The mugilidae fishes are common euryhaline species that live in coastal marine waters to freshwater areas. The taxonomy and nomenclature of the mugilidae fishes still remain unresolved because of their morphological similarities. Among the mugilidae fishes, most commonly consumed in Korea, are grey mullet (Mugil cephalus) and red lip mullet (Chelon haematocheilus). It is generally called 'mullet' without distinguishing between two mullets. Therefore, the aim of this study is to examine the scientific names and common names of mullet species used in Korea from the domestic journals and Korean old documents. The scientific name of grey mullet is M. cephalus, but that of redlip mullet is C. haematocheilus. But the genus of redlip mullet is still mixed with Chelon, Mugil, and Liza. The standard name of two mullet is not distinguished in the Korean dictionary, but they were clearly distinguished in the Japanese, English, and Chinese dictionaries. In the ancient Korean references, the mullet was called 'Chieo' or 'Sueo'. In most of the old literature, the distinction between grey mullet and redlip mullet is not clear. However, in Jasaneobo, it was written separately from grey mullet and redlip mullet, and attaching "ga" was different from now. The Korean standard name of redlip mullet is 'gasungeo', however, the fishermen in Jeollado and Gyoungsangdo call it 'chamsungeo'. Considering the negative perception of 'ga' character, it is proposed to change 'cham(眞)' instead of 'ga(假)' to improve economic value of red lip mullet.

The taxonomic revision of the family Mugilidae from Korea was made based on the fish specimens collected from the coasts of the Korea from July 1990 to July 1994. The family Mugilidae was classified into three species belonging to two genera: Mugil cephalus, Liza haematocheilus and Liza carinatus. Previousely Mugil japonicus reported as a species from Korea was confirmed into junior synonym of Mugil cephalus. based on the external and internal morphological characters. A new key to the genera and species of family Mugilidae was proposed and described their distribution in Korea.

Three specimens of Moolgarda seheli were collected for the first time from the southern coastal waters of Jeju Island in October 2010. This species is characterized by scales with a flexible membranous edge, a distinctive dark dot on the upper axis of the pectoral fin base, 39 lateral line scales, and 24~25 vertebrae. The newly proposed Korean name of the genus Moolgarda is "Cho-seung-kkori-sung-eo-sok" and that of M. seheli is "Cho-seung-kko-ri-sung-eo".

Two specimens of Chelon macrolepis were collected from southern coastal waters of Jeju Island and Busan in February 2007 and October 2010, and it, herein, described as an unrecorded species from Korea. Chelon macrolepis is characterized by posterior tip of maxilla exposed when mouth closed, having 31~32 lateral line scales, and 23~24 vertebrae. The new Korean name is proposed as "Keun-bi-neul-sung-eo" for Chelon macrolepis.

The lethal concentration(LC50) of several micropollutants for three species of the fish Paralichthys olivaceus, Mugil cephalus and Sebastes schlegeli were determined by acute toxicity tests. For the determination of definitive test concentrations, the fish were exposed to three test material concentrations spaced at order-of-magnitude intervals based on a logarithmic ratio in range finding tests. LC50 was determined by five concentrations of test material in a geometric progression by means of range finding tests. The 96hr-LC50 values(mg/l) were estimated by the graphical interpolation of probability-logarithm transformations. These indicated that the order of sensitivities to three kind of micropollutants was Mugil cephalus > Paralichthys olivaceus > Sebastes schlegeli.

Physiological responses (cortisol, glucose, GPT, GOT, total protein, hematocrit, sodium, chloride, potassium, total calcium and osmolality), growth and survival rates of grey mullet (Mugil cephalus) and Nile tilapia (Oreochromis niloticus) by the manipulation of salinity were studied. Salinity was increased directly from freshwater to $33\%_{\circ}$ and remained for 15 days. Then, salinity was decreased directly from seawater to freshwater and remained for other 15 days. All tilapias were dead at the third day, but $96.5\%$ of grey mullet were survived at the 30th day. The grey mullet showed no significant differences for cortisol and glucose concentrations in the seawater and freshwater. However, those of the Nile tilapia were increased in seawater. The grey mullet showed no significant differences for sodium, chloride and potassium concentrations during experimental period. However, those of the Nile tilapia were significantly increased when exposed to seawater. The osmolality of grey mullet ranged between 293.5 mOsm/kg and 335.0 mOsm/kg for the whole experimental period.

