The evaluation of the economic and environmental return on investment of modern fish screens in this project offers several significant benefits for both biodiversity conservation and agricultural businesses. By replacing outdated and ineffective trash racks with modern fish-protection screens, native fish and debris can be prevented from entering irrigation infrastructure, resulting in multiple positive outcomes. One of the key benefits is the protection of millions of native fish, reducing their loss from waterways and contributing to the preservation of biodiversity. Additionally, farmers can experience tangible benefits such as reduced labor and maintenance costs due to decreased debris in their irrigation systems. Through rigorous documentation and communication of the environmental and economic advantages of modern screens, this project aims to improve farmer awareness and understanding of the technology, inform decision-making processes, and guide the integration of screening in conservation and fisheries management policies. Ultimately, the widespread adoption of modern fish screens will contribute to the enhancement of rivers, fish populations, and agricultural productivity, creating a win-win situation for both the environment and farming communities.
