The gelling and structural properties of microbial transglutaminase (MTGase) and pectin modified fish gelatin were compared to investigate their performances on altering fish gelatin properties. Our results showed that within a certain concentration, both MTGase and pectin had positive effects on the gelation point, melting point, gel strength, textural, and swelling properties of fish gelatin. Particularly, low pectin content (0.5%, w/v) could give fish gelatin gels the highest values of gel strength, melting temperature, and hardness. Meantime, flow behavior results showed that both MTGase and pectin could increase fish gelatin viscosity without changing its fluid characteristic, but the latter gave fish gelatin higher viscosity. Both MTGase and pectin could increase the lightness of fish gelatin gels but decreases its transparency. More importantly, fluorescence and UV absorbance spectra, particle size distribution, and confocal microscopy results indicated that MTGase and pectin could change the structure of fish gelatin with the formation of large aggregates. Compared with MTGae modified fish gelatin, pectin could endow fish gelatin had similar gel strength, thermal and textural properties to pig skin gelatin.

The ecological health of aquaculture water is threatened by wasted fish feed and herbicides. In order to study the effect of prometryn and fish feed on Microcystis aeruginosa growth based on Monod and Logistic functions, four different concentrations of prometryn (0, 50, 100 and 200 μg L −1 ) and two different dosages of fish feed (0.075 g, 0.15 g; d < 0.85 mm) were added into the culture medium, and the fish feed was the source of nitrogen and phosphorus in the MII medium. Results showed that Microcystis aeruginosa growth can be fitted well by Logistic and modified Logistic functions with 0–200 μg L −1 prometryn ( R 2 = 0.981–0.998 and R 2 = 0.989–0.999, respectively). With the same concentration of prometryn, the maximum algae density ( N max ) of Microcystis aeruginosa calculated by both Logistic and modified Logistic functions increased with increasing dosage of fish feed and with the same dosage of fish feed, N max declined with increasing concentrations of prometryn. Inhibition of prometryn on algae growth stimulated by fish feed is of double concentration-dependence, inhibition rates ( I ) are lower in 0.15 g fish feed medium than 0.75 g ones generally, implying that more nutrients can alleviate the stress caused by prometryn on algae. Derived formula for the specific growth rate, growth rate and inhibition rate using modified Logistic function agreed reasonably well with measured data. Jointly application of modified Monod and Logistic functions can better describe the relationship between specific growth rates and nutrients concentrations compared to combination of Monod and Logistic functions. In addition, equations for describing variations of nutrients concentrations (PO 4 3- -P and NH 4 + -N) with time were also derived based on both modified Monod and Logistic functions, which agree reasonably well with the measured data. In sum, the combination of modified Monod and Logistic functions provides a promising and robust method in studying algal growth stimulated by fish feed in incubator experiments.

A novel procedure for selective extraction of malachite green (MG) from fish samples was set up by using magnetic molecularly imprinted polymers (MMIP) as the solid phase extraction material followed by electrochemiluminescence (ECL) determination. MMIP was prepared by using Fe 3 O 4 magnetite as magnetic component, MG as template molecule, methacrylic acid (MAA) as functional monomer and ethylene glycol dimethacrylate (EGDMA) as crosslinking agent. MMIP was characterized by SEM, TEM, FT-IR, VSM and XRD. Leucomalachite green (LMG) was oxidized in situ to MG by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). And then MMIP was successfully used to selectively enrich MG from fish samples. Adsorbed MG was desorbed and determined by ECL. Under the optimal conditions, calibration curve was good linear in the range of 0.29–290 μg/kg and the limit of detection (LOD) was 7.3 ng/kg ( S / N =3). The recoveries of MMIP extraction were 77.1–101.2%. In addition, MMIP could be regenerated. To the best of our knowledge, MMIP coupling with ECL quenching of Ru(bpy) 3 2+ /TPA for the determination of MG has not yet been developed.

Fish intestines and livers are usually considered as delicious and nutritious food in China. Acidic polysaccharides are important nutrients in these food of animal origin, but there is currently little information regarding their quantitative distributions. The present study demonstrated a method to quantify acidic polysaccharides simultaneously by analyzing their disaccharides produced from the acid hydrolysis using high-performance liquid chromatography (HPLC) coupled with triple quadrupole mass spectrometry. The recoveries for these acidic polysaccharides were all 97%–115% with relative standard deviation of 3.0%–9.0%. All of the acidic polysaccharides had good linearities. Then this method was applied to determine the composition of acidic polysaccharides in 5 edible fish livers and intestines. Besides well-known glycosaminoglycans (GAGs) including hyaluronic acid (HA), Chondroitin sulfate (CS), dermatan sulfate (DS) and heparin (HP), 4 novel acidic polysaccharides including 2 GAGs and 2 non-GAGs comprised of hexose-hexuronic acid repeating units were also found. CS and HP were the major acidic polysaccharides components in fish intestines and livers, respectively. The absolute amounts of acidic polysaccharides differed greatly in these fish tissues, but their proportions showed similarity in the same type of tissues. The present study demonstrated an effective method for acidic polysaccharides quantification, and revealed acidic polysaccharides compositions of edible fish livers and intestines.

