    Notes: As a result of increasing control of environmental pollution in Hong Kong. the practice of discharging untreated service-reservoir washwater to the nearest watercourse is no longer permitted. This paper describes the results of field tests on alternative methods of treating the effluents produced from cleaning fresh-water and sea-water service reservoirs in Hong Kong, including trials of alternative cleaning procedures using high-pressure jetting which were designed to (a) upgrade the cleaning efficiency and (b) reduce the resulting pollution load. The results of effluent treatment, based on pilot-plant trials incorporating various combinations of filtration and centrifugation, are presented. The option which was selected for full-scale implementation, based on a mobile centrifugation and microfiltration unit, using a membrane developed in China specifically for the water industry, is described

    Notes: Since 1993, an epizootic viral disease has occurred in net-cage cultured red sea bream, Pagrus major (Temminck & Schlegel), in Peng-hu Island located on the south-western coast of Taiwan. The diseased fish exhibited abnormal swimming and were lethargic, but few visible external signs were observed. The cumulative mortality because of the disease sometimes reached 50–90% over 2 months. Histopathogical studies of the affected fish showed enlarged basophilic cells in the gill, kidney, heart, liver and spleen. These necrotic cells were Feulgen-positive and stained blue using Giemsa. Transmission electron microscopy revealed icosahedral virions in the cytoplasm of the necrotic cells. The viral particles consisted of a central nucleocapsid (75–80 nm) and envelope, and were 120–150 nm in diameter. These results suggest that the virus belongs to the Iridoviridae. Using polymerase chain reaction (PCR), approximately 570 bp fragments were produced from the viral DNA using as a template 1-F and 1-R primers derived from red seabream iridovirus (RSIV) from red sea bream in Japan. Similar results were also obtained using nested-PCR with different primer sets (1-F, 2-R and 2-F, 1-R). Although the size and some features of epizootics of this virus differed from RSIV in Japan, it shows close genetic affinities with the latter and it is suggested that RSIV has been introduced to Taiwan.

    Notes: Summary The establishment and partial characterization of continuous cell lines fromCyprinus carpio is described. Three new cell lines designated CCT, CCG, and CCF, were established from testis, gill, and fin tissue of color carp,C. carpio, respectively. These cell lines have been subcultured more than 500 times since their initiation in May 1984. The optimal incubation temperature for growth is 31° C for CCT and 37° C for CCG and CCF. The modal chromosome numbers for CCT, CCG, and CCF cell lines are 38, 200, and 100, respectively. The duration of the cell cycle at 31° C for each cell line is 10.18 h (CCT), 15.28 h (CCG), and 18.76 h (CCF). All three cell lines are refractory to chum salmon virus. The CCT cell line is susceptible to three serotypes (Ab, Sp, and VR-299) of infectious pancreatic necrosis virus (IPNV), eel virus european, milkfish birnavirus, hard clam birnavirus, and eel herpesvirus from Formosa. In contrast, both CCG and CCF cell lines possess a very strict viral susceptibility. Only the IPNV Sp. serotype was seen to infect those two cell lines in vitro.
