seal bomb
Noun: A seal bomb is a small explosive device designed to be used underwater. Its primary purpose is to produce a loud noise and shockwave to deter marine mammals, particularly seals and sea lions, from approaching or interfering with fishing operations and gear. It physically resembles a firecracker but is engineered for aquatic use.
The term is used specifically in the context of fisheries management and marine wildlife deterrence. It refers to the physical object itself and the practice of deploying it.
- Fishermen sometimes use seal bombs to protect their catch from being stolen by sea lions.
- The use of seal bombs is regulated to minimize harm to marine life.
- A seal bomb detonates underwater, creating a concussive sound meant to scare animals away.
- As a deterrent tool: The device is not intended to cause physical injury but to exploit an animal's aversion to loud, unexpected noises, making an area seem hazardous.
- Regulatory context: Discussions around seal bombs often involve debates on fishery protection, animal welfare, and the potential for auditory damage or behavioral disruption in marine species.
- Acoustic Deterrent Device (ADD): A broader category of devices that use sound (including non-explosive sounds) to deter marine animals.
- Marine mammal deterrent: A general term for any method or device used to keep marine mammals away from a specific area or activity.
- Underwater firecracker (descriptive synonym)
- Acoustic harassment device (in a broader, more technical sense)
- Marine mammal scare charge
The term seal bomb is highly specific. It does not refer to: * A bomb designed to kill seals. * Any explosive device used on land. * A brand name or a type of military ordnance.
Its meaning is confined to its role as a non-lethal, acoustic deterrent in aquatic environments.
- a small explosive device (resembling a firecracker) that is used underwater in order to frighten mammals away from fishing grounds
