The purpose of this study was to investigate the eating habits and nutritional knowledge of elementary school students in regards to seafood in school meals. More than 80.6% of elementary school students reported an 'average' preference for seafood. While 'taste' and 'healthy food' were common reasons to prefer marine products, 'unpleasant taste and smell' was a common reason not to prefer seafood. Students in general stated 'eating if possible' as their attitude towards seafood in school meals, 38.1% responded 'eating all' as their intake level. There was a significant difference between preference for seafood by gender [boys, 3.44; girls, 3.64 (P<0.01)]. Also, students significantly difference preferred some types of seafood over others. The students who enjoyed eating seafood had more regular and balanced diets and a better attitude toward dietary life and health than did the counterparts who did not prefer seafood. A significant difference (P<0.05) in knowledge existed according to gender; girls had a higher level of knowledge than did boys.

The purpose of this research paper is to segment seafood market and find the factor and process that divide the segment market. Cluster analysis and in-depth interview was performed to identify meaningful segment market. The result of the research found three segment market such as seafood integration familiarity group, domestic seafood familiarity group, seafood unfamiliarity group. Seafood integration familiarity group is active consumer that consume both domestic and imported seafood at home. This group have high preference and familiarity about seafood. Seafood familiarity group purchase imported seafood for the reason that imported seafood is cheaper than domestic seafood and have similar quality level. Domestic seafood familiarity group consume mostly domestic seafood and not purchase imported seafood for the reason that imported seafood have low quality and safety. This group have high preference and familiarity about seafood. Seafood unfamiliarity group is low preference group about seafood and seldom eat at home. This study found that the main factor that divide segment market is seafood familiarity that formed by experiencing seafood in youth and seafood familiarity is main factor that determine consumption degree of seafood at home.

In order to analyze the distribution channel of marine products in Korea, this study shows SCM approach to redesign of the marine distribution channel with case study related to previous literatures. In view of the supply chain and the future impact of RFID on the marine SCM on the recognition of the importance of the seafood traceability system, this study also provides the possibility to accomplish effective SCM for integration of production, storage, transportation, delivery, and sale when RFID is used in the seafood distribution channel based on the expansion of awareness on the marine product traceability. The traceability system for seafood is considered as the distribution infrastructure established in RFID deployment. By introducing Lotte mart case, this case study also discusses the marine distribution structure in view of the supply chain, to present an effective foundation for supplying seafood throughout production, distribution, and consumption. This is achieved by introducing RFID in an ubiquitous environment, and suggesting far more efficient control planning throughout the seafood distribution channel in view of the expected effects resulting from the introduction. In addition, as the alternative of solving this situation, this study propose the supply chain in seafoods by comprehensive management in whole distribution channels. In the SCM in seafood perspectives, HACCP can take into account the whole seafood chain from the point of supply to the point of consumption when assessing hazards. As the contributions of this study, this study emphasizes the seafood industry first should require the establishment of the relevant infrastructure, for which the efforts of the government and demonstrative project participants are essential.

Changing concepts in fishery science increasingly are recognizing depletion of traditional stocks, utilization of alternate(non-traditional) species, demand for high quality products, and a total resource utilization approach. Innovative practices are occurring in fisheries processing wherein solid and liquid discharges are no longer treated as 'waste,' but rather as valuable feedstocks for recovery of a variety of value-added ('value enhanced') by-products. Among these are protein hydrolysates, soluble proteins and amino acids, proteolytic enzymes, flavor and flavor extracts, pigments, and biopolymers such as chitosan. Properties and applications of this deacetylated derivative of chitin are noted. Crustacean processing by-products are discussed in terms of their serving as materials for generation of natural flavors and flavor extracts, and products such as fish sauces using contemporary enzymatic techniques. Various food and feed applications of fisheries processing by-products are illustrated with increased usage seen in formulated diets for an expanding aquaculture market. Examples are given of aquaculture becoming increasingly significant in global fisheries resource projections. Critical issues in the international seafood industry Include those of seafood quality, processing quality assurance (HACCP), and recognition of the nutritional and health-related properties of fisheries products. A variety of current seafood processing research is discussed, including that of alternate fish species for surimi manufacture and formulation of value-added seafood products from crawfish and blue crab processing operations. Increasing emphasis is being placed on international aspects of global fisheries and the role of aquaculture in such considerations. Coupled with the need for the aquatic food industry to develop innovative seafood products for the 21st century is that of total resource utilization. Contemporary approaches in seafood processing recognize the need to discard the traditional concept of processing 'waste' and adapt a more realistic, and economically sound, approach of usable by-products for food and feed application. For example, in a period of declining natural fishery resources it is no longer feasible to discard fish frames following fillet removal when a significant amount of residual valuable flesh is present that can be readily recovered and properly utilized in a variety of mince-based formulated seafood products.

The purpose of this study is to understand the perception of fishery products and processed food of marine products in college students through empirical analysis. 446 questionnaires were used in the analysis. As a result of the empirical analysis, the frequency of consumption of aquatic food was 2~3 times a week, the place of intake was good for taste of home and aquatic foods, respectively. Purchase motifs of processed fish products are easy, the frequency of ingestion is 3 to 4 times a week, the criteria for selection were always consumed, and the taste was considered to be high when purchased. The perception of nutrition and necessity of consumption of aquatic foods was high and radioactivity was low. 133 male students (57.8%) and 98 female students (45.4%) were aware of the aquatic traceability system. The college students generally has a high preference for the taste of marine products and high frequency of consumption, and they recognized that nutritional excellence and necessity were positive. The marketing strategy should be developed by developing proper product considering the age level and sex of consumers. The limitation is that they are college students in Busan and Gyeongsang provinces and coastal areas.

