Tüm omurgalılarda olduğu gibi balıklarda da besinlerin sindiriminin gerçekleştiği organ sindirim kanalıdır. Bu kanal balıkların beslenme farklılıklarına göre morfolojik, histolojik ve hormonal olarak değişim göstirir. Bu değişim aynı beslenme tipi ve farklı türler arasında da görülmektedir.
Balıklarda sindirim kanalı türden türe farklılık göstermektedir. Beslenme çeşitlerine göre bağırsak uzunlukları ve kıvrımları farklıdır. Bazı balık türlerinde ise gerçek mide yapısı bulunmazken hormonal ve enzimsel olarak farklılaşmış mide benzeri yapıya sahiptir.
Sindirim kanalında besin alımı, açlık ve tokluk durumlarda, enzim salınımı gibi fonksiyonları yerine getirmekten sorumlu hormonlar mevcuttur. Bu hormonlar hipotalamustan salgılanarak sinir iletimi ile sindirim kanalına etki edebilirken, sindirim kanalı üzerinden salgılananlarda mevcuttur.
Bu derlemenin amacı balıklarda sindirim kanalının beslenme farklılıklarına göre türler arasındaki morfolojik, histolojik ve hormonal olarak etkileri belirtilmiştir.
