Aquaculture Frequently Asked Questions

The amount of total horse­power and size of Series II nec­es­sary for your appli­ca­tion depends on many fac­tors. These fac­tors include:
  • Type of species
  • Stock­ing den­sity of species (species /m2)
  • Tar­get har­vest and size of species
  • Pond geom­e­try and depth
  • Amount of water exchanged daily in pond
  • Ambi­ent and water temperature
  • Salin­ity of water
  • Alti­tude
  • Pond bot­tom con­struc­tion (earthen, con­crete, or lined)
  • Wind speed
  • Amount of sunlight
With­out knowing these key factors, it is dif­fi­cult to know for cer­tain how much aer­a­tion is required for your appli­ca­tion. We have pro­vided you with some sim­ple tools to assist in the bud­getary siz­ing of your project (Siz­ing Tools), how­ever the best way to truly quan­tify how much aer­a­tion and what size Series II to use for your appli­ca­tion is to con­tact our engi­neers for tech­ni­cal assis­tance.
Moor­ing the aer­a­tors to the pond is very sim­ple. There are three dif­fer­ent ways to secure the aer­a­tors for proper installation:
  • Stake Moor­ing via bam­boo or wooden posts
  •  Free Anchor / Drop Anchor Moor­ing
  • Span Cable Moor­ing
  1. Slide or hoist the AIRE-O2® Series II and flotation assembly into the water. To hoist the assembly, fasten a sling to the motor mount brackets. This is near the balance point for the entire assembly. Lift slowly and check the balance of the assembly before moving.
  2. Once the unit has been placed in the water, secure the aerator assembly with the four 3/8" x 3" capscrews on the motor mounting bracket at the desired angle. For shallow ponds, 30º is recommended for minimal bottom disturbance while deeper ponds may require a steeper angle for optimum mixing and bubble hang time at the deeper depth.
  3. Move the AIRE-O2® Series II to its location on the lagoon.
Moor­ing the aer­a­tors is very sim­ple and requires min­i­mal instal­la­tion time. Should you have any ques­tions, please do not hes­i­tate to ask the experts in aer­a­tion for assis­tance at
Aer­a­tion is nec­es­sary when dis­solved oxy­gen (DO) lev­els in the pond fall below crit­i­cal lev­els. This crit­i­cal level var­i­es from species to species. When DO falls below this crit­i­cal point, the species in the pond become stressed, stop grow­ing, and are sus­cep­ti­ble to dis­ease. Typ­i­cal low den­sity aqua­cul­ture appli­ca­tions do not require arti­fi­cial aer­a­tion since the bio­mass and oxy­gen demand in the pond is low. As stock­ing den­si­ties become higher, the bio­mass in your pond also increases, caus­ing an over­all higher oxy­gen demand. Aer­a­tion increases the level of DO in the pond so that the species in your pond have ade­quate oxy­gen lev­els to grow prop­erly in a stress free envi­ron­ment. The Series II aer­a­tor, in par­tic­u­lar, serves addi­tional crit­i­cal func­tions which can fur­ther assist your appli­ca­tion. These ben­e­fits include effi­cient sub­sur­face mix­ing, (which allows for max­i­mum oxy­gen dis­per­sion and mix­ing to increase DO lev­els through­out the pond) and the break­down of ani­mal and feed wastes; keep­ing pond bot­toms cleaner and decreas­ing risk of disease.
Cer­tain species (trout and cat­fish) and appli­ca­tions (race­ways, inten­sive farm­ing appli­ca­tions) require the usage of our pro­peller guard to pre­vent the dam­ag­ing of species. How­ever, for most appli­ca­tions and species, this pro­peller guard is not required. Please con­tact us should you have any ques­tions on whether your appli­ca­tion will require pro­peller guards.
There are many reasons our Series II aerators are more dependable than copycats:
  • Cost of Own­er­ship — Series II aer­a­tors are an invest­ment to the pond which require min­i­mal main­te­nance and have very long oper­at­ing life cycles. In fact, there are Series IIs that have been in the field for well over 10 years today. The sim­plic­ity of the Series II aer­a­tors’ design only requires minor parts replace­ment at a frac­tion of the cost of com­pet­i­tive aer­a­tor replace­ments. It is for this rea­son why Series II aer­a­tors are regarded as a pond invest­ment and not a pond consumable.
  • Supe­rior Per­for­mance – Please refer to (How It Works) and (Competition) to under­stand the ben­e­fits of its supe­rior per­for­mance and design. These sec­tions explain the numer­ous design fea­tures of the Series II which are crit­i­cal to a higher har­vest for your pond appli­ca­tion. Since the Series II aer­a­tors lead to a higher har­vest per pond than its com­peti­tors, each pond and har­vest will equate to a higher profit for your farm. Mul­ti­ply this by the lower cost of own­er­ship and there is no ques­tion the Series II aer­a­tors is the best value on the mar­ket­place today.
  • Cus­tomer Ser­vice – Aer­a­tion Indus­tries Inter­na­tional stands behind its prod­uct in both war­ranty and cus­tomer ser­vice. We fea­ture a multilingual cus­tomer ser­vice depart­ment and fac­tory autho­rized rep­re­sen­ta­tives world­wide, who can assist with any tech­ni­cal ques­tions or inquiries that you have about our Series II aer­a­tors. Please do not hesitate to ask!
  • More than 40 Years of Proven Suc­cess — The Aire-O2® aspi­ra­tor aer­a­tor has been proven to perform in this indus­try since 1974. Our equip­ment has been suc­cess­fully tested by world-renowned uni­ver­si­ties and insti­tu­tions, (Auburn Uni­ver­sity, Texas A&M Uni­ver­sity, Uni­ver­sity of Min­nesota, Louisiana State Uni­ver­sity, IFRIMAR, CIBNOR- Biohelis etc.) and diverse aqua­cul­tur­ists just like you!
  • Unequaled Test Pool and Research & Devel­op­ment (R&D) Facilities – Unlike any of our com­peti­tors in the indus­try, Aer­a­tion Indus­tries Inter­na­tional fea­tures a 100,000 gal­lon (378 m3) indoor test facil­ity with over 18 feet of under­wa­ter win­dows for view­ing. We are con­tin­u­ously test­ing aer­a­tion equip­ment in the con­stant quest for superior equipment. In addi­tion to our own prod­uct devel­op­ment and test­ing, we have tested our com­peti­tors aer­a­tors and, there­fore, can state that there is no equal to the Series II when it comes to com­plete oxy­gen trans­fer and cir­cu­la­tion (See our Com­pe­ti­tion page for details). If you are inter­ested in vis­it­ing our com­pany and see­ing our test facil­i­ties in per­son, please con­tact us to arrange for a visit to our head­quar­ters.
