Chapter 19 - Circular bioeconomy for stress-resilient fisheries and aquaculture

Abstract

Global fisheries have shown impressive growth during the past three decades, contributing to the huge opportunities in freshwater, brackish water, inland saline, and coastal aquaculture, as well as culture-based /reservoir and capture fisheries. However, approximately 35% of fish and seafood produced gets lost or wasted at some point along the supply chain, in addition to the considerable wastes generated by society. Sustainable use of bioresources and efficient natural resource management is of utmost importance for human welfare and livelihood improvement of resource-poor. The best way of sustaining bioresources is to utilize them in such a manner and at a rate that it does not cause a long-term decline of biological diversity aligned with their multiplication, thereafter maintaining its potential to fulfill the needs and aspirations of present and future generations. Circular bioresource efficiency, involving smart and efficient use of resources, minimizes and repurposes waste and can lead to stress-resilient fisheries and aquaculture. This can be beneficial in terms of not only through local resource-use efficiency, healthier aquatic ecosystems and more resilient economies but also through opportunities to create more value at the local level, livelihood improvement, and employment generation. This book chapter highlights all stages of fisheries and aquaculture encompassing eco-design of energy-efficient and environmental protective production systems and products and circular economy–based utilization of generated wastes and byproducts in an integrated manner for making fisheries and aquaculture stress-resilient and sustainable for livelihood improvement and future generations.
