Top Winter-Feeding Tips for Pond Fish
When the temperatures drop and the pond starts to freeze, you may think that your fish will be okay since they can swim to the bottom and remain there until spring. However, just because they can survive doesn't mean they will thrive. In fact, without proper care, your fish will likely become sick or even die during the winter months.
Luckily, with a little bit of effort on your part, you can ensure that your fish stay healthy all winter long. Taking some preventative measures and being vigilant about potential problems can help your fish thrive even when the temperatures outside are plummeting.
This winter pond fish feeding guide will ensure that your fish get the nutrition they need to survive until springtime.

1. Poikilothermic and Homeothermic Animals-definitions.
Animals can inhabit different ecosystems. An essential factor in their survival success is their ability to adapt to changing environmental conditions while maintaining a stable internal environment. They are capable of regulating their internal environments thanks to physiological processes called homeostasis.
Dynamic homeostatic mechanisms regulate the animal body's essential parameters, such as glucose concentration or body temperature, to maintain stability while adjusting to changing external conditions.
Animals have two primary reactions to changing temperatures: poikilothermy and homeothermy.
Poikilothermic Animals lack the ability to generate heat and are known as "cold-blooded". The temperatures of these organisms fluctuate depending on weather conditions in the absence of any behavioural intervention. Examples of poikilotherms include "cold-blooded" animals such as most fish and amphibians.
Homeothermic Animals have specific abilities that allow them to keep their body temperature constant. They are called"warm-blooded" homeotherms, like birds or mammals, thanks to their particular physiological adaptations for regulating body temperatures.
2. Water temperatures and fish health.
Because pond fish are poikilothermic, pond water temperatures profoundly influence many aspects of their health. These include metabolic and digestion rates. Over the colder months, pond fish metabolism slows down and picks up as the temperatures start to rise in the spring.
A decrease in the water's temperature results in a reduction of appetite and a slowing down of fish metabolism. Whilst fish may still eat, they won't be able to digest the food properly, which can lead to health complications.
Different pieces have their minimum and maximum temperature ranges. Their health gets affected outside these ranges. If you have fish in your pond, monitoring the temperature of the water is extremely important to supply the best nutrition to them. So, if you don't have a pond thermometer, now is the time when you should get one.
3. How to feed pond fish in the winter.
As we move closer to winter, the cooler temperatures will cause pond fish to enter a state of semi-hibernation. This is a period of metabolic inactivity where their heart rate and breathing slow down significantly. As mentioned above, their metabolism will slow down to save energy and survive in cold water. Although they are not entirely inactive, their movements will be passive and may not be as responsive to their surroundings.
When the temperatures hit 10-15° Celsius, start mixing low-protein wheatgerm-based food with the standard food you use for feeding your pond fish. This type of food is much easier to digest and contains nutrition and immune system-boosting vitamins and minerals that pond fish need at lower temperatures. An additional advantage that it brings is the fact that it helps to keep nitrogenous waste to a minimum.
Gradually increase the wheatgerm food and decrease the high-protein food until the temperature drops below 10° Celsius. From this point onwards, stop the high-protein food and offer only wheatgerm-based food. Below this temperature, the fish will start to decrease interest in food and find shelter in the lower levels of the pond. Afterwards, they will cease coming for food, and feeding will stop until warmer weather occurs in the spring.
Please remember that if you continue feeding pond fish in winter, as in the summer and spring, it will lead to increased waste and elevated ammonia levels. On top, a slow metabolism will result in food not being digested, which subsequently can cause constipation and other serious health problems.
Refrain from being mistaken by the occasional appearance of fish at the surface during a random warm winter day, which we tend to get here in the south of England. Please do not be tempted to feed your fish, as it will be rather harmful.
And do not worry. Your pond fish have managed to build up enough fat reserves over the summer to survive colder months. Never forget that they live in a pond- an environment that naturally contains microscopic foodstuffs your fish can hunt.
4. Winter Pond Fish Feeding Guide. Summary.
Fish are cold-blooded creatures that cannot generate their body heat. In the winter, fish become less active when pond water temperatures drop. It means they don't need to eat as much because they use less energy. As a pond owner, you must remember that providing low-protein and wheatgerm-based nutrition is the best way to start going through seasonal temperature transitions.
Doing so will reward you with healthy and vibrant fish with solid immune systems equipped to handle the impending season. It will help the fish gain the right nutrients and body weight, allowing them to go through the cold winter months when they ultimately stop feeding.
