The baby fish oxygen consumption of E. fario under different conditions were measured and studied. The results are showed as follows: That the higher the water temperature is, the higher the rate of baby fish oxygen consumption of E. fario is. At 17.6 °C, and body weight 25.625~28.111 g , the rate of oxygen consumption is 1.517 μg/(g·min); at 24.5 °C, the rate of oxygen consumption is 3.202 μg/(g·min); at 33.4 °C, the rate of oxygen consumption reaches 7.230 μg/(g·min) .

The baby fish oxygen consumption of E. fario under different conditions were measured and studied. The results are showed as follows: That the higher the water temperature is, the higher the rate of baby fish oxygen consumption of E. fario is. At 17.6 °C, and body weight 25.625~28.111 g , the rate of oxygen consumption is 1.517 μg/(g·min); at 24.5 °C, the rate of oxygen consumption is 3.202 μg/(g·min); at 33.4 °C, the rate of oxygen consumption reaches 7.230 μg/(g·min) . The water temperature within the range of 21~27 °C, has the least effects on the rate of the oxygen consumption.Only under a special range of dissolved oxygen (lower than 1.8 mg/L), change in the dissolved oxygen affects the rate of oxygen consumption of E. fario. As the dissolved oxygen is less than 1.8 mg/L, the rate of the oxygen consumption showed rapid decrease. When the amount of dissolved oxygen is higher than 1.8 mg/L, the rate of oxygen consumption is hardly affected. The relation between the rate of oxygen consumption ( Y ) and the dissolved oxygen ( X ) may be expressed as: Y=0.198 4X 3-1.734 8X 2+4.869 3X-1.549. Within a whole day, from 17:00 to 09:00, the rate of oxygen consumption of E. fario decreases continuously, and from 09:00 to 17:00, the rate increases in succession.And under the active condition, the rate of oxygen consumption is 38.50% higher than under quietude.

Two methods,tagging and ink injection,were used in grouper marking.The studied fishes were juvenile of Epinephelus akaara and Epinephelus awoara both artificially produced and caught from natural waters and their wild adults.Results showed that the fishes inhabited where released;both juvenile and adult ones moved in an area of 2n mile diameter after651days and48days of releasing,respectively.As far as the tagging method is concerned,we found that the tagged fishes could only be recaptured in the year when released;but with injection method,it was reported that the fishes could be caught in the1st,2nd and3rd years.It was confirmed in the cement tank where tagged fishes lost1/3tags.That means tagging method shall not adapt to the release research,while the injection method is good for it.Generally,the recaptured rates of injected fishes were1.4%~4.5%,3.1%~13.4%,0.7%in the1st.2nd,3rd years,respectively.

使用体外挂标志牌和体内注射着色液(入墨法)方法对赤点石斑鱼Epinephelusakaara和青石斑鱼Epinephelusawoara幼鱼(人工培育幼鱼和野生幼鱼)和野生成鱼进行标志放流试验。结果表明:石斑鱼幼鱼和成鱼移动范围不大,幼鱼最长经651d、成鱼最长经48d的移动均在2nmile以内,其栖息习性均具有明显的地域性。挂牌标志法只获得放流当年重捕记录,入墨法获得当年、第二年和第三年的重捕记录,室内水泥池暂养标志鱼有1/3标志牌脱落,说明体外挂牌标志对石斑鱼不太适合。放流入墨法标志幼鱼各水域重捕率第一年1.4%~4.5%、第二年3.1%~13.4%、第三年0.7%。此标志法对研究群体生长较理想。

The paper reports the results of the studies on nursery technique of the young fish of Epinephelus coioides. The crucial importance of the nursery technique was separate the young fish according to there sizes in time. It took 45 days for rearing 2 broods of the fish. A sort of artificial formula food was used to rear the fish. During the experimental period the average total length of 2 broods of young fish increased from 27mm and 28mm to 75.7mm and 82.1mm respectively, while the average body weight of them...
