Plastic Aquaculture Tanks For Fish & Shellfish

These strong, durable plastic aquaculture tanks for fish rearing. Worldwide approximately only one-third of all fish farming takes place in natural habitats. It means most fish are bred under more or less controlled circumstances. There has been an upward trend in this sector because the costs of fishing in open water are increasing. Aquaculture is defined as underwater agriculture or the cultivation of aquatic plants, fish, molluscs and shellfish in a controlled or natural environment as well as the collective name for breeding salt and freshwater fish, shellfish and other living organisms in water like algae and samphire.

Aquaculture is predominantly the farming of fish for human consumption or ornamental purposes. More and more farmers are now choosing to use plastic tanks to meet the increasing demand to rear fish in a sustainable and cost-effective manner. We provide a range of plastic to suit your specific needs and budget.

Circular Water Tanks For Aquaculture

Enduramaxx circular water tanks for Aquaculture include open-top vertical tanks is constructed using rotationally moulded, food-grade, UV stabilised polyethene giving a seamless one-piece construction which is self-supporting and robust. From small quarantine tanks and laboratory test tanks, to early-stage rearing and tanks for bringing on fish Enduramaxx has a range of flat base tanks starting at 110 litres up to 25000 litres. Ideal as stock holding tanks, they are available in a variety of colours with a 5,000 litre option of a low profile tank which is 2600 mm in diameter and 1000 mm in height.

There has been a significant shift towards round tanks for fish rearing. Properly designed round tanks with a central drain, moderately sloped floor and proper inlet piping take advantage of gravitational and centrifugal forces to keep themselves clean. Enduramaxx manufactures low profile open top cone tanks mounted on galvanised steel frames with a 5 or 30° cone. The water moving in a circular flow will carry the solids to the central drain, from where they can be piped away for separation and re-use or disposal. With a properly designed inlet system, the oxygen rich water will provide just the right current for good muscle tone while distributing new water evenly throughout the tank.

This design improves space utilization inside the tank and allows the production of more pounds of fish per unit of water flow. The water flow direction can also be reversed periodically, helping to even outgrowth of the fish class by rearranging their feeding order. By avoiding the need to clean the tank floor of sediments both fish stress and labour costs are reduced. Once the fish faeces and uneaten feed are in a drain pipeline, it is relatively easy to separate these solids with either an efficient swirl separator (comparable in efficiency to a settling pond only using much less space) or a high-efficiency micro screen filter.

An oxygenated round tank aquaculture system can grow more pounds of fish with less feed, less water and less stress than a comparable area of raceways or ponds. The smooth tank surface of the rotationally moulded tanks further helps to eliminate disease vectors and skin abrasions, while providing a long-lasting, economical tank.

Conical Tanks For Aquaculture

Cone Tanks are available without frame if required. The 2,500 litre open top cone tank measures 2910 mm in diameter and 1770 mm in height when fitted in a frame (2600 mm x 960 mm high without a frame) and the 8,000 litre open top cone tank measures 2600 mm in diameter and 2551 mm in height when fitted in a frame. Both cone tanks are supplied with a 2” full drain outlet with other outlet sizes available. All our tanks are manufactured at our factory within the UK and come with a 10-year guarantee.

Bespoke and Square Tanks For Aquaculture

With larger radius corners and working heights to suit your needs, these robust yet highly polished tanks have the flexibility in purpose to fulfil the most demanding of roles. Available with or without feet, a variety of screen and outlet configurations and all manufactured to the highest quality.

Applications for these Plastic Aquaculture Tanks include.

  • Koi tanks
  • Fish Tanks
  • Fishponds

The installation of a fish tank in aquaculture

The installation of the fish tank needs very limited materials and tools. This allows for speedy installation of breeding tank. The operational costs are limited, because all breeding activities take place on and above ground level. The breeding tanks have a height of approximately 1.50 meters above ground level. These tanks are UV stabilised for outside installations.

Water Management & Fish Health

The main challenge of water management is keeping water consumption low, but without falling below an adequate level of water quality. The water quality must be good enough to make sure that your stock is healthy and your fish grow continuously. Water, as an important resource, needs to be handled with care. Excessive use of water will lead to high operating costs. Whilst ponds tend to lose water through seepage, recirculation systems require good filtration and aeration techniques as well as well-thought-out flow regimes. In general, the amount of water needed depends on the fish species and on the stock density.

Every fish farmer is interested in a healthy fish stock. The major reasons why health problems affect the fish farming business are the following:

  • Decreased stock output and revenue due to reduced fish health.
  • Diseases can spread and affect a larger part of your stock. Interaction with wild living fish is possible.
  • The water quality can deteriorate due to sick or dead fish and harm the rest of the stock not yet contaminated.
  • Insufficient water quality itself can cause stress and impede the healthy development of stock.

In order to avoid your stock being affected by the disease, medical treatment or vaccination can be used to a limited extent. Moreover, the important role played by water quality in keeping your stock healthy should not be underestimated. Water quality checks can be used as an instrument of control.
