Penaeus Japonicus

Paneaeus Japonicus

The giant tiger shrimp (Penaeus monodon) is a species of shrimp belonging to the penaeid family. Both sexes reach approximately 36cm of length when adult, and females can weigh more than 650g, making of this species the largest species of shrimp. As a result, the Penaeus monodon shrimp is the most widely farmed in the world, but sometimes decimated by viral or bacterial during farming, which is why it is gradually losing ground to the white shrimp (Litopenaeus vannamei ), which is less prone to livestock-related diseases. More than 900,000 tons are consumed annually, two-thirds of it come from aquaculture.

Holothuria Atra

Holothuria Atra

Method used to collect broodstock of Holothuria Atra, store it, induce spawning and raise the larvae.


I) Spawning

Spawning is induced in Holothuria Atra by heat shock and also by a powerful drying process followed by watering. Eggs fertilized by the method of thermal shock are obtained. All parents are introduced into seawater at 27°C. Ten minutes later, they are transferred to a tank containing seawater at 30°C. Within five minutes, the male sperm is ejected and drives one of the females to lay thirty minutes after. The female lays 800,000 eggs, which hatch after 48 hours to give 750 000 larvae in the form of early auricularia. The hatching rate is 93.8%.


II) Larvae Rearing

  • Auricularia larvae are placed in our tank "ATRA". The sea water in the tanks where the larvae placed is at 26-28°C and has a pH of 8.2-8.4, and a degree of salinity of 34-35 ppt.
  • After ten days in this tank, larvae take their auricularia terminal form.
  • At the beginning of this stage, they are on average 440 microns and at the end, 404 microns. The fifteenth day, auricularia is transformed into doliolaria. Barrel-shaped, doliolaria larvae are on average 360 microns. This stage is of short duration, and last from 4 to 5 days. The larvae are then transformed into pentactula, and take a tubular form, with five tentacles at their anterior end and a single tube foot at their posterior end. They measure an average of 550 microns and feed greedily benthic algae and detritus.
  • Mounting plates are placed in the vessel.

The method for spawning and larval rearing are summarized in the following "Breeding Table"
  • Name: Holothuria Atra
  • No. Parents: 12
  • No. of Eggs: 800,000
  • No. Auricularia: 750,000
  • No. Pentactulae Holothuria Atra: 48,000

Tilapia

Tilapia

CINCO, closed-circuit breeding station

This system, working with green sea water (color id due to phytoplankton), can be used in intensive or semi-intensive modes. Fish receive adequate nutrition in the form of pellets. Fish fertilize the environment and at the same time promote the growth of phytoplankton.

Even counting with a laboratory with sophisticated devices to perform spawning, it is clear that egg production is very expensive. A better solution is to buy the tilapia while they weigh 15 to 20 grams for 1 to 2 cents of euro.

SWAKI Ltd. Pte.

The genius is not to complicate the copy of nature, but to find simple solutions that copy nature.

New developed and applied technologies


With SWAKI’s activated coal system, water denitrification is no longer necessary

Before placing activated carbon into our system, we perform a special treatment to ensure the proper removal of phosphates, ammonium, nitrite and nitrate from the water via the use of activated carbon. After some time, coal becomes inactive and cannot hold the waste any longer as micro-bubbles become saturated with waste. Therefore, we remove the active carbon filter, and we treat it in such a way that it recovers its waste-filtering capabilities. SWAKI’s system has the additional advantage of operating within closed-circuit stations. While most fish farmers nowadays still remove waste using conventional systems, we work with sophisticated technologies.

Ozone water cycle

Ozone molecules enter into contact with different water substances and thereby begin oxidation (electrolysis). Oxidation usually lasts about twenty minutes before ozone’s third molecule is freed, and it becomes oxygen. However, the time for the development of new bacterial cultures is shorter than twenty minutes, and thus SWAKI has developed an anti-ozone tissue by which all ozone molecules are retained and transformed into oxygen again. With this technology we guarantee a water free of ozone and a good growth process of the new cultures before the water returns to the fish or shellfish’s habitat. In the compartment there are two walls, one for sludge retention (vires, burned bacteria), and the other one for holding the rest of the ozone.

Wave production to simulate tides

Be it the sea, or a river, or a pond, there are currents underwater always. These tides carry minerals, food, oxygen and odor in the water which are essential for the development of fish products in all sorts of water in the world. In aquaculture, water flow and pumps replace the work of nature. Yet, it is not exactly like in nature with its winds, thunderstorms, the Oersted1 of the moon and weather instability. This is why SWAKI imitates nature with nano devices capable of reproducing natural forces. The nano devices are adjustable to the flow and can be manipulated in any desired direction, just as in nature. To the best of our knowledge, this system is not yet available in fish farms.

Bio fluorescence

SWAKI has introduced this system into its new technology in order to better understand and control the production of fish products in aquaculture and develop fish species not yet available in commercial fish farms.

Feeding area for shellfish

SWAKI new technology is based on replicating the environment that shellfish find in nature. To avoid crustaceans’ volume shrinkage, they need to move around to obtain different nutrients in different parts of the water mass. Normally, in aquaculture all these products are in compartments or selling cages resulting in a shrinking of crustaceans’ volume. In addition, shrunk shellfish volume can produce allergies to these products. Mindful of these issues, SWAKY has put a feeding pool directly in the close-circuit pool to solve the loss of flesh volume by fish in captivity

Drum filter and skimmer

In the closed-circuit station system for some fish, we set up our drum filter instead of the activated carbon filter (patented more than three years ago), which construction is realized in HDPE and PP. See technical drawings with the skimmer at the left hand side and the filter at the right hand side of the text chart. We also place our skimmer, developed over three years ago. The advantage of these two products is that we can build them to secure the exact volume and flow of water that is necessary for the correspondent closed-circuit station.

SWAKI Ltd. Pte.

Conclusion

To be a good fish farmer, we study the ichthyology, the morphology and the exact environment of each fish and shellfish product that we want to develop in aquaculture. With this knowledge, we develop and build our closed-circuit stations, taking care of our aquaculture products.
