The present disclosure relates to a system for managing and monitoring a sensor network that senses pest activity. A plurality of sensor stations may be controlled by the system, such sensor station configured for detecting the presence of pests at a baiting station, or for alerting users to the presence of a pest in a trap, as well as a related system of data collection and data management of pest activity data.

Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

A method of harvesting crustaceans that utilizes a trap and buoy system, each trap being equipped with a digital camera and a light flash mechanism and being electrically connected to a buoy which has a wireless broadcast system to forward images received from the camera wirelessly to a further location that is equipped to receive the wirelessly transmitted image and to display the image to a human user. The method begins with laying out traps in the ocean, in a grid having a first grid spacing. Then for each trap, repeatedly lighting the trap with the flash mechanism and forming an image with the digital camera and sending the image to the further location. Then monitoring the images. Finally, in reliance on the images deciding to begin laying out traps in a grid, having a second grid spacing that is tighter than the first grid spacing, around a particular trap.

A fishing trap handling system for handling fishing traps on a deck of a fishing vessel is provided. The fishing trap handling system comprises a gantry crane type lifting apparatus for being mounted to the fishing vessel. The lifting apparatus is adapted for operation while the fishing vessel is exposed to rough seas. An end effector is mounted to a hoist of the lifting apparatus. The end effector is adapted for easily engaging one of the fishing traps and for holding the fishing trap in a substantially horizontal orientation.

Disclosed are systems and methods of identifying and capturing information about items. In this instance, the systems and methods are focused upon fish. Through the use of the disclosed systems and methods, fish can be tagged and/or the image of the fish can be captured. The information about the tagged and/or image-captured fish can be wirelessly communicated to a remote device. As desired, the information specific to the fish can be combined and uploaded into a database with other relevant information, such as location information, temperature readings, latitude, longitude, date, time, and more.
