    Abstract: Aeromonas salmonicida is a fish pathogen that has resulted in significant losses to the aquaculture industry worldwide. In the winter of 2018/2019, a serious outbreak of A. salmonicida infection of grass carp (Ctenopharyngodon idella) occurred in China. Since C. idella do not feed at low water temperatures, antibiotics cannot be delivered orally, thus the use of disinfectants is the only viable option to control the disease in the winter months. Therefore, the aim of this study was to elucidate the inhibitory effects of different disinfectants against A. salmonicida at various temperatures and pH values. The microdilution method was used to determine the minimum inhibitory concentration (MIC) of five disinfectants against A. salmonicida at different temperatures. The results showed that A. salmonicida was highly adaptable to temperatures ranging from 8 to 35 °C and pH values from 5 to 9. Moreover, based on the results, benzalkonium bromide (BB) had the strongest inhibitory effect at every temperature. Since A. salmonicida has strong environment adaptability, BB should be chosen to control the disease at low temperatures.

    Abstract: The effects of feeding enriched rotifers and Artemia nauplii on albinism in flounder (Paralichthys olivaceus) larvae raised in a large-scale artificial system were investigated. Larvae were first fed an S-type rotifer (Brachionus angularis) enriched with Nannochloropsis oculata for 11-12 days, which raised the n-3 polyunsaturated fatty acids (PUFA) content in the rotifer from 5.36% to 17.63% of the total fatty acids. Next, the larvae were fed one of three strains of Artemia enriched with microcapsule (50DE), vitamin A (9000 IU/l), and vitamin D (2000 IU/l) for 35 days, which raised the n-3 PUFA contents in the Artemia to 38.62%, 36.53%, and 33.86% of the total fatty acids, respectively. Among the larvae fed the enriched feeds, no more than 3‰ were albino, much fewer than in the control groups fed non-enriched foods (p 〈 0.01). In addition, n-3 PUFA contents in the muscles, growth and survival rates, and salinity tolerance were greater in founder fed the enriched foods. Artemia nauplii from Qixiangcuo (Tibet, China), enriched to 38.62% of total fatty acids, was superior in preventing albinism than the strains from Pikou or Yingkou (Liaoning, China).

    Abstract: A novel silver cluster ( SD/Ag48a ) co‐protected by p ‐MePhS − and CF 3 COO − ligands with an in‐situ generated unprecedented [Mo 8 O 28 ] 8− template has been synthesized under solvothermal condition. Single‐crystal X‐ray diffraction (SCXRD) and electrospray mass spectrometry (ESI‐MS) were used to determine the atom‐precise structure and solution behavior, respectively. Interestingly, the rare [Mo 8 O 28 ] 8− ion observed in the center of SD/Ag48a consists of 8 edge‐shared {MoO 6 } octahedra or can be deemed as three {Mo 4 O 4 } cubes fused together by sharing faces. The UV‐Vis spetcrum exhibits that a high‐energy (HE) wide absorption centered at ca. 365 nm, which can be assinged to intraligand (IL) π→π* transition absorption, whereas the low‐energy (LE) shoulder peak centered at ca. 500 nm can be ascribed to ligand‐to‐metal‐charge‐transfer (LMCT, S 3p→Ag 5 s) transition.

    Abstract: Nitrite in the aquatic environment is highly toxic to aquatic animals. However, the mechanism by which the mud crab responds to nitrite-induced stress remains unclear. In this study, we investigated the physiological response and molecular mechanism in the mud crab (Scylla paramamosain) exposed to the acute nitrite exposure (20 mg/L) for 24h. The results showed that nitrite exposure induced significant changes in antioxidant enzyme activity and MDA content. Severe cytological damage was observed in the hepatopancreas. After 24h exposure to nitrite, 11,638 differentially expressed genes (DEGs) were identified by transcriptome analysis. These DEGs were involved in many pathways related to oxidative stress and immune responses. Our results also found that FoxO signaling pathway, p53 signaling pathway, and NF-kB signaling pathway participated in the anti-stress defense against nitrite stress. The study provides new insight into the understanding of nitrite-induced toxicity in the mud crab.

    Abstract: This trial investigated the effects of Macleaya cordata extract (MCE) on the diversity and composition of the intestinal microbiota of European eels ( Anguilla anguilla ) cultured in cement tanks. After routine grading eels, six cement tanks with similar body size and fish weight (about 167 g/fish and 3620 kg/tank) were randomly divided into the control and MCE groups. The control group was fed a commercial diet, and the MCE group was fed the same commercial diet supplemented with 100 mg/kg MCE. There were three tanks in each group. This trial lasted for six weeks. Compared with the control group, the European eels in the MCE groups had a higher richness and diversity of intestinal microbiota. At the phylum level, European eels in the MCE group had higher relative abundances of Firmicutes and Proteobacteria and lower relative abundance of Spirochaetae and Fusobacteria compared to those of the control group. At the genus level, the European eels in the control group had higher relative abundances of Streptococcus and Legionella . In comparison, the relative abundances of Bacillus , Anaerobacillus , and Sphingomonas were higher in the intestine of the European eels of the MCE group. In conclusion, the dietary 100 mg/kg MCE supplementation might beneficially change the intestinal microbiota of European eels by increasing the relative abundance of certain probiotics and inhibiting some pathogenic bacteria.