In the present study, a new adsorbent based on carboxylated cellulose nanocrystal (CCN) was developed for the adsorption of Pb(II) from fish sauce. The prepared adsorbent material was characterized by zeta potential, FT-IR, XRD, and XPS tools. The changes in the morphological structure of the developed CCN surface were evidenced by SEM and TEM. The favorable adsorption conditions were selected by studying the contact time, initial concentration, temperature, and concentration of the used glutamic acid and NaCl. The results indicated that the Langmuir isotherm model agrees very well with experimental adsorption data ( R 2 = 0.9962) with a maximum adsorption capacity 232.56 mg/g of Pb(II) at 293.2 K. Additionally, data of the adsorption kinetics follow the pseudo-second-order kinetics ( R 2 > 0.9990). On the other hand, the thermodynamics studies show that the adsorption process is spontaneous and endothermic. Furthermore, the developed CCN could be regenerated using acid treatment with a good reusability for Pb(II) adsorption. The results clearly indicated that the synthesized CCN could be effectively applied as a new material for Pb(II) adsorption from fish sauce solutions.

Wastewater treatment plants (WWTPs) can be important point sources for the discharge of engineered nanomaterials to natural surface waters. In this study, we investigated the fate of nano-TiO 2 in two full scale WWTPs and their receiving streams in northern China (i.e., the Binhe and Minxin rivers, which flow to the Xiaohe River). High resolution transmission electron microscopy , energy dispersion X-ray spectroscopy and X-ray photoelectron spectroscopy analyses indicated that Ti in colloids present in the WWTP effluents and receiving streams originated mainly from engineered nano-TiO 2 . Most of the nano-TiO 2 (74–85%) in the influent sewage was removed by the activated sludge , but significant concentrations (27–43 μg/L Ti) remained associated with colloids in the effluents. Surprisingly, the total concentration of Ti in the receiving river streams was higher (52–86 μg/L), indicating the importance of other sources such as urban runoff. These relatively high Ti concentrations are unlikely to originate from natural sources since they are significantly higher than those in the nearby Yuqiao Reservoir (< 5 μg/L), representing regional background levels. Consistently, Ti levels in fish collected from the Xiaohe River (including muscle and other tissues) were significantly higher than those of fish from the reservoir. Overall, TiO 2 releases through WWTP effluents and other sources (including runoff) are contributing to the relatively high observed concentrations of suspended Ti in the Xiaohe River, which results in accumulation in edible fish tissue.

A number of viral diseases have significantly impeded the growth of the aquaculture industry. Antiviral drugs represent an effective means of controlling infection. However, the efficacy of the entire therapeutic process is contingent upon the availability of an efficient delivery system. This study selected three common antiviral drugs and constructed corresponding drug delivery systems utilising single-walled carbon nanotubes (SWCNTs) as carriers. The reliability of carbon nanotubes as delivery carriers was evaluated by detecting the therapeutic effect on infectious splenic and renal necrosis virus (ISKNV). The findings demonstrated that SWCNTs can effectively enhance the absorption of the three drugs into the body, prolong their metabolic half-life, and improve the survival rate of fish infected with ISKNV. The Ribavirin-SWCNTs (RBV-SWCNTs) group exhibited the most pronounced protective effect, with a mortality rate of less than 25%. It was observed that SWCNTs facilitated the rapid transportation of ribavirin, with the drug content in the RBV-SWCNTs group being approximately double that of the free ribavirin group. Furthermore, this system markedly diminished the viral load, augmented enzyme activities, and elevated antiviral gene expression. This study indicated that carbon nanotubes are optimal carriers for antiviral drugs, which have considerable potential as a delivery vehicle for antiviral drugs to prevent viral infections in aquaculture.

A boiled fish simulation system was constructed to explore the deodorization effect of main aroma compounds (MAC) on myofibrillar protein (MP) with main fishy compounds (MFC) during heating. The results showed that the MFC content of boiled fish was reduced by 63.10–78.10 % when boiled by heat-stable emulsions loading MAC. Specifically, adding linalool, anethole, and myrcene significantly elevated the free percentage of hexanal, heptanal, and 1-octen-3-ol after heating, while the free percentage of octanal and nonanal markedly increased by adding anethole and limonene. Molecular docking exhibited that MAC and MFC possessed co-binding sites with myosin. Linalool and anethole were competitively bound to MP through hydrophobic and hydrogen bonding sites, while myrcene and limonene were via hydrophobic interaction sites. Moreover, MAC-MP formed a relatively stable structure, exhibiting increased α-helix content and decreased surface hydrophobicity, which reduced the available sites for MFC binding, ultimately desorbed MFC (65.46 %–95.89 %).

