ABSTRACT The ornamental pet trade has emerged as one of the most important pathways for introduction non‐native aquatic species. In last two decades, freshwater crayfish have become a popular group, with numerous populations established through this way, including some North American red swamp Procambarus clarkii (Girard, 1852). Whilst routes aquaculture‐derived been identified molecular methods and historical documents, obtaining traceability in market is often more challenging. We analysed...
From 22 May to 10 June 2011 massive mortality of Prussian carp Carassius gibelio was observed in alluvial Lake Řehacˇka close the Elbe River Czech Republic. More than 1400 kg dead fish were collected and no other species affected. Further molecular cytogenetic investigation (n = 232) revealed that Rˇehacˇka population consisted exclusively gynogenetic triploid females. The causative agent identified by means electron microscopy as a herpesviral hematopoietic necrosis virus (Cyprinid...
The private stocking of ornamental crayfish in garden ponds was discussed previous studies, but there is a lack detailed analysis for better understanding this introduction pathway. Czech Republic one leading EU countries trade with and are popular among people. keepers the country were interviewed by self-administered questionnaire to gather data about principal characteristics information breeding that interest conservation managers. Besides releasing into ponds, alarming illegal behavior...
Hybridization and polyploidization are important evolutionary processes whose impacts range from the alteration of gene expression phenotypic variation to triggering asexual reproduction. We investigated fishes Cobitis taenia-elongatoides hybrid complex, which allowed us disentangle direct effects both processes, due co-occurrence parental species with their diploid triploid hybrids. Employing morphological, ecological, RNAseq approaches, we molecular determinants polyploid forms. In...
Sailfin catfish indigenous to South America are very popular ornamental fish, having previously been introduced many regions outside their native range. Two species, namely Pterygoplichthys disjunctivus and P . pardalis , illegal but widespread in Indonesia. They have formed self-sustaining populations, exploited for feeding of domestic animals locally human consumption. Also possible hybrids the two mentioned species were recorded. The surveyed populations considered established which...
Trade with marine species as ornamentals is an important sector of the international pet trade. The vast majority these are collected from wild and one top supplying countries Indonesia. Detailed evidence on trade resources in Indonesia lacking or it hardly accessible. Moreover, exploitation ornamental seems to be mostly uncontrolled. This study presents detailed characteristics such for Indonesia, including offered species, their sizes, prices, conservation status, based data information...
Morphological, cytogenetic and molecular genetic identification of two specimens Carassius langsdorfii from the upper Elbe basin is given. Probably, species was introduced by accident with commercial fish imports. Potentially, this may be harm to native species.
The pet trade with decapod crustaceans has been considered one of the main pathway introduction these animals worldwide. As leading markets in this regards are Czech Republic, Germany and USA. Central Asia is not perceived as an important market ornamental crustaceans. Despite assumption, we found at least 16 species freshwater shrimp, crayfish crab pet-traded Republic Kazakhstan, largest country region. Considering computed risk assessment, origin particular species, their availability on...
Cherax quadricarinatus (von Martens) (Decapoda: Astacidea: Parastacidae) is commercially exploited and has been intentionally introduced to various tropical subtropical countries.Once established in the wild, it frequently becomes invasive.In Indonesia, this crayfish native only southern part of Papua Province.Cherax produced semi-intensive farms for food as well ornamental purposes on most Indonesian territory.We present here first record species from Java, where formed at least two feral...
The pet trade in aquatic organisms is a significant source of non-indigenous species introductions. In comparison with ornamental animals, unintentionally transported invertebrate assemblages are easily overlooked by traders and keepers. Moreover, hitchhiking detection identification difficult even for experts. densities “hitchhikers” aquaria may be relatively higher than those the wild. These phenomena known freshwater but poorly studied marine ones. We found 17 non-ornamental invertebrates...
Fish usually have a simple body shape and many morphological characters can be easily obtained by 2-dimensional image analysis. Measuring errors are often analyzed using data from several researchers or repeated measurements, but the testing of accuracy repeatability based on different methods has rarely been examined. Here we report comparison manual measurements Proma 150D digital calipers computer-assisted analysis in LUCIA software to evaluate both suitability images for exploration fish...
A desirable attribute of novel antimicrobial agents for bacterial diarrhea is decreased toxicity toward host intestinal microbiota. In addition, gut dysbiosis associated with an increased risk developing cancer. this study, the selective growth-inhibitory activities ten phytochemicals and their synthetic analogs (berberine, bismuth subsalicylate, ferron, 8-hydroxyquinoline, chloroxine, nitroxoline, salicylic acid, sanguinarine, tannic zinc pyrithione), as well those six commercial...
