In vitro metabolism of steroid hormones by ovary and hepatopancreas of the crustacean Penaeid shrimp Marsupenaeus japonicus

Scientia Marina, 2003
Radioimmunoassay (RIA) was applied to identify selected metabolites obtained in in vitro incubations of ovarian and hepatopancreatic tissues from female Marsupenaeus japonicus in previtellogenic and vitellogenic maturation stages.

Purification and Specificity of a Deoxyribonuclease of the Hepatopancreas of Octopus vulgaris

Journal of Biological Chemistry, 1966
Abstract A magnesium-dependent deoxyribonuclease (deoxyribonucleate oligonucleotidohydrolase), acting optimally at pH 8.5, has been purified 400-fold with respect to protein from the hepatopancreas of Octopus vulgaris. According to Laskowski's scheme of classification of nucleolytic enzymes (16), the purified enzyme is: (a) specific toward the sugar ...

Investigating the Effect of Microcystins on the Transcriptomics of Hepatopancreas in Penaeus vannamei Using Reverse-Gavage

Progress in Fishery Sciences
Whiteleg shrimp (Penaeus vannamei) significantly contributes to the Chinese aquatic product market. However, continuous intensification has led to eutrophication in water bodies, resulting in frequent cyanobacterial blooms.

Insight of vitellogenesis patterns: A comparative analysis of the differences between the primary and secondary vitellogenesis period in the ovary, hepatopancreas, and muscle of mud crab, scylla paramamosain

Frontiers in Genetics, 2022
The mud crab, Scylla paramamosain, has abundant nutrients in its edible parts, ovary, hepatopancreas, and muscle during the ovarian maturation stage. The ovary of S. paramamosain can re-mature after spawning during the secondary ovarian maturation period.

Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

Animal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.

The Role of Dietary Fatty Acids in Modulating Blue Crab (Callinectes sapidus) Physiology, Reproduction, and Quality Traits in Captivity

Animals
The invasive blue crab is challenging the Mediterranean basin, progressively declining local populations. This reflects a lower prey availability and suitability of dietary nutrients (mainly n-3 polyunsaturated fatty acids, PUFA). The present study aimed

Integrated analysis of mRNA and microRNA expression profiles in hepatopancreas of Litopenaeus vannamei under acute exposure to MC-LR

Frontiers in Genetics, 2023
Intensive shrimp farming is often threatened by microcystins Hepatopancreas is the primary target organ of MCs in shrimp. To investigate the response of hepatopancreas to acute MC-LR exposure, the expression profiles of RNA-seq and miRNA-seq in the ...

Epidemiological Survey and Genomic Insights Into Ostreid Herpesvirus 1 Transmission in the Blood Clam Anadara broughtonii in China (2019–2025)

Animal Research and One Health, EarlyView.
Seven‐year surveillance reveals a cold‐adapted OsHV‐1 lineage in blood clams, with disease onset at 13°C—3–5°C lower than in oysters—and identifies asymptomatic carriers and facility effluent as key transmission routes. ABSTRACT Ostreid herpesvirus 1 (OsHV‐1) poses a major threat to bivalve aquaculture, but its impact on blood clams (Anadara ...
