TL;DR: An eDNA method to estimate the biomass of common carp using laboratory and field experiments and demonstrates that the distribution of carp eDNA concentration was explained by water temperature, suggesting that biomass data estimated from e DNA concentration reflects the potential distribution ofCommon carp in the natural environment.
Abstract: Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass. We developed an eDNA method to estimate the biomass of common carp (Cyprinus carpio L.) using laboratory and field experiments. In the aquarium, the concentration of eDNA changed initially, but reached an equilibrium after 6 days. Temperature had no effect on eDNA concentrations in aquaria. The concentration of eDNA was positively correlated with carp biomass in both aquaria and experimental ponds. We used this method to estimate the biomass and distribution of carp in a natural freshwater lagoon. We demonstrated that the distribution of carp eDNA concentration was explained by water temperature. Our results suggest that biomass data estimated from eDNA concentration reflects the potential distribution of common carp in the natural environment. Measuring eDNA concentration offers a non-invasive, simple, and rapid method for estimating biomass. This method could inform management plans for the conservation of ecosystems.

TL;DR: The temperature growth range, good splitting ratio (1/10) and virus susceptibility make EPC cells a highly suitable material both for fish pathology and for comparative virology studies.
Abstract: Summary A cell line, named Epithelioma papulosum cyprini (EPC) and originating from carp epidermal herpes virus-induced hyperplastic lesions, was esta blished and has now given rise to more than 80 subcultures. It grows within a wide temperature range (15–33°C), survives between 7 and 10°C for several months without alterations in its further virus susceptibility and growth characteristics, and degenerates at 37°C. Its karyotype is 2n=96. It propagates most of the systemic infection viruses of the fish families Salmonidae, Cyprinidae, Anguillidae and Esocidae, as well as Indiana-type vesicular stomatitis virus. Despite the origin of EPC cells, we were unable to demonstrate the presence of herpes virus in them. Their transformation was reflected in their karyotype (normally 2n=100) and by their growth ability in soft agar medium; monolayer growth, however, was inhibited at a density of 3×106 cells/cm2. The temperature growth range, good splitting ratio (1/10) and virus susceptibility make EPC cells a highly suitable material both for fish pathology and for comparative virology studies.

TL;DR: In this paper, a comparative study of the proteolytic and amylase activities in six species of fish with different nutritional habits was performed, including rainbow trout (Oncorhynchus mykiss), gilthead seabream (Sparus aurata), European eel (Anguilla anguilla), common carp (Cyprinus carpio), goldfish (Carassius auratus), and tench (Tinca tinca).

TL;DR: The data suggest that North American rivers are receiving estrogenic chemicals that are biologically active, as has been reported in Great Britain.
Abstract: Endocrine disrupting chemicals can potentially alter the reproductive physiology of fishes. To test this hypothesis, serum was collected from common carp (Cyprinus carpio) at five riverine location...

TL;DR: Estimation of prey vulnerability to predation by pike, a gape-limited predator, revealed that this increase in body depth resulted in crucian carp reaching a size that provided refuge from predation, however, this change in morphology incurs a cost through an increase in drag when the carp are swimming.
Abstract: In a field experiment where the presence or absence of piscivorous pike (Esox lucius) in ponds was manipulated, the morphology of crucian carp (Carassius carassius) diverged, such that individuals became deeper bodied in pond sections with pike. A laboratory experiment confirmed that the presence of this predator induced a change in body morphology in the carp. Estimation of prey vulnerability to predation by pike, a gape-limited predator, revealed that this increase in body depth resulted in crucian carp reaching a size that provided refuge from predation. However, this change in morphology incurs a cost through an increase in drag when the carp are swimming. Because crucian carp are limited by resources in the absence of piscivores and by the substantial cost of the defensive morph in their presence, phenotypic plasticity should be the optimal strategy for this species.
