Provided herein are compositions that are useful for attracting fish, conch, crustaceans, or any combination thereof. Also provided herein are processes of preparing the compositions, methods of using the compositions for improving the biosecurity of an environment, and methods of using the composition for attracting fish, conch, crustaceans, or any combination thereof.

A system for remediation of perfluoroalkyl substances (PFASs) has a multicity of ?-cyclodextrins (?-CDs) and/or modified ?-CDs combined with a vehicle additive, and a delivery device. Modified ?-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the ?-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the ?-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.

A fish calling device for attracting predatory fishes by mimicking all sensory characteristics of a prey including appearance, sound and smell is disclosed. The device is configured to spray water into a waterbody around the device in a circular or a semi-circular pattern, thereby mimicking the appearance of a group of bait fishes. The water is sprayed to create the sound of a bait fish trying to escape from the predatory fishes when sprayed onto the waterbody. A scent bag is attached to the sprayer for dispersing/dispensing a smell through the water sprayer thereby mimicking the smell of a bait fish. Thus the device activates three senses of the predatory fishes including sight, hearing and smell for attracting them while fishing/competition.

A device for macerating bait, making chum, or both is provided. The device has a main housing having a top openable end and a closed bottom openable end; a removable lid attachable to the top openable end, wherein the removable lid comprises at least a fluid flow hole configured to, when placed in a fluid and towed behind the vessel, port the fluid to flow through the housing through bottom openable end and through the top openable end; a push rod disposed through the removable lid; a concentric cutting member attached to the push rod at a lower end of the push rod, wherein the concentric cutting member comprises a series of blades that are intersecting and have cutting edges on a top and bottom of the blades.

A method of macerating bait is also provided.

A method of preparing imitation fish eggs is provided wherein granules of cross-linked polyacrylamide are hydrated to form globules that can be placed in netting that is twisted and tied to form imitation egg sacs. The egg sacs can then be attached to a fishing hook and used for bait. The globules can be made any desired color by including food coloring or other suitable dye.

A hydrogel fishing bait has a fish attractive scent infused into a water swollen hydrogel. The hydrogel can be a copolymer of at least one water miscible monomer and a cross-linking monomer. The hydrogel can be a terpolymer of hydroxyethyl methacrylate (HEMA), acrylamide, and a crosslinking monomer. The hydrogel terpolymer can be prepared in the shape of a fish or other fish attracting shape. The scent can be an amino acid, protein, fatty acid, sugar, or any combination thereof, and can be from a natural or artificial source. The hydrogel can be filled with a fiber, mesh, or matrix material. The hydrogel can be an interpenetrating polymer network. The hydrogel can be biodegradable. The hydrogel baits when fully hydrated on their surface do not stick to each other.

Compositions and methods useful for fishing are described. In particular, compositions which include one or more fish attractants and which combine several advantageous properties, including moldability at ambient temperatures, sustained release of attractant(s), and ability to resist casting forces due to increased wet strength, are described. These advantages are achieved by combining a polymer such as a cellulose ester, a plasticizer, one or more fish attractant food sources, and optionally one or more fillers. The compositions may include up to 50% attractants, rendering them an effective bait material for attracting fish, crustaceans, other aquatic creatures such as marine mammals, mink, beaver, nuisance pests such as insects, rodents, and coyotes or game species such as deer and bear.

A bait cutting and crab measuring apparatus that combines a bait cutting device with a crab measuring device. The apparatus includes a bait-cutting channel and a crab-measuring panel. The bait-cutting channel includes first wall, a second wall, a base panel, a first plurality of segment cuts, and a second plurality of segment cuts. The crab-measuring panel can be used to visually and standardly measure various types and sizes of crabs. The first wall and the second wall can be used as a protective handle from the claws of crabs when measuring a crab with the crab-measuring panel. The base panel provides a platform for the bait that is placed inside the bait-cutting channel. The first plurality of segment cuts and the second plurality of segment cuts allow the user to cut the bait inside the bait cutting channel at an angle allowing the bait to spin when on a hook.

A bait cake for a crustacean trap, the bait cake comprising a mixture of animal collagen, water, gelatin, gelling agents, fish meal, and fish oil, molded and cured into a cylindrical cake; a method of preparation of a bait cake which preserves the attractiveness of the bait cake to crustaceans, and a method of attracting crustaceans to a trap using the bait cake of the invention.

A bait holder includes a multi-purpose lid that has a sliding portion operable to both cut and enclose bait within a bait container.
