This study investigated the collagen and texture properties of commonly consumed sliced raw fish species (CC-SRF) [olive flounder (OF), red seabream (RS), Atlantic salmon (AS), coho salmon (CoS) and sockeye salmon (SS)] distributed in Korea as sliced raw fishes. The crude lipid contents of CC-SRF were 5.5% for OF, 6.8% for RS, 18.5% for AS, 16.1% for CoS, and 5.7% for SS. The collagen content and solubility from CC-SRF were 622 mg/100 g and 78.0%, respectively, in OF, 270 mg/100 g and 75.6%, respectively, in RS, 237 mg/100 g and 24.1%, respectively, in AS, 341 mg/100 g and 65.7%, respectively, in CoS, and 246 mg/100 g and 17.9%, respectively, in SS. The texture of CC-SRF was affected by the lipid content, collagen content, acid solubility, hydroxylation, and cross linkage degree. The highest hardness of CC-SRF was obtained from OF, followed by RS, SS, AS and CoS. There was, however, no difference (P>0.05) in hardness between OF and RS and between AS and CoS.

This study investigated the physicochemical properties and physiological activities of jelly prepared from gelatin, sugar, bokbunja extract, and different amounts (0, 0.5, 1, 2 and 3%) of fermented sea tangle Saccharina japonica powder (FSP). The jelly moisture, pH, and sugar content slightly increased with increasing the FSP content. Hardness, springiness, gumminess, chewiness, and cohesiveness also increased with increasing FSP concentration. Jelly antioxidant activity did not change significantly with increasing FSP. In contrast, alcohol dehydrogenase and aldehyde dehydrogenase activities in the jellies increased significantly with increasing FSP concentration. β-secretase inhibitory activity in jellies also increased with increasing FSP concentration. Jellies containing 0.5 or 1% FSP achieved the highest overall sensory acceptance scores. Taken together, these data indicate that addition of FSP to jelly appears to improve its quality and physiological activities.

To develop a value-added anchovy Engraulis japonicus sauce, the processing conditions and quality characteristics of a rapidly fermented and high-purity anchovy sauce (RRAS) were examined by adding 5-10% (w/w) radish Raphanus sativus L. RRAS exhibited higher yield, total nitrogen content, and amino nitrogen and calcium contents as well as lower salinity than those of conventional anchovy sauce (control). The salinity, yield, and total amino acid contents of RRAS and control were 17.2-17.7% and 19.6%, 81.2-88.7% and 61.0%, and 13,117.8-14,174.9 mg/100 g and 10,041.1 mg/100 g, respectively. The major amino acids recorded were aspartic acid, glutamic acid, alanine, valine, isoleucine, leucine, phenylalanine, ornithine, lysine, and histidine. The histamine contents of RRAS and control were 8.3-8.6 mg/100 g and 19.2 mg/100 g, respectively, while the protease activity levels were 0.901-0.958 unit/mg and 0.695 unit/ mg, respectively. Overall, this study establishes that RRAS can not only significantly shorten the salt fermentation period, but can also serve as an anchovy sauce with superior nutritional quality and higher levels of amino acid and calcium.

This study was designed to verify the shelf-life of a freeze dried-block type of convenience food for rockfish Sebastes schlegeli seaweed soup product stored at different storing temperatures (25, 35, and 45°C) for 5 months. The polyunsaturated:saturated fatty acid ratio of the product stored at 25°C was higher than that of products stored at 35°C and 45°C for 5 months. The colorimetric assessment indicated a noticeable decrease in the brightness of product color after 5months of storage at 35°C and 45°C. Increased storage temperature and time negatively affected the product color. The products stored at 35°C and/or 45°C for more than 3 months tended to be more yellowish-red in color than those stored at 25°C for shorter periods. No disease-causing microorganisms, including Escherichia coli and Staphylococcus aureus, posing health hazards to the human, were detected on food safety evaluation, regardless of storage conditions. Based on food visual shelf life simulator the shelf life of the rockfish seaweed soup was estimated approximately 22 months, considering the data from yellowness the safety factor of 0.7.

For the safety assessment of microbiological and chemical hazards in katsuobushi, fifteen samples of katsuobushi were purchased from supermarkets. The contamination levels of total viable bacteria, coliforms, Escherichia coli, and nine pathogenic bacteria [Staphylococcus aureus, Salmonella spp., Listeria monocytogenes, Bacillus cereus, Vibrio parahaemolyticus, Clostridium perfringens, Enterohemorrhagic E. coli (EHEC), Yersinia enterocolitica and Campylobacter jejuni/coli] were quantitatively or qualitatively assessed. Additionally, the heavy metals (total and methyl mercury) content, radioactivity (131 I, 134 Cs+ and 137 Cs) were quantitatively assessed. Microbial and chemical analyses were performed using standard methods in Korean food code. The contamination level of total viable bacteria was 2.70 (1.18-4.42) log CFU/g. Coliforms, E. coli and S. aureus were not detected in any samples. Other eight pathogenic bacteria were negative in all samples. The contamination levels of total and methyl mercury were 0.366 (0.227-0.481) and 0.120 (0.002-0.241) mg/kg, respectively. In addition, radioactivity was not detected in any samples. The results will be helpful in revitalizing domestic use and boosting exports of katsuobushi because the microbiological and chemical safety of katsuobushi has been assured. Furthermore, the results may be used as a basis for performing chemical and microbial risk assessments of katsuobushi.

