Marine Low Carbon Day 8

Participants: Interns

Guides: Farm Manager & Aquaculture Technicians

Date: 21 May 2026

Venue: Shrimp Aquaculture Farm, Kattur (Near Ponneri)

Theme: Commercial Shrimp Aquaculture

Focus: Sustainable Farm Management

Scope

To provide participants with practical exposure to commercial shrimp aquaculture operations and sustainable farm management practices. The visit aimed to enhance understanding of shrimp production systems, resource-efficient farming techniques, and the environmental considerations associated with aquaculture.

Content

Participants visited a commercial shrimp farm in Kattur and observed various stages of shrimp production. The farm manager explained pond management practices, stocking densities, growth cycles, and feeding strategies used in shrimp culture. Interns observed the operation of submerged aerators, which maintain adequate dissolved oxygen levels essential for shrimp health and growth. The session highlighted sustainable interventions, particularly the farm's innovative water recycling system, where water from one pond is reused in another to reduce water consumption and minimize effluent discharge. Participants also witnessed shrimp harvesting operations and observed the sorting and handling of harvested shrimp. Hands-on interaction with live black tiger shrimp allowed interns to examine anatomical features such as the exoskeleton, appendages, and body segmentation.

Sustainable Innovation Highlight

Water Recycling System

The farm utilizes an innovative water recycling system where water from one pond is reused in another, significantly reducing water consumption and minimizing effluent discharge into the environment.

Submerged Aeration

Advanced submerged aerators maintain optimal dissolved oxygen levels, ensuring shrimp health and growth while optimizing energy usage and operational efficiency.

Hands-On Learning: Shrimp Anatomy

Exoskeleton

Observed the protective outer shell structure of black tiger shrimp

Appendages

Examined the various appendages used for movement and feeding

Body Segmentation

Studied the segmented body structure of live specimens

Live Observation

Hands-on interaction with live black tiger shrimp specimens

Harvesting Operations

Harvesting Process: Participants witnessed the complete shrimp harvesting operation
Sorting & Handling: Observed the sorting and handling of harvested shrimp

Outcome

Participants gained a practical understanding of commercial shrimp farming practices, including pond management, aeration systems, feed management, and harvesting techniques. The visit demonstrated how resource-efficient technologies, such as water recycling, can improve sustainability in aquaculture. Interns developed awareness of the environmental challenges and responsibilities associated with shrimp farming, including water quality management and ecological impacts. The hands-on experience strengthened their understanding of shrimp biology and reinforced concepts related to responsible aquaculture, sustainable seafood production, and environmental stewardship.
