A remote operated vehicle for selectively harvesting a target species in an aquatic environment is disclosed. The vehicle may include a chassis defining a central channel and being configured to hold a plurality of attachments mounted to the chassis. The plurality of attachments may include at least one thruster configured to propel the vehicle in the aquatic environment, and at least one electronics containment unit configured to store one or more electronic devices for controlling an operation of the vehicle. The vehicle may also include a containment unit connected to the chassis and configured to store the target species during harvesting, and at least one stunning device configured to stun the target species. The vehicle may further include at least one suction device positioned at a rear portion of the chassis and being configured to generate flow in a direction extending through the channel to cause the target species to flow into the containment unit.
