China has been the largest producer of fish in the world since 1989 and became the largest consumer of fish and fishery products recently. With increase in China’s demand and preference for shellfishes and value-added fish products, India sees China as the second largest export destination after the US. This study analyzed the status, export performance and competitiveness of Indian fish export to China based on data (2000-2018) from trademap.org and UNCOMTRADE statistical database. Compound Growth Rate (CGR) revealed that the seafood export grew at an annual rate of 9.68% in terms of value with instability of 0.24 from 2000-2018. The Simpson Index of Diversity (SID) to the China revealed that the index values remained highest all throughout the years as compared to USA and the rest of the world. The Unit Value Realization (UVR) was found highest in live fishes ($34.92/kg) followed by fresh chilled fish ($7.19/kg), crustaceans ($5.97/kg) and others for 2018. Commodity wise RCA revealed that it is highly positive for frozen fillet meat mince (10.22) followed by crustaceans (8.0) and frozen fish (5.05), indicating that India has a strong comparative advantage in exporting these commodities to China.

Although tilapia is one of the most cultivated fish species in Bangladesh owing to its high growth rate, comparatively easy culture practices, higher survival rate and short culture period but low market preference marked it as a low-priced fish. Various approaches have been adopted to enhance consumer acceptability and ensure better use of tilapia, including the production of value-added products such as tilapia-prepared fillets, which attract increasing interest. Therefore, the current study was designed and carried out in order to prepare tilapia fillets and to estimate their shelf life at frozen (-18±20C) and refrigerated (4±10C) temperatures. Fillets were produced from tilapia collected from local fish markets of Sylhet city, Bangladesh with according to Good Manufacturing Practices (GMP) established by International Standards Organization (ISO) and packed in polyethylene bags. Proximate composition, total volatile base nitrogen (TVBN), peroxide value (PV), pH, total plate count (TPC) and sensory properties of fillets were analyzed to determine shelf-life. A portion of the fresh fillet sample was immediately analyzed and the remaining portions were preserved for up to 12 and 90 days at refrigerated and frozen storage temperatures, respectively. Results revealed that, at a definite interval of time, changes in the chemical, microbial and sensory attributes of tilapia fillets were found to be more pronounced in refrigerated storage conditions than fillets stored in frozen conditions. The shelf life of refrigerated and frozen tilapia fillet samples was 9 and at least 90 days, respectively, per the results of sensory, microbial and chemical evaluation. Res. Agric., Livest.

Abstract Tuna is a large pelagic fish that is widely found in Indonesian waters as one of the countries that have an important role in global tuna production. Moreover, tuna has the potential to be processed into frozen tuna. The added value as the result of the freezing process will increase the economic value of this product. Thus, it makes frozen tuna potential to be developed into an industry. One of the things that need to be considered in the establishment of an industry is location determination. The study was aimed to determine an alternative location for the frozen tuna industry in Banda Aceh city will be done. The method used in this research is the Analytical Hierarchy Process (AHP). The criteria used are Tuna Fish Production, Human Resources, Transportation Access, Institutional Support, and Availability of Infrastructure. The alternative location that will be determined is Kuta Alam Sub-district, Kuta Raja Sub-district, Meuraxa Sub-district, and Syiah Kuala Sub-district. The calculation result using the AHP method indicates that that the most appropriate location for the establishment of the frozen tuna industry is Kuta Alam Sub-districts with a weight of 0.428, thus the district was chosen as the best location for the establishment of the frozen tuna industry.

This research analyzes the economic indicators of the fishery complex of the Kaliningrad region in recent years. The introduction of modern biotechnological solutions in the fish processing sector is substantiated. At present, the industry focuses on oceanic and coastal fishing, large fish complexes are leading in fish processing. Food product groups are mainly represented by chilled and frozen semi-finished products. Among food fish products, the production of sterilized canned food predominates; in smaller quantities, preserves, salted, smoked, dried and dried fish products are produced. The fish factories practically do not process fish by-products and there is no production of fish meal. To improve the economic performance of the industry, it is promising to use innovative biotechnologies and advanced foreign experience, which allow processing the extracted raw materials with maximum added value. The Strategy for the Development of the Fisheries Industry of the Russian Federation until 2030, adopted in November 2019, outlines the prospects for the development of marine biotechnology in key segments - aquaculture, production of functional and biologically active products, processing of by-products. The article presents the volumes and problems of fish by-products processing accumulating at fish processing enterprises of the region. A complex scheme of biotechnological by-products processing with the production of valuable biologically active substances (proteins, lipids, mineral substances) is proposed. The technology and production line for the production of protein, protein-mineral and lipid preparations from secondary fish raw materials are described. A modular implementation of biotechnology in marine conditions is proposed. The economic calculation from the introduction of innovative biotechnology in the processing of secondary fat-containing fish raw materials is presented.

