A protector device includes a plurality of pairs of multi-pronged elements. Each pair of multi-pronged elements includes a first multi-pronged element having a first C-shaped element that has a first straight section, a first end forming a first end spike, and a second end forming a second end spike, and a first connecting element attached to and perpendicular to the first C-shaped element. Each pair of multi-pronged elements also includes a second multi-pronged element including a second C-shaped element connected to the first connecting element of the first multi-pronged element, the second C-shape element having a second straight section, a third end forming a third end spike, and a fourth end forming a fourth end spike, and a second connecting element attached to and perpendicular to the second C-shaped element.

Method for cultivating paralarvae of the common octopus, Octopusvulgaris up to the settlement thereof (benthic phase), based on a diet of prey containing the caprellids Pfttisica marina and CaprelIa equilibra and/or gammarids of the genus Jassa spp. Factors such as light conditions, water renewal and temperature, inter alia, are optimized to obtain maximum paralarvae survival.

A fish egg incubator including a housing containing a reciprocating mechanism, at least one connector assembly associated with the reciprocating mechanism, at least one perforated containing assembly for holding the fish eggs located at least partially below a water surface and which is associated with the connector assembly where in the reciprocating mechanism periodically moves the least one perforated containing assembly in the water in order to move the eggs in the at least one perforated containing assembly.

A fish delousing installation includes a warm water source, and a fish slide for fish to slide down. The fish slide has a fish inlet, a fish outlet, and a slide length defined therebetween. A plurality of shower nozzles are in communication with the warm water source and are positioned to shower the fish with warm water as the fish slide from the fish inlet to the fish outlet.

An object of the present invention is to provide oysters which are highly safe and not contaminated with microorganisms including viruses and bacteria, the oysters moreover being fresh and having high nutritional value, and being available throughout the year in the same state as oysters from the in-season period. Provided is a method for cultivating oysters on land, the method including growing oyster larvae into adult shellfish in seawater containing deep-sea water in a water tank through feeding microalgae cultured in seawater containing deep-sea water to the oyster larvae. Specifically, provided is a method for cultivating oysters on land, the method including growing oysters in a suspension system including seedling collectors suspended vertically or horizontally on ropes by allowing deep-sea water to continuously flow through the system without stagnation or repeatedly allowing deep-sea water to stagnate and continuously flow through the system without stagnation at a given interval at a seawater temperature of 10 C. to 30 C. for 5 months to 18 months.

A buoyancy system is for a fish pen. The fish pen has an enclosure for keeping fish confined in the fish pen, the enclosure being secured to an inner flexible buoyancy body floating on a water surface. The buoyancy system has an outer buoyancy body on the outside of the inner buoyancy body. The inner buoyancy body is attached to the outer buoyancy body with a mooring so that the outer buoyancy body and the inner buoyancy body move independently of each other relative to waves.

Examples of the disclosure provide for an apparatus for actively restoring and promoting marine life. Said apparatus includes a mounting component and a receiver component. Said mounting and receiving components are capable of mechanically joining with each other. Said mounting component provides a base for stable attachment of a living sessile organism. Said receiver component provides stable anchoring for said mounting component. Various embodiments of said apparatus function to facilitate propagation, protective transport and efficient out planting of said organisms in a submerged marine environment.

A method of growing shellfish is disclosed. The method comprises obtaining a support tray (I) with recesses (7) where at least some of the recesses (7) incorporate means adapted to create a deliberately formed alphanumeric, written or pictorial mark on the shellfish as it grows. Shellfish spat are attached to at least some of the recesses (7) and the tray (I) is placed in water so that the spat grow into substantially mature shellfish within the recesses (7). The spat each grow generally in the shape of their respective recess (7) so that the mark is created on the shellfish as it grows.
