Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Territorial behavior in juvenile red sea bream Pagrus major and crimson sea bream Evynnis japonica

Fisheries Science, 2004
: The territorial behavior of juvenile red sea bream Pagrus major and crimson sea bream Evynnis japonica was examined at Morode Cove, Ehime Prefecture. Four exclusive types of behavior (attack, mutual attack, head down threat and mutual display) and one escaping behavior (fleeing) were observed in both species.

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

Journal 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 ...

Molecular characterization and expression of CD96 in red seabream (Pagrus major)

Fisheries and Aquatic Sciences, 2023
CD96 is a membrane-bound receptor discovered in humans in 1992 that is mainly present in natural killer cells and T cells derived from haematopoietic cells and performs immune functions.

Effect of colored light regimes on the stress response and RNA/DNA ratio of juvenile red sea bream, Pagrus major [PDF]

, 2017
We hypothesized that fish with red-sensitive retina would be stressed by red light and thus inhibited in somatic growth. Red sea bream (Pagrus major) juveniles (total length =3 cm) with red-sensitive retina were chosen to test this hypothesis.

Fish larval nutrition and feed formulation: knowledge gaps and bottlenecks for advances in larval rearing [PDF]

, 2013
Despite considerable progress in recent years, many questions regarding fish larval nutrition remain largely unanswered, and several research avenues remain open.

A Formalin‐Inactivated Vaccine Enhances Survival and Mitigates Horizontal Transmission of Red Sea Bream Iridovirus (RSIV) in Rock Bream (Oplegnathus fasciatus): Insights From Viability Quantitative PCR

Journal of Fish Diseases, EarlyView.
ABSTRACT Formalin‐inactivated vaccines are widely employed as a primary preventive strategy against red sea bream iridoviral disease (RSIVD), which poses a substantial economic threat to the aquaculture of rock bream (Oplegnathus fasciatus). However, conventional quantitative PCR (qPCR) cannot differentiate infectious virions from noninfectious vaccine

Fish Poxviruses on the Rise: Prospects for Aquatic Health

Journal of Fish Diseases, EarlyView.
ABSTRACT Fish poxviruses are increasingly recognised as emerging pathogens of fish and should be considered in cases of unexplained gill or skin pathology. Carp edema virus (CEV), the causative agent of koi sleepy disease in common carp and koi (Cyprinus carpio), represents the first known example.

Development of a Radioimmuniassay for Red Sea Bream Growth Hormone.

NIPPON SUISAN GAKKAISHI, 1995
A specific and sensitive radioimmunoassay (RIA) for red sea bream Pagrus major growth hormone (rsbGH) was developed using recombinant rsbGH, which was produced by gene technology. No cross reactivities were observed with human, bovine, and chum salmon GHs in this RIA system. The minimun detectable concentration of rsbGH dose was 40 pg/tube (0.4 ng/ml).
