  • Maillard reaction flavors had been tried by using krill hydrolysate and precursors in order to develop Teriyaki sauce with the reaction flavors. Also, the study for applying krill to Teriyaki sauce had been tried by using krill instead of eel bones. To make boiled-type and grilled-type reaction flavors, krill hydrolysate was used with other precursors such as serine, glucose and glucosamine. In the dynamic analysis of headspace volatile compounds, 20 mL reaction flavor was analyzed by the combined system of purge & trap, automatic desorber, gas chromatography and mass selective detector. Three kinds of Teriyaki sauce were developed with reaction flavor, krill and eel bones, and their products were evaluated by 10 items of cooked vegetables, cooked potatoes, boiled shrimp, grilled shrimp, fishy smell, pungent aroma, burned smell, sweety aroma, chemical smell, mud smell and preference. In the results of headspace analysis, 35 and 33 volatile compounds were identified from grilled-type and boiled-type reaction flavors. Grilled-type had sulfur-containing, aliphatic compounds, alcohols, ketones, pyrazines, and other aromatic compounds, and grilled-type had aldehydes, furans, other nitrogen-containing compounds. In the sensory evaluation of Teriyaki sauce, the items of roasted shrimp and sweety aroma showed significant differences for grilled-type application to Teriyaki sauce. The above results show the possible application of grilled-type reaction flavor to Teriyaki sauce.

  • A single specimen of Strophidon dorsalis (1,254 mm in total length), belonging to the family Muraenidae, was firstly collected in a fish trap off the coastal waters of Jindo Island in July 2018. It was characterized by having unpatterned body coloration, thin body, slightly rounded snout, two superorbital pores, three infraorbital pores, and six mandibular pores. This species is distinguishable from a morphologically similar species, S. sathete inhabiting the Korean waters by having three infraorbital pores (vs. four in S. sathete), last infraorbital pore below an anterior part of the eye (vs. below a posterior part of the eye), body depth 3.2~4.1% in total length (vs. 1.8~3.1%), and total vertebrae 154~167 (vs. 188~200). We add S. dorsalis to the Korean fish fauna and propose a new Korean name, "Seo-mang-gom-chi" for the species.

  • The aim of this research was to evaluate the biotic environments based upon the community pattern of demersal fishes in the Masan bay which is heavily polluted area in the southern part of Korea. The baited traps or bottom gillnet sampled bottom fishes at four sites totally 14 tunes from March 1994 to December 1996 with 2~3 months interval. The baited trap caught 0~ 10 species which were mainly starfish, crabs, conger eel, rockfish, or blenny with 0~50 individuals per a trap. Small crab(Atergatis sp.) was significantly dominant in the S1 site, most heavily polluted area, and starfish(Asterias sp. and/or Asterina sp.) in the other three sites. There was no animals at the S1 site in the March and July in 1994 and August in 1996. The gillnets caught 0~7 species which were mainly mantis shrimp, jellyfish, flounder, starfish, crabs, or sea weeds with 0~30 individuals per a pannel of bottom gillnet. Jellyfish was significantly dominant in the S1 site and mantis shrimp in the all four sites. There was no animals in the July 1994 at S1 site and in the August and December 1996 at S4 site. But at the August in 1995 or 1996 in the S1 site, the bottom gillnets caught mackerel, anchovy, gizzard-shad or mullet which was dead all. The species diversity index of samlings by trap or gillnet showed less than 1.0 in the 80% of the totally 56 samplings. This means that the stability of demersal fishes' community is very low owing to the poor biotic environments. But most of fishes living at Masan bay appeared well fitting with the heavily polluted environments. And some fishes, like mackerel, anchovy, gizzard-shad or mullet migrated into polluted Masan bay with the seasonal or annual fluctuation.
