The world fisheries and aquaculture supplied about 142 million tons of fish in 2008, of which 115 million tons was used as human food, providing around 17 kg (live weight equivalent) per capita/per person. Aquaculture accounted for 46% of total food fish supply, a slightly lower proportion with respect to that reported in the past. Huge amount of fish and other marine organisms were eliminated ...

Microbes play an important role in the degradation of fish products, thus better knowledge of the microbiological conditions throughout the fish production chain may help to optimise product quality and resource utilisation. This paper presents the results of a ten-year spot sampling programme (2005-2014) of the commercially most important pelagic fish species harvested in Norway. Fish-, surfac...

The accelerated growth of finfish aquaculture has resulted in a series of developments detrimental to the environment and human health. The latter is illustrated by the widespread and unrestricted use of prophylactic antibiotics in this industry, especially in developing countries, to forestall bacterial infections resulting from sanitary shortcomings in fish rearing. The use of a wide variety ...

A simple, rapid PCR assay for the identification of Renibacterium salmoninarum in Atlantic salmon (Salmo salar L.) tissues detected DNA extracted from between 4 and 40 bacterial cells. PCR was at least as sensitive as culture when it was used to identify subclinically infected fish experimentally challenged with R. salmoninarum. However, PCR identified much higher numbers of kidney tissue and o...

Skeletal deformities cause severe economic losses in the aquaculture industry due to the reduced market value of the affected fish. The banded cichlid (Heros severus) is an ornamental cichlid native to the Amazon region. In the summer 2011 during clinical investigation on 750 severum of 5 ornamental fish farms in Karaj and Tehran, Iran, a two-year-old severum having deformity in dorsal and anal...

The fishing industry is deeply dependent on complex and high quality diets consisting of dry feed, vitamins and micro/macro-elements. The suitable dose of each essential nutrient is different based on the fish species, their age and physiological conditions. In this study, the effects of two recommended doses of riboflavin (20 and 30 mg vitamin per each kg dry feed) on growth, hematological and...

The biologic effects of the oil shale industry on caged rainbow trout (Oncorhynchus mykiss) as well as on feral perch (Perca fluviatilis) and roach (Rutilus rutilus) were studied in the River Narva in northeast Estonia. The River Narva passes the oil shale mining and processing area and thus receives elevated amounts of polycyclic aromatic hydrocarbons (PAHs), heavy metals, and sulfates. The ef...

India has a long coastal line of about 8000 km includes 13 main land states and 5 Union territories which comprises significant biodiversity. The east and west coast of India continues to be a large fishing ground in the south Asian region and is one of the largest marine product nations in the world. During the period of 2009, India’s annual fish landings are about 3.16 million tonnes [1]. Fis...