The study addresses the problems of the Fisheries industry development in the Murmansk region. It has been acknowledged that the percentage of the frozen fish in the output of hydrobionts food products is about 90 %. The focus areas for the Russian Fisheries industry are the increasing share of products with high added value and the development of the domestic consumer market of fishery products. It has been found that the air-dried and dried fish products with defined organoleptic properties is traditionally in strong demand with the population. However, the range of air-dried and dried fish products available for the consumers is rather limited. Moreover, there is a very small part of air-dried and dried fish in the total volume of hydrobionts food products. It is possible to increase the efficiency of air-dried and dried fish production by using the scientific-based process solutions, which allow to reduce the production costs and improve the consumer properties of the finished products. This paper presents the aspects of generalization of the dehydration processes in the production of dried, air-dried and smoked fish. A link between the initial, critical moisture content of fish and the potential conductivity of mass transfer coefficients has been established. A mathematical relation for calculating the duration and modeling the kinetics of drying processes in production of dried and air-dried fish has been determined. The equations for calculating the water diffusion coefficients in the critical points of the kinetics curve have been obtained. The combined use of the received patterns allows to model the dehydration processes when producing the air-dried and dried fish products, calculate the drying time, determine the moisture diffusion coefficients and build dependencies of water distribution in the thickness of the processed object.

Trout was introduced in our country in 1928 and managed to adapt to the freshwater ecosystems of the Peruvian highlands. It currently represents the economic livelihood of many micro and small-scale fish farmers, together with medium and large companies in regions such as Puno, Pasco, Huancavelica and Junín, whose growth in recent years has been considerable. The 71.98% of this resource was destined for consumption in its fresh state and only 28.02% was processed as frozen, which shows the lack of diversification of value-added products in the production chain of this sweet aquaculture species, together with a shortage of research. Therefore, the purpose of this research was to compile the latest studies, carried out in different countries, related to the processing of this species because it is an excellent raw material due to its nutritional value and techno-functional characteristics. The research work collected covered the use of traditional methods and technologies such as marinating, salting, drying, and smoking, as well as innovative restructuring processes applied to trout minced muscle and filleting by-products. These investigations found that the different food products were differentiated by their physical and sensory attributes, techno-functional properties, shelf life and/or preparation. With this review, we hope to contribute to the triple helix model focused on this resource, from and for the Andes, to promote its sustained production, productive chain, and food security for the inhabitants of the Andean regions.

Abstract Background Diagnosis and treatment of hematological malignancies relies increasingly on the detection of underlying genetic abnormalities. Various laboratory techniques, including karyotyping, SNP-array, FISH, MLPA and RT-PCR are typically required to detect the full spectrum of clinically relevant genetic aberrations. These techniques are also hampered in their sensitivity by their targeted approach or lack of resolution. Ideally, an unbiased genome wide approach like RNA sequencing (RNA-seq) as a one-test-fits-all, could save costs and efforts and streamline diagnostic procedures. In the Netherlands, the care for all children with oncological disorders has been concentrated in a single, national center. Within the Laboratory of Childhood Cancer Pathology, we aim for a comprehensive diagnostic pipeline by implementing RNA-seq to aid diagnosis, prognosis and treatment of all children with cancer in the Netherlands. Methods We have established an RNA-seq based diagnostic pipeline, primarily aimed at detecting gene fusion events. Library prep is performed on 50-300 ng total RNA isolated from fresh (frozen) samples, followed by ribo-depletion and subsequent paired-end sequencing (2x150 nt) using the Illumina NovaSeq platform. Data is analyzed using the StarFusion algorithm for gene-fusion detection. We are prospectively comparing the results with routine diagnostic procedures. In addition, we are validating the detection of single nucleotide variants (SNVs) from RNA-seq data and developing a diagnostic classifier, using a nearest neighbor network approach. Results Based on RNA-seq profiling in diagnostics for all patients entering the Princess Maxima Center, there are several use-cases that highlight the value of RNA-seq. 1) In a prospective cohort of 244 patients (pan-cancer, including 97 hematological malignancies) we have shown that the diagnostic yield for detecting gene fusion events increased by approximately 40% compared to classical methods. An example is the TNIP1--PDGFRB gene fusion in a patient with pre B-ALL, making this patient eligible for imatinib treatment, which was not detected by other methods. 2) Variant calling on RNA-seq shows that activating mutations in e.g. KRAS are detected with high sensitivity, stratifying patients for therapeutic MEK intervention. 3) By expression outlier analysis, we were able to detect various promotor exchanges, e.g. IGH-MYC or IGH--DUX4, which are typically hard to detect by molecular techniques since the genomic breakpoint is highly variable and no chimeric transcript is formed. 4) Preliminary results from our diagnostic classifier show its potential to predict subclasses of hematological malignancies, e.g. high-hyperdiploid or bi-phenotypic ALL patients. 5) Fusion gene breakpoints detected by RNA-seq serve as a target for MRD analysis, allowing us to monitor disease progression and therapy response in individual patients. Currently, RNA-seq data is available for more than 1500 pediatric tumor samples. At the upcoming conference we will present an update of our results and some typical cases highlighting the added value of RNA-seq in routine diagnostics. Conclusion We show that RNA-seq on pediatric cancer samples is feasible and of great value for routine diagnostics. It has a higher sensitivity to detect gene fusion events compared to targeted assays. RNA-seq based gene fusion detection, in combination with mutation and expression analysis, is also promising to improve classification of malignancies, prognosis and stratification of patients for targeted therapies.

