Guide for implementing ecological intensification of aquaculture systems ; Guide de mise en oeuvre de l'intensification écologique pour les systèmes aquacoles

Abstract

International audience ; The rapid development of aquaculture in the world has offered, depending on the species and territory, examples of "success stories" but has sometimes also led to social or environmental crises. The issue of food security in 2050 requires improving technology and practices while moving toward practices of "sustainable aquaculture". These changes promote territorial integration and need to be better recognized and mastered. The framework proposed by ecological intensification of agricultural systems offers an opportunity to redefine objectives for aquaculture by promoting ecological mechanisms to maintain or increase production in these systems. It thus consists of diversifying pathways to sustainable aquaculture and promoting the strengthening of ecological functions while considering sociological and governance constraints.Thus, the objective of this guide, the fruit of an interdisciplinary research project among French, Brazilian, and Indonesian partners, is to propose pathways for implementation of ecological intensification in aquatic ecosystems of aquaculture. To do so, it supplies (i) many potential objectives based on concepts of agro-ecology, ecosystem services, and processes for co-constructing eco-innovations; (ii) assessment tools (indicators); and (iii) examples of experiments in four types of contrasting aquaculture systems.This guide is addressed to a wide public: representatives of supply chains or aquaculture producers, representatives of territorial governments or administrations, and more generally, all members of NGOs or associations interested in development of aquaculture and/or setting up of integrated territorial projects, but also researchers and students as well as all actors wishing to implement ecological intensification, including outside the field of aquaculture.
