Abstract
This study investigates the diversity and
abundance of aquatic insects in shrimp ponds in Jogendranagar, South 24
Parganas, West Bengal, India, with a focus on understanding the ecological
dynamics in shrimp aquaculture systems. Shrimp farming, particularly the
cultivation of Penaeus monodon, is a prominent economic activity in the
region, with approximately 60,000 hectares of brackish water aquaculture. Two
ponds, pond-A and pond-B, were selected to represent different aquaculture
practices and environmental conditions. Aquatic insects were sampled using
standard collection methods such as D-frame nets, sweeping nets, and
hand-picking. The specimens were identified to the lowest possible taxonomic
level, focusing on four primary orders: Hemiptera, Coleoptera, Odonata, and
Diptera. The study found that Hemiptera, particularly Corixidae (Water
Boatman), The most abundant, accounting for 35.48% of the relative abundance
(RA), followed by Coleoptera and Odonata. The results highlight the
significance of aquatic insects in maintaining the ecological balance of shrimp
ponds and emphasize the role of environmental factors such as vegetation and
hydrological stability in shaping insect communities. This research contributes
to the understanding of pond ecosystems and offers insights for improving
shrimp pond management practices.
