Conservation Management Plans (CMPs) are an important conservation initiative of the IWC. They provide a framework for countries within the range of vulnerable cetacean populations (known as range states) to work together, and in collaboration with other relevant stakeholders, to protect and rebuild those populations.
A coalition of conservation organisations supporting and promoting the International Ranger Federation to build a network of well-supported, professional, and capable rangers, who can act effectively as custodians of the natural world. It has produced numerous guidelines and standards of relevance to professionalizing the ranger work-force, including a Code of Conduct, ranger competences, and a document on how rangers support delivery of 30×30. There are 8 organizations URSA can be linked with (for filtering purposes).

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.
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.
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.
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.
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.
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.
Most reports of collisions between whales and vessels involve large whales, but all species can be affected. Collisions with large vessels often go unnoticed and unreported. Animals can be injured or killed and vessels can sustain damage. Serious and even fatal injuries to passengers have occurred involving hydrofoil ferries, whale watching vessels and recreational craft.
Anthropogenic ocean noise is identified as one of the priority threats in the Strategic Plan of the IWC Conservation Committee. In 2018, the IWC agreed a Resolution that recognised the increasing concern over ocean noise, and clarified next steps to better understand and manage the threat. In 2022 the IWC endorsed a Workplan on Anthropogenic Ocean Noise. The Scientific Committee is also undertaking research on the impact of noise on cetaceans, and the effectiveness of different approaches to reduce exposure.
