Nephrocalcinosis in farmed salmonids: diagnostic challenges associated with low performance and sporadic mortality.

Disease conditions that involve multiple predisposing or contributing factors, or manifest as low performance and/or low-level mortality, can pose a diagnostic challenge that requires an interdisciplinary approach. Reaching a diagnosis may also be limited by a lack of available clinical profile parameter reference ranges to discriminate healthy fish from those affected by specific disease conditions. Here, we describe our experience investigating poorly performing rainbow trout () in an intensive recirculation aquaculture, where reaching a final diagnosis of nephrocalcinosis was not as straightforward as one would wish.

Early immune response of two common carp breeds to koi herpesvirus infection.

Economic importance of common carp (Cyprinus carpio L.) increases every year. Viral diseases are major threat for carp aquaculture and cause significant economic losses.

Carp edema virus infection associated gill pathobiome: A case report.

Understanding disease aetiology and pathologic mechanisms is essential for fish health evaluation. Carp edema virus (CEV) is the causative agent of a disease (CEVD) responsible for high mortality rates in both wild and cultured common carp Cyprinus carpio. Inspection of two carp specimens from a pond with high fish mortality revealed CEV infection in both the host and its ectoparasite (Argulus foliaceus).

Cyanobacteria Contributes to the Severity of Fish Diseases: A Study on Spring Viraemia of Carp.

Fish are exposed to numerous stressors in the environment including pollution, bacterial and viral agents, and toxic substances. Our study with common carps leveraged an integrated approach (i.e.
