture fish efficiently. They also provide fish with specific diets to meet their dietary needs, which enhances growth and health before the harvest. Seafood quality is another essential aspect of … Read more

Deep sea fish avoid crushing by having internal pressure equal to their environment. They do not have swim bladders or air pockets, which protects them from external pressure. Additionally, compounds called piezolytes help keep their cellular membranes stable, enabling these marine organisms to thrive in extreme conditions. Additionally, deep sea fish possess specialized swim bladders … Read more

Deep-sea fish are caught using baited traps, static nets, pelagic trawling, and bottom trawling. Anglers also use spear fishing and rod and reel methods. Common species include Swordfish, Tilefish, and Queen Snapper. These fish are often found at depths greater than 2000 meters, where they move vertically during the day. Another method is deep-drop fishing, … Read more

Deep-sea fish have special adaptations for survival. They use bioluminescence to attract prey and mates. Their bodies contain TMAO to resist high pressure. Many species are transparent or red for camouflage. These traits help them thrive in low-light, low-oxygen environments, highlighting their unique physiological and behavioral strategies. Additionally, many deep sea fish have developed large, … Read more

Fish have gills that allow them to absorb oxygen from water and release carbon dioxide efficiently. In contrast, lizards possess lungs for breathing oxygen from the air. This difference highlights how their respiratory systems adapt to their aquatic and terrestrial habitats, reflecting distinct anatomical structures and evolutionary traits. In contrast, lizards possess lungs for breathing … Read more

Atlantic salmon differ from other species, such as Pacific salmon, in taste, texture, and habitat. They have a light pink color and mild flavor, while Pacific salmon features a richer color and firmer flesh. Atlantic salmon are anadromous, living in both freshwater and saltwater. Wild populations are currently protected due to overfishing concerns. In addition, … Read more
