Bacterial spoilage is an important reason causing freshness deterioration of fish during postmortem storage. The aim this study mainly to investigate the role bacteria in and degradation inosine 5′-monophosphate (IMP) as well nucleotide derived values chilled sturgeon (hybrid, Acipenser schrenckiid × Huso dauricus) fillets using a microbial reduction pretreatment. During storage at 4 or -1 °C, ...
the aim of the present study was determination of reference values of blood serum enzymes of huso huso. descriptive study. 18 male and 18 female huso huso was studied. blood samples were obtained from caudal vein of 18 males and 18 females and the levels of enzymes were measured by an autoanalyzer. parametric t- test and pearson correlation test. results of measurements for total samples are as...
The effect of native probiotic (mixtures of Lactococcus lactis and Lactococcus lactis ) on growth rate and some of the hematological and immune system parameters of juvenile Huso huso were investigated.. One hundred fifty six Huso huso individual with average weight of 2.92±0. 16gr ± SD were fed by company Biomar diet (protein: 47%, lipid: 16%, carbohydrate:3/2%) that add probiotic to level of...
Aim The restoration of the extinct Adriatic population Beluga sturgeon, an iconic species with economic and traditional relevance, is a priority in upcoming conservation strategies but it must not occur without deep prior knowledge on current diversity distribution. We defined informed criteria for reintroduction Italian rivers by analysing its contemporary ancient based multi-markers approach....
(عنوان) یادگیری زمان-مکان در فیل ماهی (huso huso) جوان (نام دانشجو) احسان ابراهیمی مطالعه حاضر با هدف بررسی رفتار یادگیری زمان- مکان غذا و همچنین فعالیت پیش بینی تغذیه در فیل ماهیان (huso huso) جوان انجام شد. این آزمایش در دو مرحله به صورت فردی و گروهی انجام گرفت. مرحله اول گروه های پنج تایی از فیل ماهیان در تانک های 2000 لیتری (200×200×50سانتی متر) و مرحله دوم با 8 عدد فیل ماهی در 8 عدد تا...
اکوسیستمهای دریایی و ساحلی فراهمکنندهی مزایا و خدمات مختلفی برای انسان هستند که آبزیپروری دریایی به عنوان یکی از مهمترین این خدمات به شمار میرود. سواحل جنوبی دریای خزر به ویژه سواحل مازندران از پتانسیل مناسبی جهت توسعهی آبزیپروری دریایی برخوردار است. هماکنون 9 مزرعه پرورش ماهی در سواحل مازندران با ظرفیتهای تولید مختلف درحال بهرهبرداری است. در این مطالعه با استفاده از مدل آبزیپروری د...
A phylogenetic hypothesis is presented illustrating relationships among 23 extant sturgeon species based on nucleotide data from five mitochondrial genes (cytochrome b, NADH5, control region, 16S, and 12S). The tree supports our previous hypotheses regarding relationships among species of Acipenser and Huso. The introduction of Scaphirhynchus and Pseudoscaphirhynchus to the analysis does not ch...
effect of dietary free l-lysine on growth, food intake, and muscle composition of beluga juveniles were investigated over 6 weeks. control diet lysine content was 2.1% of dry matter (4.4% of dietary protein). three experimental diets were prepared by adding lysine (0.5, 1 and 1.5%) to control diet to obtain diets containing 2.6, 3.1 and 3.6% of dry matter lysine (corresponding to 5.5, 6.6 and 7...
