The sales figures of antimicrobial (AM) drugs for farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in Norwegian aquaculture was high, although varying, in the period 1981-1994. Since then the usage in these species has been negligible in spite of the huge increase in the biomass fish produced. This is mainly due to the introduction of efficient vaccines against the m...

The recent interest in using insects as food and feed is based on their capacity to be a sustainable alternative other protein sources. When farmed mini livestock, the question raised whether they are ‘sentient beings’ (self-conscious)? In researching this topic, problem that humans often expect animals have same subjective experience we do (anthropomorphic) consider themselves centre of univer...

The chromosome constitution of Dybowski's sika deer was studied on the basis of 15 samples obtained from farmed stock maintained in an enclosure. The diploid chromosome number was 2n=68, 2n=67 and 2n=66. The constitutive heterochromatin (C-bands) was located in the centromeric regions of all acrocentric chromosomes. Metacentric chromosomes were C-negative. Chromosomes of three pairs proved to b...

Female adult specimens of the pennellid copepod Peniculus minuticaudae Shiino, 1956 were collected from the fins of two species of monacanthid fishes, threadsail filefish (Stephanolepis cirrhifer) and black scraper (Thamnaconus modestus), cultured in floating cages in Japan. These collections represent the first records of P. minuticaudae from farmed marine fishes as well as the first records o...

In the United States, approximately 1.3 billion fish are raised in off-shore and land-based aquaculture systems each year for food, making them the second-most commonly farmed animal domestically, following broiler chickens. The majority of farmed fish are subject to overcrowded and restrictive conditions, which, if unchecked, can quickly deteriorate water quality, cause severe stress, and resu...

in this study, length-weight relationship of three populations of fingerling roach (rutilus rutilus caspicus), wild, farmed and mix were investigated with the fish reproduce in the center of the proliferation of bony fish syjeval harber. in order to check the length-weight, 587 sample fish by hand sachook during the release into the sea. minimum and maximum total length of respectively 17.14 (f...

Biochemical and qualitative evaluation of the supernatant of urine from hydrated farmed ostriches (Struthio camelus) indicated that the urine was comparable to that described by other workers. The disparities obtained between the biochemical constituents in the present and previous studies were partly attributed to the state of hydration influenced by climatic factors. Results of the cytologica...

Biosurfactant (BS) production by Bacillus tequilensis KM15 is investigated using fish processing wastes as medium components. Bocha (B) and Rohu (RR) scales are selected cost-effective substrates for BS optimized together with pH, the incubation period (IP), inoculum size (IS) response surface method (RSM). RSM model has demonstrated following optimum conditions production: 4% each, 2%, at pH 8...
