A floating Fishermen's island for growing 10,000 tons of fish and seafood within multiple water-filled ring-tube fishery, including auxiliary fish growing pools and recreation boating, fishing and water sports amenities. The Island comprising equally spaced radial Island member array made of molded plastic emerging from a floating Island center with cylindrical ends pivoted to island center arms-ends and to island outer boat docking segments. Vertical poles extending island radial members supporting walk-over-water fishermen's deck segments above water-filled ring-tube fishery for fishing from fish pools underneath. Connection cable connects each island radial member underneath the ring-tubes, with cable to anchor the island to seabed. A walk over water elevated deck connected with bridges over poles multiple radial island docking for large service boats, sail boats and speed boats comprising multiple radial island boat docking segments, service boat docking segments allow loading and unloading reef for multiple service, sail and motorboats.

A coral ring mount device and method for the propagative culture of sessile benthic marine organisms (for example, stony corals) employing either a ring, washer or threaded nut or similar as a propagule mount upon which the coral is set in order to attach, grow and overgrow within a coral nursery system. In the preferred embodiment of the invention, once the coral is grown onto the ring mount and to its requisite size and condition, the ring mount becomes the washer through which passes a screw to secure the ring and coral to the seafloor.

Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

Large capacity fish and seafood growing aquaculture comprises multiple floating at sea concentric transparent torus tubes with central barge equipped with air compressor, electronic controller and anchored to seabed. Floating level above sea level of aquaculture torus tube is controlled by floating level sensor input triggering compressor to inflatable helical balloon wrapped around aquaculture tube and commanded by electronic controller. Water level in each tube is controlled by air pressure actuated valves. Each tube consists of four torus tube segments which are constructed of strong molded structural helical pipe wrapped into torus shape with molded resilient helical strip wall and with sealed helical inflatable balloon to control tube buoyancy level with connection to four vertical pipes for external rapid insertion and removing fish and food into and from the tubes. Cabled means connected to seabed.

A fishing hook snare system includes an elongated main body member that is constructed from a material suitable for prolonged exposure to an underwater environment. A plurality of snares are disposed along the main body. Each of the snares including a shape, size and construction material for engaging fishing hooks and entangling the same. A positioning unit having a plurality of weighted elements is in communication with the main body. The positioning unit having a tether and anchors for selectively positioning the main body a discrete distance from the bottom surface of the body of water or on the surface of the body of water.
