Ecologically sustainable aquaculture based on symbiotic technology is set to revolutionise the coastal aquaculture industry in the country. The aquaculture based on symbiotic technology is a guaranteed way for achieving Prime Minister Narendra Modi’s vision for doubling the aqua farmers’ income, said Tamil Nadu J Jayalalithaa Fisheries University (TNJFU) vice-chancellor G Sugumar. He was speaking after inaugurating the project on standardised pond-based culture technique for commercially important marine finfishes and pond-based recirculated aquaculture system (RAS) for vannamei shrimp at Chippikulam near Thoothukudi. Sugumar said the initiative launched by Kings Infra in association with the university to promote the project would help the aquaculture farming practice to be truly sustainable in the country. The recirculated aquaculture system (RAS) empowers farmers to utilise water to the maximum sustainable levels by eliminating possible wastage by converting the same to another resource.
