Prevalence of red sea bream iridovirus among organs of Japanese amberjack (Seriola quinqueradiata) exposed to cultured red sea bream iridovirus

open access: yesJournal of General Virology, 2013
Red sea bream iridovirus (RSIV) is a representative of the genus Megalocytivirus which causes severe disease to aquaculture fish, mainly in Japan and South-east Asia. However, information to assess the viral kinetics of RSIV in fish is limited since reports on experimental infection by the immersion route, which is the natural infection route, are ...

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Responses of growth, blood health, pro-inflammatory cytokines genes, intestine and liver histology in Red Seabream (Pagrus major) to camelina meal

open access: yesAquaculture Reports, 2022
The current work assessed the inclusion impacts of oilseed camelina meal (CM) as a protein source in red sea bream (Pagrus major) diets. A 45 day assessment period with 180 juveniles (6.47 ± 0.17 g) were allocated in triplicates to 4 experimental groups ...

Preliminary study on heartbeats and swimming behavior of free-ranging fish, red sea bream Pagrus major, measured with newly developed micro data-logger [PDF]

open access: yes, 2003
To estimate the physiological condition or metabolic rate simultaneously with swimming behavior, we recorded a continuous electrocardiogram (ECG) in freely swimming fish, red sea bream Pagrus major, in a net pen during a 24h period.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Mapping the Energetic Costs of Free-Swimming Gilthead Sea Bream (Sparus aurata), a Key Species in European Marine Aquaculture

open access: yesBiology, 2021
Measurement of metabolic rates provides a valuable proxy for the energetic costs of different living activities. However, such measurements are not easy to perform in free-swimming fish. Therefore, mapping acceleration from accelerometer tags with oxygen

The Use of Dietary Additives in Fish Stress Mitigation: Comparative Endocrine and Physiological Responses [PDF]

open access: yes, 2019
In the last years, studies on stress attenuation in fish have progressively grown. This is mainly due to the interest of institutions, producers, aquarists and consumers in improving the welfare of farmed fish.

Divergent survival and viral shedding patterns of red sea bream iridovirus in black sea bream and Japanese sea bass

open access: yesJournal of Fish Biology, EarlyView.
Abstract In open marine aquaculture, rearing diverse fish species in adjacent net pens facilitates the waterborne spread of red sea bream iridovirus (RSIV). This study systematically evaluated the horizontal transmission dynamics of RSIV in black sea bream (BSB, Acanthopagrus schlegelii) and Japanese sea bass (JS, Lateolabrax japonicus) under immersion

Environmental quality and aquaculture systems: Proceedings of the Thirteenth U.S.-Japan Meeting on Aquaculture, Mie, Japan, October 24-25, 1984 [PDF]

open access: yes, 1988
The United States and Japanese counterpart panels on aquaculture were formed in 1969 under the United States-Japan Cooperative Program in Natural Resources (UJNR). The panels currently include specialists drawn from the federal departments most concerned

Cognitive appraisal of environmental stimuli induces emotion-like states in fish [PDF]

open access: yes, 2017
The occurrence of emotions in non-human animals has been the focus of debate over the years. Recently, an interest in expanding this debate to non-tetrapod vertebrates and to invertebrates has emerged. Within vertebrates, the study of emotion in teleosts
