Benefits of Constructing a Fish Pond with Tarpaulin and Woods

Let us lay more emphasis on the benefits of constructing the fish pond with tarpaulin and woods.

Constructing fish pond with tarpaulin and wood is cheaper than the others of the same size although it is not as strong as others. It is also a very good one to use on a land that is not a permanent site.

The disadvantage however is that thieves can easily pull down the pond in an attempt to poach into the fish farm. Also, if adequate care is not taken in making sure that the supporting wood is well solidified, flood and wind can easily pull down the wooden structure.

In the way of making a tarpaulin pond for catfish cultivation there are some things that must be noticed, among others, the population of catfish and the width of the tarpaulin pond.

The exact standard for 100 catfish wide the size of the tarpaulin pool needed is (Length 2m x Width 1m x Height 0.6m). If you want to develop catfish in the number of more multiplied by the length and width of the pool.

Tarpaulin ponds for catfish farming can be made using wood, soil, or brick. For ponds with soil can by digging a hole in the ground then covered with a tarpaulin. While ponds with wooden framework or brickwork can be made above ground level.

Some things to consider before spreading the seeds into the pond should be the tarpaulin pond of catfish seedlings in content with water that is rich in algae / plankton (green water biota) as the main food source of catfish seedlings.

In order for catfish to grow more quickly should catfish seedlings are also given a special pallet catfish as much as 2 times a day. In addition to pellets, can also be given natural foods such as snails, snails mas, shellfish, termites and others.

The pool water is also obliged to be replaced, so as not to make the water quality becomes bad and smelly. Poor water quality will affect the emergence of various diseases.

Alternative water change is done by removing 10-30% of the pond water, and adding the same amount of water to the discharged once every week or every 2 weeks.

When the age of catfish reaches 1 month, then the selection and separation of catfish based on quality and size should be done. It aims to grow catfish to be equally good in terms of size and quality of catfish.

 But first let us understand what a tarpaulin is:

What is Tarpaulin?

Tarpaulin is a strong and thick sheet of polyethylene. It can also be made from other substances. It is very resistant, water proof and adjustable, and used to cover agriculture products and other things. It is commonly known as ‘Tripaal’ in Hindi.

Quality of tarpaulin depends on different manufacturers, and its quality is measured by GSM (Gram Per Square Metre). A tarpaulin tank of high volume is very necessary for commercial fish farming.

However, 200 – 520 GSM tarpaulin sheets can be used for one to two season crop for making small tarpaulin tank if maintained and managed properly.

Now considering the following:

  • A commercial tarpaulin fish tank should be made of a minimum 500 GSM tarpaulin sheet.
  • Frame of tank should be made of iron mesh. There is always a possibility of blast of cement tank.

That then brings us to the benefits attached to using a tarpaulin fish pond:

Benefits Tarpaulin Fish Pond

The benefits of fish tank made by tarpaulin are:

  • It is flexible, water can adjust itself inside tank.
  • Management of ammonia is easy compare to cement tank.
  • Very less amount of water needs to be rotated/replaced as compare to RAS.
  • Easy to develop bioflock.
  • Easy to harvest fish.
  • It is transferable.

Ideal Structure of Tarpaulin Fish Pond

Size and the shape of a tank can affect the overall growth and production of fish in a tank. Round shaped Tanks are more efficient than square or other shaped Tanks.

A tank with radius of 2 metre provides required space for… fish. Other benefits are as fallows:

  • Bit of fish accumulates near the centre of tank at bottom place where outlet has been created.

Procedure of Establishing Tank

2.1 Required Materials/Resources

  • Testing kits for- Ammonia metre, PH metre, thermametre.
  • Tarpaulin sheet of minimum 500 GSM.
  • Aerator.

2.2 Selection of Site

Plain land should be preferred over uneven land. Availability of fresh water is the first criteria.

2.3 Establishing Fish Tank

2.3.1 Marking for Circle

  • After collecting all required things take a measuring tape.
  • Mark a point at any where in land as Tank’s centre.
  • Place the starting point of the tape and make a circle around it with 2 metre’s radius.
  • Mark all the measuring with any substance like lime.

2.3.2 Establishing Iron Frame

  • Completely fill the circle with single layer of bricks using sand and cement.
  • Make circular fence around the periphery of the circle using iron mesh.

