Hirudiculture is the culture, or farming , of leeches in both natural and artificial environments. This practice drew the attention of Parisian scientists and members of the French Zoological Acclimitation Society in the mid-to-late 19th century as a part of a larger interest in the culture of fish and oysters . [1] Leech culture was seen as a solution for growing demand for medicinal leeches throughout the world.

The use of leeches for medicinal purposes, or hirudotherapy , has been revived by contemporary medicine. [2] Continue reading “Hirudiculture”

Fort San Lucian

Fort San Lucian ( Maltese : Forti San Lucjan ), Also Known As St Lucian Tower ( Maltese : Torri ta ‘San Lucjan ) or Fort Rohan ( Maltese : Forti Rohan ) is a broad bastioned watchtower and polygonal strong in Marsaxlokk , Malta . The original tower was built by the Order of Saint John between 1610 and 1611, being the second of six Wignacourt towers . An artillery batterywas added in around 1715, and the complex was upgraded into a strong in the 1790s. In the 1870s, the fort was rebuilt by the British in the polygonal style.

Gyrodactylus salaris

Gyrodactylus salaris , commonly known as salmon fluke , [1] is a tiny monogenean ectoparasite which lives on the body surface of freshwater fish. [2] This parasite-like parasite has been implicated in the Atlantic salmon populations in the Norwegian fjords . [3] It also parasitises other species, including rainbow trout . [4] G. salaris requires fresh water , [2] but can survive inbrackish water for up to 18 hours. [5] Continue reading “Gyrodactylus salaris”

Greenfish recirculation technology

Developed in Sweden, the Greenfish recirculation technology is a water purification technology for sustainable aquaculture production in closed indoor freshwater systems. It was developed at Gothenburg University by Björn Lindén in collaboration with Chalmers Associate Professor Torsten Wik , under the supervision of Professor Emeritus Gustaf Olsson at Lund University of Technology. Continue reading “Greenfish recirculation technology”

Global Aquaculture Alliance

Global Aquaculture Alliance ( GAA ) is an international non-profit trade association dedicated to aquaculture . Established in 1997, GAA acts as a voice for responsible aquaculture, working with industry, the NGO community, governments, academia and the investment community to address the challenges and opportunities facing aquaculture, through its Global Aquaculture Advocate magazine and annual GOAL conference. GAA Recognizes That aquaculture is the only sustainable moyen de Increasing seafood supply to meet the food needs of the world’s growing population.

Aquaculture of giant kelp

Giant kelp , Macrocystis pyrifera , has been used for many years as a food source; [1] [2] It contains many compounds such as iodine , potassium , other vitamins and carbohydrates and thus has been used as a dietary supplement . [3] [4] In the beginning of the 20th century, California was harvested as a source for potash . [1] [5] [6] With commercial interest greatly increasing during the 1970s and the 1980s this was primarily due to the production of alginates, and also for biomass production for animal feed. [5] [6] [7] However commercial production for M.pyrifera never became a reality. With the end of the energy crisis and the decline of alginates , the research into farming Macrocystis also declined. [2] Continue reading “Aquaculture of giant kelp”
