System for Reducing the Number of Predator Fish

ABSTRACT The system includes a capsule member made from a material which is not dissolvable in water but is dissolvable in the digestive fluids of a predator fish. The capsule contains a material which, following ingestion by a predator (game/sport) fish, results in death of the predator fish. A connecting member is secured to the capsule, and is adapted to be secured to a prey (bait) fish such that when the prey fish is released in a body of water, such as a lake, in the vicinity of the predat

Methods for the Conversion of Fish Waste from Aquaculture Systems to Methane Via a Modified Uasb Reactor.

A process for treatment of sludge made up of saline organic solids or organic waste produced in a saltwater or brackish aquaculture system is described. The process includes use of a modified reactor, operating under anaerobic conditions, which yields methane from the digestion of the saline organic solids. Modification of a traditional reactor to include a packing substrate provides for saline waste digestion not previously known. Additionally provided is a process for producing methane from th

Method and System for Identifying Shellfish

The invention relates to a method which allows identifying shellfish by- forming a mark (6) on the carapace or shell of the animal (5) to be identified by means of applying a laser beam (4). By means of this method it is possible to identify crustaceans, mollusks or any other animal provided with a carapace, shell or outer skeleton. A logotype or trademark, an expiry date, capture date, a bar code or any other legend can thus be marked on the surface of the shell or of the carapace of the animal

Controlled Biosecure Aquatic Farming System in a Confined Environment

The present invention relates generally to improving the bio security and the stability of intensive recirculating aquatic farming systems for instance by hard and soft sensing and control of the pH and alkalinity in an aquatic farming system and in response thereto optimal pH and alkalinity normalisation and nitrogen removal. This control is aimed at reduce toxicity in particular nitrogen toxicity on the living organism and at preventing biosystem collapse. Yet more particularly the invention c

Use of No and No Donors for Terminating Dormancy in Invertebrates

The present invention relates to a method for terminating dormancy in an invertebrate, wherein said invertebrate is brought in contact with nitric oxide and/or a nitric oxide donor. The method can be used in pest management of unfavourable species, in eliminating dormant stages of aquatic invertebrates in ballast water in promoting termination of dormancy in beneficial species and /or in stimulating production of live food in aquacultures.

Method of Protecting a Surface from Biological Fouling

The present invention relates to a method of protecting a surface from biological fouling. The present invention finds particular application in the protection of the surface of objects that are used in aquatic environments, particularly marine environments. The present invention also relates to kits for use in the methods of the present invention.
...

Feed Additives for Aquaculture and Aquarium Culture

The present invention refers of feed additives for aquaculture and aquarium culture. These additives comprise the amino acid, 1-methyl-L-tryptophan, or its isomers with the objective of improving the attractiveness of feeds used in aquaculture and aquaria for fish, as well as other aquatic organisms, under culture conditions. Therefore, this invention has applications in the agriculture-food industry.

Active Wildlife Ladder

An unpowered device for providing an aquatic wildlife ladder for giving passage upstream and downstream for animals and fish. An example comprises an upright or substantially vertically mounted housing containing one or more substantially helical surface(s) over which water may flow, providing a continuous water path and preferably easy means of entrance and exit. As water flows through the device it is adapted to turn a central shaft, so that electrical or other useful power may be generated. T

Apparatus and Method for Influencing Fish Swimming Behaviour

An enclosure, method and apparatus for influencing the swimming behaviour of fish is disclosed. The enclosure defining a space within which the fish can swim, said enclosure having a series of light output members disposed along a path, said light output members being operable to provide a moving visual stimulus along the path by output of light in sequence from the series of light output members thereby to influence the swimming behaviour of the fish.

Sex Control in Shrimp and Prawn Aquaculture

Description A novel approach to isolate the Androgenic sex hormone (AH) from the crustacean freshwater prawn and marine shrimp using in vitro glandular secretion of the AH from AH-producing Androgenic glands. Yields in commercially important, female-superior, sexually dimorphic shrimp can be dramatically improved by using all-female population (reaching 20%-30% larger body size than males) generated by mating normal genetic females with genetic females that have been "sex-reversed" into "neomale
...
