Cu accumulation and depuration in various tissues of the crayfish Astacus leptodactylus was investigated. Adult specimens were exposed to 0.5, 2.5 and 5.0 mg Cu/L under static conditions for three weeks. At the end of the 3rd week the specimens were divided into three groups and left in dechlorinated water for either 1, 2 or 3 weeks for depuration. After 7, 14 and 21 days, four crayfish from ea...

HIGHLIGHTS EsCPR was isolated from E. sinensis using RT-PCR and RACE methods. mRNA markedly expressed in the hepatopancreas stomach of sinensis. The results showed a higher CPR expression level premolt than other stages.

The sublethal stress of the organophosphate insecticide chlorpyrifos was investigated in different tissues of the freshwater crab (Barytelphusa guerini). Crabs were exposed to 1/3 of LC50 concentrations for 7, 14, 21, and 28 days. After 28 days, they were released into fresh water and kept for 18 days for recovery. The study was conducted by estimating total proteins, amino acids, ammonia, urea...

Highlight Research Cinnamaldehyde for shrimp Dynamics of Vibrio and the correlation with health status Green yellow bacteria in water, intestine, hepatopancreas decrease number green Abstract Disease can cause mortality high economic losses caused by Vibriosis group. One alternative is using cinnamaldehyde which function as an anti-microbial inhibit production toxins released microorganisms. Th...

This research evaluated the protective effect of vitamin A (VA) on adverse fish oil (FO) substitution with palm (PO) in an economical crab Eriocheir sinensis. Three diets FO, PO, and PO + 8000 IU / kg VA as main lipid sources were fed to crab...

Background: Histological studies in organs like hepatopancreas and gill of the freshwater fish, Cyprinus carpio, were made to assess tissue damage due to sub-lethal concentration of cadmium after a long exposure period. Methods: This study was conducted in University of Tehran, in 2013. The fish were divided into two groups in 1000 litre fiberglass tanks supplied with dechlorinated water [hard...

To further investigate the immune response of Macrobrachium rosenbergii against Aeromonas veronii, comparative transcriptomic analyses M. hepatopancreas were conducted on challenge and control groups at 6, 12, 24 h post-infection (hpi), independently. A total 51,707 high-quality unigenes collected from RNA-seq data, 8060 differentially expressed genes (DEGs) discovered through paired comparison...

Abstract To explore energy utilization during molting stage, matured and juvenile red claw crayfish were selected to determine changes in lipid composition fatty acid contents of hepatopancreas. Moreover, the expression binding protein (FABP) gene was determined verify acids at molecular level. Results showed that after molting, crude content significantly lower than before ( p <.05). Among ...
