Aquaculture is the farming of
aquatic organisms: fish, molluscs, crustaceans, aquatic plants,
crocodiles, alligators, turtles, and amphibians. Farming implies
some form of intervention in the rearing process to enhance
production, such as regular stocking, feeding, protection from
predators, etc. Farming also implies individual or corporate
ownership of the stock being cultivated.

 

 

 

 

For statistical purposes, aquatic
organisms which are harvested by an individual or corporate body
which has owned them throughout their rearing period contribute to
aquaculture, while aquatic organisms which are exploitable by the
public as a common property resource, with or without appropriate
licences, are the harvest of capture fisheries.
 

Grow Fish Anywhere

G.F.A Advanced System Ltd.
has developed and implemented a unique patented fully closed, zero
discharge intensive aquaculture system that is suitable both for
fresh and sea water fish. The system is based on an extensive
research done by Prof. Jaap Van Rijn
of the Hebrew
University of Jerusalem
. The system prevents environmental
pollution, and can operate in any climate regardless of the
availability of water resource or proximity to the sea. The system
has been tested and proven on a scientific basis and is now
operated commercially.
Our Unique Aquaculture Technology

Unique Aquaculture Technology


GFA unique
system overcomes several limiting factors that restrain the output
and effectiveness of fish farmers.

The accumulation
of inorganic nitrogen and organic waste products in intensive fish
culture systems is one of the major limiting factors preventing
further intensification. Inorganic nitrogen (especially ammonia and
nitrite) is toxic to fish and accumulates in the pond water through
excretion of ammonia by the fish and by breakdown of organic
solids. Most of the treatment systems used in today’s aquaculture
facilities are designed to facilitate the growth of nitrifying
bacteria which convert ammonia to nitrate. A drawback of the
ammonia removal by means of nitrification is the subsequent
increase in nitrate in the culture system. High nitrate
concentrations ought to be prevented since, at high concentrations,
nitrate has a toxic effect of fish and might be converted to
nitrite with an even higher toxicity. Daily flushing the ponds at
rates of up to 25% of the total system volume is generally
practiced to avoid nitrate build up.

However, such a
practice often causes considerable environmental impact and is
prohibited in many countries due to environmental and public health
considerations. With respect to organic waste products, most
aquaculture facilities are designed to mechanically remove the
organic waste from the culture tank. Often, the concentrated
organic waste is discharged from these facilities without
post-treatment and this practice together with the discharge of
nitrate-rich effluents is considered a major limitation in the
development of intensive fish culture systems.

Due to the need
for daily water exchange, existing intensive fish culture systems
are situated in areas with an ample clean water supply. Thus, for
economical reasons concerned with water supply and discharge,
culture systems for marine fish (including recirculating systems)
are exclusively situated in the vicinity of the sea. Marine fish
farming, whether practiced in seacages or in land-based farms, is
often subject to intensive public debate as the farms discharge
nutrient-rich effluents in coastal waters of often heavily
populated areas. Sustainable farming of marine fish is therefore a
major challenge in today’s aquaculture development.


Our
system developed by Prof. van Rijn and G.F.A Advanced Systems is a
zero-discharge system suitable for the culture of freshwater as
well as marine edible and ornamental fish. No water exchange takes
place and water addition is limited to compensate for evaporation
losses only. The system reduces inorganic nitrogen and
organic wastes from pond water by means of the induction of several
microbial processes among which: (1) fermentation: the conversion
of complex organic waste compound to low molecular weight organic
compounds, (2) nitrification: the conversion of ammonia to nitrate
and (3) denitrification: the conversion of nitrate to nitrogen gas
and the conversion of low molecular weight organic compounds to
carbon dioxide.

Denitrification


Key
Advantages:

• High output-
Avg. density of 70 – 100 kg of fish per m³ of water

• Maximum
freshness- Within a day from farm to plate

• Zero
discharge- No environmental pollution and Bio-Secure

• Produces
premium fish- No antibiotics, mercury and lead free fish

• Both saltwater
and fresh water

• Grow Fish
Anywhere (G.F.A) – Can operate in any climate regardless of the
availability of a water resource or proximity to the sea

• Non native –
enable the growth of non native fish in any region

Sustainability


At GFA, our sustainability vision is focused
on water conservation and energy savings technologies for the local
market. We believe that the future of our food consumption will
belong to environmentally friendly and sustainable production
driven by economic sense for high quality healthy
product.

The main aspect of the GFA systems is its Water Conservation and
Pollution preventing.

Our production system allows the production of marine fish species
in 100% recycled water systems. 1 kg of grain needs 1,000 liters of
water to grow to maturity. Our unique system enables us to produce
1 Kg protain (within the fish) in less than 10 liters loss due to
evaporation and do not discharge any waste water or pollution in
the process.

Another key aspect is Feed
Practices

. GFA systems that grow the fish in
land based tanks, enable the improvement of feed usage. Our system
allows, in comparison to sea cages (nets) and open pools, to better
managment of the Food
Conversion Ratio
(FCR). Less food for each Kg of production
means lower production costs and a real help for protecting our
environment.

    שלום
    אני מנסה להתקשר אליכם למספרים המופיעים באתר שלכם ולא מצליח.
    יש חקלאי הודי מעוניין במוצרים שלכם וגם לא מצליח לתקשר אתכם. וביקש ממני לעזור לו.
    אני מישראל ורצה לעזור לו.
    נא לשלוח לי כתובת מלאה ומספרי טלפון על מנת לשלוח לו
