Su Sıcaklığının Balık Yetiştiriciliğine Etkisi

Öz

Sıcaklık tüm canlı organizmaların üzerine olduğu gibi balıkların da tüm yaşamsal faaliyetlerini etkilemektedir. Ovaryum gelişiminden yumurta gelişimine, bağışıklık sisteminin çalışmasından, canlı ağırlık kazanımına kadar birçok önemli faaliyet su sıcaklığının etkisi altında gerçekleşmektedir. Yetiştiricilik açısından sıcaklığın önemi ancak biyolojik öneminin kavranmasından sonra daha iyi anlaşılır. Yumurta gelişimi için belirlenen en uygun sıcaklık dizini yavru yetiştiriciliğinde başarıya ulaşmanın neredeyse ilk basamakları- nı oluşturur. Optimal su sıcaklığının belirlenmesi ile balığın canlı ağırlık kazancının izlenmesi yemleme protokollerinin hazırlanmasında göz önünde bulundurulan en önemli kavramlar arasındadır. Termal etkinin altında besin alımı ve sindirim fizyolojisi yetiştiriciliğin çalışma alanına giren en ilgi çekici konulardandır. Zira yetiştirilen türden türsel özelliklerinin yanı sıra hangi şartlarda ve protokollerle zorlanarak en üst düzeyde performans elde edilebileceği yetiştiricilik yarışındaki en önemli argümanlardır.
