Aquaculture

  1. Low head recirculating aquaculture system for Koi. The tank (diameter=4,56 m, volume= 18000 liters) is built with coarrugated, galvanized steel sheets. The base (concrete mixed with Sika polypropylene fibers) was waterproofed with SIKA 107 Top Seal and acrylic paint for swimmingpools. The water circulation and filtration run exclusively through two airlifts of 110 mm. They aim to create a circular current whose direction of rotation can be easily changed just moving the airlift's elbows. A Secoh air pump (41 watts) provides air to the airlifts via 20 mm flex PVC pipe. A third, external airlift will purge the dirt from the central drain. It will be powered by a second and smaller air pump coupled to a timer.

    Sistema de acuicultura de recirculación a baja presión para Koi. El tanque (diámetro = 4,56 m, volumen = 18000 litros) está construido con chapas coarrugadas de acero galvanizado. La base (hormigón mezclado con fibras de polipropileno de Sika) fue impermeabilizada con SIKA 107 Top Seal y pintura acrílica para piscinas. La circulación del agua y filtración funciona exclusivamente mediante dos airlifts de 110 mm. Al funcionar crean una corriente circular cuyo sentido se puede cambiar con sólo girar los codos de los airlifts. Una bomba de aire Secoh (41 watios) proporciona aire a los airlifts a través de tubo de PVC flexible de 20 mm . Un tercer airlift externo purgará la suciedad del desagüe central. Estará impulsado por otra bomba de aire de menor potencia acoplada a un temporizador.

    El nuevo estanque de Kois de Jesús de Frutos cuenta con 85.000 litros, 2,2 m de profundidad, y está impermeabilizado con una capa de poliuretano proyectado. Cuenta con 4 bottom drains y 3 skimmers 3. El filtro con Kaldnes estático funciona gracias a 4 bombas de aire Hailea V60 de 35 w cada una, conectados a 7 airlifts de 110 mm de diámetro que bombean agua de los 4 BD y de los 3 skimmers.
    Con tan sólo 4x35 W (140 W), se obtiene un caudal de 72.000 l/h.
    El proceso diario de limpieza del K1 estático se ha automatizado con temporizadores que de forma secuencial: 1) desconectan las bombas de aire que hacen funcionar los 7 airlifts, 2) activan una 5ª bomba de aire conectada a difusores que agitan el K1 para que se limpie durante 1 h, 3) activan dos bombas sumergibles para evacuar el agua sucia a un depósito subterráneo, desde donde se recicla para el riego, y 4)
    conectan de nuevo las 4 bombas de aire que alimentan los airlifts para reiniciar la filtración.
    El filtro tiene un fondo con pendientes hacia dos sumideros, que permiten un rápido drenaje manual.
    Una bomba de aire adicional se activa automáticamente mediante un temporizador durante 1 hora por día para airear los 4 BD y facilitar la absorción de suciedad del fondo.

    Images recorded on 23th/oct/2011. The new Koi pond of Jesus de Frutos has 85,000 liters, 2.2 m deep, and is waterproofed with a layer of projected polyurethane. It has 4 bottom drains and 3 skimmers. The filter works by 4 Hailea V60 air pumps of 35 w each, connected to 7
    airlifts of 110 mm in diameter. They pump water from the 4 BD and the 3 SK.
    With just 4x35 w (140 w), a flow rate of 72000 l / h is achieved.
    The homemade filter is filled with staticKaldnes K1. The daily cleaning process has been automated with timers that sequentially: 1) turn off the air pumps for the airlifts, 2) turn on a 5th air pump to agitate the K1 for 1 h, 3) turn on two submersible pumps to evacuate
    the dirt to an underground tank, where it is recycled for irrigation, and 4) turn on again the 4 air pumps driving the airlifts to restart filtration.
    The filter has a sloping bottom to 2 sewage drains that allow quick manual drainage. An additional air pump is automatically turned on by timer 1 h per day to aerate the 4 BD.

Aquaculture is defined as the production of aquatic animals and plants under controlled conditions for all or part of their lifecycle.

Aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish. The need to exchange reliable information on all related subjects is becoming a key issue for the responsible management of aquaculture.
