摘要:腸道可以吸收營養(yǎng)物質(zhì)并抵御病原體、微生物和細菌毒素進入內(nèi)部環(huán)境,因此在魚類健康中起著重要作用。作為魚類與外部環(huán)境接觸面積最大的器官,腸道受到多種因素的侵害,嚴重制約了魚類的健康生長。文章從魚類腸道組織結(jié)構(gòu)、腸道的屏障功能、引起腸道損傷的因素以及有效緩解腸道損傷的物質(zhì)等四個方面進行綜述,可為進一步了解魚類腸道健康的分子機制及相關(guān)產(chǎn)品的研發(fā)提供參考。

Abstract:Intestine plays an important role in fish health as it can absorb nutrients and defend against pathogens,microbes and bacterial toxins entering the internal environment.As the organ with the largest contact area between fish and the external environment,the intestine is invaded by many factors,which seriously restricts the healthy growth of fish.This article reviewed the intestinal tissue structure, intestinal barrier function,factors that cause intestinal damage and substances that could effectively alleviate intestinal damage in fish,in order to provide certain theoretical basis for protecting fish intestinal health and promoting the healthy development of aquaculture industry.
