Faculty of Fisheries and Marine Sciences of Diponegoro University hosted the “Aquaculture Supporting Mangrove Webinar Series 3: Integrated Multi Trophic Aquaculture” on last Wednesday, June 16th 2021. This webinar presented Dr. Roel H. Bosma, Prof. Dr. Marc Verdegem (Wageningen University) collaborated with speakers from Department of Aquaculture, Faculty of Fisheries and Marine Sciences Undip, Prof. Dr. Ir. Sri Fortune, MSc; Restiana Wisnu, MSi and Lestari L Widowati, MSi.

In this webinar series #3, it is also informed that the consortium of Building with Nature Indonesia presented information about the Integrated Multi-Trophic Aquaculture system, starting from the background, concept, and its implementation. The IMTA system is one of the approaches used by Building with Nature Indonesia program which aims to improve pond management practices on the North Coast of Java, especially in Demak Regency with environmentally friendly and sustainable principles.

Participants who attended webinar are from various institutions, universities, practitioners both in Indonesia and several neighboring countries such as Malaysia and Philippines. Prof. Sri Rejeki conveyed the IMTA concept as an environmentally friendly cultivation technique with zero waste principles. The discussion with webinar participants is led by Dr. Roel H. Bosma regarding motivation, application as well as obstacles and challenges in implementing this system in a comprehensive manner.

The two speakers educated and shared knowledge about important aspects of IMTA based on the Project to design Aquaculture to Support Mangrove reforestation in Indonesia (PASMI) which was successfully implemented in 2016-2019.

Prof. Marc as the keynote speaker, explaining live from Wageningen, The Netherlands, gave material about Nutrious Pond, the principle of effective feed management in aquaculture. Since 2012, he has collaborated with WorldFish in developing the concept of ‘nutritional ponds’ and since 2020 has also been involved in an integrated research project with the theme ‘Climate smart farming’ in collaboration with IPB University Bogor.

This series of webinars is carried out with the support of Wetlands International and Ecoshape, in collaboration with Wetland Foundation, Faculty of Fisheries and Marine Sciences UNDIP and Blue Forest Foundation. This webinar aims to disseminate ideas and to discuss the development of sustainable and integrated coastal aquaculture with mangrove forests through a collaborative approach to nature.

Deputy Dean II, Prof. Dr. Aristi Dian Purnama Fitri, SPi, MSi. closed this series of webinars and gave appreciation for speakers and participants in disseminating ideas as a form of scientific development and community service. Faculty of Fisheries and Marine Sciences Undip is ready to collaborate in building environmentally friendly and sustainable coastal ecosystems.

At the end of the event, Woro Yuniati, MSc as the moderator delivered a take home message that the IMTA system is a cultivation method with an ecological ‘zero-waste system’ approach by utilizing organisms based on trophic levels in the food chain. The use of multi-species in cultivation with the IMTA system has been proven to increase the efficiency of ponds, which in turn can increase pond productivity and ultimately increase the economic income of farmers.

Implementation of the IMTA system can be successful by considering the suitability of the site, the types of local organisms available and the seasonal calendar.
