A floatation device. The floatation device may comprise: at least two float portions and one or more fasteners. The two float portions may be opposing halves of a floatation float configured to form a float when combined. The one or more fasteners may be aligned and positioned on the outer side of the two float portions, such that, when the fasteners engage with each other, the two float portions form as a float. The fasteners may be strap fasteners. Accordingly, the float portions may fasten together on a fishing line after mating the fasteners. To increase the strength of the fastening the devices, an adhesive fastener may be included on the contact surfaces of the float portions. Each float portion may also comprise a recess and a projection for mating or engaging. The floatation device is particularly useful as a floating support for seines and commercial fishing nets.
