What Are The Causes Of Fish Loss in Farm Ponds

In this article, we offer helpful information relating to the dangers for fishponds. This may come in very handy for fishpond owners, those of you that wish to own a pond, or for the ones that are just interested in fish. Though this particular study focuses only in Alabama, pond owners from other areas will also benefit a great deal because they will learn several fish farming principles such as causes of their uncommon deaths.

Most fish farmers face serious issues, for instance, decreasing fish numbers and diseases. Fish kills will result in a steady decrease in the quantity of fish obviously, and ultimately leading to a shortage of fish. Understanding the cause of how this happens and how to prepare for it is very important for pond owners. Therefore,

farm pond aeration is so critical.

Dissolved oxygen supplies are among the leading causes of fish loss. In order for your fish to thrive, your oxygen levels must be at or above the required levels. 

There are several ways to determine if oxygen depletion type of fish loss is occurring: Many of your fish will be swimming near the surface of the water in a desperate attempt to get oxygen. The larger fish will start dying off before the small ones. Often, the fish loss will begin in the early morning hours or early evening hours. This will happen rather quickly, generally within a few hours and the water will start to turn brown or develop a foul odor.

Oxygen depletion fish loss will normally occur because the phytoplankton or tiny green plants start dying, or the colder water from the deepest part of the pond merges with the surface water. A balanced pond, due to the phytoplankton, will have a greenish blue color. These plants oxygenate the pond. If there are long periods of time where the pond doesn’t get sun, the phytoplankton can die suddenly since they use more oxygen than they produce. When the phytoplankton dies, the fish consume the small amount of leftover oxygen and begin to die at a fast rate.

To prevent these dire oxygen level shortages caused by the dying phytoplankton, suitable fertilization should be used with your pond maintenance. But be careful, over-fertilizing may result in water that looks like green soup, with visibility only up to 2 inches as opposed to the desirable 18 inches of visibility. Excessive fertilization will also cause thick growth of phytoplankton. Whenever there is an overgrowth of any plants in the pond, there are many herbicides available that can be used to control the population. If you must use this method make sure you follow the instructions when using such pesticides as they can be harmful to your fish. An ideal combination for pond maintenance is fertilization with the use of a

pond aeration diffuser. If this is not possible because of no available electricity, a solar powered aeration pump is a great solution and economical as well. This will pump much needed air into the pond and will make a huge difference in the health of your fish.