2.3.3 Placing Tarpaulin Sheet

  • Tarpaulin sheet is fixed according to established iron mesh.
  • Make an out let at the centre of tank connecting it with aerator.
  • Firmly fix the sheet with mesh.

6 Mistakes to Avoid when using Tarpaulin Fish Ponds for Profitable Fish Farming

If you are thinking of buying or using mobile tarpaulin fish pond for your fishes, I would give you a go ahead but here is some advice for you (some 6 mistakes you should avoid)

1.  Insist on “reinforced tarpaulin”

 This is the most important factor that you must put into consideration before you decide to use mobile tarpaulin fish pond for your farm.

There are different types of tarpaulin that have been in the market.
There are the normal ones used in making tents (like semi-permanent church/fellowship and other event centres), there are the ones used in making canopies (that people rent for traditional marriages) and there
even other types used in making car parks.

They are all of different qualities and serve different purposes, and the one used for fish pond is the “reinforced tarpaulin”. Fish ponds that are made with the other type of tarpaulin usually break in two or three months, or even earlier.

Simply put, if it is not reinforced tarpaulin, don’t buy!

You can go online on Google and search for “reinforced tarpaulin fish pond”, and then find some sellers.
However, since it is still possible for desperate sellers to brandish their products as “reinforced tarpaulin”, I will endeavour to recommend my own trusted online seller at the end of this piece.

2.  Avoid Buying from Online Marketplaces

Online market places may be good for other products like clothing, electronics, furniture, etc., but definitely not for collapsible mobile tarpaulin fish pond because of the ease of buying substandard (the unreinforced quality).

Most of the complaints about fake tarpaulin ponds that I have received from members of various fish farming cooperatives that I have coached are from people who bought their tarpaulin fish ponds from online marketplaces like Jiji, Nairaland, Jumia, Konga, etc.

It is usually easy to create account and join those marketplaces, so they can be crowded with every tom, dick and harry.

3. Buy the fish pond tarpaulin and set it up yourself (it is way cheaper this way)

Now this may sound a bit more stressful but what you get to save at the end is worth it.

I am a DIY (Do It Yourself) person and I have never bought tarpaulin fish pond from vendors who have to transport both themselves, the tarpaulins and the galvanized pipes (or wood, bamboo or other materials used that can be used for the tarpaulin fish pond framework) all the way down to my location to set everything up. There is no need for such unnecessary cost and logistics.

From the experience of a few persons I know that initially tried patronizing such vendors in the past, you get to save roughly N10,000 to N15,000 per pond if you buy the tarpaulins and set them up yourself.

What I would recommend is that you buy the tarpaulins (this can be done online on Benuwatts website) and engage an average road-side welder (or carpenter) around you to set them up for you.

4.  Buy more and try to negotiate for discount if you are buying in bulk

When buying up to five or more fish pond tarpaulins, it is good practice to ask for a discount. From my experience with Benuwatts, they almost always gave some sort of discount or bonus whenever we (I
and my cooperative members) bought in bulk.

If you intend to really raise fishes, you will need more than one tarpaulin pond after all, so why not buy them at once and negotiate some cut. Even if it is 1 per cent discount, it is something.

5.  Smaller can be better

If for example, you wish to raise about 1000 catfish to maturity and need tarpaulin fish pond for that, you can go for a tarpaulin that has the capacity to house 1000 table-size fishes.

However, it is always advisable to have two or even three ponds when starting out in order to have the opportunity to sort (or separate) your fishes on the basis of their sizes.

Else the shoot outs (the fishes that quickly grow bigger than others) will begin to feed on the others.

So, instead of buying just one large 1000-capacity tarpaulin to house all your fishes from fingerlings/juvenile to table size (adult size), you should buy two or three smaller tarpaulins so that you can sort into the other tarpaulin ponds as the fingerlings/juveniles grow.

Mind you, the more space the fishes have to swim around, the better the results you will get in terms of size and weight of the fishes within a set period of time.

 6. Buy from a trusted supplier

The thing is that, of recent (from around late 2016), lots of people have been flooding the market with fake tarpaulin ponds, and with that have come lots of complaints about mobile tarpaulin ponds (hence the disadvantage).

There are several people who have complained of how they bought tarpaulin ponds from several vendors only for the ponds to break up in about two months.

If you truly want to use mobile tarpaulin pond and enjoy it, do yourself some favour and avoid fakes.
