Guidelines for the Safe and Humane Handling and Release of bycatch small cetaceans in fishing gear

The largest cause of small cetacean mortality is bycatch, the incidental capture of non-target species such as dolphins, marine turtles, and seabirds. An estimated 300,000 cetaceans are killed in commercial fisheries each year, therefore preventing fisheries bycatch should be a top priority to ensure the conservation of species or populations. However, the threat of bycatch has yet to be eliminated, so these guidelines provide a practical tool to minimize its impacts by guiding fishers in the safe release of small cetaceans entangled in their gear, thus decreasing the risk of further injury or stress and increasing the chances of post-release survival.

UNITED FOR THE CONSERVATION OF MARINE MEGAFAUNA IN SAN JOSE, LAMBAYEQUE

This initiative was born from the vision of David Sarmiento, IMARPE field observer and renowned 2023 Leatherback Champion, who decided to go beyond his job. David realized that, in order to achieve effective marine conservation, it was important to build bridges with artisanal fishers, based on mutual trust and respect. Using everyday tools such as local radio stations, social media, and training spaces, David forged an authentic connection with the crews of fishing boats in the cove of San Jose (Lambayeque). His approach combined scientific expertise with a deep human sensitivity. By listening, valuing, and exchanging ideas with the fishers, he enabled them to take the lead in bringing about change. Today, they are the ones who share recordings of rescues, reflections, and data on marine megafauna. Experience shows that conservation is most effective when it stems from strong human relationships and committed local leadership, generating sustainable learning and trust among stakeholders.

GOOD PRACTICES FOR THE HANDLING AND RELEASE OF SENSITIVE SPECIES INTERACTING WITH THE TUNA PURSE SEINE FISHERY

In 2016, three fishing companies carried out a pre-assessment to establish a Marine Stewardship Council program. In 2017, two more joined, launching the Fishery Improvement Project toward MSC certification. Member companies, including NIRSA, Jadran Group, Servigrup, Eurofish, Tri Marine, Marbelize, Manacripex, Pacifictuna, and Tunaquick, have worked with the support of the Ecuadorian government and WWF to improve fishery management and reduce environmental impact.

TUNACONS promotes sustainable fishing in the Eastern Pacific by optimizing tuna yields through scientific research. It also trains the sector and supports the reduction of ecosystem impacts.

Since October 2017, a code of good practices for handling and releasing bycatch has been implemented, aimed at captains and crew. Key actions include:

– 59 vessels recording data on bycatch reduction and incidental catches
– Collaboration in a manta ray tagging program
– Training sessions on IATTC resolutions, sensitive species handling, and external evaluations.

Protecting endangered Olive Ridley Turtles and guiding fishers along Odisha Coast, India through Mobile technology

The Fisher Friend Mobile Application (FFMA) by MSSRF, in collaboration with Qualcomm and INCOIS, supports India’s coastal fishers with real-time data on sea conditions, fishing zones, navigation, and more, all in local languages. Recently, FFMA introduced a No Fishing Zone alert to protect endangered Olive Ridley Turtles along Odisha’s coast. Using geo-fencing, it marks critical turtle habitats—including the Gahirmatha Sanctuary and key river mouths—and triggers audio message and vibrating when fishers approach within 200 meters, even without internet. This offline feature helps fishers avoid fines and supports turtle conservation by preventing unintended fishing in restricted zones. Since its launch, the No Fishing Zone alert has prevented over 6,866 intrusions, aligning conservation with sustainable fishing and supporting fisher livelihoods and safety. FFMA’s technology ensures that fishers benefit from safer, eco-friendly practices while contributing to the preservation of biodiversity in India’s coastal zones

ASCOBANS Monitoring Cetacean Bycatch: An Analysis of Different Methods Aboard Commercial

This report reviews, describes and evaluates the different monitoring options that are available for obtaining counts of the number of cetacean bycatches that occur in European fisheries. Three methods were adjudged able to obtain these data: self-reporting by fishers, atsea observers, and remote electronic monitoring (REM) systems with CCTV. Of these, only the data collected by at-sea observers or REM can be collected independently of the fishers and only REM allows later verification of the bycatch events as often as required. Therefore, in this report these two methods are more fully described and compared against each other in terms of ability to collect the required data and of the costs associated with running a cetacean monitoring programme.

A description of the different components associated with electronic monitoring was also presented as there has often been confusion about what constitutes electronic monitoring and electronic recording and why a verification tool is necessary. Only a REM system with integrated satellite tracking, fishing activity sensors, and closed-circuit television cameras (CCTV), was considered a full remote electronic monitoring system with verification.

IWC Marine Debris

The increasing amount of debris in the world’s oceans has become a major cause for concern. There are many different types of marine debris. It travels freely and does not recognise national boundaries, which means international collaboration is essential to any attempts to address the issue effectively.

IWC Entanglement response initiative

Whale disentanglement is complex and dangerous. It involves small boat handling, ropes under high tension, sharp blades and panicked wild animals. There are safety and legal protocols, and a number of detailed assessments must be made including condition of the animal, nature of the entanglement, weather and conditions, and available resources.

The IWC brings together the leaders of established national disentanglement programmes. They share their knowledge and expertise to develop best practice protocols which are used to train nominees and build professional and effective response capacity in other parts of the world where entanglements occur.

ASCOBANS Cost-benefit Analysis for Mitigation Measures in Fisheries with High Bycatch

Bycatch is a major conservation and welfare issue for cetaceans in European waters. Harbour porpoises and common dolphins are frequently reported to be bycaught in static nets (gillnets and entangling nets) and trawls. Despite European legislation to monitor and mitigate cetacean bycatch in fisheries where it has a negative impact on the conservation status of a species, bycatch still occurs at high rates in several fisheries in the ASCOBANS Agreement Area. The lack of compliance by some countries has resulted in legal challenges from the European Commission for implementation of the required measures.

There are two main parts covered in this report. The first part reviews different mitigation measures (acoustic deterrent devices, porpoise alerting devices, reflective nets, acrylic echo enhancers, lights and various technical modifications and changes to fishing practices) that have been trialled in the ASCOBANS region. The cost of implementation and pros and cons of each method are discussed in detail in the relevant sections.

The second part of the report reviews alternative fishing methods to replace static nets (i.e. gillnets and entangling nets). The cost of implementation, and pros and cons of the different gears, are discussed in depth in the relevant sections.

Fishing operations – Guidelines to prevent and reduce bycatch of marine mammals in capture fisheries

The Guidelines to Prevent and Reduce Bycatch of Marine Mammals in Capture Fisheries were produced by FAO in response to the request from the Committee on Fisheries at its Thirty-third Session in 2018 to develop technical guidelines on this subject, and are directed at decision-makers, planners, managers and all those involved in developing and implementing policy and technical interventions which relate to the bycatch of marine mammals in fisheries.The guidelines were drafted and developed through a series of activities undertaken by FAO, including the Expert Workshop on Means and Methods for Reducing Marine Mammal Mortality in Fishing and Aquaculture Operations and the Expert Meeting to Develop Technical Guidelines to Reduce Bycatch of Marine Mammals in Capture Fisheries. They outline options for marine mammal bycatch reduction through the application of technical measures, including: spatial closures, the use of acoustic deterrents or alerting devices, modifications to fishing gear, changes in fishing operations and other strategies. The document refers to policy instruments and institutional frameworks that support the implementation of the guidelines and the conservation of marine mammals, in addition to awareness raising, communication and capacity-building actions, together with the special requirements of developing States. Finally, the guidelines address the future research and development needs for the prevention and reduction of marine mammal bycatch in capture fisheries.
