Salmonoids are especially demanding about water quality and high oxygen content. The oxygen concentration should be kept at least 5 mg/l throughout the year. This ensures good condition of fish and facilitates quick maturity without disturbances.
Sufficient oxygen content near the basin bottom (2 mg/l) prevents leaching of nutrients and in particular phosphor into the water. Dissolved nutrients have a detrimental impact on water quality and – at worst – can cause growth of cyanobacterium...

In either decorative fish ponds or fish farming ponds, HDPE geomembranes and Fish-Grade PVC are used to avoid soil contact and minimize water contamination. Geomembranes prevent both waste accumulation in the soil and leaching of harmful chemicals into the ponds such as ammonia, hydrogen sulphide, acidic constituents, iron and other potentially stressful compounds. This protection improves fish growth while reducing the risk of disease. HDPE geomembranes also reduce erosion, allow for easy removal of wastes...

Intensive use of extractive fishing is threatening important species and forces governments to impose temporary stoppages whilst the profitability of fishing fleets is decreasing and ship-owners are seeing their livelihoods threatened.
As a result of this and in order to satisfy the continually growing demand for fish to feed the world’s population, it has been necessary to breed different types of fish, crustaceans and molluscs in fish farms.
Fish larvae feed on multicellular microorganisms...

Economical fish and shrimp production requires maximum nutritional efficiency from feed. Enzymes, including phytase, xylanase, cellulase, protease, lipase, and amylase increase the availability of nutrients, increase absorption of nutrients during digestion, increase fish growth rates, and assist in the survival and thriving of fish in the larval stage. Also, the use of lower cost feedstuffs is made possible for aquaculture with the use of added enzymes. Nutrients that are not digestible using the...

Aquaculture is an increasing growth market. As worldwide fishing methods have disturbed the balance in Nature, today around 25 per Cent of fish caught comes from aquaculture - with tendencies rising. Today, a whole range of aquaculture techniques use fills. For this purpose Hewitech has fills for nitrification and lamella for effectively retaining sludge.

Ultraviolet disinfection systems in hatcheries, fish farms and aquariums have enabled operators to farm or keep greater yields of healthier stock.Water quality is key to commercial aquaculture operators. Poor water quality will have an impact on the ability to successfully hatch eggs, raise juvenile fish and grow strong, healthy stock, so naturally a large investment is made in water cleansing systems. Chemical methods, while effective at killing some water-borne microbes, can...

Maintain healthier ponds, increase stocking densities, and generate higher yield with optimum oxygen transfer. Maintaining the proper level of oxygen dispersion in your systems is critical to the success of your operation – and the life of your fish. Poor dissolved oxygen levels, fluctuating water temperatures, and stratification all can negatively affect fish health and pond production.
