Pandalid shrimps
Systematic position: Pandalidae are members of the order Decapoda. While primarily marine organisms, certain species can inhabit coastal environments or aquaculture systems. In specific agricultural setups, such as integrated hydroponic-aquaculture facilities, they can pose challenges as pests that affect plant health.

Pandalid shrimps
Target crops: These crustaceans are a particular concern in closed-loop hydroponic systems where water-based crops like watercress or flooded rice cultivation are practiced. Their presence within the root zone can disrupt plant development in high-tech agricultural production environments.
Biology and life cycle: Pandalidae undergo a complex life cycle, featuring planktonic larval stages before settling. They are known for their distinct rostrums and sensitive behavioral responses to water temperature and oxygen levels. Their population dynamics are heavily influenced by the stability of the aquatic environment they inhabit.
Nature of damage: The primary harm is caused by mechanical damage to the delicate root structures of plants. By grazing on root hairs, these crustaceans interfere with nutrient uptake, stunt growth, and cause visible wilting. This damage often serves as an entry point for secondary infections caused by waterborne pathogens, leading to crop loss.
Protection measures: Managing Pandalidae in agricultural settings requires a multi-faceted approach. Key methods include:
- Installing fine mesh filters to exclude larvae from nutrient solutions.
- Maintaining rigorous water sanitation and equipment disinfection schedules.
- Monitoring water quality parameters to ensure unfavorable conditions for pest reproduction.
- Implementing biological control measures where applicable to reduce population density.
