Aquaculture often requires transporting live animals from one place to another. A large shipment of the same type of fish can be delivered via a hauling tank and truck if the distance is not too great.
But for long distances, or when the shipment is not large enough to justify a truck with . . . → Read More: Shipping Fish In Boxes
Temperature is the single most important physical factor controlling the life of a cold-blooded animal. Temperature is critical in growth, reproduction and sometimes survival. Each species of fish has an optimum temperature range for growth, as well as upper and lower lethal temperatures.
Below the optimum temperature feed consumption and feed conversion decline until . . . → Read More: Water Temperature And pH Required For Cage Aquaculture
In any aquaculture operation, whether it is a pond or recirculating system, water quality is your major concern — successful rearing of fish begins with a healthy aquatic environment.
Intensive culture, however, often taxes that environment: fish produce waste products, primarily ammonia that unless converted to non-toxic nitrate can set into motion . . . → Read More: Testing For Ammonia In Aquaculture Ponds

To incorporate adequate safety precautions when working with or transporting NH3.
Personal protection is the responsibility of both the employer and the employee. Anhydrous ammonia is a strong alkali that can cause death or severe injury to body tissue due to its caustic, corrosive, freezing and dehydrating . . . → Read More: Safe Handling of Anhydrous Ammonia (NH3)
Good water quality is essential to maintain optimum marron growth. To manage water quality, regular testing needs to be conducted. Relatively inexpensive testing kits are available through analytical supply stores. The following parameters should be monitored on a regular basis.
The optimum growth rates for marron is achieved between 170 C and . . . → Read More: Water Quality For Growing Marron In Aquaculture
Alkalinity refers to amount of carbonates and bicarbonates in the water and water hardness refers to the concentration of calcium and magnesium.
As calcium and magnesium bond with carbonates and bicarbonates, alkalinity and water hardness are closely interrelated and produce similar measured levels.
Waters are often categorised according to degrees of hardness as . . . → Read More: Water quality in freshwater aquaculture ponds-Water alkalinity and hardness
