How quickly do carp grow?
It is only in warmer countries than here, or if the carp are grown indoors with the water being heated and constantly maintained, that they reach their maximum potential.

What do baby carp eat?

What do koi babies do?
Koi are notorious for feeding on their young, so moving breeding fish into a separate aquarium for spawning is critical. Baby koi born in the koi pond are fish bait, literally. Moving the adult fish out of the spawning tank quickly after spawning is complete and before the eggs hatch is also crucial.
What happens after fish lay eggs?
The eggs develop and hatch into larvae (baby fish) without any help from the parents. Most larvae are eaten by other creatures, but a few survive to become adults. Some fish, such as the bullhead, look after their eggs or young. This improves the chances of the babies surviving, so fewer eggs are laid.
What water temperature do fish spawn?
Water temperature: Fish spawning times will vary for different species and can also vary depending on the size and depth of a waterway. As an example, largemouth bass prefer water temperatures between 60-75 degrees for spawning, while bluegill spawn when water temperatures are in the 75-85-degree range.
Why are my grass carp dying?
Deeper areas naturally have little dissolved oxygen during the summer. Fish can’t live in this portion of the pond at that time. When the “turnover” or mixing happens quickly, such as a sudden, heavy downpour, it results in much less oxygen throughout the entire pond and causes fish to die.
Why are my koi dying?
Most of the time, death in koi carp is caused by poor water quality. Making sure you have proper filtration, regular testing and maintenance will all contribute to the quality of your pond water, and therefore the health of your fish.

Do koi hibernate?
Well, Koi fish actually go into a certain type of hibernation, called torpor, that allows the animal (or in this case, fish) to regulate their body temperature to acclimate to the air or water temperature. This is what allows them to survive when it gets below freezing.
