Lift net

Lift nets, also called lever nets, are a method of fishing using nets that are submerged to a certain depth and then lifted out of the water vertically. The nets can be flat or shaped like a bag, a rectangle, a pyramid, or a cone. Lift nets can be hand-operated, boat-operated, or shore-operated. They typically use bait or a light-source as a fish-attractor.[1] Lift nets are also sometimes called "dip nets", though that term applies more accurately to hand nets.[2]

Types

Portable hand lift nets

Portable hand lift nets are small lift nets operated manually. They usually have a rigid frame which is attached to a long pole. They are used primarily to catch fish and crustaceans, and may be submerged just below the water surface or close to the bottom. A person using hand lift nets usually operate it from the shore, on bridges, and from harbor walls.[3]

Shore-operated stationary lift nets

Stationary lift nets are larger than hand lift nets and are attached permanently to a shore-built structure. Lifting the nets may be done by hand through the use of counterweights, or they may use mechanized winches. Bait or a strong source of light is placed in the middle of the net. They are typically placed near beaches or riverbanks.[4]

Boat-operated lift nets

Boat-operated lift nets are lift nets operated from water vessels. They may be lifted up by hand or by mechanical winches. They usually utilize several long poles attached to one side of the boat or surrounding the boat. Bait or a strong source of light is used to attract the fish.[5]

It's the bees.<|endoftext|>And bees.<|endoftext|>Well, it's a hard drive for bees
gollark: Done.
