Land Based Hatchery
Aquaculture operations especially within the confines of hatchery, can pose significant problems for fish farm owners and the environment. Some of these problems include oxygen depletion, damage to benthic ecosystems and bacteria pollution. In order to increase spawning & larvae survival rates, aquaculturists make use of a wide range of chemicals in their operations.
However, this leads to other problems too. For instance, it is estimated that most of the antibiotics used on fishes are lost to the environment due to leeching from fecaes and uneaten fish feed and they end up being bounded to particles in the sediment, leading to chemical pollution in aquatic systems. Pesticides are used as antifouling agents to deter the growth of fouling organisms but they are now known to reside in the organisms and the aquatic systems. This pollutes the environment and harms the farmed organisms.
SIF Technologies is the leading supplier of chemical free water treatment systems to more than 50% of Singapore’s active breeders and exporters of ornamental fish and food fish farms. Major ornamental fish exporters, food fish farms, hatcheries, and one of the largest oceanariums in Asia have benefited from the deployment of the DPA system and customized solutions that SIF Technologies has provided. We have been involved in projects that include species such as Ornamental fish, Sea Bass, Tiger Grouper, Red Snapper, Sea dragons, Crabs, Prawns and Blue Lobsters.
Our clients have improved the quality of water in their aquatic systems, enhanced the quality of their livestock and cut down on their business costs, while keeping to environmentally friendly practices. Furthermore, SIF Technologies has also formulated Super Mineral in its arsenal. The Super Mineral is able to neutralize the effects of Ammonia, Nitrate, Nitrite and possibly all other harmful substances that may have ill effects on the live stock.
In 2009, SIF was awarded a MND S$1.4m grant to develop a Recirculating Aquaculture System (RAS) for Land based farming of food fish. SIF was selected for this project based on its current track record with the aquaculture industry. The Land based Recirculating Aquaculture system was successfully developed in end 2009 with a successful harvest of sea bass in 2010.
SIF currently operates one land based hatchery in Singapore and has plan for a second one. We have developed a proprietary water treatment process for use in hatchery which saw our sea bass larvae survival rate maintained consistently at 40 to 51%. We have put together a comprehensive operations protocol and procedures manual as part of our technology transfer programme to our partners. SIF believes that a healthy fingerling is the key factor for sustainability in the food-fish industry.
SIF firmly believe that quality water management is one of the main key for successful food-fish farming but unfortunately, this is one area that is often ignored by the traditional aquaculture farmers.
Re-circulating Aquaculture System
Land based farming predominantly face issues over the quality of water. This variable is dependent on the uptake source and is subject to environmental changes which can drastically affect production. Fish are totally dependent upon water to breathe, feed and grow, and to reproduce. To a large extent, water quality determines the rate of mortality and survival in an aquaculture farm.
Our DPA technology complements existing recirculating technology to create a solution for sustainable land based aquaculture farming where water parameters are controlled and wastewater is effectively recycled. Our technology disinfects the water without the use of chemicals to accelerate the growth and survival rate of larvae in hatcheries. This is a major disinfection component for all hatcheries to ensure larvae survival rate for the first 40 days.
SIF has successfully aided many hatcheries in Singapore and in the region, increase larval survival rate by more than 400%.
Other than larval survival rate, this proprietary technology will also impact dissolved oxygen level & saturation whereby increasing spawning rate, lower mortality during weaning and nursery stage. Our DPA Technology has been applied across land based aquaculture farms in Singapore, Indonesia, Thailand, Sri Lanka, and Malaysia.
Flow Through Aquaculture
Flow through systems have the luxury of acquiring water from a convenient water source. This creates a dependence on the natural environment to produce quality water for livestock management. The risk involved in such over-dependence can impact production lines in the event of contamination or unfavorable water parameters such as, Red Tide, algal bloom, chemical & bacteria contamination etc.
Our DPA Technology complements this system by assuring a regulated increase in dissolved oxygen and a chemical-free disinfection component. Being modular, it can be implemented at various stages to mitigate the risk and control the parameters of water for sustained quality production.
We have implemented our DPA technology in flow-through land-based hatchery and aquaculture farms as a contingent isolated water treatment system during Red Tide and algal bloom conditions. This contingency has spared a number of flow-through land-based farms in Singapore the decimating effect of Red Tide when it struck the shores of Singapore recently and some time ago.
Aquaculture Site Technical Assessment
90% of land-based farms in Asia operates purely on traditional know-how and sheer experience. It is a non-predictable model that operates at the mercy of weather conditions, environmental factors, and management skill sets. For aquaculture farming to be successful, one will need not just traditional know-how & experience but a combination of evidence-based science and technology to give the farming model predictability.
One of SIF’s key expertise is our ability to tackle issues from a scientific angle and approach. We have been commissioned by global aquaculture players to do technical audit in their farms which resulted in major operational restructuring. We were able to highlight the potential areas where production yield could be impacted, detection of dead-zones in grow-out areas and a thorough analysis of their farm water quality; starting from the seawater pumping stations, to their hatcheries and finally to the grow-out floating cages. SIF has developed a comprehensive evaluation methodology and bio-secure protocol for evaluating a site’s existing setup. Our goal is to help traditional aquaculture farms embrace science and technology albeit building a responsible and sustainable farming model.
Ornamental & Recreational
Singapore is the top exporter of ornamental fish in the world, and is known not only as the “Ornamental Fish Capital of the World” but also as a “One-Stop Shop” for global ornamental fish business. Exporters deal with 500 species of ornamental fish, buying from the local farms, which accounts for about 40% of the sales, as well as from farms in the region and elsewhere for re-exporting.
In 2002, Singapore exported 230 million pieces ornamental fish to more than 70 countries. In terms of the numbers of species and varieties, Singapore transacts about 50% of the 1,000 species and varieties sold commercially worldwide. Singapore is not only the top exporting country; it is also one of the world’s largest producers of farm-bred ornamental fish. About 110 million pieces ornamental fish were produced in Singapore. This accounted for 44% of the fish exported from Singapore
The ornamental fish industry is highly labour intensive due to the need to care, conditioning, cleaning and packing for the fishes.
SIF has provided a variety of solutions and systems to more than 50% of the active ornamental fish exporters in Singapore. In particular, our technology has helped exporter doubled their stocking density by more than 200% whereby reducing their air freight cost, improve spawning rate, and reduction in vaccine usage.
A pre-dominant problem faced by live seafood producers globally is the availability of holding facilities with proven life support systems and technologies for holding live seafood in a premium condition.
In 2011, SIF teamed up with CWT Fresh (Part of CWT Group, a global logistic player) to set up a world first Aquahub in Jurong Cold Hub I. By offering a sea-to-air link, this AquaHub will act as launching pad for live, premium sea food product diffusion into the global market
When CWT Fresh first put together the blue print for the Aquahub, they knew that they need to find a partner who has the necessary track record in providing technological solutions for live support systems. SIF was the natural choice. Today, the dream of developing a cost effective live holding logistic hub is now a reality
