What kind of hazards can invertebrate pests create in aquatic systems?

Invertebrate pests can pose health and safety hazards in aquatic systems. These organisms may include species such as certain types of mosquitoes or freshwater snails that can carry diseases harmful to humans and animals. For example, mosquitoes are known vectors for viruses like West Nile virus and Zika virus, while certain snails can host parasites causing schistosomiasis. The presence of these pests not only threatens public health but can also complicate water management strategies and necessitate costly control measures.

While some invertebrate species may enhance the visual appeal of an aquatic ecosystem or provide habitat for wildlife, these benefits are overshadowed by the risks posed by harmful invertebrate pests. Increased recreational fishing or other positive aspects related to invertebrates typically pertain to non-pest species that support ecological balance rather than pose direct threats. Thus, understanding the potential health risks associated with pest species is crucial for maintaining safe aquatic environments.
