Fish Behavior

Deep sea fish develop bulging eyes due to barotrauma. This condition happens when they are quickly brought to the surface, leading to a sudden change in pressure. The swim bladder expands, forcing the eyes outward. Symptoms include protruding eyes and a swollen stomach. Understanding barotrauma aids in explaining these effects in deep sea fish. Barotrauma … Read more

Deep sea fish can seem to explode when brought to the surface too quickly. Rapid pressure changes cause gases in their bodies to expand. Their bodies are adapted to high pressure, so changes can rupture cell membranes. This may lead to bulging eyes and leaking fluids, not actual explosions. Examples include fish with swimming bladders … Read more

Deep-sea fish can explode when brought to the surface too quickly. They are adapted to high pressure, and rapid ascent can cause their internal gases to expand rapidly. This expansion may lead to rupture. However, not all deep-sea fish have swim bladders, so the effects can vary by species and fishing practices. The risk of … Read more

Deep sea fish do not eat people. They live in deep waters that humans seldom visit. Species like anglerfish and goliath tigerfish are not dangerous to humans. These fish are mostly omnivores, feeding on small marine creatures. Under normal conditions, deep sea fish show no predatory behavior towards humans. Yet, some species exhibit cannibalistic behavior. … Read more

Dead flies, especially mayflies, often smell like dead fish. This odor comes from their decomposition when many die at once. Mayflies live for 24-48 hours and are usually seen in May and June. Although their scent is unpleasant, they are a sign of a healthy ecosystem. These stinky odors can attract other animals, including scavengers, … Read more

Salted minnows often catch more fish than live minnows. They remain firmer, last longer, and resist spoiling. Anglers frequently report higher success rates for trout when using salted minnows. This preservation method also simplifies bait preparation and enhances effectiveness, particularly in specific fishing conditions. The effectiveness of dalting minnows depends on various factors. Water temperature, … Read more

Dams block fish migration, impacting both juvenile and adult fish. Workers create fishways, like engineered fish ladders and salmon cannons, to help fish move past these obstacles. However, poorly designed structures can still hinder fish passage and raise mortality rates. Effective solutions are essential for improving fish behavior and survival. To enhance these efforts, dam … Read more

Cutthroat trout primarily eat small fish, crustaceans, and aquatic insects. As they grow, their diet shifts to include other fish. In coastal areas, they may also eat salmon eggs and sticklebacks. Their feeding habits change based on their age and the availability of prey in their freshwater habitats. Cannibalism often occurs in regions where the … Read more

Crayfish have an omnivorous diet. They eat both plants and animals, including aquatic plants and fish like unseasoned tuna. They also enjoy protein snacks. A proper tank setup is important. Crayfish may eat smaller fish, so consider feeding frequency and fish compatibility when choosing tank mates. When considering compatibility, crayfish can coexist with certain fish … Read more

Crappies do bite at night during ice fishing. The best times to fish for them are between midnight and 3 AM. Use glow jigs with small baits like waxworms or spikes. Focus on water depths of 10 to 20 feet. After dark, crappies move to shallower areas, boosting your chances for a successful catch. To … Read more
