Enteromyxum leei has been identified as the causative agent of emaciation disease in a wide range marine fish hosts. In this study, we aimed to determine effect parasitic infection species on starry flounder that were cultured aquaculture farms Jeju island Korea. As mortality olive Paralichthys olivaceus because E. increased, some attempted culture Platichthys stellatus, an alternative. Myxospo...

Abstract On the basis of in situ analysis sturgeon condition within Lower Danube River, aim was to carry out a research that would complement results obtained from monitoring and ultrasonic tagging methods. Thus, DNA samples were taken selectively each ultrasonically tagged specimen order determine whether or not there is possibility hybridization between species Acipenser stellatus Huso huso ....

BACKGROUND Use of plant resources and ecosystems practiced by indigenous peoples of Mesoamerica commonly involves domestication of plant populations and landscapes. Our study analyzed interactions of coexisting wild and managed populations of the pitaya Stenocereus pruinosus, a columnar cactus used for its edible fruit occurring in natural forests, silviculturally managed in milpa agroforestry ...

Until 1994, only scarce research existed on these plants; however the worldwide interest in this novel fruit crop is evident, as numbers of pitaya-related publications have grown rapidly, especially during the past decade .There is a big confusion about both botanical and commercial names and there is a need to clear this point. herein, we attempt to review existing knowledge on the taxonomy, b...

One species of the genus Tanypus Meigen, 1803, T. punctipennis Meigen, 1818 was previously recorded from Japan. Herein Tanypus nakazatoi sp. nov. is described and figured based on all life stages. Tanypus kraatzi (Kieffer, 1913) is recorded for the first time from Japan, and all stages are redescribed and figured. Tanypus formosanus (Kieffer, 1912) sensu Niitsuma (2001) is recognized as T. kraa...

The family Gasteropelecidae is composed of three genera and eight species. This study shows that Thoracocharax cf. stellatus has 2n = 52 chromosomes for both sexes. The five males studied showed 8 metacentric, 16 submetacentric, 4 subtelocentric, and 24 acrocentric chromosomes; the seven females showed only one submetacentric chromosome, belonging to pair 11, and one extra acrocentric chromosom...

A new gregarious braconid parasitoid wasp of Euphorinae, Meteorus stellatus Fujie, Shimizu & Maeto sp. nov. , is described from the Ryukyu Islands in Japan, based on an integrative taxonomic framework. The phylogenetic position species within Meteorini was analyzed DNA fragments mitochondrial cytochrome c oxidase 1 (CO1) and nuclear 28S rDNA genes. recovered as a member versicolor compl...

Some haematological variables including Red Blood Cells (RBC), White Blood Cells (WBC) differential counts, Haemoglobin (Hb), Haematorite (HCT), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were measured in 90 stellate sturgeon juveniles Acipenser stellatus (1-2 years old) and 90 Persian sturgeons Acipenser persicus (1-2...

this study was investigated the effects of dietary estradiol-17? (e2) on growth, body composition and blood indices in acipenser stellatus. fish (40.9 ? 1.1 g average initial weight; n = 60 per group) were fed with three different diets containing 0 (control), 25 and 50 mg kg-1 dietary estradiol contents to apparent satiation for seven months. the results suggested that growth rate were decreas...
