A gauge for measuring the size of a clam includes a C-shaped body that has a base that extends from a first axial end to a second axial end, a first leg extending from the base proximate the first end and a second leg extending from the base proximate the second end. A gap extends between the first leg and the second leg. The gap having a predetermined magnitude selected to match minimum size limitations for keeping a clam. The gauge being removably securable to a shaft of a clam rake,

A scallop harvesting bag used for harvesting scallops. The scallop harvesting bag may clip to a swimsuit allows for the use of both hands to hold and put scallops into this bag. The scallop harvesting bag has a rigid to semi-rigid throated opening to facilitate insertion of harvested scallops into the bag. The bag is attached to a bottom end of the throated opening and has an extraction closure defined along at least one edge of the bag. The bag may be formed of a mesh material to facilitate cleaning sand and debris from the harvested scallops contained therein.

Embodiments described herein relate generally to systems that can include an optical sensor configured to generate image data associated with a set of aquatic animals, a memory, and a processor operatively coupled to the memory and the optical sensor. The processor can be configured to receive the image data associated with the set of aquatic animals, determine a set of characteristics associated with the set of aquatic animals based on the image data using a machine learning model, and classify each aquatic animal in the set of aquatic animals based on the set of characteristics using the machine learning model. The processor further configured to count at least a subset of the aquatic animals based on the classification.

Dredging is a very destructive method of harvesting scallops as it causes significant damage to marine habitats and contaminates scallops with grit. The invention described herein provides a scallop trap comprising: a chamber having an opening; a ramp, for directing scallops to the opening, having a first portion disposed outside of the chamber and a second portion adjacent to the opening, and in use the second portion is disposed above the first portion; and an attractant disposed, in use, above the second portion of the ramp. In this way, scallops can be captured more sustainably without excessive damage to their habitat and without introducing excess grit to the scallop.

A crawfish harvest system and method of harvesting crawfish from a crawfish pond, without entry into the pond by personnel or boats. A crawfish trap deployment and retrieval unit is positioned by a crawfish pond. One or more crawfish traps are attached to a main line, which is engaged with the deployment and retrieval unit and runs into the crawfish pond and around one or more turn points in the pond, forming an endless loop of main line. The crawfish traps can be deployed into and retrieved from the crawfish pond by the deployment and retrieval unit pulling the main line, without personnel, boat or other entry into the pond.