Abstract Background: Defects in the p53 gene predispose B-CLL patients for an inferior outcome, particularly a resistance to treatment by conventional chemotherapeutics. Very little data exist, however, about the efficacy of monoclonal antibody rituximab on B-CLL cells bearing p53 abnormalities. One reason for that might be a methodological - rituximab alone does not have virtually any effect on the viability of B-CLL cells when cultivated in vitro, unless an active human plasma is added. After that, however, the cells are quickly lysed by complement, what is a process independent on p53. Aims: We used an in vitro system (not containing the active human plasma) to monitor a rituximab activity on B-CLL cells with p53 inactivation in relation to subsequently used nucleoside analog fludarabine, which demonstrably acts through the p53 in B-CLL cells. Methods: The p53 abnormalities in blood samples of B-CLL patients were detected by FISH and by functional yeast analysis coupled to sequencing, as described previously (Trbusek et al., Leukemia2006, 20: 1159–1161). Vitally frozen samples were used in all cases, after 24h pre-cultivation. Mononuclear cells were cultivated for 72h with or without 20μg/ml of rituximab and subsequently for another 48h with four different concentrations of fludarabine (40μg/ml–0,625μg/ml). The cell viability was determined by a WST-1 assay. A sensitization effect of rituximab pretreatment was determined by an ANOVA analysis, with the value p=0,05 being a threshold for a statistical significance. To monitor an apoptosis (a suppossed mechanism of fludarabine action), the Western blotting was used for the caspase-3 cleavage, which was proved previously to occur in drug-treated B-CLL cells. Results: In the subgroup of eleven p53-wt samples the three cases manifested sensitization by rituximab for fludarabine activity, one case showed an oposite (antagonistic) effect, while there was no significant difference for another seven samples. Among ten p53-mutated samples there was just one case exhibiting no influence of rituximab pretreatment (with the p53 alleles being deletion / 281 Asp→Glu), one sample manifested with antagonistic effect (del / 220 Tyr→Cys), while the remaining eight cases showed a statistically significant sensitization by rituximab (del / truncated protein aa 314, del / no protein, del/ wt protein, del / 248 Arg→Gln, del / 249 Arg→Gly, del / del aa 252, del / del aa 252–254, and a composed mutant 281Asp→Asn / 254 Ile→Thr). We noticed a statistically significant potentiation also in three out of four ATM-deleted samples (ATM is the p53-regulatory kinase). An apoptosis occured after fludarabine addition both in pretreated and control cells, as evidenced by the caspase-3 cleavage in some (but not all) samples. Conclusions: We show, to our konwledge for the first time, that rituximab can significantly sensitize the B-CLL cells bearing different types of p53 mutations to fludarabine. This result warrants further investigation of the mechanism behind.

Pacific whiting (Merluccius productus) is the most abundant groundfish species off the California, Oregon and Washington Coasts. The fish are mainly used as a raw material for the production of surimi. However, it is not economically wise to depend only on one product. There is a need to diversify the industry and develop a portfolio of product forms able to compete on the global marketplace. This study examines the characteristics of Pacific whiting individually quick frozen (IQF) fillets through an evaluation of consumer acceptability and sensory analysis, as well as their correlations to biochemical and physical properties. Additionally, a comparison is made between Pacific whiting IQF fillets and characteristics from seven other fish species. Sensory analysis by a trained panel showed Pacific whiting scoring highest in the flavor category of shellfish, medium in overall flavor intensity and fresh fish flavor, and high in moistness. Two different cooking methods: microwave (rapid) and conventional oven (slow) were studied with the results showing that the rapid method improved a number of texture attributes. Correlations between sensory texture attributes and instrumental texture results of Pacific whiting and the protease activity were found for both cooking methods but much higher in the slow one. All eight species were tested in a consumer test using a nine-point Hedonic scale. There were no significance differences (p>0.05) in flavor, texture, and overall acceptance of Pacific whiting with most of other commercial fish. However, the amount of variation in each group was high. No significant differences were found in firmness of Pacific whiting when compared to Dover sole. Five-point purchase intent scale showed no differences in consumers' willingness-to-buy when compared to species presently available in the marketplace. Pacific whiting IQF fillets, kept in frozen storage for 12 months, showed no differences in the flavor and texture attributes with fillets frozen for one month. The following findings are based on the information gained from the focus group: (1) The most important factor affecting consumers' purchasing decision on fish is flavor, (2) Fish flavor must be fresh, mild, pleasant, and true to species, and (3) Fish texture is varied. Texture is not as important as such factors as flavor, odor, appearance, and thickness of fillets. Pacific whiting was found to be tasty and acceptable to the focus group participants. Qualitative and quantitative data collected from the focus group and the consumer tests, combined with its sensory characteristics' similarity to desirable commercial fish suggest a good potential of Pacific whiting in being utilized as IQF fillets.
