Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. Although the production of fish and vegetables is the most visible output of aquaponic units, it is essential to understand that aquaponics is the management of a complete ecosystem that includes three major groups of organisms: fish, plants and bacteria. This document provides recommendations o...

Pituitary gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play central roles in regulating gametogenesis and the production of gonadal hormones, in fish as in other vertebrates. Pituitary gonadotropins are composed of two non-covalently associated polypeptide subunits, which must be glycosylated, folded, and assembled as a heterodimer to be biologically active. Si...

T he supplies of fish in the world's vast oceans once seemed inexhaustible. Not any more. In the past three decades, production and consumption of fish have risen so dramatically that the world's wild fisheries may fall victim to their own success. Meanwhile, the growing aquaculture industry has attempted to fill the gap between supply and demand. But as the global appetite for fish continues t...

Introduction In recent years, the welfare of fish has received increasing attention and attempts have been made to control welfare in farmed fish. This may be achieved through regulation of management practices, including stocking density, etc. Skin lesions in farmed fish are an important challenge to the fish farmer. Fish with ulcers, fin erosions or impaired eyes are very conspicuous among th...

introduction: fish mycobacteriosis is caused by the non-tuberculous mycobacteria. infected fish are normally the primary source of infection, although non-tuberculous mycobacteria can be found in the environment. the present study was designed to  investigate the few recently found suspected cases of mycobacteriosis in iranian ornamental fish tanks.   materials and methods: pathological specime...

In rheumatoid arthritis (RA) benefit from non-steroidal anti-inflammatory drugs (NSAIDs) is mediated through inhibition of the cyclo-oxygenase enzyme, thereby decreasing production of the 2 series prostaglandins (PGs). The lipoxygenase enzyme is intact, however, allowing leucotriene (LT) production, e.g., LTB4 (an inflammatory mediator). Treatment with evening primrose oil (EPO) which contains ...

The study assessed adoption of improved fish pond management technologies among fish growers in Benue State, Nigeria. Stratified, purposive and simple random sampling techniques were used in selecting 221 respondents. Primary data were collected using structured questionnaire. Data collected were analysed using both descriptive such as frequency distribution tables and inferential statistics su...

If there ever was a major improvement in human life in the last millennium, it may well have been the green revolution of the twentieth century. The massive use of fertilizers, pesticides and improved seeds and livestock brought an enormous increase in agricultural production, more than enough to feed the population in the developed regions of the world such as Europe and North America. For the...

BACKGROUND Crohn disease (CD) is associated with osteoporosis and other extraintestinal manifestations that might be mediated by cytokines from circulating (peripheral blood) mononuclear cells (PBMCs). Fish oil rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) reduces disease activity in patients with CD with raised laboratory markers of inflammation and in healthy subjects alt...
