Ferma acvacultura  in system recirculant

Recirculating Aquaculture System (- RAS)

Ovidius Aqua Line

  1. Scurta descriere a Fermei de sturioni in momentul actual:

Ferma Ovidius Aqua Line localizata pe Malul Dunarii in localitatea Borcea, jud Calarasi isi desfasoara activitatea intr-o incinta (curte) de 1500 mp. In aceasta incinta este amplasata o hala cu suprafata de 600 mp, izolata termic, impartita in spatiu crestere, spatiu depozitare, spatiu procesare icre si carne (autorizat DSV) si birouri.In cadrul acestei ferme sunt crescute in vederea comercializarii specii de sturioni (morun, nisetru si pastruga) si pastrav, atat adulti reproducatori cat si puiet.

    • Diesel Generator 15kw
    • Photovoltaic System 10kw
  • Species of Fish used (tested) in your laboratory :,
  • Rainbow Trout: 6000 pcs x 300 grams / piece
  • Sturgeon: , 150 adult sturgeon 5-10 kg / piece
  • Identifying the stress factors in precise context
  • variations of dissolved oxygen percentage:

due temperature variations  

– feeding process

– Low water flow in the recirculant system

  •  high nitrate levels,

                        – feeding process

                        – biofilter malfunction

                        –  low performance of biofilter

  • low water recirculation frequency/debit

                        – mechanical malfunction

                        – power outage

  • Low feed absobtion and high mortality risk

– due to high water temperature during summer months

  • Evaluation methodology /process :
  • manually testing water parameters
  • fish disection and observation,
  • fish meat taste
  • Water quality parameters monitoring : daily – oxygen (oxygen meters), temperature (thermometer) and water levels (visual observation)weekly  -nitrates and nitrites (paper tests) and pH level (pH-meter)monthly  – other parameters
  • Sensors requirement:
    • Dissolved oxygen
    • Ph
    • Temperature
    • Flowmeter
    • Water level sensor
    • Nitrates
    • Nitrites

H.     Tests Validation:

  • Collaboration with your public agencies :

                                                – ANPA – regularly checking of fish number

                        – DSV – regularly Water quality parameters monitoring

  • Other tests validation

   – Water quality parameters monitoring in private companies
