The question of the quantity of fish a pond can take is vital if you are looking to successfully rear your fish.

In nature, overpopulation is bad, it gives rise to all sorts of problems with disastrous consequences.

Imagine having 20 grown-up men in a small one-room apartment. There will be an extreme situation of survival of the fittest.

Everything will be a competition or battle, and the weakest will suffer or even die off.

The same applied to overstocking a pond with fish, there will be a struggle for survival and only the biggest and strongest will feed well and thrive.

Matter of fact, you may have to deal with incidences of cannibalism.

This will cause you to run at a loss, and possibly put you out of business.

Therefore, the question of the quantity of fish pond can take should be posed first before you start stocking.

You shouldn’t just use instincts or try to maximise space, it can lead to unfavourable consequences that will cost you your profit if not your farm.

Fish pond carrying capacity

In fish farming, every fish pond has a carrying capacity, that is there is a maximum weight of fish a pond can carry.

Anything exceeding this carrying capacity will cause the fish to stop growing as they should.

This means the weight of the fish must not exceed the pond’s carrying capacity.

For instance, if a pond has a volume of 1000 litres of water, and we have a standard of 10 litres to 1 fish of 1kg, it means the pond can carry only 100kg fish or 100 fish.

Now with other factors being convenient, 100kg of fish can thrive well in this assumed pond of 1000 litres based on the given standard (10 litres to 1kg).

This means you must not stock the pond with a number of fish that exceeds or will come to exceed 100 kg, if not, the fish stock won’t thrive well.

For the sake of clarity, a fry can’t be up to 1kg, but a table size fish can reach and even exceed 1kg.

So, for the pond of 1000 litres of water discussed above, your fish weight upon maturation should not exceed 1kg.

And the total weight of your stock upon maturation shouldn’t exceed 100kg.

If the weight of fish exceeds the carrying capacity, it means some of the fish have to die.

Carrying capacity is not measured by the dimensions of a fish pond but by the volume of water, it can take which, in turn, determines the number of fish a pond can take.

It is advisable to get bigger ponds for better results.

What to consider before stocking your pond

Here are some tips that should guide you before you can calculate the stocking density of the fish pond with accordance to the following formulas for you to understand the volume of fish to stock in your fish pond.

Knowing the quantity of fish a pond can take is important but there are a number of items to be put into consideration before stocking your pond or before you can deduce the stocking density of your fish pond.

These items include the following:

Finance

Financial power is key to smoothly nurturing your stock of fish into maturing.

Feeding takes the largest chunk of finances used in fish farming.

And trying to cut corners in purchasing feed and feeding your fish will only end up in disaster.

Poorly fed fish won’t grow well. Therefore, stock your pond according to what you can afford, and endeavor to market your stock days before running out of feed.

Personnel

This involves the manpower or workers handling the affairs of your fish farm.

Personnel given the task to manage the farm should be skilled or have the know-how and should maintain discipline in carrying out their duties.

Power

You need the power to pump water into your fish pond or change the water in your pond.

You may use a gasoline generator, solar, or government power supply depending on your prevailing situation.

Water management

This concerns the availability of water. And not just any type of water but clean and safe water for the fish to thrive well.

Water management involves a steady supply of water and routine change of water when it gets messy.

Water management must be carried out effectively in a fish farm as it determines the well-being of your stock.

Calculation of stocking density

The quantity of fish a pond can take can be calculated and should be calculated.

This is to ensure proper stocking or to avoid high stocking density.

However, the calculation of stocking density varies, it depends on the type of pond used.

Here is how to calculate the quantity of fish a pond can a pond can take (using the following calculation parameters).

Concrete Pond: Length x Breadth x Height x 5/3 [Measurement done in Feet]
Earthen Ponds: Length x Breadth x Height x 2/5 [Measurement in Feet]
Mobile fish Pond: Length x Breadth x Height x 5/3 [Measurement done in Feet]
Tanks: For tanks, I would advise you use use a standard of 50  litres per fish.

The FAO stocking density standard of 10 litres of water to 1 fish has proven to be detrimental.

Avoid using the FAO stocking density because there have been complaints about it.

Summary

Being conscious of the quantity of fish a pond can take and strictly adhering will greatly help your fish farming venture and save you from loss.

One of the reasons fish farms fail is due to overstocking or excessive stocking density.

You have to put stocking density into consideration as you construct a fish pond or buy a mobile fish pond.

And you should get a big pond if you are looking to rear a significant number of fish.

Note that the pond is not filled with water to the brim, hence, the need for a big pond.
