Manual para productores en crianza de peces

La piscicultura es la crianza de peces, término bajo el que se agrupan una gran diversidad de cultivos muy diferentes entre sí, en general denominados en función de la especie o la familia.

 

Las instalaciones de piscicultura industrial se conocen como piscifactorías, aunque este es un término en desuso, debido a la diversificación que ha sufrido el cultivo, en depósitos, estanques, jaulas flotantes, etc.

1.1 ¿Qué es la piscicultura?

• La piscicultura es  la crianza de peces  bajo condiciones parcial o total mente controladas por el piscicultor.
• Se practica en estanques, presas, lagunas, tanques, jaulas y corrales.
• La crianza de peces puede hacerse en agua fría, agua templada y agua cálida; también en agua dulce, agua salobre y agua salada.

Este taller trata de piscicultura tropical de agua dulce

.
2.2 ¿Por qué se crían los peces?
• El pescado es un alimento de alto valor nutritivo.
• La producción natural de pescado no alcanza la demanda, especialmente en un país como la República Dominicana. Además, la pesca suele ser
variable a lo largo del año. 
• Una crianza de peces, por el contrario, brinda las siguientes ventajas:
– Mayor productividad que la de las aguas naturales.
– Mejor aprovechamiento de los recursos (tierra, agua, mano de obra y dinero). La piscicultura puede ser más productiva y rentable que otras actividades agropecuarias.
– Abastecimiento confiable y predecible de pescado para el autoconsumo o la venta.
• La piscicultura se lleva a cabo en casi todas partes del mundo que reúnen las siguientes características:
– Hay escasez de proteína animal para el consumo humano.
– La producción natural de pescado es limitada.
– Se dan los recursos hídricos adecuados.
– Existe mercado para la venta de pescado.
– Hay otras actividades agropecuarias que pueden ser integradas con la piscicultura
2.0 Tipos de Piscicultura
1.1 Piscicultura de subsistencia y comercial
• La piscicultura de subsistencia se orienta a la producción de pescado para la alimentación familiar.
• La piscicultura comercial se orienta a la producción de pescado para la venta.
• Ambas se diferencian por las especies cultivadas y el tamaño y peso a la cosecha.
• La piscicultura comercial generalmente requiere mayor inversión de dinero; pero el rendimiento también suele ser mayor.
• La piscicultura artesanal puede ser considerada de doble propósito: la producción de pescado para la alimentación familiar y para la venta, aprovechando la tecnología apropiada.

  16. I’m amazed, I must say. Rarely do I come across a blog that’s equally educative and engaging,
    and let me tell you, you’ve hit the nail on the head.
    The issue is something that too few people are speaking intelligently about.
    I’m very happy I came across this during my search for something relating to this.

  17. Aw, this was a very good post. Spending some time and actual
    effort to produce a top notch article… but what can I say… I hesitate a whole lot and never manage to get anything done.

  18. Today, I went to the beach front with my kids.
    I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the
    shell to her ear and screamed. There was a hermit crab inside and
    it pinched her ear. She never wants to go back! LoL I know this is entirely off topic but I had
    to tell someone!

  19. Outstanding post however I was wondering if you could write a litte more on this topic?
    I’d be very grateful if you could elaborate a little bit more.

    Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could connect

    I was curious to know how you center yourself and clear
    your head prior to writing. I have had a difficult time clearing
    my thoughts in getting my ideas out there. I do take pleasure in writing but it just seems like the first 10 to 15 minutes are
    usually lost simply just trying to figure out how to begin. Any ideas
    or tips? Cheers!

    as yours and I feel we could greatly benefit from each other.
    If you might be interested feel free to shoot me an email.
