The present invention relates to a harvesting system for harvesting zooplankton or mesopelagic fishes and a method of harvesting zooplankton or mesopelagic fishes.

The present disclosure relates to imaging for determination of crustacean physical attributes. An image of a shell of a live crustacean is captured and processed to determine a physical attribute of the live crustacean. In an embodiment a characteristic of a pattern indicative of moult stage of the live crustacean is detected, from the captured image. Multiple images may be used in some embodiments, including images of different types such as visible spectrum images, infrared spectrum images, and/or ultraviolet spectrum images.

A structurally sound circular crab trap suitable for commercial crab fishing, designed to be stacked one inside another to facilitate transport.

A structurally sound circular crab trap suitable for commercial crab fishing, designed to be stacked one inside another to facilitate transport.

A collapsible crab trap is provided with a centrally-located bait feeder made of wire mesh material. The trap and bait feeder are movable between a collapsed configuration and an assembled configuration. When in a collapsed configuration, it is easy to store or transport. The centrally-located bait feeder is constructed in such a manner that the crabs cannot remove an entire piece of bait from the bait feeder. Another feature of this crab trap is that the two side panels are weighted along their upper edges to positively open the side panels when on the ocean bed for the catching of crabs. These weighted side panels also provide a stable placement of the crab trap in strong moving currents.

Minnow traps suitable for trapping minnows may include a pair of spaced-apart, minnow-accessible side trap compartments. A minnow-accessible front trap compartment and a minnow-accessible rear trap compartment may be disposed between the side trap compartments. The front trap compartment and the rear trap compartment may be disposed in spaced-apart relationship to each other. At least one central bait compartment may be disposed between and communicate with the side trap compartments and between and communicate with the front trap compartment and the rear trap compartment. The at least one central bait compartment may be configured to contain a supply of bait.
