Long‐term shifts in pikeperch, Sander lucioperca, diet composition in a changing reservoir

open access: yesJournal of Fish Biology, EarlyView.
Abstract As a significant piscivorous predator, the pikeperch (Sander lucioperca) plays a critical role in regulating aquatic ecosystems. Understanding its size‐related feeding behaviour is thus vital for assessing its impact. To evaluate its role in the ecosystem, stomach content analysis provides useful insights into predator–prey dynamics.

Characterization data of gilthead sea bream (Sparus aurata) IGF-I receptors (IGF-IRa/Rb)

open access: yesData in Brief, 2016
In this data article we describe the coding sequence of two IGF-IR paralogues (IGF-IRa and IGF-IRb) obtained from gilthead sea bream embryos. The putative protein architecture (domains and other important motifs) was determined and, amino acid sequences ...

Application of Environmental DNA for Monitoring Red Sea Bream Iridovirus at a Fish Farm

open access: yesMicrobiology Spectrum, 2021
Red sea bream iridoviral disease (RSIVD) causes high economic damage in mariculture in Asian countries. However, there is little information on the source of infection and viral dynamics in fish farms. In the present study, the dynamics of RSIV in a fish

Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen Fillets

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia (Oreochromis niloticus) and mandarin fish (Siniperca chuatsi). ISKNV is a genogroup of Megalocytivirus pagrus1, along with RSIV and TRBIV, and their recent listing as WOAH ...

Ghrelin and Its Receptors in Gilthead Sea Bream: Nutritional Regulation [PDF]

open access: yesFrontiers in Endocrinology, 2018
Ghrelin is involved in the regulation of growth in vertebrates through controlling different functions, such as feed intake, metabolism, intestinal activity or growth hormone (Gh) secretion. The aim of this work was to identify the sequences of preproghrelin and Ghrelin receptors (ghsrs), and to study their responses to different nutritional conditions

St John's Wort (Hypericum perforatum) Oil on Immune Response, Growth Performance and Bacterial Resistance Against Lactococcus garvieae Pathogen in Rainbow Trout (Oncorhynchus mykiss)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,

Complete mitochondrial genome of yellowback sea bream Evynnis tumifrons [PDF]

open access: yesMitochondrial DNA Part B, 2016
The complete mitochondrial genome of the Evynnis tumifrons was 16 616 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The overall base composition of E. tumifrons was A 27.05%, T 26.42%, C 29.45% and G 17.07%. Phylogenetic tree construction indicated that Evynnis tumifrons was most closely related to

Development and Validation of a Viability RT‐qPCR Assay for Detecting Infectious Spring Viraemia of Carp Virus (SVCV)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Spring viremia of carp virus (SVCV) is a contagious pathogen associated with significant mortality and economic losses in freshwater aquaculture. Although reverse transcription quantitative PCR (RT‐qPCR) enables rapid detection, it does not distinguish between infectious and non‐infectious viral particles, which may lead to overestimation of ...

Impact of Diets Containing Plant Raw Materials as Fish Meal and Fish Oil Replacement on Rainbow Trout (Oncorhynchus mykiss), Gilthead Sea Bream (Sparus aurata), and Common Carp (Cyprinus carpio) Freshness

open access: yesJournal of Food Quality, 2018
The present study aimed to evaluate whether the total or high substitution of fish meal (FM) and fish oil (FO) by sustainable plant raw materials (plant meal and oils) in long-term feeding for rainbow trout, gilthead sea bream, and common carp can result
