yeah they lay eggs
the big fish ate the smaller fish lol
even so the fish would have to be partially digested not still whole
To be fair in the novel they judged by the weight of the fishes they caught and zhenya caught a very big fish so he won. Idk why the manhwa choose to draw many small fishes when they could have just made the winning criteria the weight of the fishes caught, like in the novel
i dont think thats how fish work bruh
