Fish Behavior

Many fish, such as catfish, carp, and certain sharks, feed at night. Predatory fish hunt in low light, while nocturnal species use their strong sense of smell to locate food in the dark. Bottom-dwelling species also thrive at night. Night fishing is a great way to catch these fish effectively. For successful night fishing adventures, … Read more

Yes, fish commonly feed after rain. Rain alters barometric pressure and enhances water conditions, boosting oxygen levels. Runoff carries food sources, like worms, into the water, attracting fish. Surface-feeding species often search for food, especially after heavy rains. Fishing can be very productive during this time. The water quality also changes after rain. The oxygen … Read more

Fish eggs need fertilization to become embryos. Female fish release eggs into the water, where male fish fertilize them with sperm. This process is crucial for reproduction and occurs when fish reach sexual maturity. Fertilization commonly takes place in an aquatic environment during spawning. Several factors influence egg viability after fertilization. Water temperature plays a … Read more

Fish eat plastic, especially predatory species higher in the food chain. Research shows that a fish’s foraging strategy affects its likelihood of ingesting plastic. This behavior raises the risk of harmful effects, as these fish consume more plastic, impacting their health and the overall ecosystem. Research indicates that microplastics can accumulate in fish tissues, potentially … Read more

Yes, some fish eat coral. Corallivorous fishes, such as butterflyfishes and parrotfishes, feed on coral polyps. This activity may seem damaging, but it also plays an essential role in reef health. By eating dead or unhealthy coral, these fish promote new coral growth and help maintain ecological balance in coral reef ecosystems. Additionally, fish contribute … Read more

Most fish breathe using gills, which are specialized organs that extract oxygen from water. They take in water through their mouths. As the water moves over the gills, oxygen diffuses into the fish’s bloodstream. Fish do not have lungs; they depend on gills for their respiratory process in water. Unlike mammals, fish do not have … Read more

Yes, breastfeeding mothers can safely eat fish. Choose low-mercury options like salmon and shrimp. Limit high-mercury fish, such as swordfish and shark. Aim for 2-3 servings weekly from the “Best Choices.” Always select sushi from reputable sources. The health benefits of fish usually outweigh the risks with careful choices. Maternal diet varies among fish. Some … Read more

After a rainstorm, fish usually become more active. The rain adds oxygen to the water and changes barometric pressure. This encourages fish to leave their hiding spots and hunt for food. However, your fishing success can depend on the storm’s severity and water clarity. Use bright lures near structure for a better catch. Post-storm fishing … Read more

Feeder fish need a filter to keep water quality high and promote their health. A filter removes waste and adds oxygen to the water. Look for a small, effective, and affordable option. Good filtration supports a stable habitat and is vital for the survival of your feeder fish. Feeder fish, such as guppies or goldfish, … Read more

Coral reefs are vital food sources for fish. They support a rich marine life and provide shelter and breeding areas. About 25% of ocean fish species depend on healthy reefs for survival. The intricate structures of corals create habitats that help fish find food and reproduce effectively. Additionally, coral reefs play a vital role in … Read more
