This document discusses a study on the application of Integrated Multi-Trophic Aquaculture (IMTA) using a Stratified Double Floating Net Cage (SDFNC) integrated with biomonitoring to promote sustainable aquaculture. IMTA involves culturing different trophic levels together, like fish, shellfish, and seaweed, to reduce environmental impacts. The study looked at using an SDFNC, which allows for culturing multiple species without increasing farm area. Results showed rabbitfish and shrimp grown together in polyculture cages had good growth rates. Fish in IMTA cages in another area also exhibited positive growth in weight and length. The integrated system aims to balance productivity with environmental protection.

The increase of fishery production nationally and internationally may impact on the
potential emergence of a variety of environmental problems. The application of
sustainable aquaculture is urgently needed by breeding fish for commercial purposes
in a manner such that it has a minimum impact on the environment, contributing to the
development of local communities and generating economic benefits. The design of
the cage and farming practice in aquaculture activities are the important steps to
ensure that farming activity is still observed in order to anticipate the risk of organic
enrichment caused by the activities. The application of Integrated Multi-Trophic
Aquaculture (IMTA) on the Stratified Double Floating Net Cage (SDFNC) integrated
with biomonitoring are an appropriate solution to the ongoing productive farming
practices. IMTA is an aquaculture practice using more than one species of biotas
which have ecologically mutual relationship as a part of the food chain in the area at
the same time. The application of IMTA allows farmers to get several aquaculture
products in the same area without increasing the horizontal area of the farms.
