2012년 7월에서 9월초까지 경상남도 연안의 해상가두리 양식장에서 사육중인 조피볼락의 대량폐사가 발생하였으며, 피해량은 1,802,000마리로 집계되었다. 폐사 해역의 수온은 최대 28.4℃까지 상승하였으며, 일간 수온변화의 폭은 최대 6.5℃로 급격한 상승과 반복적인 변화가 확인되었다. 49개 어업권 194마리를 대상으로 생물학적 질병을 조사한 결과, 일부양식장의 조피볼락에서 참돔이리도바이러스(red seabream iridovirus, RSIV), Vibrio sp.와 Vibrio spp. 또는 Microcotyle sp. 등의 주요 병원체가 확인되었다. 대량폐사의 주요 원인은 고수온과 동반하여 나타나는 반복적인 일간 수온변화, 그리고 생물학적 질병이 폐사의 증가에 영향을 미친 것으로 판단된다. From July to early September 2012, there was mass mortality of fishes, particularly black rockfish, which were being raised in the floating fish cage along the coast of Gyeongsangnam-do. The amount of damage was 1,802,000 fishes and the causes were confirmed to be rapidly rising water temperature and repeated daily changes in water temperature. The water temperature in this area of the sea rose to the maximum 28.4℃ and the daily range of changes in water temperature was maximum 6.5℃. As a result of investigating biological diseases of 194 fishes in 49 fishery areas, major pathogenic organisms such as red seabream iridovirus (RSIV), Vibrio sp. and Vibrio spp. or Microcotyle sp. were detected in rockfish in some fish farms. It is considered that the major causes of the mass mortality were high water temperature accompanied by repeated daily changes in water temperature, it is considered that biological diseases influenced the increase in the perish of fishes.

The species of Grateloupia filicina, Grateloupia divaricata in East Sea were investigated taxonmically in order to clarify taxonomic position. The ecological character, external morphology, anatomy of vegetative structure. Blade length are $15{\sim}40\;cm$, erect from discoidal holdfast of $3{\sim}10\;mm$ in diameter. Stipe $1{\sim}2.5\;cm$ long, narrowly cylindrical below, compressed above Grateloupia filicina. Main axis are long and compressed, $3{\sim}7\;mm$ broad in broadest part. Colors are scarlet to light red. Blade length are $10{\sim}25\;cm$, erect from discoidal holdfast of $3{\sim}8\;cm$ in diameter Grateloupia divaricata. Stipe are single and simple $2{\sim}5\;mm$ broad. Thallus composed of cortex and medulla in section ; cortex composed of $9{\sim}10$ layers of anticlinally arranged cortical cell, divided into outer, middle and inner parts. Partial fragments of nuclear 18S rDNAs from the two species of Grateloupia (Rhodophyta) were amplified using the PCR reaction and sequenced to compare their similarity. The partial sequences showed 98.9% similarity each other. Grateloupia filicina has 371 bp sizes and Grateloupia divaricata has 372 bp size. The G+C contents of Grateloupia filicina is 54.3% and Grateloupia divaricata is 53.64%.
