조사기간 동안 경상북도 영일만 내의 총 6개 정점에서 채집된 패류는 피조개와 떡조개 2종 이었다. 패류의 총 채집개체수에서는 1,703마리, 총 생체량은 140.9 kg이었는데, 이중 떡조개가 개체수 1,198마리 (생체량 76.1 kg), 피조개가 개체수 505마리 (생체량 64.8 kg) 이었다. 채집된 주요 패류의 각장 범위는 떡조개가 25.76-67.88 mm (평균, 58.08 mm), 피조개가 46.82-113.74 mm (평균, 76.86 mm) 로서 성숙한 개체들이었다. 주요 패류의 해역별 채집량에 있어서는 항외지역이 개체수 1,332마리 (생체량 105.4 kg) 로 항내지역의 개체수 371마리 (생체량 35.5 kg) 보다 많았다. 또한, 패류의 크기에 있어서도 항외지역의 패류가 항내지역보다 큰 경향을 나타내었다. 소해면적법 (SAM) 에 의한 영일만 내의 피조개 현존량은 242톤으로 산정되었으며, 어업인들에 의해 이용되고 있는 피조개의 연 생산량은 17.93-95.53톤이었다. Bivalves collected by a dredge in Yeongil Bay of Gyeongsangbuk-Do Province, Korea in May, 2010 and August, 2010 were 2 species including Dostinorbis japonicus and Scapharca broughtonii. The total abundance of bivalves were 1,703 inds. and 140.9 kg. Among them, the abundance of D. japonicus were 1,198 inds. and 76.1 kg. And the abundance of S. broughtonii were 505 inds. and 64.8 kg. The shell length by bivalves species were 25.76-67.88 mm (mean, 58.08 mm) in D. japonicus and 46.82-113.74 mm (mean, 76.86 mm) in S. broughtonii consisting mainly of recruitment group. By regional abundance comparison, the bivalves abundance collected in the outside harbor was 1,332 inds. and 105.4 kg, which was much more than that of the inside harbor indicating 371 inds. and 35.5 kg. In terms of size, the bivalves collected in the outside harbor were 49.49-67.88 mm (mean, 58.47 mm) in D. japonicus and 48.21-113.74 mm (mean, 77.48 mm) in S. broughtonii, which were larger than those of the inside harbor. The yearly biomass of the main commercial target species, S. broughtonii by swept area method (SAM) was estimated up to 242.1 tons. However, considering the regional differences of bivalves between the inside harbor and the outside harbor by abundance and size comparison, it might have been overfished to bivalves in the inside harbor.

Stomach contents of 518 specimens of the yellow goosefish, Lophius litulon caught by the off-shore stownet in the southern waters of Korea were examined by means of the calculation of the frequency of occurrence, number and weight percentages, and index of relative importance (IRI) in each prey organisms. Prey organisms of the yellow goosefish consist of fishes, crustaceans, cephalopods. Fishes were dominant prey group, and occupied 98.8% in IRI of prey organisms. Four species of fish, Pseudosciaena manchurica, Collichthys niveatus, Engraulis japonica, Trichiurus lepturus were dominant as to the IRI and occupied 87.2% of the total IRI. P. manchurica was a dominant prey organism in predator`s stomach through the year, and the other dominant prey organisms occurred intermittently with seasonal progress. P. manchurica was a dominant prey organism to all fish size, too. C. niveatus and E. japonica decreased in importance in the diet as the fish size increased, concomitant with an increase in importance of T. lepturus. Mean species number and mean individual number of prey organisms increased with the fish size.

Age and growth of the yellow goosefish, Lophius litulon, were studied using sample collected from the southwestern waters of Korea. Vertebrae of the fish had relatively clear annuli on their surface. The opaque zone of vertebrae was formed once a year between March and April. The oldest fish observed in this study was 8 fears old for females and 5 years old far males. The relationship between the radius (R) of vertebral centrum and total length (L) was as fellows: L= 12.7+4.8R for females and L=9.8+5.6R for males, The relationship between total length and body weight (W) was as fellows: W= 0.0089L^(3.30311) far females and W=0.0329L^(2.7752) for-males. Growth in length of the fish was expressed by the von Bertalanffy`s equation as L=127.60 (1-e^-0.1228(t+0.3851)) for females and L_t=82.73 (1-e^-0.1832(t+0.6431)) males.

서해 아산만의 경기도 화성 연안 안강망어장에서 2011녈 3윌부터 2012년 2월까지 어류군집 조사를 실시하였다. 조사기간 동안 채집된 어종은 총 71종, 개체수 608,801마리 그리고 생체량은 795,503.3 g 이었다. 이중 개체수에서 멸치가 592,926마리로 전체의 97.3%를 차지하여 가장 많았다. 다음으로 흰베도라치(0.9%), 쉬쉬망둑 (0.4%), 전어 (0.2%), 줄공치(0.1%), 도화망둑(0.1)% 등이었으나 소량이었다. 생체량 면에서는 역시멸치가 622,815.8 g으로 전체의 78.2%를 차지하여 최우점하였고, 기타 쉬쉬망둑(5.1%), 꼼치 (2.4%), 문치가자미(2.2%), 홍어(1.8%) 등의 순이었다. 표층해역에서 채집된 어류는 총 59종, 개체수 190,406마리, 생체량 241,113.4 g이었으며, 저층해역에서는 총 61종, 개체수 418,395마리, 생 체량 554,389.9 g의 어류가 채집되었다. 어류군집은 계절에 따라 많이 달랐는데, 어종수가 많았던 2011년 3월부터 5월 그리고 2012년 1원과 2월에는 개체수와 생체량이 적었으며, 대신에 어종수가 적었던 2011년 6월부터 12월까지는 개체 수와 생체량이 많이 증가하였다. 이는 우점종인 멸치의 어장가입과 주로 관련이 있었다. Species composition, abundance and seasonal variation of the fish community in the water off Hwaseong City, the West Sea, Korea were determined using monthly samples collected by a stow net from March 2011 to February 2012. A total of 71 species, 608,801 individuals and 795,503.3g of fish were collected during the study. Domi-nant species were Engraulis japonicus accounting for 97.3% (592,926 individuals) in total number of individuals and 78.2% (622,815.8g) in total biomass. The other major species were Pholis fangi, Chae-turichthys stigmatias, Konosirus punctatus, Hyporhamphus intermedius, Amblychaeturichthys hexanema, Liparis tanakai, Pleuronectes yokohamae and Okamejei kenojei. Fish collected were 59 species, 190,406 individuals and 241,113.4 g in the surface stow net and 61 species, 418,395 individuals and 554,189.9 g in the bottom stow net. Catch rate was low from march to May although the number of species was high. Catch rate signifi-cantly increased from June, but the number of species was relatively low.
