Filters are beneficial for any aquatic life.
Many people have a Bristlenose Catfish as a pet. One would not usually eat a Bristlenose Catfish. However, to cook this catfish successfully, one would need to cook it on a stove at about 250 degrees Fahrenheit for 25 minutes.
Before that question can be answered one would need to know what kind of catfish you are asking about. There are so many different species that are called "catfish" that it is impossible to make a generalisation.
yes
Yes, catfish fillets may contain small bones that need to be removed before cooking or eating.
Several species of Catfish are actually equipped with rudimentary lungs. These lungs allow these specific catfish to "gulp" air from the surface of the water and survive even if the water is not aerated.
Introducing a new species of catfish that filters water for microorganisms could significantly impact the pond ecosystem. It may reduce the population of microorganisms, potentially disrupting the food chain and affecting species that rely on them for sustenance. Additionally, the catfish might compete with native species for food and habitat, leading to ecological imbalances. Depending on its reproductive rate and adaptability, this new species could become invasive, further altering the ecosystem dynamics.
Range hoods may need replacement filters, but only every three or five years.
Well in some states you need a license but mostly you would need a license
