Ecosystem-based fisheries management and the precautionary approach in the Indian Ocean regional fisheries management organisations.

The Indian Ocean hosts a wide range of living resources including fish stocks. Marine resources contribute significantly to economies and livelihoods, and seafood is a major source of protein in Indian Ocean nations. Fisheries resources in the Indian Ocean have started showing symptoms of depletion. Several regional fisheries management organisations (RFMOs) have been established for sustainable management of the fisheries resources in the Indian Ocean region. These RFMOs were created at different times with various particular mandates, and in some cases prior to the emergence of contemporary scientific concepts and legal approaches to marine environmental governance. In this article, eight such RFMOs are studied to determine the implementation of ecosystem-based fisheries management (EBFM) and the precautionary approach (PA), which are now widely accepted norms of fisheries management and international law. This article argues that there is a mismatch between the legal and governance frameworks, and the fisheries science and management.

Eyes in the sea: Unlocking the mysteries of the ocean using industrial, remotely operated vehicles (ROVs).

For thousands of years humankind has sought to explore our oceans. Evidence of this early intrigue dates back to 130,000BCE, but the advent of remotely operated vehicles (ROVs) in the 1950s introduced technology that has had significant impact on ocean exploration. Today, ROVs play a critical role in both military (e.g. retrieving torpedoes and mines) and salvage operations (e.g. locating historic shipwrecks such as the RMS Titanic), and are crucial for oil and gas (O&G) exploration and operations. Industrial ROVs collect millions of observations of our oceans each year, fueling scientific discoveries. Herein, we assembled a group of international ROV experts from both academia and industry to reflect on these discoveries and, more importantly, to identify key questions relating to our oceans that can be supported using industry ROVs. From a long list, we narrowed down to the 10 most important questions in ocean science that we feel can be supported (whole or in part) by increasing access to industry ROVs, and collaborations with the companies that use them. The questions covered opportunity (e.g. what is the resource value of the oceans?) to the impacts of global change (e.g. which marine ecosystems are most sensitive to anthropogenic impact?). Looking ahead, we provide recommendations for how data collected by ROVs can be maximised by higher levels of collaboration between academia and industry, resulting in win-win outcomes. What is clear from this work is that the potential of industrial ROV technology in unravelling the mysteries of our oceans is only just beginning to be realised. This is particularly important as the oceans are subject to increasing impacts from global change and industrial exploitation. The coming decades will represent an important time for scientists to partner with industry that use ROVs in order to make the most of these 'eyes in the sea'.
