“…Standardized fisheries independent surveys could be a simple solution to overcoming this issue. Electronic observation systems still have limitations, especially regarding bycatch identification, but promising results indicate this system could also be a useful tool to improve both monitoring and data collection (Ames et al, 2007;Ruiz et al, 2014).…”

a b s t r a c tRecently, declining populations of several pelagic shark species have led to global conservation concerns surrounding this group. As a result, a series of species-specific banning measures have been implemented by Regional Fishery Management Organizations (RFMOs) in charge of tuna fisheries, which include retention bans, finning bans and trading bans. There are both positive and negative aspects to most management measures, but generally, the positive aspects outweigh the negatives, ensuring the measure is beneficial to the resource and its users in the long term. Banning measures are a good first step towards the conservation of pelagic shark species, especially since they improve conservation awareness among fishers, managers and the public. Measures that impose total bans, however, can lead to negative impacts that may jeopardize the populations they were intended to protect. The majority of pelagic shark catches are incidental and most sharks die before they reach the vessel or after they are released. The legislation set out by RFMOs only prevents retention but not the actual capture or the mortality that may occur as a result. Managers should be fully aware that the development and implementation of mitigation measures are critical for a more effective conservation strategy.

“…While no smalltooth sawfish were observed, the catch and safe release of a loggerhead sea turtle, Caretta caretta, was recorded by both the EM system and observer. The EM system was used to record commercial shrimp vessel operations during six trips, encompassing 1,733 h of video over 94 sea days, with a certified fishery observer also being pres-with varying levels of success (Ames et al, 2007;Kindt-Larsen et al, 2012;Ruiz et al, 2015;Stanley et al, 2015;van Helmond et al, 2015van Helmond et al, , 2017Bartholomew et al, 2018;van Helmond et al, 2019;Briand et al 1 ). Van Helmond et al (2019) provides a comprehensive review of global EM projects and programs, including 12 fisheries that currently have some form of electronic monitoring as part of their regulatory process.…”

“…The exploration of EM in trawl fisheries is approached with caution, as they involve a high amount of catch in relatively short periods of time, and discerning catch composition can be highly problematic for this reason (Ruiz et al, 2015;van Helmond et al, 2015). Applicability of EM to shrimp trawls in particular is potentially even more problematic, as they target animals with low biomass, making it difficult to identify, measure, and count individuals, which are common goals of monitoring programs (van Helmond et al, 2015(van Helmond et al, , 2017(van Helmond et al, , 2019.…”

“…However, other forms of electronic monitoring including, for example, video and sensor monitoring have seen limited adoption (Dunn & Knuckey, ). While fisheries such as the tropical tuna purse‐seine fishery have begun testing the reliability of these camera systems and compared their accuracy to on‐board observer data, the results have been varied (Ruiz et al., ). Cost‐efficient and‐effective MCS measures across all of these categories still need to be developed, supported and expanded to provide statistically significant sampling that can track not just species‐level impacts, but community and ecosystem level impacts and the necessary inputs to control and enforcement activities.…”

Empowering high seas governance with satellite vessel tracking data

Between 1950 and 1989, marine fisheries catch in the open‐ocean and deep‐sea beyond 200 nautical miles from shore increased by a factor of more than 10. While high seas catches have since plateaued, fishing effort continues to increase linearly. The combination of increasing effort and illegal, unreported and unregulated (IUU) fishing has led to overfishing of target stocks and declines in biodiversity. To improve management, there have been numerous calls to increase monitoring, control and surveillance (MCS). However, MCS has been unevenly implemented, undermining efforts to sustainably use high seas and straddling stocks and protect associated species and ecosystems. The United Nations General Assembly is currently negotiating a new international treaty for the conservation and sustainable use of biodiversity beyond national jurisdiction (BBNJ). The new treaty offers an excellent opportunity to address discrepancies in how MCS is applied across regional fisheries management organizations (RFMOs). This paper identifies ways that automatic identification system (AIS) data can inform MCS on the high seas and thereby enhance conservation and management of biodiversity beyond national jurisdictions. AIS data can be used to (i) identify gaps in governance to underpin the importance of a holistic scope for the new agreement; (ii) monitor area‐based management tools; and (iii) increase the capacity of countries and RFMOs to manage via the technology transfer. Any new BBNJ treaty should emphasize MCS and the role of electronic monitoring including the use of AIS data, as well as government–industry–civil society partnerships to ensure critically important technology transfer and capacity building.