    Abstract: Heat shock proteins (HSPs) play an important role in protecting organisms against various stressors. Heat shock protein 40 (HSP40) is a class of the heat shock protein family and performs a function as co-chaperone of HSP70. In this study, an HSP40 gene from the mud crab Scylla paramamosain (SpHSP40) was identified and characterized. The full-length cDNA of SpHSP40 was 1904 bp, containing an open reading frame (ORF) of 1191 bp, a 5´UTR of 118 bp, and a 3´UTR of 595 bp. The deduced amino acid sequence of SpHSP40 contained all four classical HSP40 family signatures. Quantitative real-time PCR analysis revealed that SpHSP40 transcript was expressed in a wide range of tissues, while strong expression was observed in the hepatopancreas. In order to understand the response of heat shock proteins induced by nitrite exposure, expression levels of HSPs (SpHSP90, SpHSP70, SpHSP60 and SpHSP40) mRNA in the hepatopancreas and gills were investigated. Results show that HSPs (SpHSP90, SpHSP70, SpHSP60 and SpHSP40) were up-regulated displaying a time-dependent pattern in response to nitrite stress. All these results indicate that HSPs play an important role in mediating environmental stress in mud crabs.

    A Review: Factors Affecting Outbreaks of Saprolegniosis on Aquatic Animals

    Abstract: In this paper, we review the current knowledge regarding factors affecting the outbreaks of saprolegniosis. Saprolegniosis is a serious disease which can cause significant economic losses in aquaculture. Oomycetes are considered to be responsible for the disease. Outbreaks of saprolegniosis occur when equilibrium between pathogenic oomycetes and host resistance is disturbed. This may be the result of an increase in numbers or virulence of the zoospores of oomycetes in the water, or an increase in the susceptibility of the host. The presence of oomycetes zoospores in the environment is regarded as one of the most important causes of saprolegniosis. However, important differences have been found between plant and animal pathogenic oomycetes and appear to be related not only to tactic responses to environment, but also to infection strategies to a host. In addition, fish are more susceptible to infection by pathogenic oomycetes when physically injured, stressed or infected. Furthermore, water environmental factors, such as temperature, salinity, and microorganisms, should be carefully considered since they play a key role in the outbreaks of saprolegniosis.

    Abstract: In this study, the growth performance and apparent digestibility coefficients (ADCs) of dry matter (DM), crude protein (CP), crude lipid (EE), gross energy (GE), phosphorus (P), essential amino acids (EAA), and nonessential amino acids (NEAA) for fish meal (local) (FM), soybean meal (SBM), rapeseed meal (RM), cottonseed meal (CM), peanut meal (PM), and extruded soybean (ESB) were determined for red swamp crayfish Procambarus clarkia, (weight 5.43 ± 0.21 g), using a reference diet (RF) and test diets (70% RF diet plus 30% of tested ingredient) containing 0.1% Yttrium oxide as an inert marker. The results showed that there was no significant difference in SGR, FCR, and survival among all groups (P 〉 0.05). Apparent digestibility of DM, CP, EE, P, and GE of six feed ingredients ranged from 62.8 to 71.4%, 71.2 to 90.3%, 44.2 to 92.1%, 70.1 to 83.9% and 40.3 to 63.5 %, respectively. From the data for the six feed ingredients, SBM was found to contain the highest ADCs levels in DM (71.4%) and GE (83.9%). FM recorded the highest ADC in EE (92.1%), while PM and CM had the highest ADCs of CP (90.3%), and P (63.5%), respectively. The lowest apparent digestibility of DM, CP, and GE was found in RM, the lowest apparent digestibility of EE was found in ESB, and FM had the lowest ADC of amino acids. Based on the current findings, SBM, CM, and PM could be considered potential substitutes for FM in diets for red swamp crayfish.

    Abstract: Pterophyllum scalare is a popular ornamental fish species, but current rearing methods result in high mortality, low fertility, disease incidence, and slow growth in aquarium conditions. Research on co-feeding for ornamental fish at the juvenile or adult stage needs to be completed. This study implemented a “snacking” feeding strategy using Artemia sp. to evaluate changes in fish survival rate, growth performance, and enzyme activity related to digestion, antioxidants, and immunity in a recirculating aquaculture system. Two feeding strategies were tested: one group was fed a commercial diet plus Artemia sp. (0.1% of diet) as “snacking,” and another group was fed only the commercial diet as normal. “Snacking” with Artemia sp. enhanced fish’s survival and growth performance, with higher relative weight rate, standard length, and total length than the control group. Specific growth rates for weight, standard length, and total length were also more significant in the supplemented group compared to the control group. The activity of amylase, superoxide dismutase, and glutathione peroxidase was substantially higher in the supplemented group. Adding Artemia sp. as a supplement under a “snacking” feeding strategy to the control diet was beneficial for P. scalare juvenile rearing and can guide managing recirculating farming activities.
