About This Presentation
Title:

Stress Factors in Aquaculture

Description:

We need to see the various stress factors which hamper the growth of fish and shrimp in controlled aquaculture environments. The objective is to recognise the stress causing factors and how they affect growth of the cultivated shrimp and fish. In the end we need to showcase how aeration can help reduce the stress on shrimp and fish being cultivated – PowerPoint PPT presentation

Stress Factors in Aquaculture
2
What is Stress ?
  • Stress is any condition that causes physical or
    mental discomfort that results in the release of
    stress-related hormones or results in specific
    physiological responses.
  • Stress can be physical, psychological, or
    environmental.
  • Stress can either be short and sudden, or long
    and chronic. 
  • Mild, short-term stress has few serious health
    effects, but long-term stress or severe,
    short-term stress contribute to many of the
    illnesses and deaths in aquarium fish.

Effect of Stress on Fishs and Shrimps Health
  • Short-term stress will cause an increase in heart
    rate, blood pressure, and respiration
  • The fish can only maintain these altered states
    for a short period of time and then they will
    adapt or the stress will become chronic.
  • In addition to having a negative effect on
    growth, reproduction, and digestion, chronic
    stress will also lower the ability of the immune
    system to respond effectively and fully.
  • Powered immune response is what allows parasites,
    bacteria, and fungi to infect a stressed fish and
    cause disease and death.

Causes of Stress
  • Elevated Ammonia
  • Elevated Nitrate
  • Improper PH level
  • Fluctuation in Temperature
  • Improper Salinity
  • Low Oxygen level
  • Medication and Water treatments
  • Harassment from Other Fish

How To Eliminate Stress
  • One can limit or prevent many causes of stress.
  • Acute stress is more obvious and needs to be
    addressed very quickly. Chronic stress is often
    not visible. 
  • One should maintain the Ammonia and Nitrate level
    in the water.
  • Maintain proper PH Level of the water.
  • Maintain the DO in the water by using good
    aeration technique.

Why AirOxi Tube?
  • AirOxi Tubeis one of the latest technologies for
    aquaculture aeration.
  • It is designed specially for commercial
    aquaculture and has been successfully installed
    in hundreds of acres of aquaculture ponds.
  • It has high efficiency in both salt water and
    fresh water.
  • AirOxi Tubes are made with a blend of materials
    that provide durability and smooth air flow.
