Like other cetaceans, killer whales are exposed to actual or potential threats from a variety of human activities that can adversely affect their habitat and prey or the animals directly. These may be common across populations or limited to local populations and groups. Examples include habitat degradation (including chemical pollution and coastal development), cetacean watching, interactions with marine traffic and interactions with fisheries.
The species is frequently reported interacting with fisheries, with many populations having learned to take catches from fishing gear (a behavior termed “depredation”). This can make the whales more vulnerable to entanglements (already a threat) and potentially a target for direct action by fishers who may lose gear and catch. In addition to whales being killed or damaged by vessel strikes, vessel interactions may also involve probable play behavior by killer whales that can result in damage to or sinking of sail boats (usually via the rudder) as seen in recent years in off the Iberian Peninsula; again
with the potential that sailors take direct action.
More ‘indirect’ threats can include the effects of chemical pollution on reproduction and survivorship; shifts in distribution from optimal areas due to disturbance (e.g. tourism, increased vessel traffic or development) and/or changes in prey availability and distribution (e.g. due to overfishing).
The ability of killer whales to adapt and develop new behaviors in response to human activities may lead to additional rather than reduces conflicts with humans, with both socio-economic and ecological impacts. While mitigating these conflicts primarily becomes a priority for local actors, the lack of knowledge on their mechanisms (causes and consequences) often prevents effective solutions, ensuring both the conservation of killer whales and the viability of the human activities involved, to be identified.
You have to consult with the event organizer:
The objective of this Workshop is to develop a framework to guide the investigation, understanding and mitigation of both direct and indirect interactions between human activities and killer whales.
Focus will be on:
Reviewing the main types and cases of documented interactions between killer whales and human activities, their drivers (ecological and/or anthropogenic) and impacts (positive and/or negative);
Examining priorities with regard to the science needed to inform for mitigation when interactions involve serious threats to killer whale conservation; discussing the role of researchers in the management of these interactions (and interactions with managers and affected persons) by inter alia sharing experiences on the approaches that have provided effective solutions.
The objective will then be to develop a framework document (potentially for journal submission) that:
synthesizes identified interactions that have a high likelihood of affecting killer whale conservation at local or broader levels;
considers larger-scale questions such as ‘are fisheries altering, though resource removals or new feeding opportunities, the diet and the ecological predatory role of killer whales in their ecosystem? or ‘are industrial activities (e.g. tourism and marine traffic) excluding killer
whales from optimal habitat thus adversely affecting their dynamics?’;
and strategies to involve all major stakeholders in collaborative efforts towards mitigation and co-existence.

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all of the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside of it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers), both for Windows and for MAC users.
Despite our very best efforts to allow anybody to adjust the website to their needs, there may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to
