Tridge summary

India's Central Marine Fisheries Research Institute (CMFRI) has successfully implemented Integrated Multi-trophic Aquaculture (IMTA) in collaboration with local fish farmers in Moothakunnam, Ernakulam, resulting in the production of approximately one tonne of green mussel from 150 strings around four fish cages. Despite the harvest happening during the Covid lockdown, the produce was quickly sold out. The institute believes that IMTA is economically viable and well suited to Kerala’s conditions, as it leads to better growth in fish and seaweed, and helps maintain environmental sustainability by using excess nutrients and carbon dioxide from the cage farm. CMFRI plans to promote this innovative technology among coastal communities to enhance income.

The project was undertaken by India’s Central Marine Fisheries Research Institute (CMFRI), working with fish farmers in Moothakunnam, Ernakulam. CMFRI started the venture in December last year as part of its research initiative for developing a sustainable cage fish farming model suitable to Kerala’s ecosystem. In the first harvest among the three crops of the integrated farming, around one tonne of green mussel was produced from 150 strings hung around four fish cages. The individual mussels grew to 72 g, which is a successful growth rate in mussel farming, according to CMFRI. Despite the harvest taking place during the Covid lockdown, the entire produce sold out quickly. According to experts from the CMFRI, a good harvest with better growth rate of green mussel showed that IMTA is economically feasible and well suited to Kerala’s conditions. A scientific team led by Dr Shoji Joseph, principal scientist of CMFRI, also observed that the fish inside the cage attained better growth ...