A composite zein nanofibrous mat containing fish oil and ferulic acid was successfully fabricated by electrospinning. The process became more fluent and continuous by adding 30 g/L glycerol into the polymer solutions and using modified coaxial electrospinning. The average diameter of nanofibers was 440 nm. The loading capacity and encapsulation efficiency of fish oil were 20% and 94%, respectively. FTIR data demonstrated that fish oil and ferulic acid were successfully embedded into the nanofibers and there were interactions among the molecules of zein, fish oil and ferulic acid. Addition of ferulic acid into the nanofibers significantly improved the oxidative stability of encapsulated fish oil; moreover, it did not change the release behavior of fish oil. The release of encapsulated fish oil was controlled by a combination of diffusion and macromolecular chain relaxation. This composite nanofibrous mat with favorable oxidation stability and release property is potential in application as nutrition additive.

Triethylamine (TEA) is an organic amine released by fish products during spoilage, and the concentration of TEA can be detected by sensors to determine the freshness of fish. However, current TEA sensors face issues such as low response, high detection limits, and high power consumption. In this paper, pure phase molybdenum trioxide nanosheets (MoO 3 Ns) with high-performance TEA detection were prepared by hydrothermal method. By adjusting the calcination temperatures, the sensor response was enhanced, and both the detection limit and power consumption were reduced due to chemical sensitization and reasonable interactions between the material surface and the target gas. Material characterization indicates that MoO 3 calcined at 400°C exhibits a lamellar morphology, high catalytic activity, and a crystal surface with abundant hydroxyl groups, adsorbed oxygen, and Mo 6+ . By adjusting different calcination temperatures, the response was improved and the detection limit and power consumption were reduced based on chemical sensitization and reasonable interaction between the material surface and the target gas. Material characterization indicates that MoO 3 calcined at 400°C exhibits a lamellar morphology, high catalytic activity crystal surface with abundant hydroxyl groups, adsorbed oxygen, and Mo 6+ , and has suitable specific surface area with wide pore size distribution. Gas sensitivity tests reveal that the MoO 3 -400 based sensor demonstrates excellent performance, including a high response (280/50 ppm), low detection limit (1 ppm), and low power consumption (235°C). Furthermore, the sensor exhibits outstanding cycling, long-term stability, and selectivity. Finally, the sensor's applicability was demonstrated by measuring TEA released by crucian carp to evaluate fish freshness. This paper introduces a novel method for rapidly assessing fish spoilage, providing a significant contribution to food safety.

Peroxymonosulfate (PMS)-based Fenton-like oxidation has gained attention as a promising technology for wastewater remediation. However, its widespread application is constrained by the lack of high-performance and durable activators. In this study, a magnetic graphite-like porous carbon (MGPC) derived from fish scale residues was synthesized and demonstrated exceptional PMS activation performance, effectively degrading various persistent contaminants with minimal iron leaching (<0.8 mg L⁻ 1 ). Notably, MGPC achieved high degradation rates for sulfamethoxazole (0.13 min⁻ 1 g⁻ 1 L), methylene blue (0.65 min⁻ 1 g⁻ 1 L), tetracycline (0.19 min⁻ 1 g⁻ 1 L), and rhodamine B (1.07 min⁻ 1 g⁻ 1 L), outperforming many state-of-the-art activators. This enhanced activity is attributed to the synergistic effects of multiple active components, including Fe 3 C, Fe 3 O 4 , and a nitrogen-doped carbon matrix. Additionally, the MGPC/PMS system exhibited strong resistance to interference from background constituents and maintained broad pH adaptability (3–9). Impressively, over 95 % of methylene blue was degraded after five consecutive cycles. The MGPC powders were easily recovered using an external magnetic field, eliminating the need for complex separation processes. Radical quenching experiments, in-situ electron paramagnetic resonance (EPR) analysis, and chronoamperometry confirmed that the MGPC/PMS system operates through two non-radical pathways: 1 O 2 -mediated oxidation and direct electron transfer. This innovative approach to designing efficient PMS activators from environmental waste offers a sustainable strategy for environmental pollution control.

Histamine is a naturally occurring alkaloid that is an important indicator of meat spoilage, and excessive levels in food can lead to food poisoning or trigger allergic reactions. Therefore, accurate detection of histamine in meat is crucial for evaluating freshness and ensuring meat quality. In this study, a fluorescence probe based on ionic covalent organic networks confined with molecularly imprinted polymers (iCON@MIPs) was developed for detecting histamine in aquatic products. The probe was utilized iCOFs as the light-emitting element to improve the selectivity of the system for histamine by ion attraction reaction, and its anti-interference ability enhanced through molecular imprinting technology. The maximum emission wavelength of iCON@MIPs was at 570 nm, giving it a bright yellow emission and endowing it with the ability for on-site detection. The detection limit of iCON@MIPs for histamine was 0.516 µg L − 1 , with a good recovery rate of 87.29-102.26% in fish samples. The fluorescence probe developed in this study provides an effective and rapid detection method for harmful substances in food, agriculture, environment and even medicine.
