Prawns
The family Penaeidae belongs to the order Decapoda. These are strictly aquatic organisms inhabiting marine and brackish environments. In biological and agricultural systems, they are recognized as significant commercial aquaculture species rather than pests of agricultural crops.

Prawns
This biological group cannot damage terrestrial agricultural crops as they lack the physiological adaptations necessary for feeding on plant tissues in a soil-based environment. Prawns are primarily filter feeders and detritivores, functioning as a vital component of aquatic food chains with no impact on field or greenhouse production.
The life history of these crustaceans is entirely dependent on water. Their developmental cycle encompasses stages such as nauplius, zoea, mysis, and post-larva. Since their physiological requirements include specific salinity levels and water temperatures, they are incapable of survival or activity on land where crops are cultivated.
Within agronomy, the relevance of these organisms is linked to the utilization of shrimp processing waste. Shrimp shell meal is rich in chitin, which, when applied to soil, acts as a stimulant for beneficial microbial communities, effectively suppressing soil-borne pathogens and certain nematodes.
- Improved soil structure through chitin supplementation.
- Enhanced plant immunity to various fungal pathogens.
- Promotion of beneficial soil bacteria and mycorrhizal fungi.
Control measures against these organisms are unnecessary as they pose no threat to plant cultivation. Instead, the sustainable recycling of crustacean-derived materials provides an efficient strategy for soil amendment and sustainable plant nutrition in various agricultural settings.
