The researchers studied how using probiotics can help giant freshwater prawns grow better. They tested different types of probiotics on the prawns in twelve ponds. The prawns treated with both Zymetin and Super PS grew the most and had the highest production. These prawns were bigger, had a better growth rate, and produced more compared to those without probiotics or with only one type of probiotics. The ponds with probiotics also had good water and soil quality. Using a combination of Zymetin and Super PS can help farmers increase their prawn production.
