The objective of this study is to suggest the improvement method of the profitability in our marine fish culture business. So I investigated the actual condition for aquaculture farms in South Sea coast by the question and actual survey. 1 recognized the following facts; 1) The marine floating netcage system are a great portion in two province - Kyeongnam and Cheunnam, 2) The rockfish are reared absolutely much more than the olive flounder, 3) The polyculture by various species are more carried out than the monoculture of the olive flounder or rockfish, etc. I analyzed the profitability in olive flounder monoculture, rockfish monoculture, olive flounder and rockfish polyculture, and rockfish polyculture taking turns year by year respectively. At a result I comfirmed that the net income to net sales was the highest in the olive flounder monoculture bacouse the olive flounder,s sale price was higher than rockfish price. But internal rate of return(IRR) and net present value(NPV) were high in the olive flounder and rockfish polyculture or the rockfish taking turns polyculture. The reasons were alttributed to their high utility of a netcage and to reduction of a capital cost. So, I suggest 1) to feed the bigger product in short term, 2) to reduction of a feed and seed cost, 3) to increase a survival rate of fish and 4) to enlarge production by highly utilizing a netcage. And I recognized that a aquaculture manager should make constantly an effort to gain more profit by rearing more good products and by reducing a production cost.

Microbiological and organoleptic qualities of boiled anchovies were evaluated during storage for 8 months at different temperatures and packaging methods. Microbial populations of marketing samples were 106~107 CFU/g in aerobic bacteria, 103~106 CFU/g in yeasts/molds and 103~105 CFU/g in coliforms, respectively, which were the highest in retail sample, followed by in military goods and wholesale sample. Moreover, anchovies supplied for retail sale and military goods were contaminated with sanitary indicative microbes. The samples stored at ambient condition(15~33$^{\circ}C$, RH 5$0^{\circ}C$95%) lost their marketable quaity mainly due to microbial propagation prior to 6 months, irrespective of packaging methods, corrugated-cardboard box and laminated-film(nylon 15${\mu}{\textrm}{m}$/PE 100${\mu}{\textrm}{m}$). However, cooling(5~1$0^{\circ}C$) as well as well as freezing temperatures($\leq$-18$^{\circ}C$) following laminated-film packaging were effective for keeping the organoleptic qualities of stored anchovies up to 8 months. The population of yeasts and molds was shown the quality-indicative criteria for stored anchovies and their critical levels were 5.00 log counts/g, showing a higher negative-correlationship(r=-0.901) with changes in organoleptic quality.

This research investigates the relationship among product quality, service quality, perceived value, customer satisfaction, and behavior intentions. Validated measurements were identified from a literature review. The measurement model and the conceptual model depicting hypothesized relationships were evaluated based on responses from 220 customers using confirmatory factor analysis and structural equation modeling. The testing results show that, for the direct path, product quality has a significant, positive influence on customer satisfaction, and behavioral intentions. Also, perceived value directly influences customer satisfaction and behavioral intentions and satisfaction is an antecedent of behavioral intentions. For the indirect path, service quality has a significant, positive influence on behavioral intentions through the customer satisfaction. The major finding of this study suggest that service quality easily attract more customers, especially the young consumers. About the sale personnel, communication skills, knowledge and ways of treatment to customers are crucial to retailers to gain competitive advantage over competitors. Therefore, it should have clear and consistent processes, procedures with criteria that create the best condition for organization and individual to open this kind of retailing store. Furthermore, product quality improvement is essential; all products must have clear originality; and diversifying products and services is also the way to appeal more consumers.

In Mash & Murrell, Diplock J said that "there is an implied warranty not merely that they shall be merchantable at the time they are put on the vessel, but that they shall be in such a state that they can endure the normal journey and be in a merchantable condition upon arrival." But in The Mercini Lady, Field J said that "the goods would be of satisfactory quality not only when the goods were delivered on to the vessel but also for a reasonable time thereafter." and "The proposed conditions were not excluded by clause 18. ${\cdots}$ clause 18 was not to be construed as extending to conditions ${\cdots}$". In relation to the problems on validity of the goods conformity clauses in FOB contracts, when considering Lord Wright's comments ("${\cdots}$ hence apt and precise words must be used to exclude it: the words guarantee or warranty are not sufficiently clear.") in Cammell Laird & Co Ltd v Manganese Bronze and Brass, FOB contracts are fundamentally one that seller's duty to deliver the goods is completing at the port of shipment and "principle of party autonomy" in Contract Law, I do not think that the terms implied by section 14 of the SGA and Common Law cannot absolutely excluded by the goods conformity clauses in sale contracts. Therefore, in order to exclude the implied terms, the parties must very clearly spell out this in the relevant clauses.

