What is metabolism in fish?

In fishes, the metabolism covers two processes: catabolism and anabolism. Catabolism is the process of breaking down metabolites to produce active energy, while anabolism uses those same products to build new body tissue for growth, maintenance, and reproduction.

What is metabolism in simple terms?

Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing.

What affects metabolism in fish?

The metabolism of fishes is profoundly affected by environmental factors such as temperature, oxygen concentration, and pH levels. Also, biotic elements, for instance, activity levels of species, have been suggested to affect the energy demand, driving their capacity to support environmental challenges.

How do you measure fish metabolism?

Temperature Effects

Animals get the energy to sustain life by oxidizing reduced carbon compounds in food, therefore metabolic rate can be measured experimentally by determining an animal’s rate of oxygen consumption (mg O2/kg body weight/hr).

What is metabolism function?

Metabolism is the process by which your body converts what you eat and drink into energy. … Even when you’re at rest, your body needs energy for all its “hidden” functions, such as breathing, circulating blood, adjusting hormone levels, and growing and repairing cells.

What are the 3 metabolic types?

The three main body types (or somatotypes) are endomorph, ectomorph and mesomorph. You’ll probably identify most with one of these, or you may see yourself reflected in a combination of two.

Is it good to have a high metabolism?

However, the word metabolism is often used interchangeably with metabolic rate, or the number of calories you burn. The higher it is, the more calories you burn and the easier it is to lose weight and keep it off. Having a high metabolism can also give you energy and make you feel better.

Can fish slow their metabolism?

The oxygen consumption, or metabolic rate, of a fish at rest tells us about the amount of energy that fish requires to simply stay alive. … Environmental conditions can also impair metabolism. When water oxygen levels are low, fish can struggle to quickly uptake oxygen from the water.

What do fish use for energy?


Animals cannot utilize/radiant energy from the sun. They get their needed energy from oxidation of the complex molecules which are eaten by the animal. The energy in feed is not available until the complex molecules are broken down to simpler molecules by digestion.

Do fish lower metabolism?

The metabolism can work at different speeds, depending on environmental conditions, and is controlled by hormones produced in the fish’s body. The metabolic rate can change with a variety of factors: Size – bigger fish have relatively slower metabolic rates.

How does age affect fish metabolism?

When fish are stressed their metabolic rates decrease. … When the fish’s size increases and the age increases to a stage of maturity, their growth rates will decrease slightly however will still be active when the environment for each species suggests the fish would be most active and have a high metabolic rate.

Why do fish prefer cold water?

They breathe the excess oxygen in the water. High barometric pressure forces more oxygen into the water than low barometric pressure. … Cold water has the ability to hold more oxygen than warm water. Hot summer temperatures can heat water so it won’t hold enough oxygen to maintain fish life.

Why does fish metabolism slow down in cold water?

Most fish species can’t survive in water that is too cold or too hot. When the water is too cold their metabolism becomes sluggish and they slow down. … This means they need more oxygen to support their faster metabolism. This may not be possible, though, because warm water tends to be oxygen poor.
