Seabird deterrents are devices or methods used to prevent seabirds from interacting with fishing gear, particularly longlines, or other marine structures. The primary goal of these deterrents is to reduce incidental seabird mortality, which can be a significant conservation concern for many seabird populations worldwide.

One common type of deterrent is the "tori line," a brightly colored rope towed from the stern of a fishing vessel. This line, often equipped with streamers or flags, is designed to create a visual barrier that scares seabirds away from the baited hooks as they are deployed. Another approach involves using weighted lines that sink the bait quickly below the surface, making it less accessible to diving seabirds.

Some deterrents focus on altering the visual cues associated with fishing. For example, "bird scaring lines" with streamers can be deployed to deter birds from approaching the vicinity of the vessel during baiting operations. Additionally, acoustic deterrents, such as underwater sound emitters, have been explored, although their effectiveness and potential impact on other marine life are still subjects of research.

The effectiveness of different deterrents can vary depending on the target seabird species, the fishing method, and environmental conditions. Research and development continue to refine existing methods and explore new technologies to improve seabird conservation in the face of fishing activities. Compliance with regulations and best practices for using deterrents is crucial for their successful implementation.
