Significant decline in abundance of greenland halibut Reinhardtius hippoglossoides matsuurae the North-West Pacific is one reasons for development methods this species age determination using different age-recording structures. The study based on recommendations Northwest Atlantic Fisheries Organization (NAFO) and International Council Exploration Sea (ICES). Underestimation found records scale...

Fish skins constitute an important fraction of the enormous amount of wastes produced by the fish processing industry, part of which may be valorized through the extraction of gelatins. This research exploited the extraction and characterization of gelatins from the skin of three seawater fish species, namely yellowfin tuna (Thunnus albacares), blue shark (Prionace glauca), and greenland halibu...

16S rRNA molecules in a microbial strain can differ due to nucleotide variation between their genes. This is a typical trait of fast-growing bacteria to cope with different niches. We investigated characteristics of 16S rRNA genes in Vibrio splendidus strain PB1-10, from the normal flora of Atlantic halibut. Sequencing of 16S rRNA gene clones detected 35 variable positions in a total of 13 diff...

BACKGROUND microRNAs (miRNAs) are implicated in regulation of many cellular processes. miRNAs are processed to their mature functional form in a step-wise manner by multiple proteins and cofactors in the nucleus and cytoplasm. Many miRNAs are conserved across vertebrates. Mature miRNAs have recently been characterized in Atlantic halibut (Hippoglossus hippoglossus L.). The aim of this study was...

Introduction: Indian childhood cirrhosis is a chronic liver disease usually seen in paediatric age group and is unique to the Indian subcontinent. The definitive causative factor for the disease is not found till now but excess copper ingestion has been associated with it.Case presentation: An Indian origin one and half year old premorbidly normal male child presented with history of gradual di...

A genetic linkage map has been constructed for Atlantic halibut on the basis of 258 microsatellites and 346 AFLPs. Twenty-four linkage groups were identified, consistent with the 24 chromosomes seen in chromosome spreads. The total map distance is 1562.2 cM in the female and 1459.6 cM in the male with an average resolution of 4.3 and 3.5 cM, respectively. Using diploid gynogens, we estimated ce...

Several humoral immune factors were studied in a group of cultured halibut (Hippoglossus hippoglossus L.). The serum protein and IgM concentration was comparable to levels seen in other teleost species. A strong antibody activity against TNP-BSA was observed but not against other antigens tested. Lysozyme and anti-protease activity was detected and showed variable heat sensitivity. Unlike the a...
