The genus Edwardsiella (family Hafniaceae), includes species: E. tarda, E. hoshinae, E. ictaluri, E. piscicida, E. anguillarum. The species Edwardsiella tarda is widespread, being isolated from many animals that live in freshwater or marine waters, especially fish, but also from wild or domestic...

In intensive aquaculture, quantitative research on bait particles has important theoretical and practical significance for reducing breeding costs and realizing intelligent feeding, and can effectively reduce environmental pollution caused by excessive bait. However, the current methods based on...

An outbreak of nodular gill disease (NGD) in farmed rainbow trout Oncorhynchus mykiss (Walbaum, 1792) was recorded in Ladoga Lake (Karelia, north-western Russia) in Spring 2020. The disease was characterised by typical clinical signs including asphyxiation, distended opercula, loss of activity and...

Purpose: Diplectanum is a life-threatening metazoan infecting the gills of Sea bass Dicentrarchus labrax causing a wide-ranging extensive economic loss in the aquaculture sector. This study has focused on verifying the most effective non-toxic dose of the Neem (Azadirachta indica) and...

This study tested the efficacy of a pond polyculture intervention with farming households in northern Zambia. Longitudinal data on fish consumption and the associated nutrient intake of households (N = 57) were collected over a six-month period (September 2019-March 2020). One group of people...

Transcription activator-like effector nuclease (TALEN) plasmids targeting the channel catfish gonadotropin-releasing hormone (cfGnRH) gene were delivered into fertilized eggs with double electroporation to sterilize channel catfish (Ictalurus punctatus). Targeted cfGnRH fish were sequenced and base ...

Optimal smoltification is crucial for normal development, growth, and health of farmed Atlantic salmon in seawater. Here, we characterize miRNA expression in liver to reveal whether miRNAs regulate gene expression during this developmental transition. Expression changes of miRNAs and mRNAs was...

The aim of this study is evaluating the performance of Tilapia-do-nilo (Oreochromis niloticus) fingerlings (GIFT lineage) fed with a diet containing dehydrated fish protein (DPP) and commercial feed (RC) during the early stage of development. Dehydrated fish protein was produced from tilapia fillet ...

The aim of this study is to determine the egg and larval growth performance of brown trout (Salmo trutta sp.) at a constant high water temperature under commercial farm conditions. Eggs were taken from 450 female broodstocks with an average weight of 5.09±0.29 kg. The eggs placed in the incu-bators ...

Studies of fish growth response to changes in dietary protein and energy content are often conducted with fish fed to apparent satiation or at fixed percentages of their body mass. Such designs result in simultaneous changes in protein and non-protein energy intake, thereby failing to distinguish...
