Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, it is necessary to remove the impurities in the digestive track of fish before consuming it. [1] However, in the case where it is difficult to remove the impurities of the fish due to it being small, there will be no need to remove it. [2]
Generally, when fish is cooked without cleaning the digestive tract, the intensity of the heat results in the permeation of the impurities in the digestive tract into the flesh. Therefore, it will not be permissible to consume the fish.
