Why do fish growth at different rates?

Growth rates and size achieved by fish are highly flexible and subject to both genetic and environmental controls, so that size reached may vary with environmental variables such as water temperatures and food availability (both food abundance and prey types and sizes).

Do fish grow according to their tank size?

Fish grow to the size of their tank. There are a variety of factors that can limit a fish’s ability to grow properly but the size of the tank isn’t one of them. A fish that has not grown to its full size is said to be ‘stunted’.

Why is one fish bigger than the other?

Sickness – Another reason your fish may be larger than usual is disease. Even if they are cancerous, there are rarely treatments for fish. Overfeeding – Sometimes a fish may become fat or swollen as a result of his diet. Often, overfeeding or the wrong types of food can cause constipation and other digestive issues.

Why is one of my fish not growing?

Not giving your fish enough high-quality food is probably the most likely reason why they’re not growing properly. Remember, your fish need to get a lot of nutritious food that will help them grow into big and healthy fish.

What is growth rate in fish?

Growth curve is obtained when either length or weight of a fish is plotted against time periods. The curve obtained is sigmoid or S-shaped. This curve illustrates the rate of growth. If rate of growth is plotted against time, such curve is known as growth rate curve (Fig. 14.3a, b).

What is the growth pattern of a fish?

Fishes exhibit a ‘determinate’ type of growth in short-lived species of warmer regions and an ‘indeterminate’ type in long-lived species of colder regions. Growth is measured in units of length and weight and is best represented as the specific growth rate.

Can a fish explode?

Instead, they are filled mostly of water. Water, unlike air, is not very compressible, so this property keeps the pressure inside their bodies balanced with the pressure outside. Hence, when you bring them to the surface, they do not explode, or their organs do not rupture.

What factors will cause a fish to grow faster?

In Summary: What Makes a Fish Grow Faster?

• Regular water changes.
• Appropriate food.
• The right-sized aquarium.
• Appropriate decorations/plants.
• Water temperature.

Do all fish of the same species grow the same size?

Just like in humans, fish of the same species do not all grow at the same rates or achieve the same size as each other. Fish which have been bred in captivity using the same male and female for generations will often end up producing offspring considerably smaller than their wild cousins.

What is the relationship between age and growth in fish?

Both age and growth are closely related with one other. As the fish ages, it grows, but after attaining a particular size, growth stops. Age gives an idea about sexual maturity, spawning time, catchable size, growth rate and longevity. Knowledge of all these parameters is essential in fisheries production.

Why do fish grow slowly in the ocean?

Fish growth actually should be thought of as a reflection of food availability in relation to population size. A decrease in food base (prey) or an increase in predator fish abundance can lead to predator populations with slower growth. The converse is also true.

Will fish grow to the size of their tank?

You see these “tips” all the time, like small tanks are easier to take care of, or you have to have a bubbler to provide enough oxygen for the fish. One of the most pervasive, most widely believed fish tales is that fish will grow to the size of their tank. Is there any factual basis to this idea?
