Many fish in local lakes are safe to eat, but the safety depends on your state health department’s guidelines. Consult the Michigan DNR’s Eat Safe Fish Guides for Lake St. Clair. Smaller fish usually have fewer contaminants. Always follow local consumption recommendations to ensure safety. The Michigan Department of Health and Human Services provides guidelines … Read more
Fish usually jump out of the water to catch insects that are on the surface. This behavior improves their feeding. Species like Florida mullet often jump during their spawning season. Fish also leap to escape predators or avoid disturbances from the environment. Silver carp may jump to feed on zooplankton, enhancing their survival. However, some … Read more
Fish eat microplastics, confusing them for food. Research indicates that around 386 fish species have ingested these plastic particles. Microplastics can enter their gastrointestinal tract and the food chain. This contamination is concerning, especially for estuarine fish and commercial fishery products. The shocking health risks for humans arise when we consume these fish. Chemicals in … Read more
Some fish-eating birds are carnivores. Ospreys and egrets are examples of these birds. They primarily hunt fish, which is their main food. The term “carnivore” means these birds eat meat. There is a specific term, “piscivorous,” that describes animals that mainly eat fish. Fish eating birds exhibit various hunting techniques. Some dive into water from … Read more
Fish are not dying in the oceans because of radiation from Fukushima. Radiation levels, such as cesium-134 and cesium-137, dilute in the Pacific Ocean. Studies show that fish near Japan may have higher cesium but pose no serious health risks to seafood. Other factors, like disease and environmental changes, also affect marine life. Studies have … Read more
Fish digestive systems are not filled with water. They expel excess water through their gills. Their intestines are important for digestion and nutrient absorption. Fish also absorb water through their skin and gills by osmosis. Many freshwater fish have a simpler digestive tract and lack a traditional stomach. Excretion mainly happens through kidneys. The stomach … Read more
Fish can be alive when caught. They may undergo processes like electrical stunning or suffocation. High-quality fish are processed quickly to prevent decay. Rigor mortis, which occurs after death, lasts one to two days. Prompt fish processing ensures freshness and meets standards for slaughter, like those set by the RSPCA. Humane practices in fishing aim … Read more
Fish at White Lake have died after recent water treatment. State officials report that an algae bloom, rather than alum treatment, led to fish mortality. As the algae die, they deplete oxygen, causing suffocation. The NC Division of Water Quality has stopped chemical treatments to evaluate water quality and the situation further. In White Lake, … Read more
Fish can be either osmoregulators or osmoconformers based on their environment. Marine fish typically act as osmoregulators, controlling their internal salt levels. In contrast, osmoconforming marine invertebrates match the salt concentration of their surroundings. Freshwater fish also regulate their ionic composition to adapt to their habitat. This ability to regulate water and salt balance is … Read more
Fish are classified as pets, especially for people with space limitations or allergies. They serve as companion animals and are popular choices for aquariums. However, fishkeeping involves responsibility. Though some see them as living ornaments, fish are living creatures that require proper care to thrive. Freshwater fish also fall under the pet category. Varieties such … Read more