Squid jeotgal is a very popular traditional, salted, and fermented seafood in Korea. Due to the development of a distribution structure, a lot of imported squid jeotgal has recently entered Korea. In this study, we analyzed and compared the microbial contamination levels of domestic and imported squid jeotgal. The total viable bacterial count in domestic and imported jeotgal was 5.20 and 5.38 log CFU/g, respectively. The highest contamination level was 6.94 log CFU/g in one of the imported squid jeotgal samples. Coliforms were not detected in domestic jeotgal but were detected at 50% with 2.21 log CFU/g in imported jeotgal. Escherichia coli and Staphylococcus aureus were not detected (ND: <1 log CFU/g) in both domestic and imported jeotgal. All samples of jeotgal were negative for Bacillus cereus and Clostridium perfringens. The microbial contamination levels determined in the current study may be utilized as primary data to execute microbial risk assessments on domestic and (or) imported jeotgal.

Two long-term feeding trials were conducted to compare the effects on survival and growth of juvenile sea cucumber Apostichopus japonicus of experimental diets containing corn distillers dried grains with solubles, Squid Sepioteuthis sepioidea liver meal, and brown fish meal with a commercial die. In both first and second trials, two experimental diets and one commercial diet were assessed. After a 45-week feeding period in trial 1, survival did not differ significantly among groups. The final mean weight of sea cucumbers fed either experimental diet was significantly higher than that of sea cucumbers fed the commercial diet. After a 15-week feeding period in trial 2, survival and final mean weight of sea cucumbers fed either experimental practical diets was significantly higher than that of sea cucumbers fed the commercial diet. It was concluded that the experimental diets formulations can be used as a practical diet, and inclusion of corn distillers dried grains with solubles, squid liver meal, and brown fish meal can improve the growth of juvenile sea cucumbers.

The oxygen consumption rate (OCR) based on the water temperature and body size of the sea squirt Halocynthia roretzi was examined to provide quantitative information about the metabolic response of the species. OCRs were measured using a closed flow-through respirometer at four different water temperatures (10, 15, 20 and 25°C) and two different body sizes (21.4±1.1 g and 150.5±1.3 g, wet weight) with triplicates of each treatment. OCR increased as water temperature increased at both body sizes, but decreased as body size increased regardless of the water temperature (P<0.001). The effect of body size evaluated as a power function ranged from 0.8055 to 0.8884. The highest Q10 values in the small and large size groups ranged from 15 to 20°C and 20 to 25°C, respectively. The metabolic daily energy loss rate via respiration at all tested temperatures ranged from 56.2 to 106.1 J g-1 d-1 in the small-size group and from 44.5 to 92.0 J g-1 d-1 in the large-size group. Our results indicate that the metabolic response of H. roretzi highly depends on fluctuating water temperature at a given life stage.

Oxybenzone (Benzophenone-3; BP-3) is a compound used in sunscreens and enters the oceans due to improper disposal. It is known to disrupt the endocrine signaling in marine organisms, leading to immune and reproductive abnormalities in corals, shellfish and fishes. In this study, we investigated the effects of different concentrations of BP-3 (0, 10, 100 and 1,000 μg/L) on the fertilized eggs and hatched larvae of Oplegnathus fasciatus. The morphological changes and hatching and survival rates during embryo development were assessed. In addition, the levels of triiodothyronine (T3) were also measured. The hatched larvae exposed to BP-3 at concentrations of 10 and 100 μg/L for 24 h displayed malformation of the tail. After 36 h of exposure to BP-3, spinal deformity was observed at all tested concentrations. The hatching rate was significantly low when exposed to 100 μg/L of BP-3. A high levels of T3 was observed when the larvae were exposed to BP-3 at a concentration of 1,000 μg/L for 96 h (the end of the experiment). This may be related to increased size of larvae at 1,000 μg/L BP-3. In conclusion, our results suggested that BP-3 may interfere with embryo development, resulting in a reduction in hatching rate and malformation of larvae.

We investigated the community structure and performed detailed characterization of fish larvae assemblages collected from the southern coast of Korea in the spring and summer of 2021. The total abundance of fish larvae varied from 193.6 to 1,915.6 ind. 10 m-3. The species were distributed across 10 orders with 23 families, and 41 taxa. The dominant taxa were Gobiidae spp., Engraulis japonicus, Nibea albiflora, Sebastiscus spp., Callionymus valenciennei, Pennahia argentata, Sebastes thompsoni, Parablennius yatabei, and Platycephalus indicus. Engraulis japonicus individuals were collected from April to August and their presence contributed greatly to the total abundance of fish larvae. The total number and abundance of species peaked in early summer and the Shannon-Weaver index was in the range 0.11-1.49. Redundancy analyses revealed that the major environmental factors affecting the fish larvae assemblage differed according to the dominant taxa. Water temperature, zooplankton density, and Paracalanus parvus s. l. density were the key factors affecting the spatial and temporal distribution of fish larvae in the southern coast of Korea in spring and summer.