Changes of gill tissue and body composition of grey mullet (Mugil cephalus) and Nile tilapia (Oreochromis niloticus) by the manipulation of salinity were observed in a recirculating rearing system. Salinity was increased from $0\%_{\circ}$ to $33\%_{\circ}$for 1 day and remained far 15days, thereafter salinity was decreased from $33\%_{\circ}$ to $0\%_{\circ{$ for 1 day and remained for other 15 days. Any morphological differences of gill lamella in grey mullet were not observed in seawater and freshwater. However, on day 2 in exposure to seawater, Nile tilapia showed the edema and bloodclot in gill lamella. In the case of grey mullet, mitochondria and tubular system of chloride cell were more densely packed according to the salinity increase. The whole body of grey mullet showed no significant differences in moisture content during experimental period. However, moisture content in whole body of the Nile tilapia was signincantly decreased when exposed to seawater. Protein content in whole body of grey mullet showed no significant difference between beginning and day 15 of the experiment.

The total amount of lipid content in the mullet roe is 20.5%, and iodine value and unsaponifiable matters content are 118 and 38.7%, respectively. The lipid composition of the muscle, roe and liver of the mullet, Mugil cephalus, shows differences. Triglyceride, wax esters, and free fatty acids are mainly contained in the lipids of the muscle, roe and liver, respectively. The mullet roe lipids are mainly composed of 59.1% of wax esters with a trace of sterol esters, 26.9% of polar lipids with pigments, 9.0% of triglyceride plus a trace of free fatty alcohols and fatty acids, and 3.0% of sterol contaminated with a trace of fatty alcohols. The major fatty acids of wax esters are C16 : 0, 47.5%, C18 : 1, 23.0%, C16 : 3, 6.5%, C20 : 5, 4.0%, those of triglyceride are C16 : 1, 25.1%, C18: 1, 16.7%, C16 : 0, 16.3%, C22 : 1, 7.9%, C18 : 0, 5.5%, C22 : 6, 4.4%, and those of polar lipids are C16 : 0, 35.0%, C18 : 1, 24.7%, C16 : 1, 6.1%, C20 : 5, 5.3%, C22 : 6, 4.2%. The major alcohols of wax esters are 51.0% of cetyl alcohol, 18.2% of palmitoleyl alcohol, and 10.7% of oleyl alcohol, and considerable amounts of odd-numbered alcohols such as C15 : 0, C15 : 1, C17 : 0, C17 : 1 and C19 : 1 are also found.

The salted-dried mullet (Mugil japonicus) roe is a kind of traditional food particulary in the area of Young-am gun, Chunnam province. The manufactruring method was that the fresh roe was salted by clean wasters, drained, shaped a flat piece with 1.2cm thickness by pressing, and spreaded sesame oils on the surface of the salted roe periodically during wind drying for 20 days. The dried roe was blanched in heated water$(80^{\circ}C/3min.)$ and packaged the dried product for the cooling storages. The fractional compositions of free lipid were 40% of neutral lipids, 12% of glycolipids and 9% of phospholipids and those of bound lipids were 13% of neutral lipids, 10% of glycolipids and 13% of phospholipids in wind drying method. The major fatty acids of the neatral lipids were $C_{16:0},\;C_{18:0},\;C_{18:2},\;C_{18:2}\;and\;C_{20:0}$ which was consisted of free and bound lipids. As the major fatty acid amount of neutral lipids was 30.1% in free lipid, and 11.0% in bound lipid, the nsaturated fatty acid degree(TUFA/TSFA)was 1.12-1.14, the polyenoic acid degree (TPEA/TMEA), 0.32-1.20 and the total essential fatty acid (TEFA), 11.33%.
