Aquaculture

Balancing water quality is a key factor in aquaculture eco systems. Unhealthy water conditions negatively impact aquatic life by increasing mortality rates. EnviZyme’ microbial inoculants use beneficial bacteria that assist in maintaining healthy conditions naturally and effectively. EnviZyme’ range of microbial solutions support improved growth, survival and increase disease resistance. The end result is increased yields and profits for farmers.

Applications

Stock waste can dramatically increase nitrogen levels. Removal of ammonia, nitrites, and nitrates is an especially important and difficult process to maintain in aquaculture. Advantage of EnviZyme solutions:

  • Enhance conditions for better health and greater stocking density
  • Make the nitrification and denitrification processes more robust for more efficient ammonia removal
  • Shorten recovery time after spikes, improve effluent, and reduce permit violations
  • Increase the lifespan of critical pieces of equipment by preventing ammonia-related corrosion

Biological oxygen demand (BOD) and chemical oxygen demand (COD) are important indicators of organic pollution contributed by commercial feeds, accumulation of waste, and decomposition of dead fish. Oxygen demand also directly affects dissolved oxygen (DO). Advantages of EnviZyme solutions:

  • Maintain optimal BOD and COD levels to ensure adequate DO is available to cultured species
  • Compliance with tightening discharge limits and elimination of permit violations
  • Enhanced enclosure stability for less frequent and less severe upsets
  • Improved performance in cold waters or cold weather conditions

Depending on location, aquaculture facilities may have costly and limited options for sludge disposal, especially as stricter regulations necessitate higher standards of treatment. EnviZyme offers both enzymatic and biological solutions to:

  • Prevent overcrowding of tanks as sludge volume accumulates
  • Improve odor and aesthetics of the aquaculture facility
  • Enhance sludge treatment and improve dewatering performance
  • Reduce sludge volume for lower handling or disposal costs
  • Accelerate stock tank turnaround between batches by reducing solids level
  • Recover capacity of lagoons and defer costly dredging
  • Comply with regulations and eliminate fines or legal consequences
  • Lower operational costs for chemical additives, energy, and labor

Treatment of rearing water requires a delicate balance of nutrients in order to support a healthy biomass and achieve optimal efficiency. EnviZyme offers products that provide essential micronutrients to supplement the basic metabolic needs of wastewater biology and ensure an optimized nutrient (C:N:P) ratio.

  • Supports water quality and overall well-being of aquatic organisms
  • Stabilizes biological populations and nutrient-deficient conditions
  • Reduces sensitivity for fewer fluctuations and aids in smooth start-up
  • Supports COD/BOD removal

A well-developed microbial community can take weeks or months to become established with only native microorganisms, and to operate as efficiently as possible, it is important to have the right microorganisms. EnviZyme offers products to:

  • Allow the start-up or turnaround period to happen faster and with greater predictability
  • Avoid delays and health issues associated with poor water quality
  • Jumpstart or recover the ability to remove organics
  • Facilitate quicker colonization of filter media, biofilm, and other surfaces
  • Establish a diverse and stable microbial ecosystem to competitively exclude pathogens
  • Provide safer enclosure cleaning between batches

Water Quality

Regulation

Water quality must be monitored to maintain a healthy aquatic environment. Key parameters vary by species, but should fall within ideal ranges listed above.

Organism Health

Small deviations in water quality negatively impact aquatic life and can result in emaciation, gill opercula malformation, and gill filament ulceration.

Specialized Solutions

With a large microbial portfolio, our blends are much more effective than naturally occurring microorganisms at enhancing rearing water quality, especially in high stocking densities.

Ammonia Conversion

Nitrification

Fish waste is in the form of ammonia and ammonium. Nitrification prevents these from rising to toxic levels via conversion into less toxic compounds, nitrite and nitrate, through nitrifying bacteria.

Denitrification

Following nitrification, denitrification converts remaining unwanted nitrites into nitrogen gas, removing bioavailable nitrogen and returning it to the atmosphere.

Two-Pronged Approach

EnviZyme's nitrification solutions are formulated with a blend of nitrifying microorganisms to provide a consistent seed of both nitrifiers and denitrifiers for ammonia and nitrate conversions.
