[005]. The subject matter discussed in the background section should
not be assumed to be prior art merely as a result of its mention in the
background section. Similarly, a problem mentioned in the
background section or associated with the subject matter of the
background section should not be assumed to have been previously
recognized in the prior art. The subject matter in the background
section merely represents different approaches, which in-and-of
themselves may also be inventions.
[006]. As fishes are major source of protein, the growth in the fish farming
sector mainly comes from the freshwater aquaculture and about 12.8 % of
total animal protein consumed in India comes from freshwater fish.
[007]. Recirculation aquaculture is essentially a technology for farming fish
or other aquatic organisms by reusing the water in the production. The
technology is based on the use of mechanical and biological filters, and
the method can in principle be used for any species grown in aquaculture
such as fish, shrimps, clams, etc.
[008]. Recirculation technology is however primarily used in fish farming,
and this guide is aimed at people working in this field of aquaculture.
Recirculation is growing rapidly in many areas of the fish farming sector,
and systems are deployed in production units that vary from huge plants
generating many tons of fish per year for consumption to small
sophisticated systems used for restocking or to save endangered species.

[0034]. An Fish Culture Tank Integrated With a Novel Water
Recirculating System is disclosed.
[0035]. RS operate by filtering water from the fish tanks so it can
be reused within the tank. This dramatically reduces the amount of
contaminated water and also helps in solids removal, ammonia
removal, C02 removal and aeration Recirculation systems (RS)
represent a new and unique way to farm fish. Instead of the
traditional method of growing fish outdoors in open ponds and
raceways, this system rears fish at high densities, in indoor tanks
with a "controlled" environment. Recirculating systems filter and
clean the water for recycling back through fish culture tanks. New
water is added to the tanks only to make up for splash out and
evaporation and for that used to flush out waste materials. There
are other following advantages of self-made recirculating system.
[0036]. Principle drawing of a recirculation system. The basic
water treatment system consists of mechanical filtration, biological
treatment and aeration/stripping, filter bed with pebbles. Further
installations, such as oxygen enrichment or UV disinfection, can be
added depending on the requirements. Several other facilities can
be added, such as oxygenation with pure oxygen, ultraviolet light
or ozone disinfection, automatic pH regulation, heat exchanging,
denitrification, etc. depending on the exact requirements..
[0037]. In a recirculation system, a high utilization rate of the feed
is beneficial as this will minimize the amount of excretion products
thus lowering the impact on the water treatment system.
[0038]. C02 is removed by aeration of the water, whereby
degassing takes place. Biofilters used in recirculation systems can
be designed as fixed bed filters or moving bed filters. All biofilters
used in recirculation will work as submerged units under water. In
the fixed bed filter, the plastic media is fixed and not moving. The
water runs through the media as a laminar flow to make contact
with the bacterial film. In the moving bed filter, the plastic media is
moving around in the water inside the biofilter by a current created
by pumping in air.
[0039]. Before the water runs back to the fish tanks accumulated
gases, which are detrimental to the fish, must be removed. This
degassing process is carried out by aeration of the water, and the
method is often referred to as stripping.
[0040]. The aeration process of the water, which is the same
physical process as degassing or stripping, will add some oxygen to
the water through simple exchange between the gases in the water
and the gases in the air depending on the saturation level of the
oxygen in the water.
[0041]. Maintaining an optimal water temperature in the culture
system is most important as the growth rate of the fish is directly
related to the water temperature.
[0042]. In an indoor recirculation system the heat will slowly
build up in the water, because energy in the form of heat is released
from the fish metabolism and the bacterial activity in the biofilter.
Heat from friction in the pumps and the use of other installations
will also accumulate.
[0043]. Different types of pumps are used for circulating the
process water in the system. Pumping normally requires a
substantial amount of electricity, and low lifting heights and
efficient and correctly installed pumps are important to keep
running costs at a minimum.
[0044]. The lifting of water should preferably occur only once in
the system, whereby the water runs by gravity all the way through
the system back to the pump sump.
[0045]. Pumps are most often positioned in front of the biofilter
system and the degasser as the water preparation process starts here.
In any case, pumps should be placed after the mechanical filtration
to avoid breaking the solids coming from the fish tanks. The culture
water is purified and reused continuously.
[0046]. The present apparatus is an almost completely closed
circuit. The produced waste products; solid waste, ammonium and
C02, are either removed or converted into non-toxic products by the
system components. The water and energy requirements are limited
to an absolute minimum.
[0047]. .There are following advantages of the present invention:
• Less use of water
" Better growth in controlled culture
" Enhances disease resistance
" Proper estimation and sampling
" Less time consuming
" Use of fecal materials of fish for microbiological analysis.
" Fully controlled environment for the fish
" Lowwateruse
" Efficient energy use
" Efficient land use
* Optimal feeding strategy
" Easy grading and harvesting of fish
" Full disease control
" In a recirculation system, a high utilization rate of the
feed is beneficial as this will minimize the amount of
excretion products thus lowering the impact on the water
treatment system.
[0048]. The figures and the foregoing description give examples of
embodiments. Those skilled in the art will appreciate that one or
more of the described elements may well be combined into a single
functional element. Alternatively, certain elements may be split into
multiple functional elements. Elements from one embodiment may

Moreover, the actions of any block diagram need not be
implemented in the order shown; nor do all of the acts need to be

be understood that the appended claims are not necessarily limited to
the specific features or methods described. Rather, the specific