The purposes of this study were to investigate importance level and performance frequency of the dietitians' duties and task elements, to examine the actual condition of education and need for education, to analyze the interrelation between their tasks and education, and to provide the direction of education for the contracted Business & Industry (B & I) foodservice dietitians. The task elements of receiving, ordering, HACCP management and directing serving process were done almost every day. In terms of the importance of tasks, food sanitation management, personnel sanitation management, receiving and ordering were high. Meanwhile, the computerization of their works was being carried out on the whole, showing a higher frequency in all the details of procurement management and accounting management, as well as task elements such as menu planning, leftover and food waste management, HACCP management and human resource management. In the past three years, HACCP management, cost management, planning work schedule and allotting a task, general business and sale bond management were increased most and rapidly. For the actual condition of education, dietitians got more education for the duty of sanitation, safe and facility/utility management than any other duty, while they did less education of procurement management and office management than others. Meanwhile, the education for sanitation, safe and facility/utility management and accounting management were very much required. For the relationships of frequency of duty and the necessity of education, seven task elements including food sanitation management were correlated positively. Eighteen tasks besides menu planning had a significant positive correlation between the importance of duties and the necessity of education.

This study is aimed to analyze the economic performance of black rockfish aquaculture by standardizing cost structures by region and farming size. The result of survey on farming and sale condition in each region, stocking density, survival rate, juvenile price, and unit production was the highest at Yeosu and Tongyeong, Heuksando showed the lowest. While rearing period was the longest at Tongyeong, the shortest region was Yeosu and Wando. In farming cost structure by region, amount of feeing was the highest at Tongyeong and Yeosu, and the lowest was Heuksando. Cost of medicine was high in Wando and Taean region, Yeosu and Hecksando was low. In case of farm size, feed cost ratio was high in the order of medium(0.75ha), small(0.25ha) and large(1.25ha) size. Standard production cost at every farm size of Heuksando showed the lowest among these regions. Taean and Yeosu was middle, and Tongyeong and Wando was the highest. According to the income, profit rate and investment return of farm size in all regions, as the bigger farm size, the higher income and profit rate was revealed. However, in case of Wando, Taean, and Heuksando which regions has high investment return, medium farm size was higher than large size. The result of economic analysis according to various factors, economic feasibility of black rockfish aquaculture in marine floating cage was showed significant changes by rearing and market condition.

It is important to understand the biological aspects of fish for fishing management. This study was conducted from February through October 2021. A total of 1,629 fishes were collected using different fishing gears. The length-weight relationship is a power curve for all fishes and showed a significant (r² > 0.8). All fishes revealed a negative allometric growth pattern except Labeobarbus intermedius. Oreochromis niloticus (1.714 ± 0.009) was found in better condition than other fish species (analysis of variance [ANOVA], p < 0.05). The length at maturity was 24.0 cm and 25.4 cm total length (TL), 28.9 cm and 28.2 cm fork length, and 53.2 cm and 57.5 cm TL for females and males of O. niloticus, L. intermedius and Clarias gariepinus, respectively. Fecundity was ranged between 100-947 eggs/g with absolute fecundity (AF) of 468-3,832 eggs, 200-1,000 eggs/g with AF of 2,752-136,420 eggs, and 505-900 eggs/g with AF of 2,000-6,404 eggs for O. niloticus, C. gariepinus, and L. intermedius, respectively. Their respective mean fecundity was 1,490 ± 91, 23,330 ± 5,070, and 3,096 ± 273 eggs, respectively. Mean fecundity revealed a significant variation between size classes and species (ANOVA, p < 0.05). The fecundity length and fecundity-body weight relationships except (O. niloticus) of fishes were curvilinear while the gonad weight (GW)-fecundity relationship was linear for all fish species. The fecundity was moderately associated with increasing length than body weight, and GW for all fishes (r² > 0.6). In conclusion, a tangible management setup is required to sustain the use of fish in the reservoir.

The purpose of this study is to identify factors influencing fish production of shallow-sea aquaculture in South Korea. This study employed the two-way fixed effect and random effect models based on the panel models and also the difference between GMM and system GMM models based on the dynamic panel models using the amount of fish farming production, the number of stocked fry, the number of cultured fish, the amount of inputted feed, the farming area, the number of workers, and the sales price data from 2010 to 2017. First, the two-way fixed effect model of the panel models was selected by panel characteristics, time characteristics and Hausman tests and also the model was statistically significant. As a result of the two-way fixed effect model, the number of stocked fry, the amount of inputted feed, and the number of workers were identified as factors that increase the fish production of shallow-sea aquaculture. However, the number of cultured fish and the sales price were analyzed as factors that reduce the fish production of shallow-sea aquaculture. Second, the system GMM model of the dynamic panel models was selected by Hansen test and Arellano-Bond test in order to identify whether or not the over-discrimination condition is appropriate. Based on the system GMM model, the number of stocked fry, the amount of inputted feed, the number of workers in this year and 1 year ago, the number of cultured fish 2 years ago, and the sale price 3 years ago were analyzed as factors that increase the fish production of shallow-sea aquaculture. However, the amount of fish farming production 1, 2, 3 years ago, the farming area in this year, and the number of cultured fish in this year and 1 year ago were identified as factors that reduce the fish production of shallow-sea aquaculture. In conclusion, this study suggests that it is desirable to control the amount of stocked fry rather than to expand the farming area for fish farming in shallow-sea aquaculture, so as to keep the sale price at a certain level by maintaining the appropriate amount of fish production.