The purpose of this study is to analyze consumer preference for fish farm HACCP certification using conjoint analysis. This study used raw flatfish product to evaluate the fish farm HACCP. In this study, 500 consumers were surveyed using panel survey and stratified sampling. In the recognition analysis, the farm HACCP certification system was found to be highly recognized by consumers. It can be seen that the brand assets accumulated by existing food and agricultural HACCP certification were transfered to the fish farm HACCP and absorbed. Consumers perceived fish farm HACCP certification as similar one with existing food and agricultural HACCP. Conjoint analysis evaluated three levels factors. The attributes and levels evaluated were : price(25,800 won, 28,400 won, 31,000 won), certification(fish farm HACCP, seafood traceability, and non certified), and origin(domestic, JEJU, and WANDO). The important levels were in order of price(40.8%), certification(30.2%) and origin(29.0%). We found that consumers give higher utility to fish farm HACCP certification compared with non certified and seafood traceability certification. Market simulation results showed that the fish farm HACCP product has 12%p higher market share than non certified products. Seafood traceability certification showed 4.6%p higher market share than non certified products.

The Faster RCNN-based shellfish recognition algorithm is introduced for shellfish recognition studies that currently do not have any deep learning-based algorithms in a practical setting. The original feature extraction module is replaced by DenseNet, which fuses multi-level feature data and optimises the NMS algorithm, network depth and merging method; overcoming the omission of shellfish overlap, multiple shellfish and insufficient light, effectively solving the problem of low shellfish classification accuracy. In the complexifier test environment, the test accuracy was improved by nearly 4%. Higher testing accuracy was achieved compared to the original testing algorithm. This provides favourable technical support for future applications of the improved Faster RCNN approach to seafood quality classification.

This study was conducted to provide the information necessary for the development of native local foods associated with the "2008 World Insect Festival in Hampyeong" and to contribute to the efforts to market the festival as tourist attraction and increase the income of the local community. To assess the local foods and restaurants, we investigated the principal products, inclination for sightseeing and recognition of the "Butterfly festival" by distributing questionnaires to local restaurant operators, employees and general tourists. The result was as follows: 1. The general tourists chose scenery as the most important factor in a sightseeing tour, followed by food, lodging, and transportation. 2. The tourists enjoyed eating native local foods, and they indicated that the taste was important. 3. Regarding the cost of food, 53.6% of the respondents answer that 10 to 20 thousand won was a resonable price, and they also reported wanting to eat seafood in Hampyeong. Thus the Menu of seafood to be served at the Hampyeong festival needs to be developed first followed by that of the healthy food. This result showed that individuals prefer fish to meat and healthy food to high-calorie foods.

In this study, we assessed consumers' recognition of frozen foods via a survey study, and monitored the contamination levels of total aerobic bacteria and Escherichia coli in imported and domestic frozen seafoods obtained from five whole sale markets in Seoul. A questionnaire used to assess the perception of frozen food safety and the attitude towards frozen food usage was developed and distributed to 350 adults. A total of 324 questionnaires were subjected to frequency analysis and a chi-square test, using SPSS for Windows. The results of our survey study demonstrated that 44.6% of the respondent consumed frozen processed foods two to three times per month, with dumplings being the most frequently purchased. 70.5% of the respondents selected "convenient cooking" as the principal reason for their frozen food purchases. 58% of the respondents believed that frozen processed food is not safe to eat as the result of food additives and changes in quality during the shelf life period. Consumers most profoundly preferred frozen seafood originating from America, and preferred that from China least profoundly (81.2%). Microbiological analyses demonstrated that the aerobic plate counts of frozen seafood, regardless of origin, fulfill the standard requirements except for one frozen clam (6.6 Log CFU/g), which was a heated-frozen domestic product. In addition, E. coli was isolated from frozen cooked mussels, frozen raw clams and squids, thus indicating that more strict hygienic regulation for frozen seafoods will be necessary to protect the consumer in both domestic and foreign markets.

Sea cucumber (Apostichopus japonicus) is a popular seafood source in Asia, including South Korea, and its consumption has recently increased with recognition of its medicinal properties. However, because raw sea cucumber contains various microbes, its ingestion can cause foodborne illness. Therefore, analysis of the microbiota in the whole body of sea cucumber can extend our understanding of foodborne illness caused by microorganisms and help to better manage products. We collected 40 sea cucumbers from four different sites in August and November, which are known as the maximum production areas in Korea. The microbiota was analyzed by an Illumina MiSeq system, and bacterial amounts were quantified by real-time PCR. The diversity and bacterial amounts in sea cucumber were higher in August than in November. Alpha-, Beta-, and Gammaproteobacteria were common dominant classes in all samples. However, the microbiota composition differed according to sampling time and site. Staphylococcus warneri and Propionibacterium acnes were commonly detected potential pathogens in August and November samples, respectively. The effect of experimental Vibrio parahaemolyticus infection on the indigenous microbiota of sea cucumber was analyzed at different temperatures, revealing clear alterations of Psychrobacter and Moraxella; thus, these shifts can be used as indicators for monitoring infection of sea cucumber. Although further studies are needed to clarify and understand the virulence and mechanisms of the identified pathogens of sea cucumber, our study provides a valuable reference for determining the potential of foodborne illness caused by sea cucumber ingestion and to develop monitoring strategies of products using microbiota information.
